But to understand why Republicans have died at higher rates, you can’t look at vaccine status alone. Congressional districts controlled by a trifecta of Republican leaders—state governor, Senate, and House—had an 11 percent higher death rate, according to the Lancet study. A likely explanation, the authors write, could be that in the post-vaccine era, those leaders chose policies and conveyed public-health messages that made their constituents more likely to die. Although we still can’t say these decisions led to higher death rates, the association alone is jarring.

One of the most compelling studies comes from researchers at Yale, who published their findings as a working paper in November. They link political party and excess-death rate—the percent increase in deaths above pre-COVID levels—among those registered as either Democrats or Republicans, providing a more granular view. They chose to analyze data from Florida and Ohio from before and after vaccines were available. Looking at the period before the vaccine,  researchers found a 1.6 percentage-point difference in excess death rate among Republicans and Democrats, with a higher rate among Republicans. But after vaccines became available, that gap widened dramatically to 10.4 percentage points, again with a higher Republican excess death rate. “When we compare individuals who are of the same age, who live in the same county in the same month of the pandemic, there are differences correlated with your political-party affiliation that emerge after vaccines are available,”

What’s most concerning about all of this is that partisan disparities in death rates were also apparent before COVID. People living in Republican jurisdictions have been at a health disadvantage for more than 20 years. From 2001 to 2019, the death rate in Democratic counties decreased by 22 percent, according to a recent study; in Republican counties, it declined by only 11 percent. In the same time period, the political gap in death rates increased sixfold.

over the decades, state policy decisions on health issues such as Medicaid, gun legislation, tobacco taxes, and, indeed, vaccines have likely had a stronger impact on state health trajectories than other factors

the long-term decline of health in red states indicates that there is an ongoing problem at a high level in Republican-led places, and that something has gone awry. “If you happen to live in certain states, your chances for living a long life are going to be much higher than if you’re an American living in a different state,”

o acknowledge how many Republicans didn’t have to die would mean giving credence to scientific and medical expertise. So long as America remains locked in a poisonous partisan battle in which science is wrongly dismissed as being associated with the left, the death toll will only rise.

The sour mood surrounding Mr. Musk is beginning to rub off on German drivers, with a clear majority saying his takeover of Twitter has had a negative effect on Tesla’s image, especially among women and among people 50 or older.

Nearly half of Germans who are contemplating or actively looking to buy a new car said the Twitter takeover had turned them away from considering a Tesla

Tesla’s sales in China through November were 59 percent higher than a year earlier, according to data from the China Passenger Car Association, but that was slower than overall growth of “new energy vehicles” — a category that includes all-electric cars and plug-in hybrids. Sales of these vehicle have doubled, while BYD, the market leader, increased its sales more than threefold

a “builder class”—a brains trust of youngish idealists, which includes Patrick Collison, co-founder of Stripe, a payments firm valued at $74bn, and other (mostly white and male) techies, who are posing questions that go far beyond the usual interests of Silicon Valley’s titans. They include the future of man and machine, the constraints on economic growth, and the nature of government.

They share other similarities. Business provided them with their clout, but doesn’t seem to satisfy their ambition

The number of techno-billionaires in America (Mr Collison included) has more than doubled in a decade.

ome of them, like the Medicis in medieval Florence, are keen to use their money to bankroll the intellectual ferment

The other is Paul Graham, co-founder of Y Combinator, a startup accelerator, whose essays on everything from cities to politics are considered required reading on tech campuses.

Mr Altman puts it more optimistically: “The iPhone and cloud computing enabled a Cambrian explosion of new technology. Some things went right and some went wrong. But one thing that went weirdly right is a lot of people got rich and said ‘OK, now what?’”

A belief that with money and brains they can reboot social progress is the essence of this new mindset, making it resolutely upbeat

The question is: are the rest of them further evidence of the tech industry’s hubristic decadence? Or do they reflect the start of a welcome capacity for renewal?

Two well-known entrepreneurs from that era provided the intellectual seed capital for some of today’s techno nerds.

Mr Thiel, a would-be libertarian philosopher and investor

This cohort of eggheads starts from common ground: frustration with what they see as sluggish progress in the world around them.

In the 2000s Mr Thiel supported the emergence of a small community of online bloggers, self-named the “rationalists”, who were focused on removing cognitive biases from thinking (Mr Thiel has since distanced himself). That intellectual heritage dates even further back, to “cypherpunks”, who noodled about cryptography, as well as “extropians”, who believed in improving the human condition through life extensions

the rationalist movement has hit the mainstream. The result is a fascination with big ideas that its advocates believe goes beyond simply rose-tinted tech utopianism

A burgeoning example of this is “progress studies”, a movement that Mr Collison and Tyler Cowen, an economist and seer of the tech set, advocated for in an article in the Atlantic in 2019

Progress, they think, is a combination of economic, technological and cultural advancement—and deserves its own field of study

There are other examples of this expansive worldview. In an essay in 2021 Mr Altman set out a vision that he called “Moore’s Law for Everything”, based on similar logic to the semiconductor revolution. In it, he predicted that smart machines, building ever smarter replacements, would in the coming decades outcompete humans for work. This would create phenomenal wealth for some, obliterate wages for others, and require a vast overhaul of taxation and redistribution

His two bets, on OpenAI and nuclear fusion, have become fashionable of late—the former’s chatbot, ChatGPT, is all the rage. He has invested $375m in Helion, a company that aims to build a fusion reactor.

Mr Lonsdale, who shares a libertarian streak with Mr Thiel, has focused attention on trying to fix the shortcomings of society and government. In an essay this year called “In Defence of Us”, he argues against “historical nihilism”, or an excessive focus on the failures of the West.

With a soft spot for Roman philosophy, he has created the Cicero Institute in Austin that aims to inject free-market principles such as competition and transparency into public policy.

He is also bringing the startup culture to academia, backing a new place of learning called the University of Austin, which emphasises free speech.

All three have business ties to their mentors. As a teen, Mr Altman was part of the first cohort of founders in Mr Graham’s Y Combinator, which went on to back successes such as Airbnb and Dropbox. In 2014 he replaced him as its president, and for a while counted Mr Thiel as a partner (Mr Altman keeps an original manuscript of Mr Thiel’s book “Zero to One” in his library). Mr Thiel was also an early backer of Stripe, founded by Mr Collison and his brother, John. Mr Graham saw promise in Patrick Collison while the latter was still at school. He was soon invited to join Y Combinator. Mr Graham remains a fan: “If you dropped Patrick on a desert island, he would figure out how to reproduce the Industrial Revolution,”

While at university, Mr Lonsdale edited the Stanford Review, a contrarian publication co-founded by Mr Thiel. He went on to work for his mentor and the two men eventually helped found Palantir. He still calls Mr Thiel “a genius”—though he claims these days to be less “cynical” than his guru.

“The tech industry has always told these grand stories about itself,” says Adrian Daub of Stanford University and author of the book, “What Tech Calls Thinking”. Mr Daub sees it as a way of convincing recruits and investors to bet on their risky projects. “It’s incredibly convenient for their business models.”

Yet the impact could ultimately be positive. Frustrations with a sluggish society have encouraged them to put their money and brains to work on problems from science funding and the redistribution of wealth to entirely new universities. Their exaltation of science may encourage a greater focus on hard tech

Silicon Valley has shown an uncanny ability to reinvent itself in the past.

Medical staff say they could have avoided the medicine shortages that have forced some facilities to ration drugs. There also could have been more time to set up a more effective triage system to avoid overcrowding

ne of the fundamental problems with China’s health system is its overreliance on hospitals for even the most basic care.

“In the U.S. people have their own primary physicians, but there are few ways in China to get care from the medical system except to go to an E.R. at a big hospital,” said Dr. Qiao Renli, a pulmonary and critical care doctor at the University of Southern California, who has taught and practiced medicine in both China and the United States.

The deluge of Covid patients is not the only challenge hospitals are facing. One of the ripple effects of the outbreak has been a widespread shortage of blood for transfusions because of the shrinking pool of eligible donors.In the southwestern city of Kunming, a blood bank said in a statement that the city was getting a fraction of the 500 donors per day it needs to keep up with demand, and that the shortage had started to affect pregnant women and patients in intensive care units.

During the 20th century, the list got much longer. In came existential crises, midlife crises, energy crises and environmental crises. When Koselleck was writing about the subject in the 1970s, he counted up more than 200 kinds of crisis we could then face

Waking up each morning to hear about the latest crisis is dispiriting for some, but throughout history it has been a bracing experience for others. In 1857, Friedrich Engels wrote in a letter that “the crisis will make me feel as good as a swim in the ocean”. A hundred years later, John F Kennedy (wrongly) pointed out that in the Chinese language, the word “crisis” is composed of two characters, “one representing danger, and the other, opportunity”. More recently, Elon Musk has argued “if things are not failing, you are not innovating enough”.

Victor H Mair, a professor of Chinese literature at the University of Pennsylvania, points out that in fact the Chinese word for crisis, wēijī, refers to a perilous situation in which you should be particularly cautious

“Those who purvey the doctrine that the Chinese word for ‘crisis’ is composed of elements meaning ‘danger’ and ‘opportunity’ are engaging in a type of muddled thinking that is a danger to society,” he writes. “It lulls people into welcoming crises as unstable situations from which they can benefit.” Revolutionaries, billionaires and politicians may relish the chance to profit from a crisis, but most people world prefer not to have a crisis at all.

A 2019 study which involved observing participants using bricks, found that those who had been threatened before the task tended to come up with more harmful uses of the bricks (such as using them as weapons) than people who did not feel threatened

The first world war sparked the growth of modernism in painting and literature. The second fuelled innovations in science and technology. The economic crises of the 1970s and 80s are supposed to have inspired the spread of punk and the creation of hip-hop

psychologists have also found that when we are threatened by a crisis, we become more rigid and locked into our beliefs. The creativity researcher Dean Simonton has spent his career looking at breakthroughs in music, philosophy, science and literature. He has found that during periods of crisis, we actually tend to become less creative.

When he looked at 5,000 creative individuals over 127 generations in European history, he found that significant creative breakthroughs were less likely during periods of political crisis and instability.

A common folk theory is that times of great crisis also lead to great bursts of creativity.

These are innovations that tend to be harmful – such as new weapons, torture devices and ingenious scams.

psychologists have found that it is what they call “malevolent creativity” that flourishes when we feel threatened by crisis.

Students presented with information about a threatening situation tended to become increasingly wary of outsiders, and even begin to adopt positions such as an unwillingness to support LGBT people afterwards.

during moments of crisis – when change is really needed – we tend to become less able to change.

When we suffer significant traumatic events, we tend to have worse wellbeing and life outcomes.

, other studies have shown that in moderate doses, crises can help to build our sense of resilience.

we tend to be more resilient if a crisis is shared with others. As Bruce Daisley, the ex-Twitter vice-president, notes: “True resilience lies in a feeling of togetherness, that we’re united with those around us in a shared endeavour.”

Crises are like many things in life – only good in moderation, and best shared with others

The challenge our leaders face during times of overwhelming crisis is to avoid letting us plunge into the bracing ocean of change alone, to see if we sink or swim. Nor should they tell us things are fine, encouraging us to hide our heads in the san

during moments of significant crisis, the best leaders are able to create some sense of certainty and a shared fate amid the seas of change.

This means people won’t feel an overwhelming sense of threat. It also means people do not feel alone. When we feel some certainty and common identity, we are more likely to be able to summon the creativity, ingenuity and energy needed to change things.

Until recently, the people said, Meta executives viewed the company’s reliance on China to make Oculus virtual reality headsets as a relatively minor concern because the company’s core focus was its social media and messaging apps.

All that has changed now that Meta has rebranded itself as a hardware company

“Meta is building a complicated hardware product. You can’t just turn on a dime and make it elsewhere,”

Facebook’s public criticism of China began in 2019 when Zuckerberg warned, in a speech at Georgetown University, that China was exporting a dangerous vision for the internet to the rest of the world — and noted that Facebook was abandoning its efforts to break into that country’s market.

The anti-China stance has since extended into a full-blown corporate strategy. Nick Clegg, the company’s president, wrote an op-ed attacking China in The Washington Post in 2020, the same year Zuckerberg attacked China in a congressional antitrust hearing.

At the antitrust hearing in Congress in 2020, Zuckerberg used his opening remarks to attack China in terms that went much further than his industry peers. He said it was “well-documented that the Chinese government steals technology from American companies,” and repeated that the country was “building its own version of the internet” that went against American values. He described Facebook as a “proudly American” company and noted that TikTok was the company’s fastest-growing rival.

“They were trying to find things that [Zuckerberg] could agree with Trump on, and it’s a pretty slim list,” said one of the people, describing how the company landed on its anti-China strategy. “If you’re not going to try to be in this country anyway, you might as well use it to your political advantage by contrasting yourself with Apple and TikTok.”

What happened in 2012, when the oldest Gen-Z babies were in their middle teens? That was the year Facebook acquired Instagram and young people flocked to the latter site. It was also “the beginning of the selfie era.”

Mr. Haidt’s research, confirmed by that of others, shows that depression rates started to rise “all of a sudden” around 2013, “especially for teen girls,” but “it’s only Gen Z, not the older generations.” If you’d stopped collecting data in 2011, he says, you’d see little change from previous years. “By 2015 it’s an epidemic.” (His data are available in an open-source document.)

Mr. Haidt imagines “literally launching our children into outer space” and letting their bodies grow there: “They would come out deformed and broken. Their limbs wouldn’t be right. You can’t physically grow up in outer space. Human bodies can’t do that.” Yet “we basically do that to them socially. We launched them into outer space around the year 2012,” he says, “and then we expect that they will grow up normally without having normal human experiences.”

Social media and selfies hit a generation that had led an overprotected childhood, in which the age at which children were allowed outside on their own by parents had risen from the norm of previous generations, 7 or 8, to between 10 and 12.

That meant the first social-media generation was one of “weakened kids” who “hadn’t practiced the skills of adulthood in a low-stakes environment” with other children. They were deprived of “the normal toughening, the normal strengthening, the normal anti-fragility.

Now, their childhood “is largely just through the phone. They no longer even hang out together.” Teenagers even drive less than earlier generations did.

Mr. Haidt especially worries about girls. By 2020 more than 25% of female teenagers had “a major depression.” The comparable number for boys was just under 9%.

The comparable numbers for millennials at the same age registered at half the Gen-Z rate: about 13% for girls and 5% for boys. “Kids are on their devices all the time,”

Most girls, by contrast, are drawn to “visual platforms,” Instagram and TikTok in particular. “Those are about display and performance. You post your perfect life, and then you flip through the photos of other girls who have a more perfect life, and you feel depressed.

He calls this phenomenon “compare and despair” and says: “It seems social because you’re communicating with people. But it’s performative. You don’t actually get social relationships. You get weak, fake social links.”

Mr. Haidt says he has no antipathy toward the young, and he calls millennials “amazing.”

To illustrate his point about Gen Z, Mr. Haidt challenges people to name young people today who are “really changing the world, who are doing big things that have an impact beyond their closed ecosystem.”

He can think of only two, neither of them American: Greta Thunberg, 19, the Swedish climate militant, and Malala Yousafzai, 25, the Pakistani advocate for female education

I’m predicting that they will be less effective, less impactful, than previous generations.” Why? “You should always keep your eye on whether people are in ‘discover mode’ or ‘defend mode.’ ” In the former mode, you seize opportunities to be creative. In the latter, “you’re not creative, you’re not future-thinking, you’re focused on threats in the present.”

University students who matriculated starting in 2014 or so have arrived on campus in defend mode: “Here they are in the safest, most welcoming, most inclusive, most antiracist places on the planet, but many of them were acting like they were entering some sort of dystopian, threatening, immoral world.”

56% of liberal women 18 to 29 responded affirmatively to the question: Has a doctor or other healthcare provider ever told you that you have a mental health condition? “Some of that,” Mr. Haidt says, “has to be just self-presentational,” meaning imagined.

This new ideology . . . valorizes victimhood. And if your sub-community motivates you to say you have an anxiety disorder, how is this going to affect you for the rest of your life?” He answers his own question: “You’re not going to take chances, you’re going to ask for accommodations, you’re going to play it safe, you’re not going to swing for the fences, you’re not going to start your own company.”

Whereas millennial women are doing well, “Gen-Z women, because they’re so anxious, are going to be less successful than Gen-Z men—and that’s saying a lot, because Gen-Z men are messed up, too.”

The problem, he says, is distinct to the U.S. and other English-speaking developed countries: “You don’t find it as much in Europe, and hardly at all in Asia.” Ideas that are “nurtured around American issues of race and gender spread instantly to the U.K. and Canada. But they don’t necessarily spread to France and Germany, China and Japan.”

something I hear from a lot of managers, that it’s very difficult to supervise their Gen-Z employees, that it’s very difficult to give them feedback.” That makes it hard for them to advance professionally by learning to do their jobs better.

“this could severely damage American capitalism.” When managers are “afraid to speak up honestly because they’ll be shamed on Twitter or Slack, then that organization becomes stupid.” Mr. Haidt says he’s “seen a lot of this, beginning in American universities in 2015. They all got stupid in the same way. They all implemented policies that backfire.”

Mr. Haidt, who describes himself as “a classical liberal like John Stuart Mill,” also laments the impact of social media on political discourse

“Social media is incompatible with liberal democracy because it has moved conversation, and interaction, into the center of the Colosseum. We’re not there to talk to each other. We’re there to perform” before spectators who “want blood.”

Is there a solution? “I’d raise the age of Internet adulthood to 16,” he says—“and enforce it.”

By contrast, “life went onto phone-based apps 10 years ago, and the protections we have for children are zero, absolutely zero.” The damage to Generation Z from social media “so vastly exceeds the damage from Covid that we’re going to have to act.”

Gen Z, he says, “is not in denial. They recognize that this app-based life is really bad for them.” He reports that they wish they had childhoods more like those of their parents, in which they could play outside and have adventur

Like all of these books, it is about the power and untrustworthiness of written texts—history texts in particular. These various strands don’t always cohere. The question of who killed Bonkowski Pasha is part of the main story of the novel, and yet it disappears for chapters at a time. Perhaps more seriously, the postmodern elements sometimes sit uncomfortably with the torrents of historical and sensory detail

Authoritarian governments have created seemingly realistic news broadcasters to advance their political goals

Experts fear the technology could hasten an erosion of trust in media, in government and in society. If any image can be manufactured — and manipulated — how can we believe anything we see?

“The tools are going to get better, they’re going to get cheaper, and there will come a day when nothing you see on the internet can be believed,” said Wasim Khaled, chief executive of Blackbird.AI, a company that helps clients fight disinformation.

Artificial intelligence allows virtually anyone to create complex artworks, like those now on exhibit at the Gagosian art gallery in New York, or lifelike images that blur the line between what is real and what is fiction. Plug in a text description, and the technology can produce a related image — no special skills required.

Midjourney’s images, he said, were able to pass muster in facial-recognition programs that Bellingcat uses to verify identities, typically of Russians who have committed crimes or other abuses. It’s not hard to imagine governments or other nefarious actors manufacturing images to harass or discredit their enemies.

In February, Getty accused Stability AI of illegally copying more than 12 million Getty photos, along with captions and metadata, to train the software behind its Stable Diffusion tool. In its lawsuit, Getty argued that Stable Diffusion diluted the value of the Getty watermark by incorporating it into images that ranged “from the bizarre to the grotesque.”

Getty’s lawsuit reflects concerns raised by many individual artists — that A.I. companies are becoming a competitive threat by copying content they do not have permission to use.

Trademark violations have also become a concern: Artificially generated images have replicated NBC’s peacock logo, though with unintelligible letters, and shown Coca-Cola’s familiar curvy logo with extra O’s looped into the name.

The threat to photographers is fast outpacing the development of legal protections, said Mickey H. Osterreicher, general counsel for the National Press Photographers Association

Newsrooms will increasingly struggle to authenticate conten

Social media users are ignoring labels that clearly identify images as artificially generated, choosing to believe they are real photographs, he said.

The video explained that the deepfake had been created, with Ms. Schick’s consent, by the Dutch company Revel.ai and Truepic, a California company that is exploring broader digital content verification

The companies described their video, which features a stamp identifying it as computer-generated, as the “first digitally transparent deepfake.” The data is cryptographically sealed into the file; tampering with the image breaks the digital signature and prevents the credentials from appearing when using trusted software.

The companies hope the badge, which will come with a fee for commercial clients, will be adopted by other content creators to help create a standard of trust involving A.I. images.

“The scale of this problem is going to accelerate so rapidly that it’s going to drive consumer education very quickly,” said Jeff McGregor, chief executive of Truepic

Adobe unveiled its own image-generating product, Firefly, which will be trained using only images that were licensed or from its own stock or no longer under copyright. Dana Rao, the company’s chief trust officer, said on its website that the tool would automatically add content credentials — “like a nutrition label for imaging” — that identified how an image had been made. Adobe said it also planned to compensate contributors.

Blend these factors — a desire for escape from our virtual lives; bidding as fast as pushing a button; and the promotion of new collecting fields like outdated technology devices — and you have Heritage Auctions in Dallas.

Heritage is a whirlwind of activity, of passion, of hype, constantly trying new ways of enticing people to own something beautiful and useless. Ninety-one million Americans, according to U.S. Census Bureau surveys, are having trouble paying household bills. Everyone else is a potential bidder.

Twenty years ago, Heritage had four categories: coins, comics, movie posters and sports. Now it has more than 50, which generated revenue of $1.4 billion last year. Everything, at least in theory, is collectible.

“We don’t question the value or legitimacy of a particular subject matter relative to outmoded norms,” Mr. Benesh said. “We’re not here to tell you what’s worthwhile. The marketplace will tell you. The bidders” — Heritage has 1.6 million — “will tell you.”

In mid-2020, the privately held company moved to a 160,000-square-foot building by Dallas-Fort Worth International Airport, doubling the size of its former headquarters. Hundreds of specialists, most of them collectors themselves, prepare hundreds of thousands of items for bids here — researching, photographing, writing catalog copy.

The problem is, older historical items that were previously unknown are becoming rare. Every barn, basement and attic has been ransacked for treasures. New items related to Washington or Lincoln, for instance, are nearly impossible to find.

For researchers concerned with more immediate AI risks, such as bias, disinformation and job displacement, the voices of doom are a distraction. Professor Brent Mittelstadt, director of research at the Oxford Internet Institute, said the warnings of “the existential risks community” are overblown. “The problem is you can’t disprove the future scenarios . . . in the same way you can’t disprove science fiction.” Emily Bender, a professor of linguistics at the University of Washington, believes the doomsters are propagating “unhinged AI hype, helping those building this stuff sell it”.

Those urging us to stop, pause and think again have a useful card up our sleeves: the people building these models do not fully understand them. AI like ChatGPT is made up of huge neural networks that can defy their creators by coming up with “emergent properties”.

Google’s PaLM model started translating Bengali despite not being trained to do so

Let’s not forget the excitement, because that is also part of Moloch, driving us forward. The lure of AI’s promises for humanity has been hinted at by DeepMind’s AlphaFold breakthrough, which predicted the 3D structures of nearly all the proteins known to humanity.

Noam Shazeer, a former Google engineer credited with setting large language models such as ChatGPT on their present path, was asked by The Sunday Times how the models worked. He replied: “I don’t think anybody really understands how they work, just like nobody really understands how the brain works. It’s pretty much alchemy.”

The industry is turning itself to understanding what has been created, but some predict it will take years, decades even.

Alex Heath, deputy editor of The Verge, who recently attended an AI conference in San Francisco. “It’s clear the people working on generative AI are uneasy about the worst-case scenario of it destroying us all. These fears are much more pronounced in private than they are in public.” One figure building an AI product “said over lunch with a straight face that he is savoring the time before he is killed by AI”.

Greg Brockman, co-founder of OpenAI, told the TED2023 conference this week: “We hear from people who are excited, we hear from people who are concerned. We hear from people who feel both those emotions at once. And, honestly, that’s how we feel.”

A CBS interviewer challenged Sundar Pichai, Google’s chief executive, this week: “You don’t fully understand how it works, and yet you’ve turned it loose on society?

In 2020 there wasn’t a single drug in clinical trials developed using an AI-first approach. Today there are 18

Consider this from Bill Gates last month: “I think in the next five to ten years, AI-driven software will finally deliver on the promise of revolutionising the way people teach and learn.”

If the industry is aware of the risks, is it doing enough to mitigate them? Microsoft recently cut its ethics team, and researchers building AI outnumber those focused on safety by 30-to-1,

The concentration of AI power, which worries so many, also presents an opportunity to more easily develop some global rules. But there is little agreement on direction. Europe is proposing a centrally defined, top-down approach. Britain wants an innovation-friendly environment where rules are defined by each industry regulator. The US commerce department is consulting on whether risky AI models should be certified. China is proposing strict controls on generative AI that could upend social order.

Part of the drive to act now is to ensure we learn the lessons of social media. Twenty years after creating it, we are trying to put it back in a legal straitjacket after learning that its algorithms understand us only too well. “Social media was the first contact between AI and humanity, and humanity lost,” Yuval Harari, the Sapiens author,

Others point to bioethics, especially international agreements on human cloning. Tegmark said last week: “You could make so much money on human cloning. Why aren’t we doing it? Because biologists thought hard about this and felt this is way too risky. They got together in the Seventies and decided, let’s not do this because it’s too unpredictable. We could lose control over what happens to our species. So they paused.” Even China signed up.

One voice urging calm is Yann LeCun, Meta’s chief AI scientist. He has labelled ChatGPT a “flashy demo” and “not a particularly interesting scientific advance”. He tweeted: “A GPT-4-powered robot couldn’t clear up the dinner table and fill up the dishwasher, which any ten-year-old can do. And it couldn’t drive a car, which any 18-year-old can learn to do in 20 hours of practice. We’re still missing something big for human-level AI.” If this is sour grapes and he’s wrong, Moloch already has us in its thrall.

what worries me even more is the change I see in ordinary Americans. I live in the heart of MAGA country, and Donald Trump is the single most culturally influential person here. It’s not close. He’s far more influential than any pastor, politician, coach or celebrity. He has changed people politically and also personally. It is common for those outside the Trump movement to describe their aunts or uncles or parents or grandparents as “lost.” They mean their relatives’ lives are utterly dominated by Trump, Trump’s media and Trump’s grievances.

never before have I seen extremism penetrate a vast American community so deeply, so completely and so comprehensively.

That percentage is far higher than the (still troubling) 22 percent of independents and 13 percent of Democrats who shared the same view.

In 2011, they were the American cohort least likely to agree that a politician could commit immoral acts in private yet “still behave ethically and fulfill their duties in their public and professional life.”

They went from least likely to most likely to excuse the immoral behavior of politicians.

An increasing percentage are now tempted to embrace political violence. Last October, a startling 33 percent of Republicans (and an even larger 41 percent of pro-Trump Americans) agreed with the statement that “because things have gotten so far off track, true American patriots may have to resort to violence in order to save our country.”

Polling data again and again backs up the reality that the right is abandoning decency, and doing so in the most alarming of ways. It began happening almost immediately with white evangelicals

As the Iowa caucuses approached, Trump escalated his language, going so far as to call his political opponents “vermin” and declaring that immigrants entering America illegally are “poisoning the blood of our country.” The statement was so indefensible and repugnant that many expected it to hurt Trump. Yet a Des Moines Register/NBC News/Mediacom Iowa Poll found that a 42 percent plurality of likely Iowa Republican caucusgoers said the statement would make them more likely to support Trump — a substantially greater percentage than the 28 percent who said it would make them less likely to support him.

While political violence is hardly exclusive to the right, the hostility and vitriol embedded in MAGA America is resulting in an escalating wave of threats and acts of intimidation.

The result is a religious movement steeped in fanaticism but stripped of virtue. The fruit of the spirit described in Galatians in the New Testament — “love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control” — is absent from MAGA Christianity, replaced by the very “works of the flesh” the same passage warned against, including “hatreds, strife, jealousy, outbursts of anger, selfish ambitions, dissensions” and “factions.”

in the upside-down world of MAGA morality, vice is virtue and virtue is vice. My colleague Jane Coaston even coined a term, “vice signaling,” to describe how Trump’s core supporters convey their tribal allegiance. They’re often deliberately rude, transgressive or otherwise unpleasant, just to demonstrate how little they care about conventional moral norms.

For most of my life, conservative evangelicals (including me) have been fond of quoting John Adams’s 1798 letter to the Massachusetts Militia. It’s a critical founding document, one that forcefully argues that our Republic needs a virtuous citizenry to survive. “Our Constitution was made only for a moral and religious People,” he asserts. “It is wholly inadequate to the government of any other.”

I’ve appreciated that quote because it recognizes the obligations of a free people in a constitutional republic to exercise their liberty toward virtuous purposes.

Absent public virtue, a republic can fall. And a Trump win in 2024 would absolutely convince countless Americans that virtue is for suckers, and vice is the key to victory.

if he wins again, the equation will change and history may record that he was not the culmination of a short-lived reactionary moment, but rather the harbinger of a greater darkness to come.

The answer to both lies in one word: satiety. It’s a concept that we don’t use much in everyday life but that we’ve all experienced at some point. It describes the sensation of having had enough and not wanting any more.

The primary reason we have gained weight at a pace unprecedented in human history is that our diets have radically changed in ways that have deeply undermined our ability to feel sated

The evidence is clear that the kind of food my father grew up eating quickly makes you feel full. But the kind of food I grew up eating, much of which is made in factories, often with artificial chemicals, left me feeling empty and as if I had a hole in my stomach

In a recent study of what American children eat, ultraprocessed food was found to make up 67 percent of their daily diet. This kind of food makes you want to eat more and more. Satiety comes late, if at all.

After he moved in 2000 to the United States in his 20s, he gained 30 pounds in two years. He began to wonder if the American diet has some kind of strange effect on our brains and our cravings, so he designed an experiment to test it.

He and his colleague Paul Johnson raised a group of rats in a cage and gave them an abundant supply of healthy, balanced rat chow made out of the kind of food rats had been eating for a very long time. The rats would eat it when they were hungry, and then they seemed to feel sated and stopped. They did not become fat.

then Dr. Kenny and his colleague exposed the rats to an American diet: fried bacon, Snickers bars, cheesecake and other treats. They went crazy for it. The rats would hurl themselves into the cheesecake, gorge themselves and emerge with their faces and whiskers totally slicked with it. They quickly lost almost all interest in the healthy food, and the restraint they used to show around healthy food disappeared. Within six weeks, their obesity rates soared.

They took all the processed food away and gave the rats their old healthy diet. Dr. Kenny was confident that they would eat more of it, proving that processed food had expanded their appetites. But something stranger happened. It was as though the rats no longer recognized healthy food as food at all, and they barely ate it. Only when they were starving did they reluctantly start to consume it again.

Drugs like Ozempic work precisely by making us feel full.

processed and ultraprocessed food create a raging hole of hunger, and these treatments can repair that hole

the drugs are “an artificial solution to an artificial problem.”

Yet we have reacted to this crisis largely caused by the food industry as if it were caused only by individual moral dereliction

Why do we turn our anger inward and not outward at the main cause of the crisis? And by extension, why do we seek to shame people taking Ozempic but not those who, say, take drugs to lower their blood pressure?

The first is the belief that obesity is a sin.

The second idea is that we are all in a competition when it comes to weight. Ours is a society full of people fighting against the forces in our food that are making us fatter.

Looked at in this way, people on Ozempic can resemble cyclists like Lance Armstrong who used performance-enhancing drugs.

We can’t find our way to a sane, nontoxic conversation about obesity or Ozempic until we bring these rarely spoken thoughts into the open and reckon with them

remember the competition isn’t between you and your neighbor who’s on weight-loss drugs. It’s between you and a food industry constantly designing new ways to undermine your satiety.

Reducing or reversing obesity hugely boosts health, on average: We know from years of studying bariatric surgery that it slashes the risks of cancer, heart disease and diabetes-related death. Early indications are that the new anti-obesity drugs are moving people in a similar radically healthier direction,

But these drugs may increase the risk for thyroid cancer.

Do we want these weight loss drugs to be another opportunity to tear one another down? Or do we want to realize that the food industry has profoundly altered the appetites of us all — leaving us trapped in the same cage, scrambling to find a way out?

It’s why the “bad war” of Vietnam was only escaped at the cost of betraying the South Vietnamese and making a deal with yet another monster in Beijing.

The alternative is a form of argument in which essential aspects of the world, being inconvenient to moral absolutism, simply disappear.

A “realist” foreign policy can slide from describing power to excusing depredations.

But seeing statecraft as a tragic balancing of evils is still essential, especially amid the kind of moral fervor that attends a conflict like Israel’s war in Gaza.

But in active controversies the tragic vision can seem like a cold way of looking at the world. Lean into it too hard, and you get accused of ignoring injustice or recapitulating the indifference that gave cover to past atrocities.

The difficulty is that liberal “freedom” is on offer almost nowhere in the Middle East, certainly not in Gaza under Hamas’s rule, and the most challenging “otherness of beliefs” in this situation are the beliefs that motivated the massacres of Oct. 7.

a hype around Israeli moral failures — it's not enough for a war that yields so many casualties to be unjust, if it’s wrong it must be genocide — that ends up suppressing the harsh implications of a simple call for peace.

A representative passage, from Pankaj Mishra in The London Review of Books, describes many protesters as “motivated by the simple wish to uphold the ideals that seemed so universally desirable after 1945: respect for freedom, tolerance for the otherness of beliefs and ways of life; solidarity with human suffering; and a sense of moral responsibility for the weak and persecuted.”

No doubt many campus protesters have these motivations.

The alternative articulated by, for instance, Mitt Romney — “We stand by allies, we don’t second-guess them” — is not a serious policy for a hegemon balancing its global obligations

For example, reading the apologia for pro-Palestinian protests from certain left-wing intellectuals, you have a sense of both elision and exaggeration

seem untroubled by this fact, and perfectly comfortable with supporting not just peaceful negotiation but a revolutionary struggle led by Islamist fanatics.

Which yields the moral dilemma the protests don’t acknowledge: Ending the war on the terms they want could grant a major strategic victory to the regional alliance dedicated to the murder of Israelis and their expulsion from the Middle East.

Maybe the Gaza war is unjust enough, and Israeli goals unachievable enough, that there’s no alternative to vindicating Hamas’s blood-soaked strategy

you have to be honest about what you’re endorsing: a brutal weighing-out of evils, not any sort of triumph for “universally desirable” ideals.

Then a similar point applies to supporters of the Israeli war, for whom moral considerations — the evil of Hamas, the historical suffering of the Jewish people, the special American relationship with Israel — are invoked as an argument-ender in an inflexible way

We are constantly urged to “stand with Israel” when it’s unclear if Israel knows what it’s doing.

Joe Biden’s administration is chastised for betrayal when it tries to influence Israel’s warmaking, even though the Israeli government’s decisions before and since Oct. 7 do not inspire great confidence.

Biden’s specific attempts to micromanage the conflict may be misguided or hamfisted

But it’s not misguided for America, an imperium dealing with multiplying threats, to decline to write a blank check for a war being waged without a clear plan for victory or for peace.

Another difficulty is that some instigators of the protests

In each case, you have a desire that mirrors the impulse of the left-wing intellectuals — to make foreign policy easy by condensing everything to a single moral judgment. But the problems of the world cannot be so easily reduced.

Being cold-eyed and tragic-minded does not mean abandoning morality. But it means recognizing that often nobody is simply right, no single approach is morally obvious, and no strategy is clean.

It’s dropping in developing countries, too. India surpassed China as the most populous country last year, yet its fertility is now below replacement.

“The demographic winter is coming,”

Smaller populations come with diminished global clout, raising questions in the U.S., China and Russia about their long-term standings as superpowers.

Some demographers think the world’s population could start shrinking within four decades—one of the few times it’s happened in history.

A year ago Japanese Prime Minister Fumio Kishida declared that the collapse of the country’s birthrate left it “standing on the verge of whether we can continue to function as a society.”

Had fertility stayed near 2.1, where it stood in 2007, the U.S. would have welcomed an estimated 10.6 million more babies since

In 2017, when the global fertility rate—a snapshot of how many babies a woman is expected to have over her lifetime—was 2.5, the United Nations thought it would slip to 2.4 in the late 2020s. Yet by 2021, the U.N. concluded, it was already down to 2.3—close to what demographers consider the global replacement rate of about 2.2

He has found that national birth registries are typically reporting births 10% to 20% below what the U.N. projected.

China reported 9 million births last year, 16% less than projected in the U.N.’s central scenario. In the U.S., 3.59 million babies were born last year, 4% less than the U.N. projected. In other countries, the undershoot is even larger: Egypt reported 17% fewer births last year. In 2022, Kenya reported 18% fewer.

In 2017 the U.N. projected world population, then 7.6 billion, would keep climbing to 11.2 billion in 2100. By 2022 it had lowered and brought forward the peak to 10.4 billion in the 2080s. That, too, is likely out of date

the University of Washington now thinks it will peak around 9.5 billion in 2061 then start declining. 

The falling birthrates come with huge implications for the way people live, how economies grow and the standings of the world’s superpowers.

In the U.S., a short-lived pandemic baby boomlet has reversed. The total fertility rate fell to 1.62 last year, according to provisional government figures, the lowest on record.

In 2017, when the fertility rate was 1.8, the Census Bureau projected it would converge over the long run to 2.0. It has since revised that down to 1.5. “It has snuck up on us,”

Historians refer to the decline in fertility that began in the 18th century in industrializing countries as the demographic transition. As lifespans lengthened and more children survived to adulthood, the impetus for bearing more children declined. As women became better educated and joined the workforce, they delayed marriage and childbirth, resulting in fewer children. 

Some demographers see this as part of a “second demographic transition,” a societywide reorientation toward individualism that puts less emphasis on marriage and parenthood, and makes fewer or no children more acceptable. 

In research published in 2021, the University of Maryland’s Kearney and two co-authors looked for possible explanations for the continued drop. They found that state-level differences in parental abortion notification laws, unemployment, Medicaid availability, housing costs, contraceptive usage, religiosity, child-care costs and student debt could explain almost none of the decline

“We suspect that this shift reflects broad societal changes that are hard to measure or quantify,” they conclude.

while raising children is no more expensive than before, parents’ preferences and perceived constraints have changed

“If people have a preference for spending time building a career, on leisure, relationships outside the home, that’s more likely to come in conflict with childbearing.” 

Once a low fertility cycle kicks in, it effectively resets a society’s norms and is thus hard to break, said Jackson. “The fewer children you see your colleagues and peers and neighbors having, it changes the whole social climate,”

Fertility is below replacement in India even though the country is still poor and many women don’t work—factors that usually sustain fertility.

Urbanization and the internet have given even women in traditional male-dominated villages a glimpse of societies where fewer children and a higher quality of life are the norm. “People are plugged into the global culture,

mothers and fathers, especially those that are highly educated, spend more time with their children than in the past. “The intensity of parenting is a constraint,”

Sub-Saharan Africa once appeared resistant to the global slide in fertility, but that too is changing. The share of all women of reproductive age using modern contraception grew from 17% in 2012 to 23% in 2022

Jose Rimon, a professor of public health at Johns Hopkins University, credits that to a push by national leaders in Africa which, he predicted, would drive fertility down faster than the U.N. projects. 

Mae Mariyam Thomas, 38, who lives in Mumbai and runs an audio production company, said she’s opted against having children because she never felt the tug of motherhood. She sees peers struggling to meet the right person, getting married later and, in some instances, divorcing before they have kids. At least three of her friends have frozen their eggs,

Danielle Vermeer grew up third in a family of four children on Chicago’s North Side, where her neighborhood was filled with Catholics of Italian, Irish and Polish descent and half her close friends had as many siblings as her or more.

Her Italian-American father was one of four children who produced 14 grandchildren. Now her parents have five grandchildren, including Vermeer’s two children, ages 4 and 7.

The 35-year-old, who is the co-founder of a fashion thrifting app, said that before setting out to have children, she consulted dozens of other couples and her Catholic church and read at least eight books on the subject, including one by Pope Paul VI. She and her husband settled on two as the right number.“The act of bringing a child into this world is an incredible responsibility,” she said.

Perhaps no country has been trying longer than Japan. After fertility fell to 1.5 in the early 1990s, the government rolled out a succession of plans that included parental leave and subsidized child care. Fertility kept falling.

In 2005, Kuniko Inoguchi was appointed the country’s first minister responsible for gender equality and birthrate. The main obstacle, she declared, was money: People couldn’t afford to get married or have children. Japan made hospital maternity care free and introduced a stipend paid upon birth of the child. 

Japan’s fertility rate climbed from 1.26 in 2005 to 1.45 in 2015. But then it started declining again, and in 2022 was back to 1.26.

This year, Prime Minister Fumio Kishida rolled out yet another program to increase births that extends monthly allowances to all children under 18 regardless of income, free college for families with three children, and fully paid parental leave.

noguchi, now a member of parliament’s upper house, said the constraint on would-be parents is no longer money, but time. She has pressed the government and businesses to adopt a four-day workweek

If you’re a government official or manager of a big corporation, you should not worry over questions of salary now, but that in 20 years time you will have no customers, no clients, no applicants to the Self-Defense Forces.”

Hungarian Prime Minister Viktor Orban has pushed one of Europe’s most ambitious natality agendas. Last year he expanded tax benefits for mothers so that women under the age of 30 who have a child are exempt from paying personal income tax for life. That’s on top of housing and child-care subsidies as well as generous maternity leaves. 

Hungary’s fertility rate, though still well below replacement, has risen since 2010. But the Vienna Institute of Demography attributed this primarily to women delaying childbirth because of a debt crisis that hit around 2010. Adjusted for that, fertility has risen only slightly, it concluded.

The usual prescription in advanced countries is more immigration, but that has two problems.

With no reversal in birthrates in sight, the attendant economic pressures are intensifying. Since the pandemic, labor shortages have become endemic throughout developed countries. That will only worsen in coming years as the postcrisis fall in birthrates yields an ever-shrinking inflow of young workers, placing more strain on healthcare and retirement systems.

worsening demographics could make this a second consecutive “lost decade” for global economic growth.

The Institute for Health Metrics and Evaluation found little evidence that pronatalist policies lead to sustained rebounds in fertility. A woman may get pregnant sooner to capture a baby bonus, researchers say, but likely won’t have more kids over the course of her lifetime.

As more countries confront stagnant population, immigration between them is a zero-sum gam

Historically, host countries have sought skilled migrants who enter through formal, legal channels, but recent inflows have been predominantly unskilled migrants often entering illegally and claiming asylum.

High levels of immigration have also historically aroused political resistance,

Many of the leaders keenest to raise birthrates are most resistant to immigratio

As birthrates fall, more regions and communities experience depopulation, with consequences ranging from closed schools to stagnant property values. Less selective colleges will soon struggle to fill classrooms because of the plunge in birthrates that began in 2007, said Fernández-Villaverde. Vance said rural hospitals can’t stay open because of the falling local population.

An economy with fewer children will struggle to finance pensions and healthcare for growing ranks of elderly. South Korea’s national pension fund, one of the world’s largest, is on track to be depleted by 2055

There’s been little public pressure to act, said Sok Chul Hong, an economist at Seoul National University. “The elderly are not very interested in pension reform, and the youth are apathetic towards politics,” he said. “It is truly an ironic situation.”

James Baldwin compared it to the talking drum, used to convey messages across distances that the human voice can’t travel: “It is a music which creates, as what we call History cannot sum up the courage to do, the response to that absolutely universal question: Who am I? What am I doing here?”

it’s difficult not to read “James” as a corrective of Everett’s previous works, if not of its source material. For Jim’s predecessors, freedom requires abstraction: the problem is other people. But Jim’s understanding of freedom is literal. He knows that his happiness depends upon the emancipation of his family. At first, he wields a pencil, but then he exchanges it for a gun.
