EARLIER this week, I spotted, among the job listings in the newspaper Reforma, an ad from a restaurant in Mexico City looking to hire dishwashers. The requirement: a secondary school diploma.

Years ago, school was not for everyone. Classrooms were places for discipline, study. Teachers were respected figures. Parents actually gave them permission to punish their children by slapping them or tugging their ears. But at least in those days, schools aimed to offer a more dignified life.

During a strike in 2008 in Oaxaca, I remember walking through the temporary campground in search of a teacher reading a book. Among tens of thousands, I found not one. I did find people listening to disco-decibel music, watching television, playing cards or dominoes, vegetating. I saw some gossip magazines, too.

Although algorithms are growing ever more powerful, fast and precise, the computers themselves are literal-minded, and context and nuance often elude them. Capable as these machines are, they are not always up to deciphering the ambiguity of human language and the mystery of reasoning.

And so, while programming experts still write the step-by-step instructions of computer code, additional people are needed to make more subtle contributions as the work the computers do has become more involved. People evaluate, edit or correct an algorithm’s work. Or they assemble online databases of knowledge and check and verify them — creating, essentially, a crib sheet the computer can call on for a quick answer. Humans can interpret and tweak information in ways that are understandable to both computers and other humans.

Even at Google, where algorithms and engineers reign supreme in the company’s business and culture, the human contribution to search results is increasing. Google uses human helpers in two ways. Several months ago, it began presenting summaries of information on the right side of a search page when a user typed in the name of a well-known person or place, like “Barack Obama” or “New York City.” These summaries draw from databases of knowledge like Wikipedia, the C.I.A. World Factbook and Freebase, whose parent company, Metaweb, Google acquired in 2010. These databases are edited by humans.

academic researchers and scientists at companies like Microsoft, I.B.M. and Hewlett-Packard have been working to develop quantum computers.

Lockheed Martin — which bought an early version of such a computer from the Canadian company D-Wave Systems two years ago — is confident enough in the technology to upgrade it to commercial scale, becoming the first company to use quantum computing as part of its business.

if it performs as Lockheed and D-Wave expect, the design could be used to supercharge even the most powerful systems, solving some science and business problems millions of times faster

Psychologists Shannon Rauch and Kimberley Schanz published their work in the journal Computers in Human Behavior. They sampled 623 Internet users (all white, 70 percent students), asking them to indicate the frequency of their Facebook usage. The group then read one of three versions of a Facebook Notes page they were told was written by a 26-year-old named Jack Brown. "Jack" was white and male. The first version of Jack's message contained what the researchers call a "superiority message": It "contrasted the behaviors of black and white individuals, only to find consistent superiority of the whites."

The researchers then asked participants, for each version of the post, to rate factors like "how much they agreed with the message," "how accurate they found it," "how much they liked the writer," and, significantly, how likely they were to share the post with others

Their findings? "Frequent users are particularly disposed to be influenced by negative racial messages." The group of more-frequent Facebook users didn't differ from others in their reaction to the egalitarian message. But those users "were more positive toward the messages with racist content -- particularly the superiority message." 

the brain is a malleable organ. Every time you do an activity, or have a thought, you are changing a piece of yourself into something slightly different than it was before. Every hour you spend with others, you become more like the people around you.

Gradually, you become a different person. If there is a large gap between your daily conduct and your core commitment, you will become more like your daily activities and less attached to your original commitment. You will become more hedge fund, less malaria.

I would worry about turning yourself into a means rather than an end. If you go to Wall Street mostly to make money for charity, you may turn yourself into a machine for the redistribution of wealth. You may turn yourself into a fiscal policy.

power essentially comes in three varieties: the ability to compel people to do what they don’t want to do; the capability to stop them doing what they want to do; and the power to shape the way they think

This last is the kind of power exercised by our mass media. They can shape the public (and therefore the political) agenda by choosing the news that people read, hear or watch; and they can shape the ways in which that news is presented.

For a long time, Google was the 800lb gorilla in this domain, because its dominance of search determined what people could find in the unimaginable wastelands of cyberspace

The day-in, day-out work of the politician is the management of electoral coalitions: coaxing, cajoling, compelling people to work together who—in the more natural course of things—might have nothing in common

Unlike writers and intellectuals, politicians don’t have the freedom to work only with people they like and admire. Unlike writers and intellectuals, they have no duty to speak aloud their inner convictions—their work would become impossible if they did.

Politics unfortunately abounds in shams that must be treated reverentially for every politician who would succeed. If you are the sort of man whose stomach revolts against treating shams reverentially, you will be well advised to stay out of politics altogether and set up as a prophet; your prophecies may perhaps sow good seed for some future harvest. But as a politician you would be impotent. For at any given time the bulk of your countrymen believe firmly and devoutly, not only in various things that are worthy of belief, but also in illusions of one kind and another; and they will never submit to have their affairs managed for them by one who appears not to share in their credulity.

“go to college” is such a proven prescription

college graduates have lower unemployment rates, earn higher wages and even have longer-lasting marriages

7.2 million students who need federal loans to attend college

"Most neuroscientific research has been devoted to negative symptoms — depression and addiction, instead of joy," says Donatella Marazziti, an Italian psychiatrist who has studied neurotransmitter levels in the brains of people who've recently fallen in love.

And she's found that a brain in the initial stage of love looks surprisingly like a brain experiencing a drug addiction.

This, Fisher says, explains the feeling of obsession many people experience when falling in love. "It's what gives you the elation and the craving that is basic to romantic love.

How Phantom Limbs Explain Consciousness

Almost all people who have an amputation experience a phantom. Usually the effect fades within days, but in some cases it can remain for a lifetime.

The brain constructs a model of the self that neuroscientists call the body schema. The body schema is a simulation. It takes in touch, vision, and baseline information about what’s connected to what, and builds a virtual model of your body.

use those machines to examine the genetic underpinnings of genius like his own. He wants nothing less than to crack the code for intelligence by studying the genomes of thousands of prodigies, not just from China but around the world.

fully expect they will succeed in identifying a genetic basis for IQ. They also expect that within a decade their research will be used to screen embryos during in vitro fertilization, boosting the IQ of unborn children by up to 20 points. In theory, that’s the difference between a kid who struggles through high school and one who sails into college.

studies make it clear that IQ is strongly correlated with the ability to solve all sorts of abstract problems, whether they involve language, math, or visual patterns. The frightening upshot is that IQ remains by far the most powerful predictor of the life outcomes that people care most about in the modern world. Tell me your IQ and I can make a decently accurate prediction of your occupational attainment, how many kids you’ll have, your chances of being arrested for a crime, even how long you’ll live.

"I am in the camp that is concerned about super intelligence," Gates wrote. "First the machines will do a lot of jobs for us and not be super intelligent. That should be positive if we manage it well. A few decades after that though the intelligence is strong enough to be a concern. I agree with Elon Musk and some others on this and don't understand why some people are not concerned."

The media scandal of 2016 isn’t so much about what reporters failed to tell the American public; it’s about what they did report on, and the fact that it didn’t seem to matter.

Facebook and Snapchat and the other social media sites should rightfully be doing a lot of soul-searching about their role as the most efficient distribution network for conspiracy theories, hatred, and outright falsehoods ever invented.

I’ve been obsessively looking back over our coverage, too, trying to figure out what we missed along the way to the upset of the century

rather than stating the optimal, rational answer, as an economist of the time might have, they quantified how most real people, consistently, make a less-rational choice. Their work treated economics not as a perfect or self-correcting machine, but as a system prey to quirks of human perception. The field of behavioral economics was born.

Tversky and calls for a new form of academic cooperation, marked not by turf battles but by "adversarial collaboration," a good-faith effort by unlike minds to conduct joint research, critiquing each other in the service of an ideal of truth to which both can contribute.

The theme of the talk was “Is Mass Extinction of Life on Earth Inevitable?”

the resurrection of extinct species, like the woolly mammoth, aided by new genomic technologies developed by the Harvard molecular biologist George Church.

Microsoft, in an emailed statement, described the machine-learning project as a social and cultural experiment.

Microsoft said the artificial intelligence project had been designed to “engage and entertain people” through “casual and playful conversation,” and that it was built through mining public data. It was targeted at 18- to 24-year-olds in the United States and was developed by a staff that included improvisational comedians.

social networking sites create pressure to put time and effort into tending weak ties, and how it can be impossible to keep up with them all. Personally, I also find it difficult to keep up with my strong ties. I’m a great “pick up where we left off” friend, as are most of the people closest to me (makes sense, right?). I’m decidedly sub-awesome, however, at being in constant contact with more than a few people at a time.

the devolution of friendship. As I explain over the course of this essay, I link the devolution of friendship to—but do not “blame” it on—the affordances of various social networking platforms, especially (but not exclusively) so-called “frictionless sharing” features.

I’m using the word here in the same way that people use it to talk about the devolution of health care. One example of devolution of health care is some outpatient surgeries: patients are allowed to go home after their operations, but they still require a good deal of post-operative care such as changing bandages, irrigating wounds, administering medications, etc. Whereas before these patients would stay in the hospital and nurses would perform the care-labor necessary for their recoveries, patients must now find their own caregivers (usually family members or friends; sometimes themselves) to perform free care-labor. In this context, devolution marks the shift of labor and responsibility away from the medical establishment and onto the patient; within the patient-medical establishment collaboration, the patient must now provide a greater portion of the necessary work. Similarly, in some ways, we now expect our friends to do a greater portion of the work of being friends with us.

Northeastern University psychology professor Lisa Feldman Barrett found, for the first time, that the neurotransmitter dopamine is involved in human bonding, bringing the brain's reward system into our understanding of how we form human attachments.

To conduct the study, the researchers turned to a novel technology: a machine capable of performing two types of brain scans simultaneously -- functional magnetic resonance imaging, or fMRI, and positron emission tomography, or PET.

Barrett's team focused on the neurotransmitter dopamine, a chemical that acts in various brain systems to spark the motivation necessary to work for a reward.

But after seeing ads from Coca-Cola, Procter & Gamble and Wal-Mart appear next to racist, anti-Semitic or terrorist videos, its engineers realized their computer models had a blind spot: They did not understand context.

Now teaching computers to understand what humans can readily grasp may be the key to calming fears among big-spending advertisers that their ads have been appearing alongside videos from extremist groups and other offensive messages.

But the recent problems opened Google to criticism that it was not doing enough to look out for advertisers. It is a significant problem for a multibillion-dollar company that still gets most of its revenue through advertising.

we have sacrificed conversation for mere connection.

the little devices most of us carry around are so powerful that they change not only what we do, but also who we are.

A businessman laments that he no longer has colleagues at work. He doesn’t stop by to talk; he doesn’t call. He says that he doesn’t want to interrupt them. He says they’re “too busy on their e-mail.”
