Smart firewall iPhone app promises to put your privacy before profits

you-asked-am-i-addicted-to-my-phone

For weeks, a small team of security researchers and developers have been putting the finishing touches on a new privacy app, which its founder says can nix some of the hidden threats that mobile users face — often without realizing.

Phones track your location, apps siphon off our data, and aggressive ads try to grab your attention. Your phone has long been a beacon of data, broadcasting to ad networks and data trackers, trying to build up profiles on you wherever you go to sell you things you’ll never want.

Will Strafach  knows that all too well. A security researcher and former iPhone jailbreaker, Strafach has shifted his time digging into apps for insecure, suspicious and unethical behavior. Last year, he found AccuWeather was secretly sending precise location data without a user’s permission. And just a few months ago, he revealed a list of dozens of apps that were sneakily siphoning off their users’ tracking data to data monetization firms without their users’ explicit consent.

Now his team — including co-founder Joshua Hill and chief operating officer Chirayu Patel — will soon bake those findings into its new “smart firewall” app, which he says will filter and block traffic that invades a user’s privacy.

“We’re in a ‘wild west’ of data collection,” he said, “where data is flying out from your phone under the radar — not because people don’t care but there’s no real visibility and people don’t know it’s happening,” he told me in a call last week.

At its heart, the Guardian Mobile Firewall — currently in a closed beta — funnels all of an iPhone or iPad’s internet traffic through an encrypted virtual private network (VPN) tunnel to Guardian’s servers, outsourcing all of the filtering and enforcement to the cloud to help reduce performance issues on the device’s battery. It means the Guardian app can near-instantly spot if another app is secretly sending a device’s tracking data to a tracking firm, warning the user or giving the option to stop it in its tracks. The aim isn’t to prevent a potentially dodgy app from working properly, but to give users’ awareness and choice over what data leaves their device.

Strafach described the app as “like a junk email filter for your web traffic,” and you can see from of the app’s dedicated tabs what data gets blocked and why. A future version plans to allow users to modify or block their precise geolocation from being sent to certain servers. Strafach said the app will later tell a user how many times an app accesses device data, like their contact lists.

But unlike other ad and tracker blockers, the app doesn’t use overkill third-party lists that prevent apps from working properly. Instead, taking a tried-and-tested approach from the team’s own research. The team periodically scans a range of apps in the App Store to help identify problematic and privacy-invasive issues that are fed to the app to help improve over time. If an app is known to have security issues, the Guardian app can alert a user to the threat. The team plans to continue building machine learning models that help to identify new threats — including so-called “aggressive ads” — that hijack your mobile browser and redirect you to dodgy pages or apps.

Strafach said that the app will “err on the side of usability” by warning users first — with the option of blocking it. A planned future option will allow users to go into a higher, more restrictive privacy level — “Lockdown mode” — which will deny bad traffic by default until the user intervenes.

What sets the Guardian app from its distant competitors is its anti-data collection.

Whenever you use a VPN — to evade censorship, site blocks or surveillance — you have to put more trust in the VPN server to keep all of your internet traffic safe than your internet provider or cell carrier. Strafach said that neither he nor the team wants to know who uses the app. The less data they have, the less they know, and the safer and more private its users are.

“We don’t want to collect data that we don’t need,” said Strafach. “We consider data a liability. Our rule is to collect as little as possible. We don’t even use Google Analytics or any kind of tracking in the app — or even on our site, out of principle.”

The app works by generating a random set of VPN credentials to connect to the cloud. The connection uses IPSec (IKEv2) with a strong cipher suite, he said. In other words, the Guardian app isn’t a creepy VPN app like Facebook’s Onavo, which Apple pulled from the App Store for collecting data it shouldn’t have been. “On the server side, we’ll only see a random device identifier, because we don’t have accounts so you can’t be attributable to your traffic,” he said.

“We don’t even want to say ‘you can trust us not to do anything,’ because we don’t want to be in a position that we have to be trusted,” he said. “We really just want to run our business the old fashioned way. We want people to pay for our product and we provide them service, and we don’t want their data or send them marketing.”

“It’s a very hard line,” he said. “We would shut down before we even have to face that kind of decision. It would go against our core principles.”

I’ve been using the app for the past week. It’s surprisingly easy to use. For a semi-advanced user, it can feel unnatural to flip a virtual switch on the app’s main screen and allow it to run its course. Anyone who cares about their security and privacy are often always aware of their “opsec” — one wrong move and it can blow your anonymity shield wide open. Overall, the app works well. It’s non-intrusive, it doesn’t interfere, but with the “VPN” icon lit up at the top of the screen, there’s a constant reminder that the app is working in the background.

It’s impressive how much the team has kept privacy and anonymity so front of mind throughout the app’s design process — even down to allowing users to pay by Apple Pay and through in-app purchases so that no billing information is ever exchanged.

The app doesn’t appear to slow down the connection when browsing the web or scrolling through Twitter or Facebook, on neither LTE or a Wi-Fi network. Even streaming a medium-quality live video stream didn’t cause any issues. But it’s still early days, and even though the closed beta has a few hundred users — myself included — as with any bandwidth-intensive cloud service, the quality could fluctuate over time. Strafach said that the backend infrastructure is scalable and can plug-and-play with almost any cloud service in the case of outages.

In its pre-launch state, the company is financially healthy, scoring a round of initial seed funding to support getting the team together, the app’s launch, and maintaining its cloud infrastructure. Steve Russell, an experienced investor and board member, said he was “impressed” with the team’s vision and technology.

“Quality solutions for mobile security and privacy are desperately needed, and Guardian distinguishes itself both in its uniqueness and its effectiveness,” said Russell in an email.

He added that the team is “world class,” and has built a product that’s “sorely needed.”

Strafach said the team is running financially conservatively ahead of its public reveal, but that the startup is looking to raise a Series A to support its anticipated growth — but also the team’s research that feeds the app with new data. “There’s a lot we want to look into and we want to put out more reports on quite a few different topics,” he said.

As the team continue to find new threats, the better the app will become.

The app’s early adopter program is open, including its premium options. The app is expected to launch fully in December.

How Companies Learn Your Secrets

Andrew Pole had just started working as a statistician for Target in 2002, when two colleagues from the marketing department stopped by his desk to ask an odd question: “If we wanted to figure out if a customer is pregnant, even if she didn’t want us to know, can you do that? ”

Pole has a master’s degree in statistics and another in economics, and has been obsessed with the intersection of data and human behavior most of his life. His parents were teachers in North Dakota, and while other kids were going to 4-H, Pole was doing algebra and writing computer programs. “The stereotype of a math nerd is true,” he told me when I spoke with him last year. “I kind of like going out and evangelizing analytics.”

As the marketers explained to Pole — and as Pole later explained to me, back when we were still speaking and before Target told him to stop — new parents are a retailer’s holy grail. Most shoppers don’t buy everything they need at one store. Instead, they buy groceries at the grocery store and toys at the toy store, and they visit Target only when they need certain items they associate with Target — cleaning supplies, say, or new socks or a six-month supply of toilet paper. But Target sells everything from milk to stuffed animals to lawn furniture to electronics, so one of the company’s primary goals is convincing customers that the only store they need is Target. But it’s a tough message to get across, even with the most ingenious ad campaigns, because once consumers’ shopping habits are ingrained, it’s incredibly difficult to change them.

There are, however, some brief periods in a person’s life when old routines fall apart and buying habits are suddenly in flux. One of those moments — the moment, really — is right around the birth of a child, when parents are exhausted and overwhelmed and their shopping patterns and brand loyalties are up for grabs. But as Target’s marketers explained to Pole, timing is everything. Because birth records are usually public, the moment a couple have a new baby, they are almost instantaneously barraged with offers and incentives and advertisements from all sorts of companies. Which means that the key is to reach them earlier, before any other retailers know a baby is on the way. Specifically, the marketers said they wanted to send specially designed ads to women in their second trimester, which is when most expectant mothers begin buying all sorts of new things, like prenatal vitamins and maternity clothing. “Can you give us a list?” the marketers asked.

“We knew that if we could identify them in their second trimester, there’s a good chance we could capture them for years,” Pole told me. “As soon as we get them buying diapers from us, they’re going to start buying everything else too. If you’re rushing through the store, looking for bottles, and you pass orange juice, you’ll grab a carton. Oh, and there’s that new DVD I want. Soon, you’ll be buying cereal and paper towels from us, and keep coming back.”

The desire to collect information on customers is not new for Target or any other large retailer, of course. For decades, Target has collected vast amounts of data on every person who regularly walks into one of its stores. Whenever possible, Target assigns each shopper a unique code — known internally as the Guest ID number — that keeps tabs on everything they buy. “If you use a credit card or a coupon, or fill out a survey, or mail in a refund, or call the customer help line, or open an e-mail we’ve sent you or visit our Web site, we’ll record it and link it to your Guest ID,” Pole said. “We want to know everything we can.”

Also linked to your Guest ID is demographic information like your age, whether you are married and have kids, which part of town you live in, how long it takes you to drive to the store, your estimated salary, whether you’ve moved recently, what credit cards you carry in your wallet and what Web sites you visit. Target can buy data about your ethnicity, job history, the magazines you read, if you’ve ever declared bankruptcy or got divorced, the year you bought (or lost) your house, where you went to college, what kinds of topics you talk about online, whether you prefer certain brands of coffee, paper towels, cereal or applesauce, your political leanings, reading habits, charitable giving and the number of cars you own. (In a statement, Target declined to identify what demographic information it collects or purchases.) All that information is meaningless, however, without someone to analyze and make sense of it. That’s where Andrew Pole and the dozens of other members of Target’s Guest Marketing Analytics department come in.

Almost every major retailer, from grocery chains to investmentbanks to the U.S. Postal Service, has a “predictive analytics” department devoted to understanding not just consumers’ shopping habits but also their personal habits, so as to more efficiently market to them. “But Target has always been one of the smartest at this,” says Eric Siegel, a consultant and the chairman of a conference called Predictive Analytics World. “We’re living through a golden age of behavioral research. It’s amazing how much we can figure out about how people think now.”

The reason Target can snoop on our shopping habits is that, over the past two decades, the science of habit formation has become a major field of research in neurology and psychology departments at hundreds of major medical centers and universities, as well as inside extremely well financed corporate labs. “It’s like an arms race to hire statisticians nowadays,” said Andreas Weigend, the former chief scientist at Amazon.com. “Mathematicians are suddenly sexy.” As the ability to analyze data has grown more and more fine-grained, the push to understand how daily habits influence our decisions has become one of the most exciting topics in clinical research, even though most of us are hardly aware those patterns exist. One study from Duke University estimated that habits, rather than conscious decision-making, shape 45 percent of the choices we make every day, and recent discoveries have begun to change everything from the way we think about dieting to how doctors conceive treatments for anxiety, depression and addictions.

This research is also transforming our understanding of how habits function across organizations and societies. A football coach named Tony Dungy propelled one of the worst teams in the N.F.L. to the Super Bowl by focusing on how his players habitually reacted to on-field cues. Before he became Treasury secretary, Paul O’Neill overhauled a stumbling conglomerate, Alcoa, and turned it into a top performer in the Dow Jones by relentlessly attacking one habit — a specific approach to worker safety — which in turn caused a companywide transformation. The Obama campaign has hired a habit specialist as its “chief scientist” to figure out how to trigger new voting patterns among different constituencies.

Researchers have figured out how to stop people from habitually overeating and biting their nails. They can explain why some of us automatically go for a jog every morning and are more productive at work, while others oversleep and procrastinate. There is a calculus, it turns out, for mastering our subconscious urges. For companies like Target, the exhaustive rendering of our conscious and unconscious patterns into data sets and algorithms has revolutionized what they know about us and, therefore, how precisely they can sell.

Inside the brain-and-cognitive-sciences department of the Massachusetts Institute of Technology are what, to the casual observer, look like dollhouse versions of surgical theaters. There are rooms with tiny scalpels, small drills and miniature saws. Even the operating tables are petite, as if prepared for 7-year-old surgeons. Inside those shrunken O.R.’s, neurologists cut into the skulls of anesthetized rats, implanting tiny sensors that record the smallest changes in the activity of their brains.

An M.I.T. neuroscientist named Ann Graybiel told me that she and her colleagues began exploring habits more than a decade ago by putting their wired rats into a T-shaped maze with chocolate at one end. The maze was structured so that each animal was positioned behind a barrier that opened after a loud click. The first time a rat was placed in the maze, it would usually wander slowly up and down the center aisle after the barrier slid away, sniffing in corners and scratching at walls. It appeared to smell the chocolate but couldn’t figure out how to find it. There was no discernible pattern in the rat’s meanderings and no indication it was working hard to find the treat.

The probes in the rats’ heads, however, told a different story. While each animal wandered through the maze, its brain was working furiously. Every time a rat sniffed the air or scratched a wall, the neurosensors inside the animal’s head exploded with activity. As the scientists repeated the experiment, again and again, the rats eventually stopped sniffing corners and making wrong turns and began to zip through the maze with more and more speed. And within their brains, something unexpected occurred: as each rat learned how to complete the maze more quickly, its mental activity decreased. As the path became more and more automatic — as it became a habit — the rats started thinking less and less.

This process, in which the brain converts a sequence of actions into an automatic routine, is called “chunking.” There are dozens, if not hundreds, of behavioral chunks we rely on every day. Some are simple: you automatically put toothpaste on your toothbrush before sticking it in your mouth. Some, like making the kids’ lunch, are a little more complex. Still others are so complicated that it’s remarkable to realize that a habit could have emerged at all.

Take backing your car out of the driveway. When you first learned to drive, that act required a major dose of concentration, and for good reason: it involves peering into the rearview and side mirrors and checking for obstacles, putting your foot on the brake, moving the gearshift into reverse, removing your foot from the brake, estimating the distance between the garage and the street while keeping the wheels aligned, calculating how images in the mirrors translate into actual distances, all while applying differing amounts of pressure to the gas pedal and brake.

Now, you perform that series of actions every time you pull into the street without thinking very much. Your brain has chunked large parts of it. Left to its own devices, the brain will try to make almost any repeated behavior into a habit, because habits allow our minds to conserve effort. But conserving mental energy is tricky, because if our brains power down at the wrong moment, we might fail to notice something important, like a child riding her bike down the sidewalk or a speeding car coming down the street. So we’ve devised a clever system to determine when to let a habit take over. It’s something that happens whenever a chunk of behavior starts or ends — and it helps to explain why habits are so difficult to change once they’re formed, despite our best intentions.

To understand this a little more clearly, consider again the chocolate-seeking rats. What Graybiel and her colleagues found was that, as the ability to navigate the maze became habitual, there were two spikes in the rats’ brain activity — once at the beginning of the maze, when the rat heard the click right before the barrier slid away, and once at the end, when the rat found the chocolate. Those spikes show when the rats’ brains were fully engaged, and the dip in neural activity between the spikes showed when the habit took over. From behind the partition, the rat wasn’t sure what waited on the other side, until it heard the click, which it had come to associate with the maze. Once it heard that sound, it knew to use the “maze habit,” and its brain activity decreased. Then at the end of the routine, when the reward appeared, the brain shook itself awake again and the chocolate signaled to the rat that this particular habit was worth remembering, and the neurological pathway was carved that much deeper.

The process within our brains that creates habits is a three-step loop. First, there is a cue, a trigger that tells your brain to go into automatic mode and which habit to use. Then there is the routine, which can be physical or mental or emotional. Finally, there is a reward, which helps your brain figure out if this particular loop is worth remembering for the future. Over time, this loop — cue, routine, reward; cue, routine, reward — becomes more and more automatic. The cue and reward become neurologically intertwined until a sense of craving emerges. What’s unique about cues and rewards, however, is how subtle they can be. Neurological studies like the ones in Graybiel’s lab have revealed that some cues span just milliseconds. And rewards can range from the obvious (like the sugar rush that a morning doughnut habit provides) to the infinitesimal (like the barely noticeable — but measurable — sense of relief the brain experiences after successfully navigating the driveway). Most cues and rewards, in fact, happen so quickly and are so slight that we are hardly aware of them at all. But our neural systems notice and use them to build automatic behaviors.

Habits aren’t destiny — they can be ignored, changed or replaced. But it’s also true that once the loop is established and a habit emerges, your brain stops fully participating in decision-making. So unless you deliberately fight a habit — unless you find new cues and rewards — the old pattern will unfold automatically.

“We’ve done experiments where we trained rats to run down a maze until it was a habit, and then we extinguished the habit by changing the placement of the reward,” Graybiel told me. “Then one day, we’ll put the reward in the old place and put in the rat and, by golly, the old habit will re-emerge right away. Habits never really disappear.”

Luckily, simply understanding how habits work makes them easier to control. Take, for instance, a series of studies conducted a few years ago at Columbia University and the University of Alberta. Researchers wanted to understand how exercise habits emerge. In one project, 256 members of a health-insurance plan were invited to classes stressing the importance of exercise. Half the participants received an extra lesson on the theories of habit formation (the structure of the habit loop) and were asked to identify cues and rewards that might help them develop exercise routines.

The results were dramatic. Over the next four months, those participants who deliberately identified cues and rewards spent twice as much time exercising as their peers. Other studies have yielded similar results. According to another recent paper, if you want to start running in the morning, it’s essential that you choose a simple cue (like always putting on your sneakers before breakfast or leaving your running clothes next to your bed) and a clear reward (like a midday treat or even the sense of accomplishment that comes from ritually recording your miles in a log book). After a while, your brain will start anticipating that reward — craving the treat or the feeling of accomplishment — and there will be a measurable neurological impulse to lace up your jogging shoes each morning.

Our relationship to e-mail operates on the same principle. When a computer chimes or a smartphone vibrates with a new message, the brain starts anticipating the neurological “pleasure” (even if we don’t recognize it as such) that clicking on the e-mail and reading it provides. That expectation, if unsatisfied, can build until you find yourself moved to distraction by the thought of an e-mail sitting there unread — even if you know, rationally, it’s most likely not important. On the other hand, once you remove the cue by disabling the buzzing of your phone or the chiming of your computer, the craving is never triggered, and you’ll find, over time, that you’re able to work productively for long stretches without checking your in-box.

Some of the most ambitious habit experiments have been conducted by corporate America. To understand why executives are so entranced by this science, consider how one of the world’s largest companies, Procter & Gamble, used habit insights to turn a failing product into one of its biggest sellers. P.& G. is the corporate behemoth behind a whole range of products, from Downy fabric softener to Bounty paper towels to Duracell batteries and dozens of other household brands. In the mid-1990s, P.& G.’s executives began a secret project to create a new product that could eradicate bad smells. P.& G. spent millions developing a colorless, cheap-to-manufacture liquid that could be sprayed on a smoky blouse, stinky couch, old jacket or stained car interior and make it odorless. In order to market the product — Febreze — the company formed a team that included a former Wall Street mathematician named Drake Stimson and habit specialists, whose job was to make sure the television commercials, which they tested in Phoenix, Salt Lake City and Boise, Idaho, accentuated the product’s cues and rewards just right.

TimesCast | Retailers‘ Predictions

February 16, 2012 – In a preview of this Sunday’s New York Times Magazine, Charles Duhigg details how some retailers profit by predicting major changes in your life.

By Kassie Bracken on Publish Date February 17, 2012. . Watch in Times Video »

The first ad showed a woman complaining about the smoking section of a restaurant. Whenever she eats there, she says, her jacket smells like smoke. A friend tells her that if she uses Febreze, it will eliminate the odor. The cue in the ad is clear: the harsh smell of cigarette smoke. The reward: odor eliminated from clothes. The second ad featured a woman worrying about her dog, Sophie, who always sits on the couch. “Sophie will always smell like Sophie,” she says, but with Febreze, “now my furniture doesn’t have to.” The ads were put in heavy rotation. Then the marketers sat back, anticipating how they would spend their bonuses. A week passed. Then two. A month. Two months. Sales started small and got smaller. Febreze was a dud.

The panicked marketing team canvassed consumers and conducted in-depth interviews to figure out what was going wrong, Stimson recalled. Their first inkling came when they visited a woman’s home outside Phoenix. The house was clean and organized. She was something of a neat freak, the woman explained. But when P.& G.’s scientists walked into her living room, where her nine cats spent most of their time, the scent was so overpowering that one of them gagged.

According to Stimson, who led the Febreze team, a researcher asked the woman, “What do you do about the cat smell?”

“It’s usually not a problem,” she said.

“Do you smell it now?”

“No,” she said. “Isn’t it wonderful? They hardly smell at all!”

A similar scene played out in dozens of other smelly homes. The reason Febreze wasn’t selling, the marketers realized, was that people couldn’t detect most of the bad smells in their lives. If you live with nine cats, you become desensitized to their scents. If you smoke cigarettes, eventually you don’t smell smoke anymore. Even the strongest odors fade with constant exposure. That’s why Febreze was a failure. The product’s cue — the bad smells that were supposed to trigger daily use — was hidden from the people who needed it the most. And Febreze’s reward (an odorless home) was meaningless to someone who couldn’t smell offensive scents in the first place.

P.& G. employed a Harvard Business School professor to analyze Febreze’s ad campaigns. They collected hours of footage of people cleaning their homes and watched tape after tape, looking for clues that might help them connect Febreze to people’s daily habits. When that didn’t reveal anything, they went into the field and conducted more interviews. A breakthrough came when they visited a woman in a suburb near Scottsdale, Ariz., who was in her 40s with four children. Her house was clean, though not compulsively tidy, and didn’t appear to have any odor problems; there were no pets or smokers. To the surprise of everyone, she loved Febreze.

“I use it every day,” she said.

“What smells are you trying to get rid of?” a researcher asked.

“I don’t really use it for specific smells,” the woman said. “I use it for normal cleaning — a couple of sprays when I’m done in a room.”

The researchers followed her around as she tidied the house. In the bedroom, she made her bed, tightened the sheet’s corners, then sprayed the comforter with Febreze. In the living room, she vacuumed, picked up the children’s shoes, straightened the coffee table, then sprayed Febreze on the freshly cleaned carpet.

“It’s nice, you know?” she said. “Spraying feels like a little minicelebration when I’m done with a room.” At the rate she was going, the team estimated, she would empty a bottle of Febreze every two weeks.

When they got back to P.& G.’s headquarters, the researchers watched their videotapes again. Now they knew what to look for and saw their mistake in scene after scene. Cleaning has its own habit loops that already exist. In one video, when a woman walked into a dirty room (cue), she started sweeping and picking up toys (routine), then she examined the room and smiled when she was done (reward). In another, a woman scowled at her unmade bed (cue), proceeded to straighten the blankets and comforter (routine) and then sighed as she ran her hands over the freshly plumped pillows (reward). P.& G. had been trying to create a whole new habit with Febreze, but what they really needed to do was piggyback on habit loops that were already in place. The marketers needed to position Febreze as something that came at the end of the cleaning ritual, the reward, rather than as a whole new cleaning routine.

The company printed new ads showing open windows and gusts of fresh air. More perfume was added to the Febreze formula, so that instead of merely neutralizing odors, the spray had its own distinct scent. Television commercials were filmed of women, having finished their cleaning routine, using Febreze to spritz freshly made beds and just-laundered clothing. Each ad was designed to appeal to the habit loop: when you see a freshly cleaned room (cue), pull out Febreze (routine) and enjoy a smell that says you’ve done a great job (reward). When you finish making a bed (cue), spritz Febreze (routine) and breathe a sweet, contented sigh (reward). Febreze, the ads implied, was a pleasant treat, not a reminder that your home stinks.

And so Febreze, a product originally conceived as a revolutionary way to destroy odors, became an air freshener used once things are already clean. The Febreze revamp occurred in the summer of 1998. Within two months, sales doubled. A year later, the product brought in $230 million. Since then Febreze has spawned dozens of spinoffs — air fresheners, candles and laundry detergents — that now account for sales of more than $1 billion a year. Eventually, P.& G. began mentioning to customers that, in addition to smelling sweet, Febreze can actually kill bad odors. Today it’s one of the top-selling products in the world.

Andrew Pole was hired by Target to use the same kinds of insights into consumers’ habits to expand Target’s sales. His assignment was to analyze all the cue-routine-reward loops among shoppers and help the company figure out how to exploit them. Much of his department’s work was straightforward: find the customers who have children and send them catalogs that feature toys before Christmas. Look for shoppers who habitually purchase swimsuits in April and send them coupons for sunscreen in July and diet books in December. But Pole’s most important assignment was to identify those unique moments in consumers’ lives when their shopping habits become particularly flexible and the right advertisement or coupon would cause them to begin spending in new ways.

In the 1980s, a team of researchers led by a U.C.L.A. professor named Alan Andreasen undertook a study of peoples’ most mundane purchases, like soap, toothpaste, trash bags and toilet paper. They learned that most shoppers paid almost no attention to how they bought these products, that the purchases occurred habitually, without any complex decision-making. Which meant it was hard for marketers, despite their displays and coupons and product promotions, to persuade shoppers to change.

But when some customers were going through a major life event, like graduating from college or getting a new job or moving to a new town, their shopping habits became flexible in ways that were both predictable and potential gold mines for retailers. The study found that when someone marries, he or she is more likely to start buying a new type of coffee. When a couple move into a new house, they’re more apt to purchase a different kind of cereal. When they divorce, there’s an increased chance they’ll start buying different brands of beer.

Consumers going through major life events often don’t notice, or care, that their shopping habits have shifted, but retailers notice, and they care quite a bit. At those unique moments, Andreasen wrote, customers are “vulnerable to intervention by marketers.” In other words, a precisely timed advertisement, sent to a recent divorcee or new homebuyer, can change someone’s shopping patterns for years.

And among life events, none are more important than the arrival of a baby. At that moment, new parents’ habits are more flexible than at almost any other time in their adult lives. If companies can identify pregnant shoppers, they can earn millions.

The only problem is that identifying pregnant customers is harder than it sounds. Target has a baby-shower registry, and Pole started there, observing how shopping habits changed as a woman approached her due date, which women on the registry had willingly disclosed. He ran test after test, analyzing the data, and before long some useful patterns emerged. Lotions, for example. Lots of people buy lotion, but one of Pole’s colleagues noticed that women on the baby registry were buying larger quantities of unscented lotion around the beginning of their second trimester. Another analyst noted that sometime in the first 20 weeks, pregnant women loaded up on supplements like calcium, magnesium and zinc. Many shoppers purchase soap and cotton balls, but when someone suddenly starts buying lots of scent-free soap and extra-big bags of cotton balls, in addition to hand sanitizers and washcloths, it signals they could be getting close to their delivery date.

As Pole’s computers crawled through the data, he was able to identify about 25 products that, when analyzed together, allowed him to assign each shopper a “pregnancy prediction” score. More important, he could also estimate her due date to within a small window, so Target could send coupons timed to very specific stages of her pregnancy.

One Target employee I spoke to provided a hypothetical example. Take a fictional Target shopper named Jenny Ward, who is 23, lives in Atlanta and in March bought cocoa-butter lotion, a purse large enough to double as a diaper bag, zinc and magnesium supplements and a bright blue rug. There’s, say, an 87 percent chance that she’s pregnant and that her delivery date is sometime in late August. What’s more, because of the data attached to her Guest ID number, Target knows how to trigger Jenny’s habits. They know that if she receives a coupon via e-mail, it will most likely cue her to buy online. They know that if she receives an ad in the mail on Friday, she frequently uses it on a weekend trip to the store. And they know that if they reward her with a printed receipt that entitles her to a free cup of Starbucks coffee, she’ll use it when she comes back again.

In the past, that knowledge had limited value. After all, Jenny purchased only cleaning supplies at Target, and there were only so many psychological buttons the company could push. But now that she is pregnant, everything is up for grabs. In addition to triggering Jenny’s habits to buy more cleaning products, they can also start including offers for an array of products, some more obvious than others, that a woman at her stage of pregnancy might need.

Pole applied his program to every regular female shopper in Target’s national database and soon had a list of tens of thousands of women who were most likely pregnant. If they could entice those women or their husbands to visit Target and buy baby-related products, the company’s cue-routine-reward calculators could kick in and start pushing them to buy groceries, bathing suits, toys and clothing, as well. When Pole shared his list with the marketers, he said, they were ecstatic. Soon, Pole was getting invited to meetings above his paygrade. Eventually his paygrade went up.

At which point someone asked an important question: How are women going to react when they figure out how much Target knows?

“If we send someone a catalog and say, ‘Congratulations on your first child!’ and they’ve never told us they’re pregnant, that’s going to make some people uncomfortable,” Pole told me. “We are very conservative about compliance with all privacy laws. But even if you’re following the law, you can do things where people get queasy.”

About a year after Pole created his pregnancy-prediction model, a man walked into a Target outside Minneapolis and demanded to see the manager. He was clutching coupons that had been sent to his daughter, and he was angry, according to an employee who participated in the conversation.

How to Break the Cookie Habit

Charles Duhigg explains the science of habits.

“My daughter got this in the mail!” he said. “She’s still in high school, and you’re sending her coupons for baby clothes and cribs? Are you trying to encourage her to get pregnant?”

The manager didn’t have any idea what the man was talking about. He looked at the mailer. Sure enough, it was addressed to the man’s daughter and contained advertisements for maternity clothing, nursery furniture and pictures of smiling infants. The manager apologized and then called a few days later to apologize again.

On the phone, though, the father was somewhat abashed. “I had a talk with my daughter,” he said. “It turns out there’s been some activities in my house I haven’t been completely aware of. She’s due in August. I owe you an apology.”

When I approached Target to discuss Pole’s work, its representatives declined to speak with me. “Our mission is to make Target the preferred shopping destination for our guests by delivering outstanding value, continuous innovation and exceptional guest experience,” the company wrote in a statement. “We’ve developed a number of research tools that allow us to gain insights into trends and preferences within different demographic segments of our guest population.” When I sent Target a complete summary of my reporting, the reply was more terse: “Almost all of your statements contain inaccurate information and publishing them would be misleading to the public. We do not intend to address each statement point by point.” The company declined to identify what was inaccurate. They did add, however, that Target “is in compliance with all federal and state laws, including those related to protected health information.”

When I offered to fly to Target’s headquarters to discuss its concerns, a spokeswoman e-mailed that no one would meet me. When I flew out anyway, I was told I was on a list of prohibited visitors. “I’ve been instructed not to give you access and to ask you to leave,” said a very nice security guard named Alex.

Using data to predict a woman’s pregnancy, Target realized soon after Pole perfected his model, could be a public-relations disaster. So the question became: how could they get their advertisements into expectant mothers’ hands without making it appear they were spying on them? How do you take advantage of someone’s habits without letting them know you’re studying their lives?

Before I met Andrew Pole, before I even decided to write a book about the science of habit formation, I had another goal: I wanted to lose weight.

I had got into a bad habit of going to the cafeteria every afternoon and eating a chocolate-chip cookie, which contributed to my gaining a few pounds. Eight, to be precise. I put a Post-it note on my computer reading “NO MORE COOKIES.” But every afternoon, I managed to ignore that note, wander to the cafeteria, buy a cookie and eat it while chatting with colleagues. Tomorrow, I always promised myself, I’ll muster the willpower to resist.

Tomorrow, I ate another cookie.

When I started interviewing experts in habit formation, I concluded each interview by asking what I should do. The first step, they said, was to figure out my habit loop. The routine was simple: every afternoon, I walked to the cafeteria, bought a cookie and ate it while chatting with friends.

Next came some less obvious questions: What was the cue? Hunger? Boredom? Low blood sugar? And what was the reward? The taste of the cookie itself? The temporary distraction from my work? The chance to socialize with colleagues?

Rewards are powerful because they satisfy cravings, but we’re often not conscious of the urges driving our habits in the first place. So one day, when I felt a cookie impulse, I went outside and took a walk instead. The next day, I went to the cafeteria and bought a coffee. The next, I bought an apple and ate it while chatting with friends. You get the idea. I wanted to test different theories regarding what reward I was really craving. Was it hunger? (In which case the apple should have worked.) Was it the desire for a quick burst of energy? (If so, the coffee should suffice.) Or, as turned out to be the answer, was it that after several hours spent focused on work, I wanted to socialize, to make sure I was up to speed on office gossip, and the cookie was just a convenient excuse? When I walked to a colleague’s desk and chatted for a few minutes, it turned out, my cookie urge was gone.

All that was left was identifying the cue.

Deciphering cues is hard, however. Our lives often contain too much information to figure out what is triggering a particular behavior. Do you eat breakfast at a certain time because you’re hungry? Or because the morning news is on? Or because your kids have started eating? Experiments have shown that most cues fit into one of five categories: location, time, emotional state, other people or the immediately preceding action. So to figure out the cue for my cookie habit, I wrote down five things the moment the urge hit:

Where are you? (Sitting at my desk.)

What time is it? (3:36 p.m.)

What’s your emotional state? (Bored.)

Who else is around? (No one.)

What action preceded the urge? (Answered an e-mail.)

The next day I did the same thing. And the next. Pretty soon, the cue was clear: I always felt an urge to snack around 3:30.

Once I figured out all the parts of the loop, it seemed fairly easy to change my habit. But the psychologists and neuroscientists warned me that, for my new behavior to stick, I needed to abide by the same principle that guided Procter & Gamble in selling Febreze: To shift the routine — to socialize, rather than eat a cookie — I needed to piggyback on an existing habit. So now, every day around 3:30, I stand up, look around the newsroom for someone to talk to, spend 10 minutes gossiping, then go back to my desk. The cue and reward have stayed the same. Only the routine has shifted. It doesn’t feel like a decision, any more than the M.I.T. rats made a decision to run through the maze. It’s now a habit. I’ve lost 21 pounds since then (12 of them from changing my cookie ritual).

After Andrew Pole built his pregnancy-prediction model, after he identified thousands of female shoppers who were most likely pregnant, after someone pointed out that some of those women might be a little upset if they received an advertisement making it obvious Target was studying their reproductive status, everyone decided to slow things down.

The marketing department conducted a few tests by choosing a small, random sample of women from Pole’s list and mailing them combinations of advertisements to see how they reacted.

“We have the capacity to send every customer an ad booklet, specifically designed for them, that says, ‘Here’s everything you bought last week and a coupon for it,’ ” one Target executive told me. “We do that for grocery products all the time.” But for pregnant women, Target’s goal was selling them baby items they didn’t even know they needed yet.

“With the pregnancy products, though, we learned that some women react badly,” the executive said. “Then we started mixing in all these ads for things we knew pregnant women would never buy, so the baby ads looked random. We’d put an ad for a lawn mower next to diapers. We’d put a coupon for wineglasses next to infant clothes. That way, it looked like all the products were chosen by chance.

“And we found out that as long as a pregnant woman thinks she hasn’t been spied on, she’ll use the coupons. She just assumes that everyone else on her block got the same mailer for diapers and cribs. As long as we don’t spook her, it works.”

In other words, if Target piggybacked on existing habits — the same cues and rewards they already knew got customers to buy cleaning supplies or socks — then they could insert a new routine: buying baby products, as well. There’s a cue (“Oh, a coupon for something I need!”) a routine (“Buy! Buy! Buy!”) and a reward (“I can take that off my list”). And once the shopper is inside the store, Target will hit her with cues and rewards to entice her to purchase everything she normally buys somewhere else. As long as Target camouflaged how much it knew, as long as the habit felt familiar, the new behavior took hold.

Soon after the new ad campaign began, Target’s Mom and Baby sales exploded. The company doesn’t break out figures for specific divisions, but between 2002 — when Pole was hired — and 2010, Target’s revenues grew from $44 billion to $67 billion. In 2005, the company’s president, Gregg Steinhafel, boasted to a room of investors about the company’s “heightened focus on items and categories that appeal to specific guest segments such as mom and baby.”

Pole was promoted. He has been invited to speak at conferences. “I never expected this would become such a big deal,” he told me the last time we spoke.

A few weeks before this article went to press, I flew to Minneapolis to try and speak to Andrew Pole one last time. I hadn’t talked to him in more than a year. Back when we were still friendly, I mentioned that my wife was seven months pregnant. We shop at Target, I told him, and had given the company our address so we could start receiving coupons in the mail. As my wife’s pregnancy progressed, I noticed a subtle upswing in the number of advertisements for diapers and baby clothes arriving at our house.

Pole didn’t answer my e-mails or phone calls when I visited Minneapolis. I drove to his large home in a nice suburb, but no one answered the door. On my way back to the hotel, I stopped at a Target to pick up some deodorant, then also bought some T-shirts and a fancy hair gel. On a whim, I threw in some pacifiers, to see how the computers would react. Besides, our baby is now 9 months old. You can’t have too many pacifiers.

When I paid, I didn’t receive any sudden deals on diapers or formula, to my slight disappointment. It made sense, though: I was shopping in a city I never previously visited, at 9:45 p.m. on a weeknight, buying a random assortment of items. I was using a corporate credit card, and besides the pacifiers, hadn’t purchased any of the things that a parent needs. It was clear to Target’s computers that I was on a business trip. Pole’s prediction calculator took one look at me, ran the numbers and decided to bide its time. Back home, the offers would eventually come. As Pole told me the last time we spoke: “Just wait. We’ll be sending you coupons for things you want before you even know you want them.”

The Pentagon’s Push to Program Soldiers’ Brains

The military wants future super-soldiers to control robots with their thoughts.

I. Who Could Object?

“Tonight I would like to share with you an idea that I am extremely passionate about,” the young man said. His long black hair was swept back like a rock star’s, or a gangster’s. “Think about this,” he continued. “Throughout all human history, the way that we have expressed our intent, the way we have expressed our goals, the way we have expressed our desires, has been limited by our bodies.” When he inhaled, his rib cage expanded and filled out the fabric of his shirt. Gesturing toward his body, he said, “We are born into this world with this. Whatever nature or luck has given us.“

His speech then took a turn: “Now, we’ve had a lot of interesting tools over the years, but fundamentally the way that we work with those tools is through our bodies.” Then a further turn: “Here’s a situation that I know all of you know very well—your frustration with your smartphones, right? This is another tool, right? And we are still communicating with these tools through our bodies.”

And then it made a leap: “I would claim to you that these tools are not so smart. And maybe one of the reasons why they’re not so smart is because they’re not connected to our brains. Maybe if we could hook those devices into our brains, they could have some idea of what our goals are, what our intent is, and what our frustration is.”

So began “Beyond Bionics,” a talk by Justin C. Sanchez, then an associate professor of biomedical engineering and neuroscience at the University of Miami, and a faculty member of the Miami Project to Cure Paralysis. He was speaking at a tedx conference in Florida in 2012. What lies beyond bionics? Sanchez described his work as trying to “understand the neural code,” which would involve putting “very fine microwire electrodes”—the diameter of a human hair—“into the brain.” When we do that, he said, we would be able to “listen in to the music of the brain” and “listen in to what somebody’s motor intent might be” and get a glimpse of “your goals and your rewards” and then “start to understand how the brain encodes behavior.”

He explained, “With all of this knowledge, what we’re trying to do is build new medical devices, new implantable chips for the body that can be encoded or programmed with all of these different aspects. Now, you may be wondering, what are we going to do with those chips? Well, the first recipients of these kinds of technologies will be the paralyzed. It would make me so happy by the end of my career if I could help get somebody out of their wheelchair.”

Sanchez went on, “The people that we are trying to help should never be imprisoned by their bodies. And today we can design technologies that can help liberate them from that. I’m truly inspired by that. It drives me every day when I wake up and get out of bed. Thank you so much.” He blew a kiss to the audience.

A year later, Justin Sanchez went to work for the Defense Advanced Research Projects Agency, the Pentagon’s R&D department. At darpa, he now oversees all research on the healing and enhancement of the human mind and body. And his ambition involves more than helping get disabled people out of their wheelchair—much more.

DARPA has dreamed for decades of merging human beings and machines. Some years ago, when the prospect of mind-controlled weapons became a public-relations liability for the agency, officials resorted to characteristic ingenuity. They recast the stated purpose of their neurotechnology research to focus ostensibly on the narrow goal of healing injury and curing illness. The work wasn’t about weaponry or warfare, agency officials claimed. It was about therapy and health care. Who could object? But even if this claim were true, such changes would have extensive ethical, social, and metaphysical implications. Within decades, neurotechnology could cause social disruption on a scale that would make smartphones and the internet look like gentle ripples on the pond of history.

Most unsettling, neurotechnology confounds age-old answers to this question: What is a human being?

II. High Risk, High Reward

In his 1958 State of the Union address, President Dwight Eisenhower declared that the United States of America “must be forward-looking in our research and development to anticipate the unimagined weapons of the future.” A few weeks later, his administration created the Advanced Research Projects Agency, a bureaucratically independent body that reported to the secretary of defense. This move had been prompted by the Soviet launch of the Sputnik satellite. The agency’s original remit was to hasten America’s entry into space.

During the next few years, arpa’s mission grew to encompass research into “man-computer symbiosis” and a classified program of experiments in mind control that was code-named Project Pandora. There were bizarre efforts that involved trying to move objects at a distance by means of thought alone. In 1972, with an increment of candor, the word Defense was added to the name, and the agency became darpa. Pursuing its mission, darpa funded researchers who helped invent technologies that changed the nature of battle (stealth aircraft, drones) and shaped daily life for billions (voice-recognition technology, GPS devices). Its best-known creation is the internet.

The agency’s penchant for what it calls “high-risk, high-reward” research ensured that it would also fund a cavalcade of folly. Project Seesaw, a quintessential Cold War boondoggle, envisioned a “particle-beam weapon” that could be deployed in the event of a Soviet attack. The idea was to set off a series of nuclear explosions beneath the Great Lakes, creating a giant underground chamber. Then the lakes would be drained, in a period of 15 minutes, to generate the electricity needed to set off a particle beam. The beam would accelerate through tunnels hundreds of miles long (also carved out by underground nuclear explosions) in order to muster enough force to shoot up into the atmosphere and knock incoming Soviet missiles out of the sky. During the Vietnam War, darpa tried to build a Cybernetic Anthropomorphous Machine, a jungle vehicle that officials called a “mechanical elephant.”

The diverse and sometimes even opposing goals of darpa scientists and their Defense Department overlords merged into a murky, symbiotic research culture—“unencumbered by the typical bureaucratic oversight and uninhibited by the restraints of scientific peer review,” Sharon Weinberger wrote in a recent book, The Imagineers of War. In Weinberger’s account, darpa’s institutional history involves many episodes of introducing a new technology in the context of one appealing application, while hiding other genuine but more troubling motives. At darpa, the left hand knows, and doesn’t know, what the right hand is doing.

The agency is deceptively compact. A mere 220 employees, supported by about 1,000 contractors, report for work each day at darpa’s headquarters, a nondescript glass-and-steel building in Arlington, Virginia, across the street from the practice rink for the Washington Capitals. About 100 of these employees are program managers—scientists and engineers, part of whose job is to oversee about 2,000 outsourcing arrangements with corporations, universities, and government labs. The effective workforce of darpa actually runs into the range of tens of thousands. The budget is officially said to be about $3 billion, and has stood at roughly that level for an implausibly long time—the past 14 years.

The Biological Technologies Office, created in 2014, is the newest of darpa’s six main divisions. This is the office headed by Justin Sanchez. One purpose of the office is to “restore and maintain warfighter abilities” by various means, including many that emphasize neurotechnology—applying engineering principles to the biology of the nervous system. For instance, the Restoring Active Memory program develops neuroprosthetics—tiny electronic components implanted in brain tissue—that aim to alter memory formation so as to counteract traumatic brain injury. Does darpa also run secret biological programs? In the past, the Department of Defense has done such things. It has conducted tests on human subjects that were questionable, unethical, or, many have argued, illegal. The Big Boy protocol, for example, compared radiation exposure of sailors who worked above and below deck on a battleship, never informing the sailors that they were part of an experiment.

Last year I asked Sanchez directly whether any of darpa’s neurotechnology work, specifically, was classified. He broke eye contact and said, “I can’t—We’ll have to get off that topic, because I can’t answer one way or another.” When I framed the question personally—“Are you involved with any classified neuroscience project?”—he looked me in the eye and said, “I’m not doing any classified work on the neurotechnology end.”

If his speech is careful, it is not spare. Sanchez has appeared at public events with some frequency (videos are posted on darpa’s YouTube channel), to articulate joyful streams of good news about darpa’s proven applications—for instance, brain-controlled prosthetic arms for soldiers who have lost limbs. Occasionally he also mentions some of his more distant aspirations. One of them is the ability, via computer, to transfer knowledge and thoughts from one person’s mind to another’s.

III. “We Try to Find Ways to Say Yes”

Medicine and biology were of minor interest to darpa until the 1990s, when biological weapons became a threat to U.S. national security. The agency made a significant investment in biology in 1997, when darpa created the Controlled Biological Systems program. The zoologist Alan S. Rudolph managed this sprawling effort to integrate the built world with the natural world. As he explained it to me, the aim was “to increase, if you will, the baud rate, or the cross-communication, between living and nonliving systems.” He spent his days working through questions such as “Could we unlock the signals in the brain associated with movement in order to allow you to control something outside your body, like a prosthetic leg or an arm, a robot, a smart home—or to send the signal to somebody else and have them receive it?”

Human enhancement became an agency priority. “Soldiers having no physical, physiological, or cognitive limitation will be key to survival and operational dominance in the future,” predicted Michael Goldblatt, who had been the science and technology officer at McDonald’s before joining darpa in 1999. To enlarge humanity’s capacity to “control evolution,” he assembled a portfolio of programs with names that sounded like they’d been taken from video games or sci-fi movies: Metabolic Dominance, Persistence in Combat, Continuous Assisted Performance, Augmented Cognition, Peak Soldier Performance, Brain-Machine Interface.

The programs of this era, as described by Annie Jacobsen in her 2015 book, The Pentagon’s Brain, often shaded into mad-scientist territory. The Continuous Assisted Performance project attempted to create a “24/7 soldier” who could go without sleep for up to a week. (“My measure of success,” one darpa official said of these programs, “is that the International Olympic Committee bans everything we do.”)

Dick Cheney relished this kind of research. In the summer of 2001, an array of “super-soldier” programs was presented to the vice president. His enthusiasm contributed to the latitude that President George W. Bush’s administration gave darpa—at a time when the agency’s foundation was shifting. Academic science gave way to tech-industry “innovation.” Tony Tether, who had spent his career working alternately for Big Tech, defense contractors, and the Pentagon, became darpa’s director. After the 9/11 attacks, the agency announced plans for a surveillance program called Total Information Awareness, whose logo included an all-seeing eye emitting rays of light that scanned the globe. The pushback was intense, and Congress took darpa to task for Orwellian overreach. The head of the program—Admiral John Poindexter, who had been tainted by scandal back in the Reagan years—later resigned, in 2003. The controversy also drew unwanted attention to darpa’s research on super-soldiers and the melding of mind and machine. That research made people nervous, and Alan Rudolph, too, found himself on the way out.

In this time of crisis, darpa invited Geoff Ling, a neurology‑ICU physician and, at the time, an active-duty Army officer, to join the Defense Sciences Office. (Ling went on to work in the Biological Technologies Office when it spun out from Defense Sciences, in 2014.) When Ling was interviewed for his first job at darpa, in 2002, he was preparing for deployment to Afghanistan and thinking about very specific combat needs. One was a “pharmacy on demand” that would eliminate the bulk of powdery fillers from drugs in pill or capsule form and instead would formulate active ingredients for ingestion via a lighter, more compact, dissolving substance—like Listerine breath strips. This eventually became a darpa program. The agency’s brazen sense of possibility buoyed Ling, who recalls with pleasure how colleagues told him, “We try to find ways to say yes, not ways to say no.” With Rudolph gone, Ling picked up the torch.

Ling talks fast. He has a tough-guy voice. The faster he talks, the tougher he sounds, and when I met him, his voice hit top speed as he described a first principle of Defense Sciences. He said he had learned this “particularly” from Alan Rudolph: “Your brain tells your hands what to do. Your hands basically are its tools, okay? And that was a revelation to me.” He continued, “We are tool users—that’s what humans are. A human wants to fly, he builds an airplane and flies. A human wants to have recorded history, and he creates a pen. Everything we do is because we use tools, right? And the ultimate tools are our hands and feet. Our hands allow us to work with the environment to do stuff, and our feet take us where our brain wants to go. The brain is the most important thing.”

Ling connected this idea of the brain’s primacy with his own clinical experience of the battlefield. He asked himself, “How can I liberate mankind from the limitations of the body?” The program for which Ling became best known is called Revolutionizing Prosthetics. Since the Civil War, as Ling has said, the prosthetic arm given to most amputees has been barely more sophisticated than “a hook,” and not without risks: “Try taking care of your morning ablutions with that bad boy, and you’re going to need a proctologist every goddamn day.” With help from darpa colleagues and academic and corporate researchers, Ling and his team built something that was once all but unimaginable: a brain-controlled prosthetic arm.

No invention since the internet has been such a reliable source of good publicity for darpa. Milestones in its development were hailed with wonder. In 2012, 60 Minutes showed a paralyzed woman named Jan Scheuermann feeding herself a bar of chocolate using a robotic arm that she manipulated by means of a brain implant.

​Eddie Guy
Yet darpa’s work to repair damaged bodies was merely a marker on a road to somewhere else. The agency has always had a larger mission, and in a 2015 presentation, one program manager—a Silicon Valley recruit—described that mission: to “free the mind from the limitations of even healthy bodies.” What the agency learns from healing makes way for enhancement. The mission is to make human beings something other than what we are, with powers beyond the ones we’re born with and beyond the ones we can organically attain.

The internal workings of darpa are complicated. The goals and values of its research shift and evolve in the manner of a strange, half-conscious shell game. The line between healing and enhancement blurs. And no one should lose sight of the fact that D is the first letter in darpa’s name. A year and a half after the video of Jan Scheuermann feeding herself chocolate was shown on television, darpa made another video of her, in which her brain-computer interface was connected to an F-35 flight simulator, and she was flying the airplane. darpa later disclosed this at a conference called Future of War.

Geoff Ling’s efforts have been carried on by Justin Sanchez. In 2016, Sanchez appeared at darpa’s “Demo Day” with a man named Johnny Matheny, whom agency officials describe as the first “osseointegrated” upper-limb amputee—the first man with a prosthetic arm attached directly to bone. Matheny demonstrated what was, at the time, darpa’s most advanced prosthetic arm. He told the attendees, “I can sit here and curl a 45-pound dumbbell all day long, till the battery runs dead.” The next day, Gizmodo ran this headline above its report from the event: “darpa’s Mind-Controlled Arm Will Make You Wish You Were a Cyborg.”

Since then, darpa’s work in neurotechnology has avowedly widened in scope, to embrace “the broader aspects of life,” Sanchez told me, “beyond the person in the hospital who is using it to heal.” The logical progression of all this research is the creation of human beings who are ever more perfect, by certain technological standards. New and improved soldiers are necessary and desirable for darpa, but they are just the window-display version of the life that lies ahead.

IV. “Over the Horizon”

Consider memory, Sanchez told me: “Everybody thinks about what it would be like to give memory a boost by 20, 30, 40 percent—pick your favorite number—and how that would be transformative.” He spoke of memory enhancement through neural interface as an alternative form of education. “School in its most fundamental form is a technology that we have developed as a society to help our brains to do more,” he said. “In a different way, neurotechnology uses other tools and techniques to help our brains be the best that they can be.” One technique was described in a 2013 paper, a study involving researchers at Wake Forest University, the University of Southern California, and the University of Kentucky. Researchers performed surgery on 11 rats. Into each rat’s brain, an electronic array—featuring 16 stainless-steel wires—was implanted. After the rats recovered from surgery, they were separated into two groups, and they spent a period of weeks getting educated, though one group was educated more than the other.

The less educated group learned a simple task, involving how to procure a droplet of water. The more educated group learned a complex version of that same task—to procure the water, these rats had to persistently poke levers with their nose despite confounding delays in the delivery of the water droplet. When the more educated group of rats attained mastery of this task, the researchers exported the neural-firing patterns recorded in the rats’ brains—the memory of how to perform the complex task—to a computer.

“What we did then was we took those signals and we gave it to an animal that was stupid,” Geoff Ling said at a darpa event in 2015—meaning that researchers took the neural-firing patterns encoding the memory of how to perform the more complex task, recorded from the brains of the more educated rats, and transferred those patterns into the brains of the less educated rats—“and that stupid animal got it. They were able to execute that full thing.” Ling summarized: “For this rat, we reduced the learning period from eight weeks down to seconds.”

“They could inject memory using the precise neural codes for certain skills,” Sanchez told me. He believes that the Wake Forest experiment amounts to a foundational step toward “memory prosthesis.” This is the stuff of The Matrix. Though many researchers question the findings—cautioning that, really, it can’t be this simple—Sanchez is confident: “If I know the neural codes in one individual, could I give that neural code to another person? I think you could.” Under Sanchez, darpa has funded human experiments at Wake Forest, the University of Southern California, and the University of Pennsylvania, using similar mechanisms in analogous parts of the brain. These experiments did not transfer memory from one person to another, but instead gave individuals a memory “boost.” Implanted electrodes recorded neuronal activity associated with recognizing patterns (at Wake Forest and USC) and memorizing word lists (at Penn) in certain brain circuits. Then electrodes fed back those recordings of neuronal activity into the same circuits as a form of reinforcement. The result, in both cases, was significantly improved memory recall.

Doug Weber, a neural engineer at the University of Pittsburgh who recently finished a four-year term as a darpa program manager, working with Sanchez, is a memory-transfer skeptic. Born in Wisconsin, he has the demeanor of a sitcom dad: not too polished, not too rumpled. “I don’t believe in the infinite limits of technology evolution,” he told me. “I do believe there are going to be some technical challenges which are impossible to achieve.” For instance, when scientists put electrodes in the brain, those devices eventually fail—after a few months or a few years. The most intractable problem is blood leakage. When foreign material is put into the brain, Weber said, “you undergo this process of wounding, bleeding, healing, wounding, bleeding, healing, and whenever blood leaks into the brain compartment, the activity in the cells goes way down, so they become sick, essentially.” More effectively than any fortress, the brain rejects invasion.

Even if the interface problems that limit us now didn’t exist, Weber went on to say, he still would not believe that neuroscientists could enable the memory-prosthesis scenario. Some people like to think about the brain as if it were a computer, Weber explained, “where information goes from A to B to C, like everything is very modular. And certainly there is clear modular organization in the brain. But it’s not nearly as sharp as it is in a computer. All information is everywhere all the time, right? It’s so widely distributed that achieving that level of integration with the brain is far out of reach right now.”

Peripheral nerves, by contrast, conduct signals in a more modular fashion. The biggest, longest peripheral nerve is the vagus. It connects the brain with the heart, the lungs, the digestive tract, and more. Neuroscientists understand the brain’s relationship with the vagus nerve more clearly than they understand the intricacies of memory formation and recall among neurons within the brain. Weber believes that it may be possible to stimulate the vagus nerve in ways that enhance the process of learning—not by transferring experiential memories, but by sharpening the facility for certain skills.

To test this hypothesis, Weber directed the creation of a new program in the Biological Technologies Office, called Targeted Neuroplasticity Training (TNT). Teams of researchers at seven universities are investigating whether vagal-nerve stimulation can enhance learning in three areas: marksmanship, surveillance and reconnaissance, and language. The team at Arizona State has an ethicist on staff whose job, according to Weber, “is to be looking over the horizon to anticipate potential challenges and conflicts that may arise” regarding the ethical dimensions of the program’s technology, “before we let the genie out of the bottle.” At a TNT kickoff meeting, the research teams spent 90 minutes discussing the ethical questions involved in their work—the start of a fraught conversation that will broaden to include many others, and last for a very long time.

DARPA officials refer to the potential consequences of neurotechnology by invoking the acronym elsi, a term of art devised for the Human Genome Project. It stands for “ethical, legal, social implications.” The man who led the discussion on ethics among the research teams was Steven Hyman, a neuroscientist and neuroethicist at MIT and Harvard’s Broad Institute. Hyman is also a former head of the National Institute of Mental Health. When I spoke with him about his work on darpa programs, he noted that one issue needing attention is “cross talk.” A man-machine interface that does not just “read” someone’s brain but also “writes into” someone’s brain would almost certainly create “cross talk between those circuits which we are targeting and the circuits which are engaged in what we might call social and moral emotions,” he said. It is impossible to predict the effects of such cross talk on “the conduct of war” (the example he gave), much less, of course, on ordinary life.

Weber and a darpa spokesperson related some of the questions the researchers asked in their ethics discussion: Who will decide how this technology gets used? Would a superior be able to force subordinates to use it? Will genetic tests be able to determine how responsive someone would be to targeted neuroplasticity training? Would such tests be voluntary or mandatory? Could the results of such tests lead to discrimination in school admissions or employment? What if the technology affects moral or emotional cognition—our ability to tell right from wrong or to control our own behavior?

Recalling the ethics discussion, Weber told me, “The main thing I remember is that we ran out of time.”

V. “You Can Weaponize Anything”

In The Pentagon’s Brain, Annie Jacobsen suggested that darpa’s neurotechnology research, including upper-limb prosthetics and the brain-machine interface, is not what it seems: “It is likely that darpa’s primary goal in advancing prosthetics is to give robots, not men, better arms and hands.” Geoff Ling rejected the gist of her conclusion when I summarized it for him (he hadn’t read the book). He told me, “When we talk about stuff like this, and people are looking for nefarious things, I always say to them, ‘Do you honestly believe that the military that your grandfather served in, your uncle served in, has changed into being Nazis or the Russian army?’ Everything we did in the Revolutionizing Prosthetics program—everything we did—is published. If we were really building an autonomous-weapons system, why would we publish it in the open literature for our adversaries to read? We hid nothing. We hid not a thing. And you know what? That meant that we didn’t just do it for America. We did it for the world.”

I started to say that publishing this research would not prevent its being misused. But the terms use and misuse overlook a bigger issue at the core of any meaningful neurotechnology-ethics discussion. Will an enhanced human being—a human being possessing a neural interface with a computer—still be human, as people have experienced humanity through all of time? Or will such a person be a different sort of creature?

The U.S. government has put limits on darpa’s power to experiment with enhancing human capabilities. Ling says colleagues told him of a “directive”: “Congress was very specific,” he said. “They don’t want us to build a superperson.” This can’t be the announced goal, Congress seems to be saying, but if we get there by accident—well, that’s another story. Ling’s imagination remains at large. He told me, “If I gave you a third eye, and the eye can see in the ultraviolet, that would be incorporated into everything that you do. If I gave you a third ear that could hear at a very high frequency, like a bat or like a snake, then you would incorporate all those senses into your experience and you would use that to your advantage. If you can see at night, you’re better than the person who can’t see at night.”

Enhancing the senses to gain superior advantage—this language suggests weaponry. Such capacities could certainly have military applications, Ling acknowledged—“You can weaponize anything, right?”—before he dismissed the idea and returned to the party line: “No, actually, this has to do with increasing a human’s capability” in a way that he compared to military training and civilian education, and justified in economic terms.

“Let’s say I gave you a third arm,” and then a fourth arm—so, two additional hands, he said. “You would be more capable; you would do more things, right?” And if you could control four hands as seamlessly as you’re controlling your current two hands, he continued, “you would actually be doing double the amount of work that you would normally do. It’s as simple as that. You’re increasing your productivity to do whatever you want to do.” I started to picture his vision—working with four arms, four hands—and asked, “Where does it end?”

“It won’t ever end,” Ling said. “I mean, it will constantly get better and better—” His cellphone rang. He took the call, then resumed where he had left off: “What darpa does is we provide a fundamental tool so that other people can take those tools and do great things with them that we’re not even thinking about.”

Judging by what he said next, however, the number of things that darpa is thinking about far exceeds what it typically talks about in public. “If a brain can control a robot that looks like a hand,” Ling said, “why can’t it control a robot that looks like a snake? Why can’t that brain control a robot that looks like a big mass of Jell-O, able to get around corners and up and down and through things? I mean, somebody will find an application for that. They couldn’t do it now, because they can’t become that glob, right? But in my world, with their brain now having a direct interface with that glob, that glob is the embodiment of them. So now they’re basically the glob, and they can go do everything a glob can do.”

VI. Gold Rush

darpa’s developing capabilities still hover at or near a proof-of-concept stage. But that’s close enough to have drawn investment from some of the world’s richest corporations. In 1990, during the administration of President George H. W. Bush, darpa Director Craig I. Fields lost his job because, according to contemporary news accounts, he intentionally fostered business development with some Silicon Valley companies, and White House officials deemed that inappropriate. Since the administration of the second President Bush, however, such sensitivities have faded.

Over time, darpa has become something of a farm team for Silicon Valley. Regina Dugan, who was appointed darpa director by President Barack Obama, went on to head Google’s Advanced Technology and Projects group, and other former darpa officials went to work for her there. She then led R&D for the analogous group at Facebook, called Building 8. (She has since left Facebook.)

darpa’s neurotechnology research has been affected in recent years by corporate poaching. Doug Weber told me that some darpa researchers have been “scooped up” by companies including Verily, the life-sciences division of Alphabet (the parent company of Google), which, in partnership with the British pharmaceutical conglomerate GlaxoSmithKline, created a company called Galvani Bioelectronics, to bring neuro-modulation devices to market. Galvani calls its business “bioelectric medicine,” which conveys an aura of warmth and trustworthiness. Ted Berger, a University of Southern California biomedical engineer who collaborated with the Wake Forest researchers on their studies of memory transfer in rats, worked as the chief science officer at the neurotechnology company Kernel, which plans to build “advanced neural interfaces to treat disease and dysfunction, illuminate the mechanisms of intelligence, and extend cognition.” Elon Musk has courted darpa researchers to join his company Neuralink, which is said to be developing an interface known as “neural lace.” Facebook’s Building 8 is working on a neural interface too. In 2017, Regina Dugan said that 60 engineers were at work on a system with the goal of allowing users to type 100 words a minute “directly from your brain.” Geoff Ling is on Building 8’s advisory board.

Talking with Justin Sanchez, I speculated that if he realizes his ambitions, he could change daily life in even more fundamental and lasting ways than Facebook’s Mark Zuckerberg and Twitter’s Jack Dorsey have. Sanchez blushes easily, and he breaks eye contact when he is uncomfortable, but he did not look away when he heard his name mentioned in such company. Remembering a remark that he had once made about his hope for neurotechnology’s wide adoption, but with “appropriate checks to make sure that it’s done in the right way,” I asked him to talk about what the right way might look like. Did any member of Congress strike him as having good ideas about legal or regulatory structures that might shape an emerging neural-interface industry? He demurred (“darpa’s mission isn’t to define or even direct those things”) and suggested that, in reality, market forces would do more to shape the evolution of neurotechnology than laws or regulations or deliberate policy choices. What will happen, he said, is that scientists at universities will sell their discoveries or create start-ups. The marketplace will take it from there: “As they develop their companies, and as they develop their products, they’re going to be subject to convincing people that whatever they’re developing makes sense, that it helps people to be a better version of themselves. And that process—that day-to-day development—will ultimately guide where these technologies go. I mean, I think that’s the frank reality of how it ultimately will unfold.”

He seemed entirely untroubled by what may be the most troubling aspect of darpa’s work: not that it discovers what it discovers, but that the world has, so far, always been ready to buy it.

Google’s DeepMind AI can accurately detect 50 types of eye disease just by looking at scans

Mustafa Suleyman 1831_preview (1)DeepMind cofounder Mustafa Suleyman.DeepMind
  • Google’s artificial intelligence company DeepMind has published „really significant“ research showing its algorithm can identify around 50 eye diseases by looking at retinal eye scans.
  • DeepMind said its AI was as good as expert clinicians, and that it could help prevent people from losing their sight.
  • DeepMind has been criticised for its practices around medical data, but cofounder Mustafa Suleyman said all the information in this research project was anonymised.
  • The company plans to hand the technology over for free to NHS hospitals for five years, provided it passes the next phase of research.

Google’s artificial intelligence company, DeepMind, has developed an AI which can successfully detect more than 50 types of eye disease just by looking at 3D retinal scans.

DeepMind published on Monday the results of joint research with Moorfields Eye Hospital, a renowned centre for treating eye conditions in London, in Nature Medicine.

The company said its AI was as accurate as expert clinicians when it came to detecting diseases, such as diabetic eye disease and macular degeneration. It could also recommend the best course of action for patients and suggest which needed urgent care.

What is especially significant about the research, according to DeepMind cofounder Mustafa Suleyman, is that the AI has a level of „explainability“ that could boost doctors‘ trust in its recommendations.

„It’s possible for the clinician to interpret what the algorithm is thinking,“ he told Business Insider. „[They can] look at the underlying segmentation.“

In other words, the AI looks less like a mysterious black box that’s spitting out results. It labels pixels on the eye scan that corresponds to signs of a particular disease, Suleyman explained, and can calculate its confidence in its own findings with a percentage score. „That’s really significant,“ he said.

Suleyman described the findings as a „research breakthrough“ and said the next step was to prove the AI works in a clinical setting. That, he said, would take a number of years. Once DeepMind is in a position to deploy its AI across NHS hospitals in the UK, it will provide the service for free for five years.

Patients are at risk of losing their sight because doctors can’t look at their eye scans in time

British eye specialists have been warning for years that patients are at risk of losing their sight because the NHS is overstretched, and because the UK has an ageing population.

Part of the reason DeepMind and Moorfields took up the research project was because clinicians are „overwhelmed“ by the demand for eye scans, Suleyman said.

„If you have a sight-threatening disease, you want treatment as soon as possible,“ he explained. „And unlike in A&E, where a staff nurse will talk to you and make an evaluation of how serious your condition is, then use that evaluation to decide how quickly you are seen. When an [eye] scan is submitted, there isn’t a triage of your scan according to its severity.“

OCT scanA patient having an OCT scan.DeepMind

Putting eye scans through the AI could speed the entire process up.

„In the future, I could envisage a person going into their local high street optician, and have an OCT scan done and this algorithm would identify those patients with sight-threatening disease at the very early stage of the condition,“ said Dr Pearse Keane, consultant ophthalmologist at Moorfields Eye Hospital.

DeepMind’s AI was trained on a database of almost 15,000 eye scans, stripped of any identifying information. DeepMind worked with clinicians to label areas of disease, then ran those labelled images through its system. Suleyman said the two-and-a-half project required „huge investment“ from DeepMind and involved 25 staffers, as well as the researchers from Moorfields.

People are still worried about a Google-linked company having access to medical data

Google acquired DeepMind in 2014 for £400 million ($509 million), and the British AI company is probably most famous for AlphaGo, its algorithm that beat the world champion at the strategy game Go.

While DeepMind has remained UK-based and independent from Google, the relationship has attracted scrutiny. The main question is whether Google, a private US company, should have access to the sensitive medical data required for DeepMind’s health arm.

DeepMind was criticised in 2016 for failing to disclose its access to historical medical data during a project with Royal Free Hospital. Suleyman said the eye scans processed by DeepMind were „completely anonymised.“

„You can’t identify whose scans it was. We’re in quite a different regime, this is very much research, and we’re a number of years from being able to deploy in practice,“ he said.

Suleyman added: „How this has the potential to have transform the NHS is very clear. We’ve been very conscious that this will be a model that’s published, and available to others to implement.

„The labelled dataset is available to other researchers. So this is very much an open and collaborative relationship between equals that we’ve worked hard to foster. I’m proud of that work.“

Microsoft wants regulation of facial recognition technology to limit ‚abuse‘

Facial recognition put to the test
Facial recognition put to the test

Microsoft has helped innovate facial recognition software. Now it’s urging the US government to enact regulation to control the use of the technology.

In a blog post, Microsoft (MSFT)President Brad Smith said new laws are necessary given the technology’s „broad societal ramifications and potential for abuse.“

He urged lawmakers to form „a government initiative to regulate the proper use of facial recognition technology, informed first by a bipartisan and expert commission.“

Facial recognition — a computer’s ability to identify or verify people’s faces from a photo or through a camera — has been developing rapidly. Apple (AAPL), Google (GOOG), Amazon and Microsoft are among the big tech companies developing and selling such systems. The technology is being used across a range of industries, from private businesses like hotels and casinos, to social media and law enforcement.

Supporters say facial recognition software improves safety for companies and customers and can help police track police down criminals or find missing children. Civil rights groups warn it can infringe on privacy and allow for illegal surveillance and monitoring. There is also room for error, they argue, since the still-emerging technology can result in false identifications.

The accuracy of facial recognition technologies varies, with women and people of color being identified with less accuracy, according to MIT research.

„Facial recognition raises a critical question: what role do we want this type of technology to play in everyday society?“ Smith wrote on Friday.

Smith’s call for a regulatory framework to control the technology comes as tech companies face criticism over how they’ve handled and shared customer data, as well as their cooperation with government agencies.

Last month, Microsoft was scrutinized for its working relationship with US Immigration and Customs Enforcement. ICE had been enforcing the Trump administration’s „zero tolerance“ immigration policy that separated children from their parents when they crossed the US border illegally. The administration has since abandoned the policy.

Microsoft urges Trump administration to change its policy separating families at border

Microsoft wrote a blog post in January about ICE’s use of its cloud technology Azure, saying it could help it „accelerate facial recognition and identification.“

After questions arose about whether Microsoft’s technology had been used by ICE agents to carry out the controversial border separations, the company released a statement calling the policy „cruel“ and „abusive.“

In his post, Smith reiterated Microsoft’s opposition to the policy and said he had confirmed its contract with ICE does not include facial recognition technology.

Amazon(AMZN) has also come under fire from its own shareholders and civil rights groups over local police forces using its face identifying software Rekognition, which can identify up to 100 people in a single photo.

Some Amazon shareholders coauthored a letter pressuring Amazon to stop selling the technology to the government, saying it was aiding in mass surveillance and posed a threat to privacy rights.

Amazon asked to stop selling facial recognition technology to police

And Facebook (FB) is embroiled in a class-action lawsuit that alleges the social media giant used facial recognition on photos without user permission. Its facial recognition tool scans your photos and suggests you tag friends.

Neither Amazon nor Facebook immediately responded to a request for comment about Smith’s call for new regulations on face ID technology.

Smith said companies have a responsibility to police their own innovations, control how they are deployed and ensure that they are used in a „a manner consistent with broadly held societal values.“

„It may seem unusual for a company to ask for government regulation of its products, but there are many markets where thoughtful regulation contributes to a healthier dynamic for consumers and producers alike,“ he said.

June 2018 Tech News & Trends to Watch

1. Companies Worldwide Strive for GDPR Compliance

By now, everyone with an email address has seen a slew of emails announcing privacy policy updates. You have Europe’s GDPR legislation to thank for your overcrowded inbox. GDPR creates rules around how much data companies are allowed to collect, how they’re able to use that data, and how clear they have to be with consumers about it all.

Companies around the world are scrambling to get their business and its practices into compliance – a significant task for many of them. While technically, the deadline to get everything in order passed on May 25, for many companies the process will continue well into June and possibly beyond. Some companies are even shutting down in Europe for good, or for as long as it takes them to get in compliance.

Even with the deadline behind us, the GDPR continues to be a top story for the tech world and may remain so for some time to come.

 

2. Amazon Provides Facial Recognition Tech to Law Enforcement

Amazon can’t seem to go a whole month without showing up in a tech news roundup. This month it’s for a controversial story: selling use of Rekognition, their facial recognition software, to law enforcement agencies on the cheap.

Civil rights groups have called for the company to stop allowing law enforcement access to the tech out of concerns that increased government surveillance can pose a threat to vulnerable communities in the country. In spite of the public criticism, Amazon hasn’t backed off on providing the tech to authorities, at least as of this time.

 

3. Apple Looks Into Self-Driving Employee Shuttles

Of the many problems facing our world, the frustrating work commute is one that many of the brightest minds in tech deal with just like the rest of us. Which makes it a problem the biggest tech companies have a strong incentive to try to solve.

Apple is one of many companies that’s invested in developing self-driving cars as a possible solution, but while that goal is still (probably) years away, they’ve narrowed their focus to teaming up with VW to create self-driving shuttles just for their employees.  Even that project is moving slower than the company had hoped, but they’re aiming to have some shuttles ready by the end of the year.

 

4. Court Weighs in on President’s Tendency to Block Critics on Twitter

Three years ago no one would have imagined that Twitter would be a president’s go-to source for making announcements, but today it’s used to that effect more frequently than official press conferences or briefings.

In a court battle that may sound surreal to many of us, a judge just found that the president can no longer legally block other users on Twitter.  The court asserted that blocking users on a public forum like Twitter amounts to a violation of their First Amendment rights. The judgment does still allow for the president and other public officials to mute users they don’t agree with, though.

 

5. YouTube Launches Music Streaming Service

YouTube joined the ranks of Spotify, Pandora, and Amazon this past month with their own streaming music service. Consumers can use a free version of the service that includes ads, or can pay $9.99 for the ad-free version.

With so many similar services already on the market, people weren’t exactly clamoring for another music streaming option. But since YouTube is likely to remain the reigning source for videos, it doesn’t necessarily need to unseat Spotify to still be okay. And with access to Google’s extensive user data, it may be able to provide more useful recommendations than its main competitors in the space, which is one way the service could differentiate itself.

 

6. Facebook Institutes Political Ad Rules

Facebook hasn’t yet left behind the controversies of the last election. The company is still working to proactively respond to criticism of its role in the spread of political propaganda many believe influenced election results. One of the solutions they’re trying is a new set of rules for any political ads run on the platform.

Any campaign that intends to run Facebook ads is now required to verify their identity with a card Facebook mails to their address that has a verification code. While Facebook has been promoting these new rules for a few weeks to politicians active on the platform, some felt blindsided when they realized, right before their primaries no less, that they could no longer place ads without waiting 12 to 15 days for a verification code to come in the mail. Politicians in this position blame the company for making a change that could affect their chances in the upcoming election.

Even in their efforts to avoid swaying elections, Facebook has found themselves criticized for doing just that. They’re probably feeling at this point like they just can’t win.

 

7. Another Big Month for Tech IPOs

This year has seen one tech IPO after another and this month is no different. Chinese smartphone company Xiaomi has a particularly large IPO in the works. The company seeks to join the Hong Kong stock exchange on June 7 with an initial public offering that experts anticipate could reach $10 billion.

The online lending platform Greensky started trading on the New York Stock Exchange on May 23 and sold 38 million shares in its first day, 4 million more than expected. This month continues 2018’s trend of tech companies going public, largely to great success.

 

8. StumbleUpon Shuts Down

In the internet’s ongoing evolution, there will always be tech companies that win and those that fall by the wayside. StumbleUpon, a content discovery platform that had its heyday in the early aughts, is officially shutting down on June 30.

Since its 2002 launch, the service has helped over 40 million users “stumble upon” 60 billion new websites and pieces of content. The company behind StumbleUpon plans to create a new platform that serves a similar purpose that may be more useful to former StumbleUpon users called Mix.

 

9. Uber and Lyft Invest in Driver Benefits

In spite of their ongoing success, the popular ridesharing platforms Uber and Lyft have faced their share of criticism since they came onto the scene. One of the common complaints critics have made is that the companies don’t provide proper benefits to their drivers. And in fact, the companies have fought to keep drivers classified legally as contractors so they’re off the hook for covering the cost of employee taxes and benefits.

Recently both companies have taken steps to make driving for them a little more attractive. Uber has begun offering Partner Protection to its drivers in Europe, which includes health insurance, sick pay, and parental leave ­ ­– so far nothing similar in the U.S. though. For its part, Lyft is investing $100 million in building driver support centers where their drivers can stop to get discounted car maintenance, tax help, and customer support help in person from Lyft staff. It’s not the same as getting full employee benefits (in the U.S. at least), but it’s something.

The Evolution of AI

Artificial Intelligence — The Revolution Hasn’t Happened Yet

Artificial Intelligence (AI) is the mantra of the current era. The phrase is intoned by technologists, academicians, journalists and venture capitalists alike. As with many phrases that cross over from technical academic fields into general circulation, there is significant misunderstanding accompanying the use of the phrase. But this is not the classical case of the public not understanding the scientists — here the scientists are often as befuddled as the public. The idea that our era is somehow seeing the emergence of an intelligence in silicon that rivals our own entertains all of us — enthralling us and frightening us in equal measure. And, unfortunately, it distracts us.

There is a different narrative that one can tell about the current era. Consider the following story, which involves humans, computers, data and life-or-death decisions, but where the focus is something other than intelligence-in-silicon fantasies. When my spouse was pregnant 14 years ago, we had an ultrasound. There was a geneticist in the room, and she pointed out some white spots around the heart of the fetus. “Those are markers for Down syndrome,” she noted, “and your risk has now gone up to 1 in 20.” She further let us know that we could learn whether the fetus in fact had the genetic modification underlying Down syndrome via an amniocentesis. But amniocentesis was risky — the risk of killing the fetus during the procedure was roughly 1 in 300. Being a statistician, I determined to find out where these numbers were coming from. To cut a long story short, I discovered that a statistical analysis had been done a decade previously in the UK, where these white spots, which reflect calcium buildup, were indeed established as a predictor of Down syndrome. But I also noticed that the imaging machine used in our test had a few hundred more pixels per square inch than the machine used in the UK study. I went back to tell the geneticist that I believed that the white spots were likely false positives — that they were literally “white noise.” She said “Ah, that explains why we started seeing an uptick in Down syndrome diagnoses a few years ago; it’s when the new machine arrived.”

We didn’t do the amniocentesis, and a healthy girl was born a few months later. But the episode troubled me, particularly after a back-of-the-envelope calculation convinced me that many thousands of people had gotten that diagnosis that same day worldwide, that many of them had opted for amniocentesis, and that a number of babies had died needlessly. And this happened day after day until it somehow got fixed. The problem that this episode revealed wasn’t about my individual medical care; it was about a medical system that measured variables and outcomes in various places and times, conducted statistical analyses, and made use of the results in other places and times. The problem had to do not just with data analysis per se, but with what database researchers call “provenance” — broadly, where did data arise, what inferences were drawn from the data, and how relevant are those inferences to the present situation? While a trained human might be able to work all of this out on a case-by-case basis, the issue was that of designing a planetary-scale medical system that could do this without the need for such detailed human oversight.

I’m also a computer scientist, and it occurred to me that the principles needed to build planetary-scale inference-and-decision-making systems of this kind, blending computer science with statistics, and taking into account human utilities, were nowhere to be found in my education. And it occurred to me that the development of such principles — which will be needed not only in the medical domain but also in domains such as commerce, transportation and education — were at least as important as those of building AI systems that can dazzle us with their game-playing or sensorimotor skills.

Whether or not we come to understand “intelligence” any time soon, we do have a major challenge on our hands in bringing together computers and humans in ways that enhance human life. While this challenge is viewed by some as subservient to the creation of “artificial intelligence,” it can also be viewed more prosaically — but with no less reverence — as the creation of a new branch of engineering. Much like civil engineering and chemical engineering in decades past, this new discipline aims to corral the power of a few key ideas, bringing new resources and capabilities to people, and doing so safely. Whereas civil engineering and chemical engineering were built on physics and chemistry, this new engineering discipline will be built on ideas that the preceding century gave substance to — ideas such as “information,” “algorithm,” “data,” “uncertainty,” “computing,” “inference,” and “optimization.” Moreover, since much of the focus of the new discipline will be on data from and about humans, its development will require perspectives from the social sciences and humanities.

While the building blocks have begun to emerge, the principles for putting these blocks together have not yet emerged, and so the blocks are currently being put together in ad-hoc ways.

Thus, just as humans built buildings and bridges before there was civil engineering, humans are proceeding with the building of societal-scale, inference-and-decision-making systems that involve machines, humans and the environment. Just as early buildings and bridges sometimes fell to the ground — in unforeseen ways and with tragic consequences — many of our early societal-scale inference-and-decision-making systems are already exposing serious conceptual flaws.

And, unfortunately, we are not very good at anticipating what the next emerging serious flaw will be. What we’re missing is an engineering discipline with its principles of analysis and design.

The current public dialog about these issues too often uses “AI” as an intellectual wildcard, one that makes it difficult to reason about the scope and consequences of emerging technology. Let us begin by considering more carefully what “AI” has been used to refer to, both recently and historically.

Most of what is being called “AI” today, particularly in the public sphere, is what has been called “Machine Learning” (ML) for the past several decades. ML is an algorithmic field that blends ideas from statistics, computer science and many other disciplines (see below) to design algorithms that process data, make predictions and help make decisions. In terms of impact on the real world, ML is the real thing, and not just recently. Indeed, that ML would grow into massive industrial relevance was already clear in the early 1990s, and by the turn of the century forward-looking companies such as Amazon were already using ML throughout their business, solving mission-critical back-end problems in fraud detection and supply-chain prediction, and building innovative consumer-facing services such as recommendation systems. As datasets and computing resources grew rapidly over the ensuing two decades, it became clear that ML would soon power not only Amazon but essentially any company in which decisions could be tied to large-scale data. New business models would emerge. The phrase “Data Science” began to be used to refer to this phenomenon, reflecting the need of ML algorithms experts to partner with database and distributed-systems experts to build scalable, robust ML systems, and reflecting the larger social and environmental scope of the resulting systems.

This confluence of ideas and technology trends has been rebranded as “AI” over the past few years. This rebranding is worthy of some scrutiny.

Historically, the phrase “AI” was coined in the late 1950’s to refer to the heady aspiration of realizing in software and hardware an entity possessing human-level intelligence. We will use the phrase “human-imitative AI” to refer to this aspiration, emphasizing the notion that the artificially intelligent entity should seem to be one of us, if not physically at least mentally (whatever that might mean). This was largely an academic enterprise. While related academic fields such as operations research, statistics, pattern recognition, information theory and control theory already existed, and were often inspired by human intelligence (and animal intelligence), these fields were arguably focused on “low-level” signals and decisions. The ability of, say, a squirrel to perceive the three-dimensional structure of the forest it lives in, and to leap among its branches, was inspirational to these fields. “AI” was meant to focus on something different — the “high-level” or “cognitive” capability of humans to “reason” and to “think.” Sixty years later, however, high-level reasoning and thought remain elusive. The developments which are now being called “AI” arose mostly in the engineering fields associated with low-level pattern recognition and movement control, and in the field of statistics — the discipline focused on finding patterns in data and on making well-founded predictions, tests of hypotheses and decisions.

Indeed, the famous “backpropagation” algorithm that was rediscovered by David Rumelhart in the early 1980s, and which is now viewed as being at the core of the so-called “AI revolution,” first arose in the field of control theory in the 1950s and 1960s. One of its early applications was to optimize the thrusts of the Apollo spaceships as they headed towards the moon.

Since the 1960s much progress has been made, but it has arguably not come about from the pursuit of human-imitative AI. Rather, as in the case of the Apollo spaceships, these ideas have often been hidden behind the scenes, and have been the handiwork of researchers focused on specific engineering challenges. Although not visible to the general public, research and systems-building in areas such as document retrieval, text classification, fraud detection, recommendation systems, personalized search, social network analysis, planning, diagnostics and A/B testing have been a major success — these are the advances that have powered companies such as Google, Netflix, Facebook and Amazon.

One could simply agree to refer to all of this as “AI,” and indeed that is what appears to have happened. Such labeling may come as a surprise to optimization or statistics researchers, who wake up to find themselves suddenly referred to as “AI researchers.” But labeling of researchers aside, the bigger problem is that the use of this single, ill-defined acronym prevents a clear understanding of the range of intellectual and commercial issues at play.

The past two decades have seen major progress — in industry and academia — in a complementary aspiration to human-imitative AI that is often referred to as “Intelligence Augmentation” (IA). Here computation and data are used to create services that augment human intelligence and creativity. A search engine can be viewed as an example of IA (it augments human memory and factual knowledge), as can natural language translation (it augments the ability of a human to communicate). Computing-based generation of sounds and images serves as a palette and creativity enhancer for artists. While services of this kind could conceivably involve high-level reasoning and thought, currently they don’t — they mostly perform various kinds of string-matching and numerical operations that capture patterns that humans can make use of.

Hoping that the reader will tolerate one last acronym, let us conceive broadly of a discipline of “Intelligent Infrastructure” (II), whereby a web of computation, data and physical entities exists that makes human environments more supportive, interesting and safe. Such infrastructure is beginning to make its appearance in domains such as transportation, medicine, commerce and finance, with vast implications for individual humans and societies. This emergence sometimes arises in conversations about an “Internet of Things,” but that effort generally refers to the mere problem of getting “things” onto the Internet — not to the far grander set of challenges associated with these “things” capable of analyzing those data streams to discover facts about the world, and interacting with humans and other “things” at a far higher level of abstraction than mere bits.

For example, returning to my personal anecdote, we might imagine living our lives in a “societal-scale medical system” that sets up data flows, and data-analysis flows, between doctors and devices positioned in and around human bodies, thereby able to aid human intelligence in making diagnoses and providing care. The system would incorporate information from cells in the body, DNA, blood tests, environment, population genetics and the vast scientific literature on drugs and treatments. It would not just focus on a single patient and a doctor, but on relationships among all humans — just as current medical testing allows experiments done on one set of humans (or animals) to be brought to bear in the care of other humans. It would help maintain notions of relevance, provenance and reliability, in the way that the current banking system focuses on such challenges in the domain of finance and payment. And, while one can foresee many problems arising in such a system — involving privacy issues, liability issues, security issues, etc — these problems should properly be viewed as challenges, not show-stoppers.

We now come to a critical issue: Is working on classical human-imitative AI the best or only way to focus on these larger challenges? Some of the most heralded recent success stories of ML have in fact been in areas associated with human-imitative AI — areas such as computer vision, speech recognition, game-playing and robotics. So perhaps we should simply await further progress in domains such as these. There are two points to make here. First, although one would not know it from reading the newspapers, success in human-imitative AI has in fact been limited — we are very far from realizing human-imitative AI aspirations. Unfortunately the thrill (and fear) of making even limited progress on human-imitative AI gives rise to levels of over-exuberance and media attention that is not present in other areas of engineering.

Second, and more importantly, success in these domains is neither sufficient nor necessary to solve important IA and II problems. On the sufficiency side, consider self-driving cars. For such technology to be realized, a range of engineering problems will need to be solved that may have little relationship to human competencies (or human lack-of-competencies). The overall transportation system (an II system) will likely more closely resemble the current air-traffic control system than the current collection of loosely-coupled, forward-facing, inattentive human drivers. It will be vastly more complex than the current air-traffic control system, specifically in its use of massive amounts of data and adaptive statistical modeling to inform fine-grained decisions. It is those challenges that need to be in the forefront, and in such an effort a focus on human-imitative AI may be a distraction.

As for the necessity argument, it is sometimes argued that the human-imitative AI aspiration subsumes IA and II aspirations, because a human-imitative AI system would not only be able to solve the classical problems of AI (as embodied, e.g., in the Turing test), but it would also be our best bet for solving IA and II problems. Such an argument has little historical precedent. Did civil engineering develop by envisaging the creation of an artificial carpenter or bricklayer? Should chemical engineering have been framed in terms of creating an artificial chemist? Even more polemically: if our goal was to build chemical factories, should we have first created an artificial chemist who would have then worked out how to build a chemical factory?

A related argument is that human intelligence is the only kind of intelligence that we know, and that we should aim to mimic it as a first step. But humans are in fact not very good at some kinds of reasoning — we have our lapses, biases and limitations. Moreover, critically, we did not evolve to perform the kinds of large-scale decision-making that modern II systems must face, nor to cope with the kinds of uncertainty that arise in II contexts. One could argue
that an AI system would not only imitate human intelligence, but also “correct” it, and would also scale to arbitrarily large problems. But we are now in the realm of science fiction — such speculative arguments, while entertaining in the setting of fiction, should not be our principal strategy going forward in the face of the critical IA and II problems that are beginning to emerge. We need to solve IA and II problems on their own merits, not as a mere corollary to a human-imitative AI agenda.

It is not hard to pinpoint algorithmic and infrastructure challenges in II systems that are not central themes in human-imitative AI research. II systems require the ability to manage distributed repositories of knowledge that are rapidly changing and are likely to be globally incoherent. Such systems must cope with cloud-edge interactions in making timely, distributed decisions and they must deal with long-tail phenomena whereby there is lots of data on some individuals and little data on most individuals. They must address the difficulties of sharing data across administrative and competitive boundaries. Finally, and of particular importance, II systems must bring economic ideas such as incentives and pricing into the realm of the statistical and computational infrastructures that link humans to each other and to valued goods. Such II systems can be viewed as not merely providing a service, but as creating markets. There are domains such as music, literature and journalism that are crying out for the emergence of such markets, where data analysis links producers and consumers. And this must all be done within the context of evolving societal, ethical and legal norms.

Of course, classical human-imitative AI problems remain of great interest as well. However, the current focus on doing AI research via the gathering of data, the deployment of “deep learning” infrastructure, and the demonstration of systems that mimic certain narrowly-defined human skills — with little in the way of emerging explanatory principles — tends to deflect attention from major open problems in classical AI. These problems include the need to bring meaning and reasoning into systems that perform natural language processing, the need to infer and represent causality, the need to develop computationally-tractable representations of uncertainty and the need to develop systems that formulate and pursue long-term goals. These are classical goals in human-imitative AI, but in the current hubbub over the “AI revolution,” it is easy to forget that they are not yet solved.

IA will also remain quite essential, because for the foreseeable future, computers will not be able to match humans in their ability to reason abstractly about real-world situations. We will need well-thought-out interactions of humans and computers to solve our most pressing problems. And we will want computers to trigger new levels of human creativity, not replace human creativity (whatever that might mean).

It was John McCarthy (while a professor at Dartmouth, and soon to take a
position at MIT) who coined the term “AI,” apparently to distinguish his
budding research agenda from that of Norbert Wiener (then an older professor at MIT). Wiener had coined “cybernetics” to refer to his own vision of intelligent systems — a vision that was closely tied to operations research, statistics, pattern recognition, information theory and control theory. McCarthy, on the other hand, emphasized the ties to logic. In an interesting reversal, it is Wiener’s intellectual agenda that has come to dominate in the current era, under the banner of McCarthy’s terminology. (This state of affairs is surely, however, only temporary; the pendulum swings more in AI than
in most fields.)

But we need to move beyond the particular historical perspectives of McCarthy and Wiener.

We need to realize that the current public dialog on AI — which focuses on a narrow subset of industry and a narrow subset of academia — risks blinding us to the challenges and opportunities that are presented by the full scope of AI, IA and II.

This scope is less about the realization of science-fiction dreams or nightmares of super-human machines, and more about the need for humans to understand and shape technology as it becomes ever more present and influential in their daily lives. Moreover, in this understanding and shaping there is a need for a diverse set of voices from all walks of life, not merely a dialog among the technologically attuned. Focusing narrowly on human-imitative AI prevents an appropriately wide range of voices from being heard.

While industry will continue to drive many developments, academia will also continue to play an essential role, not only in providing some of the most innovative technical ideas, but also in bringing researchers from the computational and statistical disciplines together with researchers from other
disciplines whose contributions and perspectives are sorely needed — notably
the social sciences, the cognitive sciences and the humanities.

On the other hand, while the humanities and the sciences are essential as we go forward, we should also not pretend that we are talking about something other than an engineering effort of unprecedented scale and scope — society is aiming to build new kinds of artifacts. These artifacts should be built to work as claimed. We do not want to build systems that help us with medical treatments, transportation options and commercial opportunities to find out after the fact that these systems don’t really work — that they make errors that take their toll in terms of human lives and happiness. In this regard, as I have emphasized, there is an engineering discipline yet to emerge for the data-focused and learning-focused fields. As exciting as these latter fields appear to be, they cannot yet be viewed as constituting an engineering discipline.

Moreover, we should embrace the fact that what we are witnessing is the creation of a new branch of engineering. The term “engineering” is often
invoked in a narrow sense — in academia and beyond — with overtones of cold, affectless machinery, and negative connotations of loss of control by humans. But an engineering discipline can be what we want it to be.

In the current era, we have a real opportunity to conceive of something historically new — a human-centric engineering discipline.

I will resist giving this emerging discipline a name, but if the acronym “AI” continues to be used as placeholder nomenclature going forward, let’s be aware of the very real limitations of this placeholder. Let’s broaden our scope, tone down the hype and recognize the serious challenges ahead.
