The key issue is not “human-competitive” intelligence (as the open letter puts it); it’s what happens after AI gets to smarter-than-human intelligence. Key thresholds there may not be obvious, we definitely can’t calculate in advance what happens when, and it currently seems imaginable that a research lab would cross critical lines without noticing.

Many researchers steeped in these issues, including myself, expect that the most likely result of building a superhumanly smart AI, under anything remotely like the current circumstances, is that literally everyone on Earth will die. Not as in “maybe possibly some remote chance,” but as in “that is the obvious thing that would happen.”

It’s not that you can’t, in principle, survive creating something much smarter than you; it’s that it would require precision and preparation and new scientific insights, and probably not having AI systems composed of giant inscrutable arrays of fractional numbers.

Absent that caring, we get “the AI does not love you, nor does it hate you, and you are made of atoms it can use for something else.”

Without that precision and preparation, the most likely outcome is AI that does not do what we want, and does not care for us nor for sentient life in general. That kind of caring is something that could in principle be imbued into an AI but we are not ready and do not currently know how.

The likely result of humanity facing down an opposed superhuman intelligence is a total loss

To visualize a hostile superhuman AI, don’t imagine a lifeless book-smart thinker dwelling inside the internet and sending ill-intentioned emails. Visualize an entire alien civilization, thinking at millions of times human speeds, initially confined to computers—in a world of creatures that are, from its perspective, very stupid and very slow. A sufficiently intelligent AI won’t stay confined to computers for long. In today’s world you can email DNA strings to laboratories that will produce proteins on demand, allowing an AI initially confined to the internet to build artificial life forms or bootstrap straight to postbiological molecular manufacturing.

There’s no proposed plan for how we could do any such thing and survive. OpenAI’s openly declared intention is to make some future AI do our AI alignment homework. Just hearing that this is the plan ought to be enough to get any sensible person to panic. The other leading AI lab, DeepMind, has no plan at all.

An aside: None of this danger depends on whether or not AIs are or can be conscious; it’s intrinsic to the notion of powerful cognitive systems that optimize hard and calculate outputs that meet sufficiently complicated outcome criteria.

I didn’t also mention that we have no idea how to determine whether AI systems are aware of themselves—since we have no idea how to decode anything that goes on in the giant inscrutable arrays—and therefore we may at some point inadvertently create digital minds which are truly conscious and ought to have rights and shouldn’t be owned.

I refrained from signing because I think the letter is understating the seriousness of the situation and asking for too little to solve it.

the thing about trying this with superhuman intelligence is that if you get that wrong on the first try, you do not get to learn from your mistakes, because you are dead. Humanity does not learn from the mistake and dust itself off and try again, as in other challenges we’ve overcome in our history, because we are all gone.

If we held anything in the nascent field of Artificial General Intelligence to the lesser standards of engineering rigor that apply to a bridge meant to carry a couple of thousand cars, the entire field would be shut down tomorrow.

We are not on course to be prepared in any reasonable time window. There is no plan. Progress in AI capabilities is running vastly, vastly ahead of progress in AI alignment or even progress in understanding what the hell is going on inside those systems

Many researchers working on these systems think that we’re plunging toward a catastrophe, with more of them daring to say it in private than in public; but they think that they can’t unilaterally stop the forward plunge, that others will go on even if they personally quit their jobs.

This is a stupid state of affairs, and an undignified way for Earth to die, and the rest of humanity ought to step in at this point and help the industry solve its collective action problem.

When the insider conversation is about the grief of seeing your daughter lose her first tooth, and thinking she’s not going to get a chance to grow up, I believe we are past the point of playing political chess about a six-month moratorium.

The moratorium on new large training runs needs to be indefinite and worldwide. There can be no exceptions, including for governments or militaries. If the policy starts with the U.S., then China needs to see that the U.S. is not seeking an advantage but rather trying to prevent a horrifically dangerous technology which can have no true owner and which will kill everyone in the U.S. and in China and on Earth

Here’s what would actually need to be done:

Shut down all the large GPU clusters (the large computer farms where the most powerful AIs are refined). Shut down all the large training runs

Put a ceiling on how much computing power anyone is allowed to use in training an AI system, and move it downward over the coming years to compensate for more efficient training algorithm

Track all GPUs sold. If intelligence says that a country outside the agreement is building a GPU cluster, be less scared of a shooting conflict between nations than of the moratorium being violated; be willing to destroy a rogue datacenter by airstrike.

Frame nothing as a conflict between national interests, have it clear that anyone talking of arms races is a fool

Make it explicit in international diplomacy that preventing AI extinction scenarios is considered a priority above preventing a full nuclear exchange, and that allied nuclear countries are willing to run some risk of nuclear exchange if that’s what it takes to reduce the risk of large AI training runs.

when your policy ask is that large, the only way it goes through is if policymakers realize that if they conduct business as usual, and do what’s politically easy, that means their own kids are going to die too.

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.” 

And yet, when people act as if Mr. Altman has nearly realized his long-held vision, he pushes back.

This past week, more than a thousand A.I. experts and tech leaders called on OpenAI and other companies to pause their work on systems like ChatGPT, saying they present “profound risks to society and humanity.”

As people realize that this technology is also a way of spreading falsehoods or even persuading people to do things they should not do, some critics are accusing Mr. Altman of reckless behavior.

“The hype over these systems — even if everything we hope for is right long term — is totally out of control for the short term,” he told me on a recent afternoon. There is time, he said, to better understand how these systems will ultimately change the world.

Many industry leaders, A.I. researchers and pundits see ChatGPT as a fundamental technological shift, as significant as the creation of the web browser or the iPhone. But few can agree on the future of this technology.

Some believe it will deliver a utopia where everyone has all the time and money ever needed. Others believe it could destroy humanity. Still others spend much of their time arguing that the technology is never as powerful as everyone says it is, insisting that neither nirvana nor doomsday is as close as it might seem.

he is often criticized from all directions. But those closest to him believe this is as it should be. “If you’re equally upsetting both extreme sides, then you’re doing something right,” said OpenAI’s president, Greg Brockman.

To spend time with Mr. Altman is to understand that Silicon Valley will push this technology forward even though it is not quite sure what the implications will be

in 2019, he paraphrased Robert Oppenheimer, the leader of the Manhattan Project, who believed the atomic bomb was an inevitability of scientific progress. “Technology happens because it is possible,” he said

His life has been a fairly steady climb toward greater prosperity and wealth, driven by an effective set of personal skills — not to mention some luck. It makes sense that he believes that the good thing will happen rather than the bad.

He said his company was building technology that would “solve some of our most pressing problems, really increase the standard of life and also figure out much better uses for human will and creativity.”

He was not exactly sure what problems it will solve, but he argued that ChatGPT showed the first signs of what is possible. Then, with his next breath, he worried that the same technology could cause serious harm if it wound up in the hands of some authoritarian government.

Kelly Sims, a partner with the venture capital firm Thrive Capital who worked with Mr. Altman as a board adviser to OpenAI, said it was like he was constantly arguing with himself.

“In a single conversation,” she said, “he is both sides of the debate club.”

He takes pride in recognizing when a technology is about to reach exponential growth — and then riding that curve into the future.

he is also the product of a strange, sprawling online community that began to worry, around the same time Mr. Altman came to the Valley, that artificial intelligence would one day destroy the world. Called rationalists or effective altruists, members of this movement were instrumental in the creation of OpenAI.

Does it make sense to ride that curve if it could end in diaster? Mr. Altman is certainly determined to see how it all plays out.

“Why is he working on something that won’t make him richer? One answer is that lots of people do that once they have enough money, which Sam probably does. The other is that he likes power.”

“He has a natural ability to talk people into things,” Mr. Graham said. “If it isn’t inborn, it was at least fully developed before he was 20. I first met Sam when he was 19, and I remember thinking at the time: ‘So this is what Bill Gates must have been like.

poker taught Mr. Altman how to read people and evaluate risk.

It showed him “how to notice patterns in people over time, how to make decisions with very imperfect information, how to decide when it was worth pain, in a sense, to get more information,” he told me while strolling across his ranch in Napa. “It’s a great game.”

He believed, according to his younger brother Max, that he was one of the few people who could meaningfully change the world through A.I. research, as opposed to the many people who could do so through politics.

In 2019, just as OpenAI’s research was taking off, Mr. Altman grabbed the reins, stepping down as president of Y Combinator to concentrate on a company with fewer than 100 employees that was unsure how it would pay its bills.

Within a year, he had transformed OpenAI into a nonprofit with a for-profit arm. That way he could pursue the money it would need to build a machine that could do anything the human brain could do.

Mr. Brockman, OpenAI’s president, said Mr. Altman’s talent lies in understanding what people want. “He really tries to find the thing that matters most to a person — and then figure out how to give it to them,” Mr. Brockman told me. “That is the algorithm he uses over and over.”

Mr. Yudkowsky and his writings played key roles in the creation of both OpenAI and DeepMind, another lab intent on building artificial general intelligence.

“These are people who have left an indelible mark on the fabric of the tech industry and maybe the fabric of the world,” he said. “I think Sam is going to be one of those people.”

The trouble is, unlike the days when Apple, Microsoft and Meta were getting started, people are well aware of how technology can transform the world — and how dangerous it can be.

Mr. Scott of Microsoft believes that Mr. Altman will ultimately be discussed in the same breath as Steve Jobs, Bill Gates and Mark Zuckerberg.

The woman was the Canadian singer Grimes, Mr. Musk’s former partner, and the hat guy was Eliezer Yudkowsky, a self-described A.I. researcher who believes, perhaps more than anyone, that artificial intelligence could one day destroy humanity.

The selfie — snapped by Mr. Altman at a party his company was hosting — shows how close he is to this way of thinking. But he has his own views on the dangers of artificial intelligence.

In March, Mr. Altman tweeted out a selfie, bathed by a pale orange flash, that showed him smiling between a blond woman giving a peace sign and a bearded guy wearing a fedora.

He also helped spawn the vast online community of rationalists and effective altruists who are convinced that A.I. is an existential risk. This surprisingly influential group is represented by researchers inside many of the top A.I. labs, including OpenAI.

They don’t see this as hypocrisy: Many of them believe that because they understand the dangers clearer than anyone else, they are in the best position to build this technology.

Mr. Altman believes that effective altruists have played an important role in the rise of artificial intelligence, alerting the industry to the dangers. He also believes they exaggerate these dangers.

As OpenAI developed ChatGPT, many others, including Google and Meta, were building similar technology. But it was Mr. Altman and OpenAI that chose to share the technology with the world.

Many in the field have criticized the decision, arguing that this set off a race to release technology that gets things wrong, makes things up and could soon be used to rapidly spread disinformation.

Mr. Altman argues that rather than developing and testing the technology entirely behind closed doors before releasing it in full, it is safer to gradually share it so everyone can better understand risks and how to handle them.

He told me that it would be a “very slow takeoff.”

When I asked Mr. Altman if a machine that could do anything the human brain could do would eventually drive the price of human labor to zero, he demurred. He said he could not imagine a world where human intelligence was useless.

If he’s wrong, he thinks he can make it up to humanity.

His grand idea is that OpenAI will capture much of the world’s wealth through the creation of A.G.I. and then redistribute this wealth to the people. In Napa, as we sat chatting beside the lake at the heart of his ranch, he tossed out several figures — $100 billion, $1 trillion, $100 trillion.

If A.G.I. does create all that wealth, he is not sure how the company will redistribute it. Money could mean something very different in this new world.

But as he once told me: “I feel like the A.G.I. can help with that.”

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.

Karahan Tepe, and its penis chamber, and everything that inexplicably surrounds the chamber – shrines, cells, altars, megaliths, audience halls et al – is vastly older than anything comparable, and plumbs quite unimaginable depths of time, back before agriculture, probably back before normal pottery, right back to a time when we once thought human ‘civilisation’ was simply impossible.

After all, hunter gatherers – cavemen with flint arrowheads – without regular supplies of grain, without the regular meat and milk of domesticated animals, do not build temple-towns with water systems.

Taken together with its age, complexity, sophistication, and its deep, resonant mysteriousness, and its many sister sites now being unearthed across the Harran Plains – collectively known as the Tas Tepeler, or the ‘stone hills’ – these carved, ochre-red rocks, so silent, brooding, and watchful in the hard whirring breezes of the semi-desert, constitute what might just be the greatest archaeological revelation in the history of humankind.

The solitary Kurdish man, on that summer’s day in 1994, had made an irreversibly profound discovery – which would eventually lead to the penis pillars of Karahan Tepe, and an archaeological anomaly which challenges, time and again, everything we know of human prehistory.

in late 1994 the German archaeologist Klaus Schmidt came to the site of Gobekli Tepe to begin his slow, diligent excavations of its multiple, peculiar, enormous T-stones, which are generally arranged in circles – like the standing stones of Avebury or Stonehenge. Unlike European standing stones, however, the older Turkish megaliths are often intricately carved: with images of local fauna. Sometimes the stones depict cranes, boars, or wildfowl: creatures of the hunt. There are also plenty of leopards, foxes, and vultures. Occasionally these animals are depicted next to human heads.

The obsession with the penis is obvious – more so, now we have the benefit of hindsight provided by Karahan Tepe and the other sites. Very few representations of women have emerged from the Tas Tepeler so far; there is one obscene caricature of a woman perhaps giving birth. Whatever inspired these temple-towns it was a not a benign matriarchal culture. Quite the opposite, maybe.

Urfa man now has a silent hall of his own in one of Turkey’s greatest archaeological galleries. More importantly, we can now see that Urfa man has the same body stance of the T-shaped man-pillars at Gobekli (and in many of the Tas Tepeler): his arms are in front of him, protecting his penis

‘Gobekli Tepe upends our view of human history. We always thought that agriculture came first, then civilisation: farming, pottery, social hierarchies. But here it is reversed, it seems the ritual centre came first, then when enough hunter gathering people collected to worship – or so I believe – they realised they had to feed people. Which means farming.’ He waved at the surrounding hills, ‘It is no coincidence that in these same hills in the Fertile Crescent men and women first domesticated the local wild einkorn grass, becoming wheat, and they also first domesticated pigs, cows and sheep. This is the place where Homo sapiens went from plucking the fruit from the tree, to toiling and sowing the ground.’

People were already speculating that – if you see the Garden of Eden mythos as an allegory of the Neolithic Revolution: i.e. our fall from the relative ease of hunter-gathering to the relative hardships of farming (and life did get harder when we first started farming, as we worked longer hours, and caught diseases from domesticated animals), then Gobekli Tepe and its environs is probably the place where this happened

‘I believe Gobekli Tepe is a temple in Eden’. It’s a quote I reused, to some controversy, because people took Klaus literally. But he did not mean it literally. He meant it allegorically.

This number is so large it is hard to take in. For comparison the Great Pyramid at Giza is 4,500 years old. Stonehenge is 5,000 years old. The Cairn de Barnenez tomb-complex in Brittany, perhaps the oldest standing structure in Europe, could be up to 7,000 years old.

I do definitely know this: some time in 8000 BC the creators of Gobekli Tepe buried their great structures under tons of rubble. They entombed it. We can speculate why. Did they feel guilt? Did they need to propitiate an angry God? Or just want to hide it?’ Klaus was also fairly sure on one other thing. ‘Gobekli Tepe is unique.’

These days Gobekli Tepe is not just a famous archaeological site, it is a Unesco World-Heritage-listed tourist honeypot which can generate a million visitors a year. It is all enclosed by a futuristic hi-tech steel-and-plastic marquee (no casual wandering around taking photos of the stones and workers

Necmi shows me the gleaming museum built to house the greatest finds from the region: including a 11,000 year old statue, retrieved from beneath the centre of Sanliurfa itself, and perhaps the world’s oldest life size carved human figure

‘We have found no homes, no human remains. Where is everyone, did they gather for festivals, then disperse? As for their religion, I have no real idea, perhaps Gobekli Tepe was a place of excarnation, for exposing the bones of the dead to be consumed by vultures, so the bodies have all gone

Aslan tells me how archaeologists at Gobekli have also, more recently, found tantalising evidence of alcohol: huge troughs with the chemical residue of fermentation, indicating mighty ritual feasts, maybe.

he explains how scientists at Karahan Tepe, as well as Gobekli Tepe, have now found evidence of homes.

The builders lived here. They ate their roasted game here. They slept here. And they used, it seems, a primitive but poetic form of pottery, shaped from polished stone. They possibly did elaborate manhood rituals in the Karahan Tepe penis chambe

Yet still we have no sign at all of contemporary agriculture; they were, it still appears, hunter gatherers, but of unnerving sophistication.

Another unnerving oddity is the curious number of carvings which show people with six fingers. Is this symbolic, or an actual deformity? Perhaps the mark of a strange tribe?

Karahan Tepe is stupefyingly big. ‘So far,’ he says, ‘We have dug up maybe 1 per cent of the site’ – and it is already impressive. I ask him how many pillars – T stones – might be buried here. He casually points at a rectangular rock peering above the dry grass. ‘That’s probably another megalith right there, waiting to be excavated. I reckon there are probably thousands more of them, all around us. We are only at the beginning. And there could be dozens more Tas Tepeler we have not yet found, spread over hundreds of kilometres.’

Karahan too was definitely and purposely buried. That is the reason Necmi and his team were able to unearth the penis pillars so quickly, all they had to do was scoop away the backfill, exposing the phallic pillars, sculpted from living rock.

the most remarkable answer of all, and it is this: archaeologists in southeastern Turkey are, at this moment, digging up a wild, grand, artistically coherent, implausibly strange, hitherto-unknown-to-us religious civilisation, which has been buried in Mesopotamia for ten thousand years. And it was all buried deliberately.

Since 2016, there have been two competing visions for the Democratic Party. One is the promise that began with Barack Obama of a multiracial coalition that would grow stronger as America’s demographics shifted; the other is the political revolution championed by Bernie Sanders as a way to unite nonvoters with the working class

Ms. Ocasio-Cortez bridges the gap between the two

what’s clear is that at a time when Democrats are struggling, she is quietly laying the groundwork to build a coalition broader than the one she came to power with, unafraid to take risks along the way.

After five years in Congress, she has emerged as a tested navigator of its byzantine systems, wielding her celebrity to further her political aims in a way few others have.

Three terms in, one gets the sense that we’re witnessing a skilled tactician exiting her political adolescence and coming into her own as a veteran operator out to reform America’s most dysfunctional political body.

To grasp what sets Ms. Ocasio-Cortez apart from many of her colleagues, you have to understand where she finds allies

In 2019, she and Senator Ted Cruz of Texas considered joining forces to write a bill that would bar former members of Congress from becoming lobbyists. Asked why she would consider an alliance with someone so loathed by liberals, she said, “I will swallow all of my distaste in this situation because we have found a common interest.”

It was a window into the politician she would become: pragmatic and results-driven, willing to work with people she considers her political adversaries, at least on legislation that appeals to her base

She has attributed the success of these efforts at least in part to her role as the second most powerful Democrat on the House Oversight Committee, which she said has “opened many windows” for collaboration.

while these bills may seem like small victories, they are more than that because, in a sense, she is redefining what bipartisanship looks like in Washington.

For decades, bipartisanship has meant bringing together moderates, lobbyists and establishment insiders to produce watered-down legislation unpalatable to many voters in both political partie

What Ms. Ocasio-Cortez is doing is different; she’s uniting politicians on the fringes of American politics around a broadly popular set of policies.

Americans in both parties overwhelmingly say that they don’t trust the government to do the right thing and that donors and lobbyists have too much sway over the legislative process.

more than 8 in 10 Americans believe politicians “are more focused on fighting each other than on solving problems.” One-fifth of respondents said lack of bipartisan cooperation was the biggest problem with the political system.

Ms. Ocasio-Cortez’s efforts to reach out to Republicans are offering what a sizable portion of Americans want from Congress: a return to getting things done.

The few policy matters on which progressives and conservatives align often boil down to a distrust of politicians and of big corporations, particularly technology companies and pharmaceutical giants.

Ms. Ocasio-Cortez has shrewdly made those causes her passion, building alliances with conservative colleagues interested in holding these industries accountable.

Last spring, she cosponsored a bill with, among others, Brian Fitzpatrick, a moderate Republican from Pennsylvania, and Matt Gaetz, the Florida rabble-rouser who has become one of Mr. Trump’s most steadfast allies. The legislation would bar members of Congress from trading individual stocks, a measure that as of the fall of 2022 was supported by nearly 70 percent of voters across party lines.

On Gaza, too, she has been willing to buck other members of her party to pursue an agenda that a majority of voters support. She was one of the first Democrats to call for a cease-fire; within weeks, nearly 70 percent of Americans said Israel should call one and try to negotiate with Hamas.

In March, Ms. Ocasio-Cortez was accosted by a handful of protesters who demanded that she call Israel’s war in Gaza a genocide.

Less than three weeks later, Ms. Ocasio-Cortez did accuse Israel of genocide and chastised the White House for providing military aid to the country while it blockaded Gaza. “If you want to know what an unfolding genocide looks like,” Ms. Ocasio-Cortez said in a speech on the House floor, “open your eyes. It looks like the forced famine of 1.1 million innocents. It looks like thousands of children eating grass as their bodies consume themselves, while trucks of food are slowed and halted just miles away.”

Last month, she voted against providing additional funding for Israel. Those were unpopular positions in Congress, where unconditional support for the country remains the norm, but they put her in line with a majority of Democratic voters.

These stances haven’t been enough to quell the doubts from a faction of the left that helped get her elected. Over the past few weeks, some have accused her of caving in to pressure from moderate Democrats

. Ms. Ocasio-Cortez has taken much of the heat from leftist activists who see her as a symbol of the contradictions and compromises inherent in the political system. It may not be realistic to expect absolute purity from her; she is, after all, a politician. But these critiques overlook the promise of what she’s doing behind the scenes.

Democratic pollsters and strategists are searching for ways for Mr. Biden to win back Muslims and Arab Americans in swing states such as Michigan and Georgia, recent college graduates who hoped to have their student debt forgiven, immigrant-rights activists and Latinos.

Some of the betrayal these voters feel was hardly the president’s fault; he was hampered on student loan debt by a federal judiciary stacked with judges sympathetic to conservative legal arguments, and Congress refused to pass the comprehensive immigration bill he supported in 2021, which would have provided legal status to as many as 11 million undocumented immigrants.

A more gifted orator might have been able to make the structural impediments in his way clear to voters, while also putting forth a proactive vision for dismantling the core problems baked into our politics.

In that, someone like Ms. Ocasio-Cortez, who endorsed Mr. Biden for re-election in 2023, may be able to help. She’s the Democratic Party’s most charismatic politician since Barack Obama and its most ardent populist since Bernie Sanders.

she can offer voters something more substantial than a hollow rebuke of Trumpism

Last month, when the journalist Mehdi Hasan asked her how she’d respond to “a young progressive or Arab American who says to you, ‘I just can’t vote for Biden again after what he’s enabled in Gaza,’” Ms. Ocasio-Cortez said a vote for Mr. Biden didn’t necessarily mean an endorsement of all his policies. “Even in places of stark disagreement, I would rather be organizing under the conditions of Biden as an opponent on an issue than Trump,” she said. It was a shrewd political maneuver, designed to distance herself from Democrats who support Israel unconditionally, while meeting voters — some of whom have lost family members in Gaza — where they are

There are, of course, limits to this strategy. Some on the left see Ms. Ocasio-Cortez’s endorsement of Mr. Biden as a betrayal of progressive values, particularly in the wake of the climbing death toll in Gaza.

The moderate Republicans who turned out for Mr. Biden in 2020 might shrink from a Democratic Party led by someone they consider an outspoken progressive.

But for every moderate or leftist voter lost with a strategy like Ms. Ocasio-Cortez’s, the Democratic Party may be able to win someone new — from the pool of disillusioned Americans who feel shut out of the political process.

it is not just that Europeans spend a few extra weeks on the beach. The typical working day in Britain, France and Germany is half an hour shorter than in America, according to the International Labour Organisation.

which is the better way of living—with more money or more free time? The reality is that it is difficult for people to choose

Those in America work according to American schedules; those in Europe conform to European norms.

the more fruitful question is why Americans put in longer hours

The answer leads to a curious new observation: that remote work is making America’s office drones a little more European, albeit with a puritanical twist.

A first guess suggests that culture might account for the variation in work hours. Maybe Europeans enjoy their leisure more. They are spoilt for choice about how to spend time off

As for Americans, surveys indicate that they view hard work as intrinsically worthwhile. “Rugged individualism” is, after all, what built the country.

the difficulty with chalking up the difference to culture is that until the early 1970s many Europeans worked more

American working hours are basically the same now as back then. The big change is that Europeans now toil less. Hours are down a whopping 30% in Germany over the past half-century. Something beyond culture—a slow-moving, ill-defined variable—is at play.

Edward Prescott, an American economist, came to a provocative conclusion, arguing that the key was taxation

Until the early 1970s tax levels were similar in America and Europe, and so were hours worked. By the early 1990s Europe’s taxes had become more burdensome and, in Prescott’s view, its employees less motivated

A substantial gap persists today: American tax revenue is 28% of GDP, compared with 40% or so in Europe.

A recent study by Jósef Sigurdsson of Stockholm University examined how Icelandic workers responded to a one-year income-tax holiday in 1987, when the country overhauled its tax system. Although people with more flexibility—especially younger ones in part-time jobs—did indeed put in more hours, the overall increase in work was modest relative to that implied by Prescott’s model.

Regulation seems to matter more.

European rules give workers power, from generous parental-leave policies to stricter laws on firing staff. Many European countries try to put caps on working tim

most research agrees that they have reduced work hours.

Another important relationship is that, as people get richer, they typically want to work less

A recent paper by the IMF shows a remarkably strong link between GDP per person and hours worked in Europe. People in richer countries, such as the Netherlands, generally work less than those in poorer countries, such as Bulgaria.

Americans are wealthier than most Europeans, so why do they still work more?

Perhaps leisure is a collective-action problem. Americans may want to ask their bosses for longer holidays but are worried about being seen as slackers

A paper in 2005 by Alberto Alesina of Harvard University and colleagues argued that Europe’s stronger unions had in effect solved this collective-action problem by fighting for paid vacations, which ended up enshrined in law.

Europe’s well-regulated leisure time may then beget more leisure because it is more socially acceptable, and the market responds by supplying more good ways not to work. It is a virtuous cycle of lovely cafés.

One fascinating new development is a discrepancy in the rise of remote work

In 2023 the Global Survey of Working Arrangements found that full-time employees in America work from home 1.4 days a week, while those in Europe do so for 0.8 days

a striking result: Europeans and Americans now spend almost exactly the same amount of time in the office, with 1,320 hours a year for the former and 1,304 for the latter.

In other words, the extra 15% of work done by Americans annually is now from the comfort of their own homes—or occasionally on the beach, perhaps even one in Europe. Americans do still work harder, but rather more enjoyably than in the past

Firewalls around the engines, nitrogen pumps in fuel tanks that help prevent immediate burning, and fire-resistant materials on seats and flooring most likely helped to keep the rising flames at bay, said Sonya A. Brown, a senior lecturer in aerospace design at the University of New South Wales in Sydney, Australia.

“Really, the Japan Airlines crew in this case performed extremely well,” Dr. Brown said. The fact that passengers did not stop to retrieve carry-on luggage or otherwise slow down the exit was “really critical,” she added.

Tadayuki Tsutsumi, an official at Japan Airlines, said the most important component of crew performance during an emergency was “panic control” and determining which exit doors were safe to use.

Former flight attendants described the rigorous training and drills that crew members undergo to prepare for emergencies. “When training for evacuation procedures, we repeatedly used smoke/fire simulation to make sure we could be mentally ready when situations like those occurred in reality,” Yoko Chang, a former cabin attendant and an instructor of aspiring crew members, wrote in an Instagram message.

Ms. Chang, who did not work for JAL, added that airlines require cabin crew members to pass evacuation exams every six months.

But only a handful of cancers—of the breast, lung, colon and cervix—have screening tests recommended by the U.S. Preventive Services Task Force

Many companies are developing blood tests that can detect cancer signals before symptoms occur, and Grail’s is the most advanced. A study found it can identify more than 50 types of cancer 52% of the time and the 12 deadliest cancers in Stages I through III 68% of the time.

There’s a hitch. The test costs $949 and isn’t covered by Medicare or most private insurance.

The trouble is that this cancer is almost never caught early. There’s no routine screening for it, and symptoms don’t develop until it is advanced. Mr. Royse, 64, had no idea he was sick until he took a blood test called Galleri, produced by the Menlo Park, Calif., startup Grail. He had surgery and chemotherapy and is now cancer-free.

Mr. Royse visited Grail’s website, which referred him to a telemedicine provider who ordered a test. Another telemedicine doctor walked him through his results, which showed a cancer signal likely emanating from the pancreas, gallbladder, stomach or esophagus.

An MRI revealed a suspicious mass on his pancreas, which a biopsy confirmed was cancerous. Mr. Royse had three months of chemotherapy, surgery and another three months of chemotherapy, which ended last February. Because pancreatic cancer often recurs, he gets CT and MRI scans every three months. In addition, he has signed up for startup Natera’s Signatera customized blood test, which checks DNA specific to the patient’s cancer and can signal its return before signs are visible on the scans

Grail’s test likewise looks for DNA shed by cancer cells, which is tagged by molecules called methyl groups that are specific to a cancer’s origin. Grail uses genetic sequencing and machine learning to recognize links between DNA methyl groups and particular cancers

The test “is based on how much DNA is being shed by tumor,” Grail’s president, Josh Ofman, says. “Some tumors shed a lot of DNA. Some shed almost none.

ut slow-growing tumors typically aren’t shedding a lot of DNA.” That reduces the probability that Grail’s test will identify indolent cancers that pose no immediate danger.

Grail’s test has a roughly 0.5% false-positive rate, meaning 1 in 200 patients who don’t have cancer will get a positive signal

Its positive predictive value is 43%, so that of every 100 patients with a positive signal, 43 actually have cancer

the legislation’s price tag could reduce political support. According to one private company’s estimate, the test could cost the government $39 billion to $145 billion over a decade. Mr. Goldman counters that analysts usually overestimate the costs and underestimate the benefits of medical interventions.

Because Grail uses machine learning to detect DNA-methylation cancer linkages, the Grail test’s accuracy should improve as more tests and patient data are collected

regulators may balk at approving the test, and insurers at covering it, until it becomes cheaper and more reliable.

How would the FDA weigh the risk that a false positive on a test like Grail’s could require invasive follow-up testing against the dire but hard-to-quantify risk that a deadly cancer wouldn’t be caught until it’s much harder to treat? It’s unclear.

some experts urge the FDA to require large randomized controlled trials before approving blood cancer tests. “Multicancer screening would entail tremendous costs and potentially substantial harms,” H. Gilbert Welch and Tanujit Dey of Brigham and Women’s Hospital wrote

Dr. Welch and Mr. Dey also suggested that companies should be required to prove their tests reduce overall mortality, even though the FDA doesn’t require drugmakers to prove their products reduce deaths or extend life. Clinical trials for the mRNA Covid vaccines didn’t show they reduced deaths.

One alternative is to rely on real-world studies, which Grail is already doing. One study of patients 50 and older without signs of cancer showed that the test doubled the number of cancers detected.

One recurring problem he has seen: “Epidemiologists are always getting cancer wrong,” he says. “Epidemiologists a decade ago said U.S. overtreats cancers. Well, no, the EU undertreats cancer.”

A 2012 study that he co-authored found that the higher U.S. spending on cancer care relative to Europe between 1983 and 1999 resulted in significantly higher survival rates for American patients than for those in Europe

By his study’s calculation, U.S. spending on cancer treatments during that period resulted in $556 billion in net benefits owing to reduced mortality.

He expects Galleri and other multicancer early-detection tests to reduce deaths and produce public-health and economic benefits that exceed their monetary costs

Expanding access to multicancer early-detection tests could also help solve the chicken-and-egg problem of drug development. Because few patients are diagnosed at early stages of some cancers, it’s hard to develop treatments for them

the positive predictive value for some recommended cancer screenings is far lower. Fewer than 1 in 10 women with an abnormal finding on a mammogram are diagnosed with breast cancer.

Mr. Royse makes the same point with personal force. “I would be dead right now if not for multicancer early-detection testing,” Mr. Royse told an FDA advisory committee last fall. “The longer the FDA waits, the more people are going to die. It’s that simple.”

“So far we’re seeing basic agreement with our best model of the universe, but we’re also seeing some potentially interesting differences that could indicate that dark energy is evolving with time,”

When the scientists combined their map with other cosmological data, they were surprised to find that it did not quite agree with the otherwise reliable standard model of the universe, which assumes that dark energy is constant and unchanging. A varying dark energy fit the data points better.

“It’s certainly more than a curiosity,” Dr. Palanque-Delabrouille said. “I would call it a hint. Yeah, it’s not yet evidence, but it’s interesting.”

But this version of dark energy is merely the simplest one. “With DESI we now have achieved a precision that allows us to go beyond that simple model,” Dr. Palanque-Delabrouille said, “to see if the density of dark energy is constant over time, or if it has some fluctuations and evolution with time.”

“While combining data sets is tricky, and these are early results from DESI, the possible evidence that dark energy is not constant is the best news I have heard since cosmic acceleration was firmly established 20-plus years ago.”

praised the new survey as “superb data.” The results, she said, “open the potential for a new window into understanding dark energy, the dominant component of the universe, which remains the biggest mystery in cosmology. Pretty exciting.”

what if dark energy were not constant as the cosmological model assumed?

At issue is a parameter called w, which is a measure of the density, or vehemence, of the dark energy. In Einstein’s version of dark energy, this number remains constant, with a value of –1, throughout the life of the universe. Cosmologists have been using this value in their models for the past 25 years.

Dark energy took its place in the standard model of the universe known as L.C.D.M., composed of 70 percent dark energy (Lambda), 25 percent cold dark matter (an assortment of slow-moving exotic particles) and 5 percent atomic matter. So far that model has been bruised but not broken by the new James Webb Space Telescope

As a measure of distance, the researchers used bumps in the cosmic distribution of galaxies, known as baryon acoustic oscillations. These bumps were imprinted on the cosmos by sound waves in the hot plasma that filled the universe when it was just 380,000 years old. Back then, the bumps were a half-million light-years across. Now, 13.5 billion years later, the universe has expanded a thousandfold, and the bumps — which are now 500 million light-years across — serve as convenient cosmic measuring sticks.

The DESI scientists divided the past 11 billion years of cosmic history into seven spans of time. (The universe is 13.8 billion years old.) For each, they measured the size of these bumps and how fast the galaxies in them were speeding away from us and from each other.

When the researchers put it all together, they found that the usual assumption — a constant dark energy — didn’t work to describe the expansion of the universe. Galaxies in the three most recent epochs appeared closer than they should have been, suggesting that dark energy could be evolving with time.

Dr. Riess of Johns Hopkins, who had an early look at the DESI results, noted that the “hint,” if validated, could pull the rug out from other cosmological measurements, such as the age or size of the universe. “This result is very interesting and we should take it seriously,” he wrote in his email. “Otherwise why else do we do these experiments?”

“China is clearly alarmed by these developments,” said Jingdong Yuan, director of the China and Asia Security Program at the Stockholm International Peace Research Institute. “Chinese interpretations would be that the U.S. and its allies have clearly decided that China needs to be contained.”

aside from pointed words and the perfunctory maritime patrol, Beijing’s options to push back against U.S. pressure appear limited, analysts said, especially as China contends with slowing economic growth and mounting trade frictions.

Whether Mr. Biden’s strategy succeeds in deterring China in the long run remains to be seen. Nationalists in China view American alliances as fragile and subject to the whims of each U.S. presidential election. Then there’s Mr. Xi, who perceives the West to be in structural decline, and China’s ascendance as Asia’s dominant power to be inevitable.

“The Americans should not think so highly of themselves. They could not solve Afghanistan or Ukraine,” said Zheng Yongnian, an influential political scientist at the Chinese University of Hong Kong’s campus in Shenzhen. He said that China still hoped to resolve its disputes peacefully. “The reason we are not touching the Philippines is not that we are afraid of the United States.”

Beijing’s room to maneuver against Washington is limited by its struggling economy, which has been hit by a property crisis and a cratering of foreign investment. China has been increasing exports, but that has already caused friction with countries concerned about a flood of cheap Chinese goods.

The broader American pressure campaign may also be nudging China to avoid escalating tensions further. Despite its differences with the United States, China is engaging in talks between the countries’ leaders and senior officials. Relations with some neighbors, such as Australia, are slowly thawing. Analysts have noted that Beijing has also avoided escalating its military presence around Taiwan in recent months, despite the island’s election of a leader the Communist Party loathes.

“They are definitely being more cautious and demonstrating a willingness to engage,” Ja Ian Chong, an associate professor of political science at the National University of Singapore, said of Beijing. “They are realizing there are actual risks to letting frictions escalate. We just haven’t seen any substantive compromises yet.”

“We have an outstanding mayor, who is committed to tackling climate change. She said the 15-minute city will be the backbone for creating a new urban plan. The last time Paris had a new urban plan was in 2000, so this road map will be relevant for the next 10 or 15 years at least,”

“I said to Hidalgo, the 15-minute city is not an urban traffic plan. The 15-minute city is a radical change of our life.”

He also thinks office should generally be closer to homes, as well as cultural venues, doctors, shops and other amenities. Shared spaces such as parks help the people living in the areas to form communities.

They have also often been segmented into wealthier and poorer areas; in the less prosperous area to the north-east of Paris, Moreno says up to 40% of homes are social housing. In the wealthier west of Paris, this drops below 5%.

“My idea is to break this triple segregation,” he says.

Moreno thinks this segregation leads to a poorer quality of life, one designed around outdated “masculine desires”, so his proposal is to mix this up, creating housing developments with a mixture of social, affordable and more expensive housing so different social strata can intermingle

He also wants to bring schools and children’s areas closer to work and home, so caregivers can more easily travel around and participate in societ

When many modern cities were designed, they were for men to work in. Their wives and family stayed in the suburbs, while the workers drove in. So they have been designed around the car, and segmented into different districts: the financial district (think Canary Wharf), the cultural area (for example, the West End) and then the suburbs

The city has also been regenerating the Clichy-Batignolles district in the less prosperous north-west of Paris to have a green, village-like feel. About a quarter of it is taken up by green space and a new park.“As a 15-minute district, it is incredible,” says Moreno. “It is beautiful, it has proximity, social mixing, 50% of the inhabitants live in social housing, 25% in middle class and 25% own their homes.”

Many of his proposals are dear to the culture of the French. In a large, wealthy metropolis such as Paris, it is easy for small shops to be choked out by large chains. The city of Paris, in its new plan, has put measures in to stop this.

“We have a commercial subsidiary of the city of Paris which has put €200m into managing retail areas in the city with rates below the speculative real estate market. This is specifically to rent to small shops, artisans, bakeries, bookstores.

This is not only a good investment because it creates a good economic model, but it keeps the culture of the city of Paris,”

This is in keeping with the 15-minute city plan as it keeps local shops close to housing, so people can stroll down from their apartment to pick up a fresh baguette from an independent baker. “It creates a more vibrant neighbourhood,” he adds.

Hidalgo inevitably faced a large backlash from the motorist lobby. Stroll down the banks of the Seine today in the new protected parks and outdoor bars, and it is hard to imagine that it was recently a traffic-choked highway

“The drivers were radically very noisy, saying that we wanted to attack their individual rights, their freedom. The motorist lobby said she cannot be elected without our support, that they are very powerful in France,” Moreno says. But Hidalgo called their bluff: “She often says ‘I was elected two times, with the opposition of the automotive lobby’. In 2024, nobody requests to open again the highway on the Seine, no one wants the Seine urban park to be open for cars.”

Moreno talks about the concept of a “giant metronome of the city” which causes people to rush around. He wants to slow this down, to allow people to reclaim their “useful time” back from commuting and travelling to shops and cultural areas.

“I bet for the next year, for the next decade, we will have this new transformation of corporation real estate,” he says. “Businesses are choosing multi-use areas with housing, schools, shops for their office space now. The time of the skyscrapers in the masculine design is finished.”

Republican politicians, sensing momentum, called on other firms to follow suit.

“This was always cosmetic,” said Shivaram Rajgopal, a professor at Columbia Business School. “If signing a piece of paper was getting these companies into trouble, it’s no surprise they’re getting the hell out.

American asset managers have a fiduciary duty to act in the best interest of their clients, and the financial firms were worried that a new strategy by Climate Action 100+ could expose them to legal risks.

Since its founding in 2017, the group focused on getting publicly traded companies to increase how much information they shared about their emissions and identify climate-related risks to their businesses.

In addition to the risk that some clients might disapprove, and potentially sue, there were other concerns. Among them: that acting in concert to shape the behaviors of other companies could fall afoul of antitrust regulations.

The new plan called on asset-management firms to begin pressuring companies like Exxon Mobil and Walmart to adopt policies that could entail, for example, using fewer fossil fuels

last year, Climate Action 100+ said it would shift its focus toward getting companies to reduce emissions with what it called phase two of its strategy

BlackRock also said that one of its subsidiaries, BlackRock International, would continue to participate in the group — a tacit acknowledgment of the different regulatory environment in Europe. BlackRock also said it was initiating new features that would let clients choose if they wanted to pressure companies to reduce their emissions.

Pimco, another big asset manager, followed suit. “We have concluded that our Climate Action 100+ participation is no longer aligned with PIMCO’s approach to sustainability,” a firm spokesman said in a statement.

JPMorgan said it was pulling out of the group in recognition of the fact that, over the past few years, the firm had developed its own framework for engaging on climate risk

The fracturing of Climate Action 100+ was a victory for Representative Jim Jordan, Republican of Ohio, who has led a campaign against companies pursuing E.S.G. goals, shorthand for environmental, social and governance factors.

Embracing E.S.G. principles and speaking up on climate issues has become commonplace across corporate America in recent years. Chief executives warned about the dangers of climate change. Banks and asset managers formed alliances to phase out fossil fuels. Trillions of dollars were allocated for sustainable investing.

“Phase two is not that different,” she said. “It’s basically investors working with companies and saying: ‘OK, you’ve disclosed the risk. We just want to know how you’re going to address it.’ Because that’s what the investors want. How are you dealing with risk?”

Mindy Lubber, the chief executive of Ceres and a member of the steering committee of Climate Action 100+, disputed the notion that the new strategy represented a change from the focus on enhanced disclosure.

“The political cost has heightened, the legal risk has heightened,” he said. “That said, these corporations are not doing U-turns,” he added. “They continue to consider climate. That’s not going away. It’s adapting to the current environment.”

Aron Cramer, chief executive for BSR, a sustainable-business consultancy, said the Wall Street firms were responding to political pressure, but not abandoning their climate commitments altogether.

Several of the firms that backed out of Climate Action 100+ said they remained committed to the issue. JPMorgan said that it had a team of 40 people working on sustainable investing and that it believed “climate change continues to present material economic risks and opportunities to our clients.”

Mensch said his new model cost less than €20 million, the equivalent of roughly $22 million, to train. By contrast OpenAI Chief Executive Sam Altman said last year after the release of GPT-4 that training his company’s biggest models cost “much more than” $50 million to $100 million.

Brave Software made a free, open-source model from Mistral the default to power its web-browser chatbot, said Brian Bondy, Brave’s co-founder and chief technology officer. He said that the company finds the quality comparable with proprietary models, and Mistral’s open-source approach also lets Brave control the model locally.

“We want to be the most capital-efficient company in the world of AI,” Mensch said. “That’s the reason we exist.” 

Mensch joined the Google AI unit then called DeepMind in late 2020, where he worked on the team building so-called large language models, the type of AI system that would later power ChatGPT. By 2022, he was one of the lead authors of a paper about a new AI model called Chinchilla, which changed the field’s understanding of the relationship among the size of an AI model, how much data is used to build it and how well it performs, known as AI scaling laws.

Mensch took a role lobbying French policymakers, including French President Emmanuel Macron, against certain elements of the European Union’s new AI Act, which Mensch warned could slow down companies and would, in his view, do nothing to make AI safer. After changes to the text in Brussels, it will be a manageable burden for Mistral, Mensch says, even if he thinks the law should have remained focused on how AI is used rather than also regulating the underlying technology.  

For Mensch and his co-founders, releasing their initial AI systems as open source that anyone could use or adapt free of charge was an important principle. It was also a way to get noticed by developers and potential clients eager for more control over the AI they use

Mistral’s most advanced models, including the one unveiled Monday, aren’t available open source. 

Fresh estimates from the Congressional Budget Office this month said the U.S. labor force in 2023 had grown by 5.2 million people, thanks especially to net immigration

The sudden snapback in demand sent inflation soaring. Supply chain issues were a main reason prices rose quickly. But labor shortages posed a problem, too, and economists feared that rising wages — as employers scrambled to find workers — would keep price increases dangerously high.

he flow of migrants to the United States started slowing during the Trump administration, when officials took hundreds of executive actions designed to restrict migration.

Right before the pandemic, there were about 1.5 million fewer working-age immigrants in the United States than pre-2017 trends would have predicted, according to the San Francisco Fed. By the end of 2021, that shortfall had widened to about 2 million

But the economy overall wound up rebounding aggressively from the sudden, widespread closures of 2020, bolstered by historic government stimulus and vaccines that debuted faster than expected.

economy grow. But today’s snapshot still represents a stark turnaround from just a short time ago.

That’s because the labor force that emerged as the pandemic ebbed was smaller than it had been: Millions of people retired early, stayed home to take over child care or avoid getting sick, or decided to look for new jobs entirely

In the span of a year or so, employers went from having businesses crater to sprinting to hire enough staff to keep restaurants, hotels, retail stores and construction sites going. Wages for the lowest earners rose at the fastest pace.

About the same time, the path was widening for migrants to cross the southern border, particularly as the new Biden administration rolled back Trump-era restrictions.

Experts argue that the strength of the U.S. economy has benefited American workers and foreign-born workers alike. Each group accounts for roughly half of the labor market’s impressive year-over-year growth since January 2023

But the past few years were extremely abnormal because companies were desperate to hire.

lus, it would be exceedingly difficult for immigration to affect the wages of enormous swaths of the labor force,

“What it can do is lower the wages of a specific occupation in a specific area, but American workers aren’t stupid. They change jobs. They change what they specialize in,” Nowrasteh said. “So that’s part of the reason why wages don’t go down.”

In normal economic times, some analysts note, new immigrants can drag down wages, especially if employers decide to hire them over native-born workers. Undocumented workers, who don’t have as much leverage to push for higher pay, could lower average wages even more.

Particularly for immigrants fleeing poorer countries, the booming U.S. job market and the promise of higher wages continue to be an enormous draw.

“More than any immigration policy per se, the biggest pull for migrants is the strength of the labor market,” said Catalina Amuedo-Dorantes, an economics professor at the University of California at Merced. “More than any enforcement policy, any immigration policy, at the end of the day.”

Upon arriving in Denver in October, Santander hadn’t acquired a work permit but needed to feed his small children. Even without authorization, he found a job as a roofer for a contractor that ultimately pocketed his earnings, then one cleaning industrial refrigerators on the overnight shift for $12 an hour. Since receiving his work permit in January, Santander has started “a much better job” at a wood accessories manufacturer making $20 an hour.

But for the vast majority of migrants who arrive in the United States without prior approval, including asylum seekers and those who come for economic reasons, getting a work permit isn’t easy.

Federal law requires migrants to wait nearly six months to receive a work permit after filing for asylum. Wait times can stretch for additional months because of a backlog in cases.

While they wait, many migrants find off-the-books work as day laborers or street vendors, advocates say. Others get jobs using falsified documents, including many teenagers who came into the country as unaccompanied minors.

Still, many migrants miss the year-long window to apply for asylum — a process that can cost thousands of dollars — leaving them with few pathways to work authorization, advocates say. Those who can’t apply for asylum often end up working without official permission in low-wage industries where they are susceptible to exploitation.

Reading their books, he tells us, can be as exciting as reading a great novel or poem. In particular, Krishnan emphasizes the virtues they embodied in themselves and their work. “Some of these virtues were, by any reckoning, moral ones: humility, self-awareness, collegiality, restraint. Others are better thought aesthetic: elegance, concision, directness.”

Consider Gilbert Ryle. As the Waynflete professor of metaphysics, he was asked if he ever read novels, to which he replied, “All six of them, once a year.” Jane Austen’s, of course.

Another time, an American visitor wondered if it was true that Ryle, as editor of the journal Mind, would “accept or reject an article on the basis of reading just the first paragraph.” “That used to be true at one time,” Ryle supposedly answered. “I had a lot more time in those days.”

J.L. Austin gradually emerges as the central figure. “He listened, he understood, and when he started to speak, with the piercing clarity he brought to all things, philosophical or not, it ‘made one’s thoughts race.’”

Oxford discussion groups and tutorials tried to avoid those “cheap rhetorical ploys” that aim “at victory and humiliation rather than truth.” Instead their unofficial motto stressed intellectual fraternity: “Let no one join this conversation who is unwilling to be vulnerable.”

their meetings continually resounded with “short, punchy interrogations” that aimed “to clarify positions, pose objections and expose inconsistencies.”

Austin “wanted to be, all he wanted other people to be, was rational.” His highest praise was to call someone “sensible.”

When Oxford announced plans to award Truman an honorary degree, Anscombe objected. She wasn’t protesting against nuclear weapons per se (as was Bertrand Russell) but simply standing up for what she regarded as an inviolable principle: “Choosing to kill the innocent as a means to your ends is always murder.” End of argument. Anscombe’s was a lonely voice, however, except for the support of her philosopher friend, Philippa Foot, whose imposing manner Krishnan brilliantly captures: “She looked like the sort of young woman who knew how to get a boisterous dog to sit.”

Despite the sheer entertainment available in “A Terribly Serious Adventure,” readers will want to slow down for its denser pages outlining erudite theories or explaining category mistakes and other specialized terms

All these philosophers, as well as a half-dozen others I haven’t been able to mention, come across as both daunting and charismatic

Before the pandemic, a number of variables were statistically significant indicators for consumer sentiment in our model; in particular, the most salient variables appear to be vehicle sales, gas prices, median household income, the federal funds effective rate, personal savings and household expenditures (excluding food and energy).

During the pandemic, the personal savings rate soared. In April 2020, the metric was nearly double its previous high, recorded in May 1975.

All this taken together meant Americans were flush with cash but had nowhere to spend it. So despite the fact that the savings rate went way up, consumers still weren't feeling positively about the economy — contrary to the relationship between these two variables we saw in the decades before the pandemic.

Fast forward to 2024, and the personal savings rate has dropped to one of its lowest levels ever (the only time the savings rate was lower was in the years surrounding the Great Recession)

during and after the pandemic, Americans saw some of the highest rates of inflation the country has had in decades, and in a very short period of time. These sudden spikes naturally shocked many people who had been blissfully enjoying slow, steady price growth their entire adult lives. And it has taken a while for that shock to wear off, even as inflation has cre

the numbers align with our intuitive sense of how consumers process suddenly having their grocery store bill jump, as well as the findings from our model. In simple terms: Even if inflation is getting better, Americans aren't done being ticked off that it was bad to begin with.

surprisingly, our pre-pandemic model didn't find a notable relationship between housing prices and consumer sentiment

However, in our post-pandemic data, when we examined how correlated consumer sentiment was with each indicator we considered, consumer sentiment and median housing prices had the strongest correlation of all****** (a negative one, meaning higher prices were associated with lower consumer sentiment)

during the pandemic, low interest rates, high savings rates and changes in working patterns — namely, many workers' newfound ability to work from home — helped overheat the homebuying market, and buyers ran headlong into an enduring supply shortage. There simply weren't enough houses to buy, which drove up the costs of the ones that were for sale.

That's true even if a family has been able to save enough for a down payment, already a difficult task when rents remain high as well. Fewer people are able to cover their current housing costs while saving enough to make a down payment.

Low-income households are still the most likely to be burdened with high rents, but they're not the only ones affected anymore. High rents have also begun to affect those at middle-income levels as well.
