Things that were long big fun now overwhelm, exhaust and annoy. The holiday season is an extended exercise in excess and loud, often sleazy sweaters.

Which means it is nothing of the sort. This is the drag equivalent of fun and suggests that fun is done.

Adults assiduously record themselves appearing to have something masquerading as “fun,” a fusillade of Coachellic micro social aggressions unleashed on multiple social media platforms. Look at me having so much FUN!

“I feel like I should be having more fun than I’m actually having,” says Alyssa Alvarez, a social media marketing manager and DJ in Detroit, expressing a sentiment that many share. “There are expectations of what I want people to believe that my life is like rather than what my life is actually like.”

Weddings have morphed into multistage stress extravaganzas while doubling as express paths to insolvency: destination proposals for the whole family, destination bachelorette and bachelor blowouts, destination weddings in remote barns with limited lodging, something called a “buddymoon” (bring the gang!) and planners to help facilitate the same custom cocktailsness of it all.

What could be a greater cause for joy or more natural than having a baby? Apparently, not much these days. Impending parenthood is overthought and over-apped, incorporating more savings-draining events that didn’t exist a few decades ago: babymoons and lethal, fire-inducing, gender-reveal gatherings and baby showers so over-the-top as to shame weddings.

Retirements must be purposeful. Also, occasions for an acute identity crisis. You need to have a plan, a mission, a coach, a packed color-coded grid of daily activities in a culture where our jobs are our identities, our worth tied to employment.

Vacations are overscheduled with too many activities, FOMO on steroids, a paradox of choice-inducing decision fatigue, so much so that people return home exhausted and in need of another one.

“The world is so much less about human connection,” says Amanda Richards, 34, who works in casting in Los Angeles and is a graduate of Cudworth’s course. “We do more things virtually. People are more isolated. And there’s all this toxic positivity to convince people of how happy you are.”

For eons, early adulthood was considered an age of peak fun. Now, according to several studies, it’s a protracted state of anxiety and depression.

Because there is now a coach for everything, Alvarez hired the “party coach” Evan Cudworth, taking his $497 course this fall on how to pursue “intentional fun.” (It now costs $555.)

Instead of this being the most wonderful time of the year, we battle holiday fatigue, relentless beseeching for our money and, if Fox News is to be believed, a war on Christmas that is nearing its third decade.

Blame it on technological advances that tether us to work without cessation

Blame it on the pandemic, which exacerbated so much while delivering Zoomageddon.

Blame it on 2004, with the advent of Facebook, which led to Twitter (okay, X), Instagram, Threads, TikTok and who-knows-what lurking in the ether.

Blame it again on 2004 and the introduction of FOMO, our dread of missing out, broadcast through multiple social media spigots

“So many people are retreating into their phones, into anxiety,” says Cudworth, 37, from Chicago. “I’m helping people rediscover what fun means to them.”

His mandate is redefining fun: cutting back on bingeing screen time, eradicating envy scrolling, getting outside, moving, dancing. “With technology, we don’t allow ourselves to be present. You’re always thinking ‘something is better around the corner,’” Cudworth says, the now squandered in pursuit of the future.

Blame it on an American culture that values work, productivity, power, wealth, status and more work over leisure

ow do Americans spend their leisure hours when they might be having fun with others, making those vital in-person connections? Watching television, our favorite free time and “sports activity” (yes, that’s how it’s classified), according to the Bureau of Labor Statistics, an average of 2.8 hours daily.

“That’s way more television than you really need. We put play on the back burner,” says Pat Rumbaugh, 65, of Takoma Park, Md. She’s “The Play Lady,” who organizes unorganized play for adults

Catherine Price, the author of “The Power of Fun: How to Feel Alive Again,” believes “we’re totally misdoing leisure” and “not leaving any room for spontaneity.”

To Price, True Fun is the confluence of connection (other people, nature), playfulness (lightheartedness, freedom) and flow (being fully engaged, present), which is not as challenging as it sounds. “You can have fun in any context. Playfulness is about an attitude,”

Back in the day, co-workers were friends. (Sometimes, more.) After hours, they gathered for drinks, played softball. Today, because of email, Slack and remote work, offices are half empty and far quieter than libraries.

“We go to work and there’s no sense of connection and camaraderie,” says Davis, who was long employed by his city’s department of parks and recreation. “People feel emotionally disconnected. Healthy conversations are the precursor of fun. We’ve lost the art of communication. Our spirit comes home with us. If you don’t communicate at work, what are you coming home with?”

Curley, a lawyer and former Army colonel, oversees the police officers at the building. She is best known to the public as the person who chants, "Oyez! Oyez! Oyez!" at the beginning of the justices' oral argument sessions. The marshal's office would not normally examine the details of cell phone data or engage in a broad-scale investigation of personnel.The investigation comes at the busiest time in the court's annual term, when relations among the justices are already taut. Assisted by their law clerks, the justices are pressing toward late June deadlines, trying to resolve differences in the toughest cases, all with new pressures and public scrutiny.

The draft opinion in the case of Dobbs v. Jackson Women's Health Organization was written by Justice Samuel Alito and appeared to have a five-justice majority to completely reverse the 1973 Roe v. Wade decision. That landmark ruling made abortion legal nationwide and buttressed other privacy interests not expressly stated in the Constitution. Some law professors have warned that if Roe is reversed, the Supreme Court's 2015 decision declaring a constitutional right to same-sex marriage could be in jeopardy.

As the justices continue their secret negotiations, the scrutiny of the law clerks is heating up.The clerks have been the subject of much of the outside speculation over who might have disclosed the draft, but they are not the only insiders who had access. Alito's opinion, labeled a first draft and dated February 10, would have been circulated to the nine justices, their clerks, and key staffers within each justice's chambers and select administrative offices.

Cell phones, of course, hold an enormous amount of information, related to personal interactions, involving all manner of content, texts and images, as well as apps used. It is uncertain whether details linked only to calls would be sought or whether a broader retrieval would occur.

Court officials are secretive even in normal times. No progress reports related to the leak investigation have been made public, and it is not clear whether any report from the probe will ever be released.

WeRide has a valuation of $4.4 billion, according to CB Insights, with backers such as Nissan and Qiming Venture Partners. WeRide operates robotaxis and robobuses in parts of the southern city of Guangzhou, where it’s also testing self-driving street sweepers.

“Because Bosch is in charge of integration, we have to really spend 120% of our time to help Bosch with the integration and adaptation work,” Han said. WeRide has yet to go public.

picks for autonomous driving include ArcSoft and Desay SV.An outsourcing business model in China gives independent software vendors more opportunities than in the United States, where software is developed in-house at companies like Tesla, the analysts said. Beijing also plans to have L3 vehicles in mass production by 2025.“Auto OEMs are investing significantly in car software/digitalization to 2025, targeting US$20bn+ of obtainable software revenue by decade-end,” the Goldman analysts wrote in mid-March.

They estimate that for every car, the value of software within will rise from $202 each for L0 cars to $4,957 for L4 cars in 2030. For comparison, the battery component costs at least $5,000 today. By that calculation, the market for advanced driver assistance systems and autonomous driving software is set to surge from $2.4 billion in 2021 to $70 billion in 2030 — with China accounting for about a third, the analysts predict.

it is palpable: what happens in the UK and Europe doesn’t stay in the UK and Europe.

In the past couple of weeks, the UK and several countries in Europe, including Germany, France and Switzerland, are experiencing a new wave.

This is the sixth warning from the UK and Europe to the United States.

Wastewater surveillance is relatively sparse in the United States, but 15% of the 410 sites where it was conducted between 24 February to 10 March 2022 showed a greater than 1000% increase compared with the prior 15-day period

Now we are at a point with very low vaccination and booster rates, only 64% of the populations has had two shots, and 29% three shots. That puts the United States at 65th and 70th in the world ranking of countries, respectively.

Rather than focusing on what precisely is driving the new wave, the imperative is to drive some preventive action.

As with the first five warnings from the UK and Europe, the United States did not take heed. Instead of proactively gearing up with non-pharmaceutical interventions (masks, quality of masks, distancing, air filtration, ventilation, aggressive testing, etc.), it just reacted to the surges when they were manifest.

the BA.2 variant is gaining steam in the United States and is now accounting for more than 30% of new cases.

Not only is there a gaping hole in our immunity wall, but the $58bn budget of the American Pandemic Prepared Plan (AP3) advanced by the White House to comprehensively address the deficiencies was gutted by the Senate, reduced to $2bn, now threatening to cancel the order of more than 9.2m Paxlovid pills, the Test-to Treat program announced at the State of the Union address, along with better data, wastewater surveillance, efforts to develop a pan-coronavirus vaccine, research on long Covid, and many other critical public health measures.

We haven’t even seen a new, major variant yet, but there are too many reasons to believe that is likely in the months ahead, owing to extensive animal reservoirs and documented cases of spillover to humans, a large number of immunocompromised people in whom the virus can undergo accelerated evolution, rare but increasingly seen co-infections, and lack of containment of the virus globally.

Unfortunately, we have a mindset that the pandemic is over, which couldn’t be further than the truth

dd to all this is what is happening in China, which has fully relied on a zero-Covid policy, resulting in very little natural immunity, and vaccines that have weak efficacy against Omicron

Most religious faiths instruct us to welcome the strangers we encounter, and there’s good reason for this. If we engaged only with the people we knew, our world would be small.

That leap of faith toward the unknown other is what allows us to grow beyond the family unit, tribe or nation. Everyone you converse with who is not a biological relative — your best friend, neighbor, lover, spouse or even that chatty taxi driver from last weekend — was a stranger before you spoke to that person. Anytime we ignore strangers in our vicinity, whether because of fear, bigotry or the everyday convenience and efficiency of digital technology, we weaken that contract.

the small, transactional relationships we create by talking to strangers are important pillars of our social and emotional well-being.

Far from random human inconveniences, strangers are actually one of the richest and most important resources we have. They connect us to the community, teach us empathy, build civility and are full of surprise and potentially wonder.

“We have all these kinds of people who populate our lives, who we aren’t that close to and we don’t share our deepest, darkest secrets with,” said Dr. Sandstrom, who forces herself to speak to strangers every day, despite identifying as an introvert. “But they form this tapestry that when we’re not there, our life feels kind of empty.”

A study published last fall showed that despite our fears of awkwardness, deep, meaningful conversations with strangers are not only easier than expected but also left participants feeling better about themselves.

In some ways, our recent aversion to strangers is a byproduct of technological evolution. Sure, newspapers and magazines, cassette players and televisions were all potential distractions, but none of them fully normalized ignoring other people in the way that smartphones have. E-commerce sites and third-party restaurant delivery apps incentivize us against entering stores and restaurants filled with strangers

Then came the pandemic, and suddenly, each physical encounter with a stranger carried the potential of death. We were ordered to stay home, avoid public spaces and to speak only within our trusted bubbles.

that would be on par with what we experience with flu viruses, which scientists estimate hit us about every two to five years, less often in adulthood. It also matches up well with the documented cadence of the four other coronaviruses that seasonally trouble humans, and cause common colds.

For now, every infection, and every subsequent reinfection, remains a toss of the dice. “Really, it’s a gamble,” says Ziyad Al-Aly, a clinical epidemiologist and long-COVID researcher at Washington University in St. Louis. Vaccination and infection-induced immunity may load the dice against landing on severe disease, but that danger will never go away completely, and scientists don’t yet know what happens to people who contract “mild” COVID over and over again

Or maybe not. This virus seems capable of tangling into just about every tissue in the body, affecting organs such as the heart, brain, liver, kidneys, and gut; it has already claimed the lives of millions, while saddling countless others with symptoms that can linger for months or years.

considering our current baseline, “less dangerous” could still be terrible—and it’s not clear exactly where we’re headed. When it comes to reinfection, we “just don’t know enough,”

Perhaps, as several experts have posited since the pandemic’s early days, SARS-CoV-2 will just become the fifth cold-causing coronavirus.

Bodies, wised up to the virus’s quirks, can now react more quickly, clobbering it with sharper and speedier strikes.

Future versions of SARS-CoV-2 could continue to shape-shift out of existing antibodies’ reach, as coronaviruses often do. But the body is flush with other fighters that are much tougher to bamboozle—among them, B cells and T cells that can quash a growing infection before it spirals out of control

Those protections tend to build iteratively, as people see pathogens or vaccines more often. People vaccinated three times over, for instance, seem especially well equipped to duke it out with all sorts of SARS-CoV-2 variants, including Omicron and its offshoots.

promising patterns: Second infections and post-vaccination infections “are significantly less severe,” she told me, sometimes to the point where people don’t notice them at all

A third or fourth bout might be more muted still; the burden of individual diseases may be headed toward an asymptote of mildness that holds for many years

Gordon and Swartz are both hopeful that the slow accumulation of immunity will also slash people’s chances of developing long COVID.

Immunity, though, is neither binary nor permanent. Even if SARS-CoV-2’s assaults are blunted over time, there are no guarantees about the degree to which that happens, or how long it lasts.

A slew of factors could end up weighting the dice toward severe disease—among them, a person’s genetics, age, underlying medical conditions, health-care access, and frequency or magnitude of exposure to the virus.

for everyone else, no amount of viral dampening can totally eliminate the chance, however small it may be, of getting very sick.

Long COVID, too, might remain a possibility with every discrete bout of illness. Or maybe the effects of a slow-but-steady trickle of minor, fast-resolving infections would sum together, and bring about the condition.

Every time the body’s defenses are engaged, it “takes a lot of energy, and causes tissue damage,” Thomas told me. Should that become a near-constant barrage, “that’s probably not great for you.”

Bodies are resilient, especially when they’re offered time to rest, and she doubts that reinfection with a typically ephemeral virus such as SARS-CoV-2 would cause mounting damage. “The cumulative effect is more likely to be protective than detrimental,” she said, because of the immunity that’s laid down each time.

people who have caught the virus twice or thrice may be more likely to become long-haulers than those who have had it just once.

Some other microbes, when they reinvade us, can fire up the immune system in unhelpful ways, driving bad bouts of inflammation that burn through the body, or duping certain defensive molecules into aiding, rather than blocking, the virus’s siege. Researchers don’t think SARS-CoV-2 will do the same. But this pathogen is “much more formidable than even someone working on coronaviruses would have expected,

Seasonal encounters with pathogens other than SARS-CoV-2 don’t often worry us—but perhaps that’s because we’re still working to understand their toll. “Have we been underestimating long-term consequences from other repeat infections?” Thomas said. “The answer is probably, almost certainly, yes.”

the rhythm of reinfection isn’t just about the durability of immunity or the pace of viral evolution. It’s also about our actions and policies, and whether they allow the pathogen to transmit and evolve. Strategies to avoid infection—to make it as infrequent as possible, for as many people as possible—remain options, in the form of vaccination, masking, ventilation, paid sick leave, and more.

“There are still very good reasons” to keep exposures few and far between, Landon, of the University of Chicago, told me. Putting off reinfection creates fewer opportunities for harm: The dice are less likely to land on severe disease (or chronic illness) when they’re rolled less often overall. It also buys us time to enhance our understanding of the virus, and improve our tools to fight it.

The outlooks of the experts I spoke with spanned the range from optimism to pessimism, though all agreed that uncertainty loomed. Until we know more, none were keen to gamble with the virus—or with their own health. Any reinfection will likely still pose a threat, “even if it’s not the worst-case scenario,” Abdool Karim told me. “I wouldn’t want to put myself in that position.”

The second letter was signed by more than 100 LGBTQ+ and civil rights groups, including Glaad and the Human Rights Campaign. It expressed support for the contributor letter and accused the Times of platforming “fringe theories” and “dangerous inaccuracies”. It noted that while the Times has produced responsible coverage of trans people, “those articles are not getting front-page placement or sent to app users via push notification like the irresponsible pieces are”. And it observed that rightwing politicians have been using the Times’s coverage of trans issues to justify criminalizing gender-affirming care.

Charlie Stadtlander, the Times’ director of external communication, put out a statement stating that the organization pursues “independent reporting on transgender issues that include profiling groundbreakers in the movement, challenges and prejudice faced by the community, and how society is grappling with debates about care”. While that was all very diplomatic, the executive editor, Joe Kahn, and opinion editor, Kathleen Kingsbury, sent around a rather more pointed newsroom memo condemning the letters on Thursday.

“It is not unusual for outside groups to critique our coverage or to rally supporters to seek to influence our journalism,” Kahn wrote in the memo. “In this case, however, members of our staff and contributors to The Times joined the effort … We do not welcome, and will not tolerate, participation by Times journalists in protests organized by advocacy groups or attacks on colleagues on social media and other public forums.”

Here’s the thing: there is no clear-cut line between advocacy and journalism. All media organizations have a perspective about the world and filter their output (which will, of course, strive to be fairly reported) through that perspective. To pretend otherwise is dishonest. Like it or not, the Times is involved in advocacy. It just needs to step back for a moment and think about who it’s advocating for.

They tend to read each assignment two or three times before coming to class and take notes as well. Some of them have been incarcerated for 20 or 30 years and have been reading books all that time. They would hold their own in any graduate seminar. That they have had rough experiences out in the real world means they are less liable to fall prey to facile ideologies. A large proportion of them are black and Latino, and while they may not like David Hume’s or Thomas Jefferson’s ideas on race, they want to read those authors anyway. They want, in short, to be a part of the centuries-long conversation that makes up our civilization

My students there, enrolled in a for-credit college program, provide a sharp contrast with contemporary undergraduates. These men are highly motivated and hard-working

Never have I been more grateful to teach where I do: at a men’s maximum-security priso

Best of all from my selfish point of view as an educator, these students have no access to cellphones or the internet

they have retained their attention spans, while those of modern college students have been destroyed by their dependence on smartphones

My friends who teach at Harvard tell me administrators have advised them to change topics or activities several times in each class meeting because the students simply can’t focus for that long.

My students at the prison sit through a 2½-hour class without any loss of focus. They don’t yawn or take bathroom breaks

I have taught classes on the Enlightenment, the Renaissance, Romanticism, George Orwell, South Asian fiction. We’ve done seminars on Adam Smith and Alexis de Tocqueville. Together we have read Montaigne, Rousseau, Keats, Erasmus, Locke, Montesquieu, Wollstonecraft, Byron, Goethe, Petrarch, Rabelais, Saadat Hasan Manto, Rohinton Mistry

We encourage them to treat different societies in history as experiments in time travel, where they try to understand the mores of particular eras as though from the inside. They are very open to that approach, unlike university students, who tend see the past only as one long undifferentiated era of grievous unenlightenment: not just one damn thing after another, but one damn oppressive thing after another.

Like students at elite institutions, most of my incarcerated scholars are politically liberal. Unlike them, many are religious, and that proves surprisingly enriching in studying these authors

My hours at the prison are rich in such moments. In many ways, it is the Platonic ideal of teaching, what teaching once was. No faculty meetings, no soul-deadening committee work, no bloated and overbearing administration. No electronics, no students whining about grades.

Quite a few of our students are serving life sentences and will never be able to make use of their hard-won college credits

No student debt, no ideological intolerance, no religious tests—whoops, I mean mandatory “diversity” statements.

And in our courteous, laughter-filled classroom there is none of the “toxic environment” that my friends in the academy complain about, and that I experienced during my own college teaching career.

If prison inmates, many of whom have committed violent crimes, can pay close attention for a couple of hours, put aside their political and personal differences, support one another’s academic efforts, write eloquent essays without the aid of technology and get through a school year without cheating, is it too much to ask university students to do the same?

Or ask professors to try to create an atmosphere where these habits can prevail

On March 11, YouTube’s parent company Google announced that it would block Russian state-backed media globally, including within Russia. The policy was an expansion of an earlier announcement that these channels would be blocked within the European Union. “Our Community Guidelines prohibit content denying, minimizing or trivializing well-documented violent events, and we remove content about Russia’s invasion in Ukraine that violates this policy,” Google said in a statement. “In line with that, effective immediately, we are also blocking YouTube channels associated with Russian state-funded media, globally.”

That could leave many millions of Russians cut off from independent news and content shared by opposition activists like Navalny’s team. (It would also effectively delete 75 million YouTube users, or some 4% of the platform’s global total—representing a small but still-significant portion of Google’s overall profits.)

Today, YouTube remains the most significant way for tens of millions of ordinary Russians to receive largely uncensored information from the outside world.

Part of the reason for YouTube’s survival amid the crackdown is its popularity, experts say. “YouTube is by far and away the most popular social media platform in Russia,” says Justin Sherman, a non-resident fellow at the Atlantic Council’s cyber statecraft initiative. The platform is even more popular than VK, the Russian-owned answer to Facebook.

Still, Sherman says the situation is volatile, with Russia now more likely than ever before to ban YouTube. For an authoritarian government like Russia’s, “part of the decision to allow a foreign platform in your country is that you get to use it to spread propaganda and disinformation, even if people use it to spread truth and organize against you,” he says. “If you start losing the ability to spread misinformation and propaganda, but people can still use it to spread truth and organize, then all of a sudden, you start wondering why you’re allowing that platform in your country in the first place.” YouTube did not respond to a request for comment.

On the same day as Navalny’s channel posted the video about Matviyenko, elsewhere on YouTube a very different spectacle was playing out. In a video posted to the channel of the Kremlin-funded media outlet RT, (formerly known as Russia Today,) a commentator dismissed evidence of Russian bombings of Ukrainian cities. She blamed “special forces of NATO countries” for allegedly faking images of bombed-out Ukrainian schools, kindergartens and other buildings.

“YouTube has, over the years, been a really important place for spreading Russian propaganda,” Donovan said in an interview with TIME days before YouTube banned Russian state-backed media.

In July 2021, the Russian government passed a law that would require foreign tech companies with more than 500,000 users to open a local office within Russia. (A similar law passed previously in India had been used by the government there to pressure tech companies to take down opposition accounts and posts critical of the government, by threatening employees with arrest.)

The heightened risk to free expression in Russia Experts say that Russia’s ongoing crackdown on social media platforms heralds a significant shift in the shape of the Russian internet—and a potential end to the era where the Kremlin tolerated largely free expression on YouTube in return for access to a tool that allowed it to spread disinformation far and wide.

“AI is the next revolution and there is no going back,”

“There is an enormous demand for people who are tech-savvy and who will be the first adopters, who will be the first to figure out what opportunities these technologies open up,”

“Every month there are hundreds more job postings mentioning generative AI,”

“The way things have been done in the past aren’t necessarily the way they need to be done today,” he said, adding that workers and employers should invest in retraining and upskilling where possible.

that transformation is already taking shape, and workers can find ways to use the ChatGPT and other new technology to free them from boring work.

The jobs of the future will require a mind-set shift for employees, several executives said. Rather than viewing generative AI and other machine-learning software as a threat, workers should embrace new technology as a way to free them from less-rewarding work and augment their strengths.

“This is a huge opportunity to advance a lot of professions—allow people to do work that’s, frankly, more stimulating.”

For the hotel chain, that could look like using AI to determine which brand of wine a guest likes, and adjusting recommendations accordingly.

United Airlines Holdings Inc., aims to use AI to do transactions that shouldn’t require a human, such as placing someone in an aisle or window seat depending on their preference, or suggesting a different flight for someone trying to book a tight connection, said Kate Gebo, executive vice president of human resources and labor relations. That leaves employees free to have more complex interactions with customers

services intended to help customers solve emotional problems require solutions a machine can’t provide.

“AI is not sentient. It can’t be emotional. And that is the kind of accountability and reciprocity that is needed…for people to have the outcomes that we’re hoping to provide,”

“Certain business processes could be enhanced,” said Carmen Orr, Yelp’s chief people officer, adding that there are plenty of concerns, too. “We don’t want it for high human-touch things.”

An aperiodic tiling displays no such “translational symmetry,” and mathematicians have long sought a single shape that could tile the plane in such a fashion. This is known as the einstein problem.

“I’m always messing about and experimenting with shapes,” said Mr. Smith, 64, who worked as a printing technician, among other jobs, and retired early. Although he enjoyed math in high school, he didn’t excel at it, he said. But he has long been “obsessively intrigued” by the einstein problem.

now a new paper — by Mr. Smith and three co-authors with mathematical and computational expertise — proves Mr. Smith’s discovery true. The researchers called their einstein “the hat,

“The most significant aspect for me is that the tiling does not clearly fall into any of the familiar classes of structures that we understand.”

black and white squares also can make weird nonperiodic patterns, in addition to the familiar, periodic checkerboard pattern. “It’s really pretty trivial to be able to make weird and interesting patterns,” he said. The magic of the two Penrose tiles is that they make only nonperiodic patterns — that’s all they can do.“But then the Holy Grail was, could you do with one — one tile?” Dr. Goodman-Strauss said.

Sir Roger found the proofs “very complicated.” Nonetheless, he was “extremely intrigued” by the einstein, he said: “It’s a really good shape, strikingly simple.”

When in November he found a tile that seemed to fill the plane without a repeating pattern, he emailed Craig Kaplan, a co-author and a computer scientist at the University of Waterloo.

The simplicity came honestly. Mr. Smith’s investigations were mostly by hand; one of his co-authors described him as an “imaginative tinkerer.”

“It was clear that something unusual was happening with this shape,” Dr. Kaplan said. Taking a computational approach that built on previous research, his algorithm generated larger and larger swaths of hat tiles. “There didn’t seem to be any limit to how large a blob of tiles the software could construct,”

The first step, Dr. Kaplan said, was to “define a set of four ‘metatiles,’ simple shapes that stand in for small groupings of one, two, or four hats.” The metatiles assemble into four larger shapes that behave similarly. This assembly, from metatiles to supertiles to supersupertiles, ad infinitum, covered “larger and larger mathematical ‘floors’ with copies of the hat,” Dr. Kaplan said. “We then show that this sort of hierarchical assembly is essentially the only way to tile the plane with hats, which turns out to be enough to show that it can never tile periodically.”

some might wonder whether this is a two-tile, not one-tile, set of aperiodic monotiles.

Dr. Goodman-Strauss had raised this subtlety on a tiling listserv: “Is there one hat or two?” The consensus was that a monotile counts as such even using its reflection. That leaves an open question, Dr. Berger said: Is there an einstein that will do the job without reflection?

“the hat” was not a new geometric invention. It is a polykite — it consists of eight kites. (Take a hexagon and draw three lines, connecting the center of each side to the center of its opposite side; the six shapes that result are kites.)

“It’s likely that others have contemplated this hat shape in the past, just not in a context where they proceeded to investigate its tiling properties,” Dr. Kaplan said. “I like to think that it was hiding in plain sight.”

Incredibly, Mr. Smith later found a second einstein. He called it “the turtle” — a polykite made of not eight kites but 10. It was “uncanny,” Dr. Kaplan said. He recalled feeling panicked; he was already “neck deep in the hat.”

Dr. Myers, who had done similar computations, promptly discovered a profound connection between the hat and the turtle. And he discerned that, in fact, there was an entire family of related einsteins — a continuous, uncountable infinity of shapes that morph one to the next.

this einstein family motivated the second proof, which offers a new tool for proving aperiodicity. The math seemed “too good to be true,” Dr. Myers said in an email. “I wasn’t expecting such a different approach to proving aperiodicity — but everything seemed to hold together as I wrote up the details.”

Mr. Smith was amazed to see the research paper come together. “I was no help, to be honest.” He appreciated the illustrations, he said: “I’m more of a pictures person.”

The Tesla Inc. CEO tweeted in February that OpenAI had been founded as an open-source nonprofit “to serve as a counterweight to Google, but now it has become a closed source, maximum-profit company effectively controlled by Microsoft. Not what I intended at all.”

Backers say his brand of social-minded capitalism makes him the ideal person to lead OpenAI. Others, including some who’ve worked for him, say he’s too commercially minded and immersed in Silicon Valley thinking to lead a technological revolution that is already reshaping business and social life. 

In the long run, he said, he wants to set up a global governance structure that would oversee decisions about the future of AI and gradually reduce the power OpenAI’s executive team has over its technology. 

OpenAI researchers soon concluded that the most promising path to achieve artificial general intelligence rested in large language models, or computer programs that mimic the way humans read and write. Such models were trained on large volumes of text and required a massive amount of computing power that OpenAI wasn’t equipped to fund as a nonprofit, according to Mr. Altman. 

In its founding charter, OpenAI pledged to abandon its research efforts if another project came close to building AGI before it did. The goal, the company said, was to avoid a race toward building dangerous AI systems fueled by competition and instead prioritize the safety of humanity.

While running Y Combinator, Mr. Altman began to nurse a growing fear that large research labs like DeepMind, purchased by Google in 2014, were creating potentially dangerous AI technologies outside the public eye. Mr. Musk has voiced similar concerns of a dystopian world controlled by powerful AI machines. 

Messrs. Altman and Musk decided it was time to start their own lab. Both were part of a group that pledged $1 billion to the nonprofit, OpenAI Inc. 

Mr. Altman said he doesn’t necessarily need to be first to develop artificial general intelligence, a world long imagined by researchers and science-fiction writers where software isn’t just good at one specific task like generating text or images but can understand and learn as well or better than a human can. He instead said OpenAI’s ultimate mission is to build AGI, as it’s called, safely.

“We didn’t have a visceral sense of just how expensive this project was going to be,” he said. “We still don’t.”

Tensions also grew with Mr. Musk, who became frustrated with the slow progress and pushed for more control over the organization, people familiar with the matter said. 

OpenAI executives ended up reviving an unusual idea that had been floated earlier in the company’s history: creating a for-profit arm, OpenAI LP, that would report to the nonprofit parent. 

Reid Hoffman, a LinkedIn co-founder who advised OpenAI at the time and later served on the board, said the idea was to attract investors eager to make money from the commercial release of some OpenAI technology, accelerating OpenAI’s progress

“You want to be there first and you want to be setting the norms,” he said. “That’s part of the reason why speed is a moral and ethical thing here.”

The decision further alienated Mr. Musk, the people familiar with the matter said. He parted ways with OpenAI in February 2018. 

Mr. Musk announced his departure in a company all-hands, former employees who attended the meeting said. Mr. Musk explained that he thought he had a better chance at creating artificial general intelligence through Tesla, where he had access to greater resources, they said.

OpenAI said that it received about $130 million in contributions from the initial $1 billion pledge, but that further donations were no longer needed after the for-profit’s creation. Mr. Musk has tweeted that he donated around $100 million to OpenAI. 

Mr. Musk’s departure marked a turning point. Later that year, OpenAI leaders told employees that Mr. Altman was set to lead the company. He formally became CEO and helped complete the creation of the for-profit subsidiary in early 2019.

A young researcher questioned whether Mr. Musk had thought through the safety implications, the former employees said. Mr. Musk grew visibly frustrated and called the intern a “jackass,” leaving employees stunned, they said. It was the last time many of them would see Mr. Musk in person.  

In the meantime, Mr. Altman began hunting for investors. His break came at Allen & Co.’s annual conference in Sun Valley, Idaho in the summer of 2018, where he bumped into Satya Nadella, the Microsoft CEO, on a stairwell and pitched him on OpenAI. Mr. Nadella said he was intrigued. The conversations picked up that winter.

“I remember coming back to the team after and I was like, this is the only partner,” Mr. Altman said. “They get the safety stuff, they get artificial general intelligence. They have the capital, they have the ability to run the compute.”   

Mr. Altman disagreed. “The unusual thing about Microsoft as a partner is that it let us keep all the tenets that we think are important to our mission,” he said, including profit caps and the commitment to assist another project if it got to AGI first. 

Some employees still saw the deal as a Faustian bargain. 

OpenAI’s lead safety researcher, Dario Amodei, and his lieutenants feared the deal would allow Microsoft to sell products using powerful OpenAI technology before it was put through enough safety testing,

They felt that OpenAI’s technology was far from ready for a large release—let alone with one of the world’s largest software companies—worrying it could malfunction or be misused for harm in ways they couldn’t predict.  

Mr. Amodei also worried the deal would tether OpenAI’s ship to just one company—Microsoft—making it more difficult for OpenAI to stay true to its founding charter’s commitment to assist another project if it got to AGI first, the former employees said.

Microsoft initially invested $1 billion in OpenAI. While the deal gave OpenAI its needed money, it came with a hitch: exclusivity. OpenAI agreed to only use Microsoft’s giant computer servers, via its Azure cloud service, to train its AI models, and to give the tech giant the sole right to license OpenAI’s technology for future products.

In a recent investment deck, Anthropic said it was “committed to large-scale commercialization” to achieve the creation of safe AGI, and that it “fully committed” to a commercial approach in September. The company was founded as an AI safety and research company and said at the time that it might look to create commercial value from its products. 

Mr. Altman “has presided over a 180-degree pivot that seems to me to be only giving lip service to concern for humanity,” he said. 

“The deal completely undermines those tenets to which they secured nonprofit status,” said Gary Marcus, an emeritus professor of psychology and neural science at New York University who co-founded a machine-learning company

The cash turbocharged OpenAI’s progress, giving researchers access to the computing power needed to improve large language models, which were trained on billions of pages of publicly available text. OpenAI soon developed a more powerful language model called GPT-3 and then sold developers access to the technology in June 2020 through packaged lines of code known as application program interfaces, or APIs. 

Mr. Altman and Mr. Amodei clashed again over the release of the API, former employees said. Mr. Amodei wanted a more limited and staged release of the product to help reduce publicity and allow the safety team to conduct more testing on a smaller group of users, former employees said. 

Mr. Amodei left the company a few months later along with several others to found a rival AI lab called Anthropic. “They had a different opinion about how to best get to safe AGI than we did,” Mr. Altman said.

Anthropic has since received more than $300 million from Google this year and released its own AI chatbot called Claude in March, which is also available to developers through an API. 

Mr. Altman shared the contract with employees as it was being negotiated, hosting all-hands and office hours to allay concerns that the partnership contradicted OpenAI’s initial pledge to develop artificial intelligence outside the corporate world, the former employees said. 

In the three years after the initial deal, Microsoft invested a total of $3 billion in OpenAI, according to investor documents. 

More than one million users signed up for ChatGPT within five days of its November release, a speed that surprised even Mr. Altman. It followed the company’s introduction of DALL-E 2, which can generate sophisticated images from text prompts.

By February, it had reached 100 million users, according to analysts at UBS, the fastest pace by a consumer app in history to reach that mark.

n’s close associates praise his ability to balance OpenAI’s priorities. No one better navigates between the “Scylla of misplaced idealism” and the “Charybdis of myopic ambition,” Mr. Thiel said. 

Mr. Altman said he delayed the release of the latest version of its model, GPT-4, from last year to March to run additional safety tests. Users had reported some disturbing experiences with the model, integrated into Bing, where the software hallucinated—meaning it made up answers to questions it didn’t know. It issued ominous warnings and made threats. 

“The way to get it right is to have people engage with it, explore these systems, study them, to learn how to make them safe,” Mr. Altman said.

After Microsoft’s initial investment is paid back, it would capture 49% of OpenAI’s profits until the profit cap, up from 21% under prior arrangements, the documents show. OpenAI Inc., the nonprofit parent, would get the rest.

He has put almost all his liquid wealth in recent years in two companies. He has put $375 million into Helion Energy, which is seeking to create carbon-free energy from nuclear fusion and is close to creating “legitimate net-gain energy in a real demo,” Mr. Altman said.

He has also put $180 million into Retro, which aims to add 10 years to the human lifespan through “cellular reprogramming, plasma-inspired therapeutics and autophagy,” or the reuse of old and damaged cell parts, according to the company. 

He noted how much easier these problems are, morally, than AI. “If you’re making nuclear fusion, it’s all upside. It’s just good,” he said. “If you’re making AI, it is potentially very good, potentially very terrible.” 

It certainly informed his libertarianism, which inclined in the direction of an Ayn Rand-inspired valorization of entrepreneurial superman-geniuses whose great acts of capitalistic creativity benefit all of mankind. Thiel also tended to follow Rand in viewing the masses as moochers who empower Big Government to crush these superman-geniuses.

Thiel became something of an opportunistic populist inclined to view liberal elites and institutions as posing the greatest obstacle to building an economy and culture of dynamistic creativity—and eager to mobilize the anger and resentment of “the people” as a wrecking ball to knock them down. 

the failure of the Trump administration to break more decisively from the political status quo left Thiel uninterested in playing a big role in the 2020 election cycle.

Does Thiel personally believe that the 2020 election was stolen from Trump? I doubt it. It’s far more likely he supports the disruptive potential of encouraging election-denying candidates to run and helping them to win.

Thiel is moved to indignation by the fact that since 1958 no commercial aircraft (besides the long-decommissioned Concorde) has been developed that can fly faster than 977 kilometers per hou

Thiel is, first and foremost, a dynamist—someone who cares above all about fostering innovation, exploration, growth, and discovery.

the present looks and feels pretty much the same as 1969, only “with faster computers and uglier cars.” 

Thiel’s approach to the problem is distinctive in that he sees the shortfall as evidence of a deeper and more profound moral, aesthetic, and even theological failure. Human beings are capable of great creativity and invention, and we once aspired to achieve it in every realm. But now that aspiration has been smothered by layer upon layer of regulation and risk-aversion. “Legal sclerosis,” Thiel claimed in that same book review, “is likely a bigger obstacle to the adoption of flying cars than any engineering problem.”

Progress in science and technology isn’t innate to human beings, Thiel believes. It’s an expression of a specific cultural or civilizational impulse that has its roots in Christianity and reached a high point during the Victorian era of Western imperialism

Thiel aims to undermine the progressive liberalism that dominates the mainstream media, the federal bureaucracy, the Justice Department, and the commanding heights of culture (in universities, think tanks, and other nonprofits).

In Thiel’s view, recapturing civilizational greatness through scientific and technological achievement requires fostering a revival of a kind of Christian Prometheanism (a monotheistic variation on the rebellious creativity and innovation pursued by the demigod Prometheus in ancient Greek mythology)

Against those who portray modern scientific and technological progress as a rebellion against medieval Christianity, Thiel insists it is Christianity that encourages a metaphysical optimism about transforming and perfecting the world, with the ultimate goal of turning it into “a place where no accidents can happen” and the achievement of “personal immortality” becomes possible

All that’s required to reach this transhuman end is that we “remain open to an eschatological frame in which God works through us in building the kingdom of heaven today, here on Earth—in which the kingdom of heaven is both a future reality and something partially achievable in the present.” 

As Thiel put it last summer in a wide-ranging interview with the British website UnHerd, the Christian world “felt very expansive, both in terms of the literal empire and also in terms of the progress of knowledge, of science, of technology, and somehow that was naturally consonant with a certain Christian eschatology—a Christian vision of history.”

JD Vance is quoted on the subject of what this political disruption might look like during a Trump presidential restoration in 2025. Vance suggests that Trump should “fire every single midlevel bureaucrat, every civil servant in the administrative state, replace them with our people. And when the courts stop [him], stand before the country, and say, ‘the chief justice has made his ruling. Now let him enforce it.’”

Another Thiel friend and confidante discussed at length in Vanity Fair, neo-reactionary Curtis Yarvin, takes the idea of disrupting the liberal order even further, suggesting various ways a future right-wing president (Trump or someone else) could shake things up, shredding the smothering blanket of liberal moralism, conformity, rules, and regulations, thereby encouraging the creation of something approaching a scientific-technological wild west, where innovation and experimentation rule the day. Yarvin’s preferred path to tearing down what he calls the liberal “Cathedral,” laid out in detail on a two-hour Claremont Institute podcast from May 2021, involves a Trump-like figure seizing dictatorial power in part by using a specially designed phone app to direct throngs of staunch supporters (Jan. 6-style) to overpower law enforcement at key locations around the nation’s capital.  

this isn’t just an example of guilt-by-association. These are members of Thiel’s inner circle, speaking publicly about ways of achieving shared goals. Thiel funded Vance’s Senate campaign to the tune of at least $15 million. Is it likely the candidate veered into right-wing radicalism with a Vanity Fair reporter in defiance of his campaign’s most crucial donor?

As for Yarvin, Thiel continued to back his tech start up (Urbit) after it became widely known he was the pseudonymous author behind the far-right blog “Unqualified Reservations,” and as others have shown, the political thinking of the two men has long overlapped in numerous other ways. 

He’s deploying his considerable resources to empower as many people and groups as he can, first, to win elections by leveraging popular disgust at corrupt institutions—and second, to use the power they acquire to dismantle or even topple those institutions, hopefully allowing a revived culture of Christian scientific-technological dynamism to arise from out of the ruins.  

Far more than most big political donors, Thiel appears to care only about the extra-political goal of his spending. How we get to a world of greater dynamism—whether it will merely require selective acts of troublemaking disruption, or whether, instead, it will ultimately involve smashing the political order of the United States to bits—doesn’t really concern him. Democratic politics itself—the effort of people with competing interests and clashing outlooks to share rule for the sake of stability and common flourishing—almost seems like an irritant and an afterthought to Peter Thiel.

What we do have is the opportunity to enlighten ourselves about what these would-be Masters of the Universe hope to accomplish—and to organize politically to prevent them from making a complete mess of things in the process.

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.”

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.”

ver since, Luddite has been a derogatory word—shorthand for one who blindly hates or doesn’t understand technology.

Now, with nearly half of Americans worried about how AI will affect jobs, Luddism has blossomed. The new Luddites—a growing contingent of workers, critics, academics, organizers, and writers—say that too much power has been concentrated in the hands of the tech titans, that tech is too often used to help corporations slash pay and squeeze workers, and that certain technologies must not merely be criticized but resisted outright.

what I’ve seen over the past 10 years—the rise of gig-app companies that have left workers precarious and even impoverished; the punishing, gamified productivity regimes put in place by giants such as Amazon; the conquering of public life by private tech platforms and the explosion of screen addiction; and the new epidemic of AI plagiarism—has left me sympathizing with tech’s discontents.

I consider myself a Luddite not because I want to halt progress or reject technology itself. But I believe, as the original Luddites argued in a particularly influential letter threatening the industrialists, that we must consider whether a technology is “hurtful to commonality”—whether it causes many to suffer for the benefit of a few—and oppose it when necessary.

“It’s not a primitivism: We don’t reject all technology, but we reject the technology that is foisted on us,” Jathan Sadowski, a social scientist at Monash University, in Australia, told me. He’s a co-host, with the journalist Ed Ongweso Jr., of This Machine Kills, an explicitly pro-Luddite podcast.

The science-fiction author Cory Doctorow has declared all of sci-fi a Luddite literature, writing that “Luddism and science fiction concern themselves with the same questions: not merely what the technology does, but who it does it for and who it does it to.

The New York Times has profiled a hip cadre of self-proclaimed “‘Luddite’ teens.” As the headline explained, they “don’t want your likes.”

By drawing a red line against letting studios control AI, the WGA essentially waged the first proxy battle between human workers and AI. It drew attention to the fight, resonated with the public, and, after a 148-day strike, helped the guild attain a contract that banned studios from dictating the use of AI.

Special effects software can give your music all sorts of subtle vibes. For $299, for instance, you can make your song sound as though it was recorded in Sound City Studios in Los Angeles, on the $20,000 vintage microphones with the $100,000 mixing console that recorded Fleetwood Mac and Nirvana. For $259 you can simulate the Beatles’ Abbey Road Studios

In the past, when you assembled all the tracks for a song, it would have to be mixed and mastered in a studio by a sound engineer adjusting the levels. Now an app will do it for you.

Now, all you need to do is get the files uploaded to streaming services. If you are signed with a label, they will do that for you, but you don’t need a record deal to do that. There are companies such as DistroKid that act as postmen: for £17.99 a year, you can ensure that the song you created in your bedroom is available on multiple streaming platforms.

Some artists thrive on social media. It suits lively, quirky performers like Ryder, and artists who want to experiment with different genres. Mxmtoon, a 23-year-old American YouTuber, singer-songwriter and ukulele player, is also a streamer on Twitch, a platform on which people watch others playing online games, has published graphic novels and made a podcast. Maia — the artist’s name — describes mxmtoon as “a multi-hyphenated project”.

More traditional musicians struggle with some aspects of tech. “We get together,” says Sital-Singh of his contemporaries in the business, “and have a little moan about how everyone’s telling us to do TikTok and we can’t bring ourselves to dance and we feel old and decrepit.”

Even digital natives struggle sometimes: “I already have nostalgia for a simpler past, even though I’m 23,” says Maia. “It’s exciting but it does put so much pressure on a normal individual to be an entrepreneur to advertise their own personal brand.”

Journalists, regrettably, no longer have the power they once did. What matters these days is social media. The A&R (artists and repertoire) people at record companies who would once have hung out in basement clubs scouting for new talent now sit in meetings examining the data on artists’ social media performance.

Now that the whole world’s music is available all over the world at the click of a play button, there’s a greater diversity among top-selling artists.

People making videos of themselves performing or dancing to the song on TikTok helped propel it to the stratosphere. It has been streamed a billion times. Sethi now plays to packed venues in America and Europe; last year, he performed at Coachella, America’s Glastonbury. “Without digital technology I would be a south Asian indy musician, working on the fringes of Bollywood,” he says from his home in New York.

For musicians, it’s more ambiguous. Because the costs of making music are lower, anybody with ambition can have a go. Many more people, as a result, are getting into the music business. According to PPL, the organisation which distributes money to music performers and rights-holders, the number of registered artists has risen from 61,310, when the industry was at its nadir, to 165,039 last year.

That makes the business fiercely competitive. As Will Page, former chief economist at Spotify and author of Tarzan Economics, points out, around 100,000 tracks are being uploaded on to Spotify every day: that’s more than were released in an entire calendar year in the 1980s

That has cemented the power of the record companies. When the digital revolution started, it was widely expected that record labels would cease to exist, and be replaced by a model in which everybody promoted and distributed their own music. That’s not what has happened: because it’s so difficult to get noticed, embryonic stars need record labels to promote them.

A label invests in the production of the music, the styling of the band, video content, interviews, touring and the crucial business of getting a song on a streaming service’s playlist that suggests the song to listeners to suit their tastes. Artists that are signed with major labels get paid more, per stream, than those that aren’t.

Three quarters of streamed tracks have one of the major record labels behind them. And even though streaming is booming, it doesn’t contribute much to the incomes of the vast majority of artists.

Most artists stay hungry. A single stream will earn a musician anywhere between 0.1p and 2.4p. Crispin Hunt reckons that on average a million streams for a song — a wild ambition for most musicians — will, if you have to pay a cut to a record company, probably make you £1,000

If you’ve then got to pay your manager 20 per cent, and divide the rest between the four band members, “it barely pays for a Sainsbury’s shop. That’s why music is dominated by middle-class people called Crispin whose parents can afford to buy them an electric guitar and a laptop.”

For Christie Gardner, half of Lilo, a two-woman band, it helps planning gigs. “You can see where your listeners are and you can tell what they’re listening to. We make decisions about shows on that basis.” But for most bands, the economics of live performance are pretty grim.

Deathcrash’s manager Joe Taylor says that the band has been offered the opportunity of a European tour supporting a much bigger act. It would be good for their career but not their bank balance. The fees per show would be €200; once the costs of a sound engineer, a tour van, a driver, fuel, hotels and a carnet for importing musical instruments into the EU had been factored in, they would lose £15,000.

music has always been an uneconomic business, which people subsidise through other activities. The fiddler in the village pub probably worked in the fields in the daytime and played for money and fun in the evenings and at the weekend, rather as Ryder ran a juice bar and sang at weddings. These days, there is also the wafer-thin chance that they might end up being one of the 1,200 artists who make more than $1 million a year on Spotify

There are some signs that in the new musical economy, the balance of power between artists and the big record companies may have tipped slightly in the artists’ favour

the share of streaming revenues going to artists increased from 19.7 per cent to 23.3 per cent between 2012 and 2021 and that going to songwriters has risen from 8 per cent in 2008 to 15 per cent in 2021. “Outcomes for consumers, artists and songwriters,” it concludes, “are getting better.”

Most of the extra revenues generated by streaming are going to the top earners. But the stars are not the only ones benefiting. Between 2017 and 2022, the number of artists earning over $1 million on Spotify more than doubled, but so did the number earning over $10,000

more than two fifths of artists who release their own music aren’t expecting to make a full-time career. They’re in it for fun, for the love of it, or to be able to show their mum that they have released a song on Spotify.

It seems likely that the more music is being created, the greater the chance that wonderful tunes are being written, but it’s not necessarily the case. The best stuff might get buried under a mound of mediocrity.

Russian military doctrine states that Russia would use nuclear weapons in the event of attacks against key Russian assets or threats to the existence of the state, and experts believe Russia could use nuclear weapons first in a crisis to signal resolve.

Russia has seen how important space-based assets can be on the battlefield in Ukraine. Starlink, with its thousands of satellites orbiting Earth, provides Ukrainian forces with uninterrupted communication. The U.S. Department of Defense openly discusses its investments in large satellite constellations. Hundreds of satellites used for missile warning, intelligence and communications are seen as a way to be more resilient against a variety of growing space threats. Moscow would look for ways to target these large satellite constellations and to erode the advantage they provide.

Nor is it new for Russia to violate nuclear arms control agreements. In recent years, Russia has violated the 1987 Intermediate-Range Nuclear Forces Treaty, suspended its participation in the 2010 New Strategic Arms Reduction Treaty, and de-ratified the Comprehensive Test Ban Treaty. Backing out of arms control commitments is part of Russia’s modus operandi.

But a nuclear detonation in space is indiscriminate. It would degrade or destroy any satellites in its path and within the same orbital region. It wouldn’t just affect U.S. satellites but also the aggressor’s own satellites, as well as an unknown number of satellites owned by the over 90 countries operating in space, and astronauts living on the International Space Station and Chinese space station

Russia, however, has less to lose: Its once vaunted space program is in decline, dinged by sanctions, and said it intends to withdraw from the International Space Station program after 2024. Moscow is now well behind China in its total number of operating on-orbit satellites.

Third, we need to be realistic about prospects for future arms control with Russia. Moscow has shown a disregard for its treaty commitments. Just last month, Moscow rejected attempts by the Biden administration to restart bilateral arms control talks. Rather than trying again, the administration should instead focus on strengthening deterrence by improving our own capabilities and building multilateral coalitions for responsible nuclear behavior

Finally, policymakers need to protect our intelligence sources and intelligence gathering methods

With Russian officials already demanding proof of what the United States knows, declassifying those sources and methods plays directly into Moscow’s hands and jeopardizes those channels for future intelligence collection.

he trickiest question may be how to prevent abuse. AI generators have technological boundaries, but not morals, and it’s relatively easy for users to trick them into creating content that depicts violence, rape, sex with children or a celebrity — or even a crush from work who never consented to appear

In some cases, the engines themselves are trained on porn images whose subjects didn’t explicitly agree to the new use. Currently, no federal laws protect the victims of nonconsensual deepfakes.

Adult entertainment is a giant industry accounting for a substantial chunk of all internet traffic: Major porn sites get more monthly visitors and page views than Amazon, Netflix, TikTok or Zoom

The industry is a habitual early adopter of new technology, from VHS to DVD to dot com. In the mid-2000s, porn companies set up massive sites where users upload and watch free videos, and ad sales foot the bills.

At last year’s AVN conference, Steven Jones said his peers looked at him “like he was crazy” when he talked about AI opportunities: “Nobody was interested.” This year, Jones said, he’s been “the belle of the ball.”

He called up his old business partner, and the two immediately spent about $550,000 securing the web domains for porn dot ai, deepfake dot com and deepfakes dot com, Jones said. “Lightspeed” was back.

One major model, Stable Diffusion, shares its code publicly, and some technologists have figured out how to edit the code to allow for sexual images

What keeps Jones up at night is people trying to use his company’s tools to generate images of abuse, he said. The models have some technological guardrails that make it difficult for users to render children, celebrities or acts of violence. But people are constantly looking for workarounds.

So with help from an angel investor he will not name, Jones hired five employees and a handful of offshore contractors and started building an image engine trained on bundles of freely available pornographic images, as well as thousands of nude photos from Jones’s own collection

Users create what Jones calls a “dream girl,” prompting the AI with descriptions of the character’s appearance, pose and setting. The nudes don’t portray real people, he said. Rather, the goal is to re-create a fantasy from the user’s imagination.

The AI-generated images got better, their computerized sheen growing steadily less noticeable. Jones grew his user base to 500,000 people, many of whom pay to generate more images than the five per day allotted to free accounts, he said. The site’s “power users” generate AI porn for 10 hours a day, he said.

Jones described the site as an “artists’ community” where people can explore their sexualities and fantasies in a safe space. Unlike some corners of the traditional adult industry, no performers are being pressured, underpaid or placed in harm’s way

And critically, consumers don’t have to wait for their favorite OnlyFans performer to come online or trawl through Pornhub to find the content they like.

Next comes AI-generated video — “porn’s holy grail,” Jones said. Eventually, he sees the technology becoming interactive, with users giving instructions to lifelike automated “performers.” Within two years, he said, there will be “fully AI cam girls,” a reference to creators who make solo sex content.

It costs $12 per day to rent a server from Amazon Web Services, he said, and generating a single picture requires users to have access to a corresponding server. His users have so far generated more than 1.6 million images.

Copyright holders including newspapers, photographers and artists have filed a slew of lawsuits against AI companies, claiming the companies trained their models on copyrighted content. If plaintiffs win, it could cut off the free-for-all that benefits entrepreneurs such as Jones.

But Jones’s plan to create consumer-friendly AI porn engines faced significant obstacles. The companies behind major image-generation models used technical boundaries to block “not safe for work” content and, without racy images to learn from, the models weren’t good at re-creating nude bodies or scenes.

Jones said his team takes down images that other users flag as abusive. Their list of blocked prompts currently contains 1,000 terms including “high school.”

“I see certain things people type in, and I just hope to God they’re trying to test the model, like we are. I hope they don’t actually want to see the things they’re typing in.

Peter Acworth, the owner of kink dot com, is trying to teach an AI porn generator to understand even subtler concepts, such as the difference between torture and consensual sexual bondage. For decades Acworth has pushed for spaces — in the real world and online — for consenting adults to explore nonconventional sexual interests. In 2006, he bought the San Francisco Armory, a castle-like building in the city’s Mission neighborhood, and turned it into a studio where his company filmed fetish porn until shuttering in 2017.

Now, Acworth is working with engineers to train an image-generation model on pictures of BDSM, an acronym for bondage and discipline, dominance and submission, sadism and masochism.

Others alluded to a porn apocalypse, with AI wiping out existing models of adult entertainment.“Look around,” said Christian Burke, head of engineering at the adult-industry payment app Melon, gesturing at performers huddled, laughing and hugging across the show floor. “This could look entirely different in a few years.”

But the age of AI brings few guarantees for the people, largely women, who appear in porn. Many have signed broad contracts granting companies the rights to reproduce their likeness in any medium for the rest of time

Not only could performers lose income, Walters said, they could find themselves in offensive or abusive scenes they never consented to.

Lana Smalls, a 23-year-old performer whose videos have been viewed 20 million times on Pornhub, said she’s had colleagues show up to shoots with major studios only to be surprised by sweeping AI clauses in their contracts.

“This industry is too fragmented for collective bargaining,” Spiegler said. “Plus, this industry doesn’t like rules.”
