In Europe, nine out of 10 students study a foreign language. In the United States, only one in five do. Between 1997 and 2008, the number of American middle schools offering foreign languages dropped from 75 percent to 58 percent. Between 2009 and 2013, one American college closed its foreign language program; between 2013 and 2017, 651 others did the same.

At first glance, these statistics look like a tragedy. But I am starting to harbor the odd opinion that maybe they are not. What is changing my mind is technology.

what about spoken language? I was in Belgium not long ago, and I watched various tourists from a variety of nations use instant speech translation apps to render their own languages into English and French. The newer ones can even reproduce the tone of the speaker’s voice; a leading model, iTranslate, publicizes that its Translator app has had 200 million downloads so far.

if all of those bad presentations really led to broad societal ills, the proof is hard to find.

Some scientists have tried to take a formal measure of the alleged PowerPoint Effect, asking whether the software really influences our ability to process information. Sebastian Kernbach, a professor of creativity and design at the University of St. Gallen, in Switzerland, has co-authored multiple reviews synthesizing this literature. On the whole, he told me, the research suggests that Tufte was partly right, partly wrong. PowerPoint doesn’t seem to make us stupid—there is no evidence of lower information retention or generalized cognitive decline, for example, among those who use it—but it does impose a set of assumptions about how information ought to be conveyed: loosely, in bullet points, and delivered by presenters to an audience of passive listeners. These assumptions have even reshaped the physical environment for the slide-deck age, Kernbach said: Seminar tables, once configured in a circle, have been bent, post-PowerPoint, into a U-shape to accommodate presenters.

When I spoke with Kernbach, he was preparing for a talk on different methods of visual thinking to a group of employees at a large governmental organization. He said he planned to use a flip chart, draw on blank slides like a white board, and perhaps even have audience members do some drawing of their own. But he was also gearing up to use regular old PowerPoint slides. Doing so, he told me, would “signal preparation and professionalism” for his audience. The organization was NASA.

Andy Clark admits it’s strange that he took up “predictive processing,” an ambitious leading theory of how the brain works. A philosopher of mind at the University of Sussex, he has devoted his career to how thinking doesn’t occur just between the ears—that it flows through our bodies, tools, and environments. “The external world is functioning as part of our cognitive machinery

But 15 years ago, he realized that had to come back to the center of the system: the brain. And he found that predictive processing provided the essential links among the brain, body, and world.

There’s a traditional view that goes back at least to Descartes that perception was about the imprinting of the outside world onto the sense organs. In 20th-century artificial intelligence and neuroscience, vision was a feed-forward process in which you took in pixel-level information, refined it into a two and a half–dimensional sketch, and then refined that into a full world model.

Social media has redefined human connection, especially if you’re part of the millennial or Gen Z generation. It is so deeply interwoven into every aspect of our lives that it’s almost impossible for us to withdraw from our digital devices

there’s another side to social media, one about which mental health experts have been sounding the alarm for years: how our social media consumption compares to cocaine or alcohol addiction. And how it’s contributing to a growing mental health crisis among youths.

“Human connection is vital for survival. We’re programed over millions of years of evolution to connect with other people,”

there also seems to be little doubt that is corroding the web.

, two new studies offered some cause for alarm. (I discovered both in the latest edition of Import AI, the indispensable weekly newsletter from Anthropic co-founder and former journalist Jack Clark.)

The first study, which had an admittedly small sample size, found that crowd-sourced workers on Amazon’s Mechanical Turks platforms increasingly admit to using LLMs to perform text-based tasks.

Von Neumann, too, was deeply concerned about the inability of humanity to keep up with its own inventions. “What we are creating now,” he said to his wife Klári in 1945, “is a monster whose influence is going to change history, provided there is any history left.” Moving to the subject of future computing machines he became even more agitated, foreseeing disaster if “people” could not “keep pace with what they create.”

Oppenheimer, Einstein, von Neumann and other Institute faculty channeled much of their effort toward what AI researchers today call the “alignment” problem: how to make sure our discoveries serve us instead of destroying us. Their approaches to this increasingly pressing problem remain instructive.

Von Neumann focused on applying the powers of mathematical logic, taking insights from games of strategy and applying them to economics and war planning. Today, descendants of his “game theory” running on von Neumann computing architecture are applied not only to our nuclear strategy, but also many parts of our political, economic and social lives. This is one approach to alignment: humanity survives technology through more technology, and it is the researcher’s role to maximize progress.

The way people post on Twitter is different from the way people post on LinkedIn which is different than how people post Facebook which is different from the way people post on Instagram, no matter how much Facebook keeps telling you to cross-post your IG stories

Some people whose job relies on onlineness (like me) have to refine their voices, their ways of being, across several platforms. But most normal people have found their lane — the medium that fits their message — and have stuck with it.

People post where they feel public speech “belongs.”

According to “fourth turning” proponents, American history goes through recurring cycles. Each one, which lasts about 80 to 100 years, consists of four generation-long seasons, or “turnings.” The winter season is a time of upheaval and reconstruction — a fourth turning.

The theory first appeared in “The Fourth Turning,” a work of pop political science that has had a cult following more or less since it was published in 1997. In the last few years of political turmoil, the book and its ideas have bubbled into the mainstream.

According to “The Fourth Turning,” previous crisis periods include the American Revolution, the Civil War and World War II. America entered its latest fourth turning in the mid-2000s. It will culminate in a crisis sometime in the 2020s — i.e., now.

With great exhaustion, we hereby rehearse the backstory. In 2006, a handful of mostly already successful tech entrepreneurs started Twitter as a weird experiment for posting short textual quips.

Twitter never thrived like its social-media cousins.

Then, last year, Musk bought it and started dismantling the place. Users longed to recover stability or eschew toxicity, as if those properties had ever really been present on Twitter, a profoundly unstable and abusive place.

for the past few years, these books have been written by Colleen Hoover.

What is it about Hoover’s stories — which dwell largely in romance, but also include a thriller and a ghost story — that women are drawn to?

I slorped down three of them in one week. I found myself carrying them from room to room, slipping in what would begin as “just a few pages” but then stretch into hours’ worth.

There is no clinical definition for food noise, but the experts and patients interviewed for this article generally agreed it was shorthand for constant rumination about food. Some researchers associate the concept with “hedonic hunger,” an intense preoccupation with eating food for the purpose of pleasure, and noted that it could also be a component of binge eating disorder, which is common but often misunderstood.

“It just seems to be that some people are a little more wired this way,” he said. Obsessive rumination about food is most likely a result of genetic factors as well as environmental exposure and learned habits

The active ingredient in Ozempic and Wegovy is semaglutide, a compound that affects the areas in the brain that regulate appetite, Dr. Gabbay said; it also prompts the stomach to empty more slowly, making people taking the medication feel fuller faster and for longer. That satiation itself could blunt food noise
