it is easy to forget how much we have in common as people. I can’t think of any major nation after the United States with more of a Protestant work ethic and naturally capitalist population than China.

These days, it is extremely difficult for a visiting columnist to get anyone — a senior official or a Starbucks barista — to speak on the record. It was not that way a decade ago.

The Communist Party’s hold is also a product of all the hard work and savings of the Chinese people, which have enabled the party and the state to build world-class infrastructure and public goods that make life for China’s middle and lower classes steadily better.

Beijing and Shanghai, in particular, have become very livable cities, with the air pollution largely erased and lots of new, walkable green spaces.

some 900 cities and towns in China are now served by high-speed rail, which makes travel to even remote communities incredibly cheap, easy and comfortable

Just when trust has become more important than ever between the U.S. and China, it also has become scarcer than ever. Bad trend.

China’s stability is a product of both an increasingly pervasive police state and a government that has steadily raised standards of living. It’s a regime that takes both absolute control and relentless nation-building seriously.

For an American to fly from New York’s Kennedy Airport into Beijing Capital International Airport today is to fly from an overcrowded bus terminal to a Disney-like Tomorrowland.

China got an early jump on A.I. in two realms — facial recognition technology and health records — because there are virtually no privacy restrictions on the government’s ability to build huge data sets for machine learning algorithms to find patterns.

“ChatGPT is prompting some people to ask if the U.S. is rising again, like in the 1990s,”

“I understand your feeling: You have been in the first place for a century, and now China is rising, and we have the potential to become the first — and that is not easy for you,” Hu said to me. But “you should not try to stop China’s development. You can’t contain China in the end. We are quite smart. And very diligent. We work very hard. And we have 1.4 billion people.”

Before the Trump presidency, he added: “We never thought China-U.S. relations would ever become so bad. Now we gradually accept the situation, and most Chinese people think there is no hope for better relations. We think the relationship will be worse and worse and hope that war will not break out between our two countries.”

A lot of people hesitated when I asked. Indeed, many would answer with some version of “I’m not sure, I just know that it’s THEIR fault.”

t was repeated conversations like these that got me started asking American, Chinese and Taiwanese investors, analysts and officials a question that has been nagging at me for a while: What exactly are America and China fighting about?

the real answer is so much deeper and more complex than just the usual one-word response — “Taiwan” — or the usual three-word response — “autocracy versus democracy.”

Let me try to peel back the layers. The erosion in U.S.-China relations is a result of something old and obvious — a traditional great-power rivalry between an incumbent power (us) and a rising power (China) — but with lots of new twists

One of the twists, though, is that this standard-issue great-power rivalry is occurring between nations that have become as economically intertwined as the strands of a DNA molecule. As a result, neither China nor America has ever had a rival quite like the other.

in modern times, China, like America, has never had to deal with a true economic and military peer with which it was also totally intertwined through trade and investment.

Another new twist, and a reason it’s hard to define exactly what we’re fighting about, has a lot to do with how this elusive issue of trust and the absence of it have suddenly assumed much greater importance in international affairs.

This is a byproduct of our new technological ecosystem in which more and more devices and services that we both use and trade are driven by microchips and software, and connected through data centers in the cloud and high-speed internet

so many more things became “dual use.” That is, technologies that can easily be converted from civilian tools to military weapons, or vice versa.

no one country or company can own the whole supply chain. You need the best from everywhere, and that supply chain is so tightly intertwined that each company has to trust the others intimately.

when we install the ability to sense, digitize, connect, process, learn, share and act into more and more things — from your GPS-enabled phone to your car to your toaster to your favorite app — they all become dual use, either weapons or tools depending on who controls the software running them and who owns the data that they spin off.

As long as most of what China sold us was shallow goods, we did not care as much about its political system — doubly so because it seemed for a while as if China was slowly but steadily becoming more and more integrated with the world and slightly more open and transparent every year. So, it was both easy and convenient to set aside some of our worries about the dark sides of its political system.

when you want to sell us ‘deep goods’ — goods that are dual use and will go deep into our homes, bedrooms, industries, chatbots and urban infrastructure — we don’t have enough trust to buy them. So, we are going to ban Huawei and instead pay more to buy our 5G telecom systems from Scandinavian companies we do trust: Ericsson and Nokia.”

as we’ve seen in Ukraine, a smartphone can be used by Grandma to call the grandkids or to call a Ukrainian rocket-launching unit and give it the GPS coordinates of a Russian tank in her backyard.

So today, the country or countries that can make the fastest, most powerful and most energy efficient microchips can make the biggest A.I. computers and dominate in economics and military affairs.

As more and more products and services became digitized and electrified, the microchips that powered everything became the new oil. What crude oil was to powering 19th- and 20th-century economies, microchips are for powering 21st-century economies.

When you ask them what is the secret that enables TSMC to make 90 percent of the world’s most advanced logic chips — while China, which speaks the same language and shares the same recent cultural history, makes zero — their answer is simple: “trust.”

TSMC is a semiconductor foundry, meaning it takes the designs of the most advanced computer companies in the world — Apple, Qualcomm, Nvidia, AMD and others — and turns the designs into chips that perform different processing functions

TSMC makes two solemn oaths to its customers: TSMC will never compete against them by designing its own chips and it will never share the designs of one of its customers with another.

“Our business is to serve multiple competitive clients,” Kevin Zhang, senior vice president for business development at TSMC, explained to me. “We are committed not to compete with any of them, and internally our people who serve customer A will never leak their information to customer C.”

But by working with so many trusted partners, TSMC leverages the partners’ steadily more complex designs to make itself better — and the better it gets, the more advanced designs it can master for its customers. This not only requires incredibly tight collaboration between TSMC and its customers, but also between TSMC and its roughly 1,000 critical local and global suppliers.

As the physics of chip making gets more and more extreme, “the investment from customers is getting bigger and bigger, so they have to work with us more closely to make sure they harvest as much [computing power] as they can. They have to trust you.”

China also has a foundry, Semiconductor Manufacturing International Corporation, which is partly state-owned. But guess what? Because no global chip designers trust SMIC with their most advanced designs, it is at least a decade behind TSMC.

It’s for these reasons that the erosion in U.S.-China relations goes beyond our increasingly sharp disagreements over Taiwan. It is rooted in the fact that just when trust, and its absence, became much bigger factors in international affairs and commerce, China changed its trajectory. It made itself a less trusted partner right when the most important technology for the 21st century — semiconductors — required unprecedented degrees of trust to manufacture and more and more devices and services became deep and dual use.

when American trade officials said: “Hey, you need to live up to your W.T.O. commitments to restrict state-funding of industries,” China basically said: “Why should we live by your interpretation of the rules? We are now big enough to make our own interpretations. We’re too big; you’re too late.”

Combined with China’s failure to come clean on what it knew about the origins of Covid-19, its crackdown on democratic freedoms in Hong Kong and on the Uyghur Muslim minority in Xinjiang, its aggressive moves to lay claim to the South China Sea, its increasing saber rattling toward Taiwan, its cozying up to Vladimir Putin (despite his savaging of Ukraine), Xi’s moves toward making himself president for life, his kneecapping of China’s own tech entrepreneurs, his tighter restrictions on speech and the occasional abduction of a leading Chinese businessman — all of these added up to one very big thing: Whatever trust that China had built up with the West since the late 1970s evaporated at the exact moment in history when trust, and shared values, became more important than ever in a world of deep, dual-use products driven by software, connectivity and microchips.

it started to matter a lot more to Western nations generally and the United States in particular that this rising power — which we were now selling to or buying from all sorts of dual-use digital devices or apps — was authoritarian.

eijing, for its part, argues that as China became a stronger global competitor to America — in deep goods like Huawei 5G — the United States simply could not handle it and decided to use its control over advanced semiconductor manufacturing and other high-tech exports from America, as well as from our allies, to ensure China always remained in our rearview mirror

Beijing came up with a new strategy, called “dual circulation.” It said: We will use state-led investments to make everything we possibly can at home, to become independent of the world. And we will use our manufacturing prowess to make the world dependent on our exports.

Chinese officials also argue that a lot of American politicians — led by Trump but echoed by many in Congress — suddenly seemed to find it very convenient to put the blame for economic troubles in the U.S.’s middle class not on any educational deficiencies, or a poor work ethic, or automation or the 2008 looting by financial elites, and the crisis that followed, but on China’s exports to the United States.

As Beijing sees it, China not only became America’s go-to boogeyman, but in their frenzy to blame Beijing for everything, members of Congress started to more recklessly promote Taiwan’s independence.

Xi told President Biden at their summit in Bali in November, in essence: I will not be the president of China who loses Taiwan. If you force my hand, there will be war. You don’t understand how important this is to the Chinese people. You’re playing with fire.

at some level Chinese officials now understand that, as a result of their own aggressive actions in recent years on all the fronts I’ve listed, they have frightened both the world and their own innovators at precisely the wrong time.

I don’t buy the argument that we are destined for war. I believe that we are doomed to compete with each other, doomed to cooperate with each other and doomed to find some way to balance the two. Otherwise we are both going to have a very bad 21st century.

I have to say, though, Americans and Chinese remind me of Israelis and Palestinians in one respect: They are both expert at aggravating the other’s deepest insecurities.

China’s Communist Party is now convinced that America wants to bring it down, which some U.S. politicians are actually no longer shy about suggesting. So, Beijing is ready to crawl into bed with Putin, a war criminal, if that is what it takes to keep the Americans at bay.

Americans are now worried that Communist China, which got rich by taking advantage of a global market shaped by American rules, will use its newfound market power to unilaterally change those rules entirely to its advantage. So we’ve decided to focus our waning strength vis-à-vis Beijing on ensuring the Chinese will always be a decade behind us on microchips.

I don’t know what is sufficient to reverse these trends, but I think I know what is necessary.

If it is not the goal of U.S. foreign policy to topple the Communist regime in China, the United States needs to make that crystal clear, because I found a lot more people than ever before in Beijing think otherwise.

As for China, it can tell itself all it wants that it has not taken a U-turn in recent years. But no one is buying it. China will never realize its full potential — in a hyper-connected, digitized, deep, dual-use, semiconductor-powered world — unless it understands that establishing and maintaining trust is now the single most important competitive advantage any country or company can have. And Beijing is failing in that endeavor.

In his splendid biography of the great American statesman George Shultz, Philip Taubman quotes one of Shultz’s cardinal rules of diplomacy and life: “Trust is the coin of the realm.”

History, however, may have other plans. Contrary to the mantra, it has no right or wrong side.

Judging, it turns out, isn’t history’s strong suit. Notions of justice change radically over time, and they are not the reason we collect, preserve or display objects from the past

To curators and historians, the evolving meaning of our objects is far more fascinating than whom they label as unrighteous

The collections of the Smithsonian contain, for instance, pikes from John Brown’s failed slave rebellion in the South in 1859. At different moments since then, his pikes have symbolized a demented terrorist’s scheme for mass murder, a religious fanatic’s fiery crusade and a hero’s lonely struggle for justice.

Nothing in our past, no matter how blatant it may seem to us today, is guaranteed eternal condemnation

Our recent reckoning with American history has shown the indelible impact of staid forms of institutional power, like dedicating monuments, inscribing plaques and holding hearings. Enshrining rioters as heroes could be done fairly quietly.

There’s no controlling what the future will say about us. Generations just keep coming, re-evaluating old heroes and asking new questions.

We cannot know; we have no ownership over what is to come. The best we can do is map our moment scrupulously, to preserve the signposts that will lead to a place we’ll never see.

As curators, as historians, as citizens, we are frequently reminded that the past is a foreign country. But so is the future.

“The evolution of cooperation required out-group hatred. Which is really sad,” said Nicholas Christakis, a Yale sociologist and author of “Blueprint: The Evolutionary Origins of a Good Society.”

No researcher argues that human nature is the sole, or even the primary, cause of today’s polarization. But savvy political operatives can exploit, leverage and encourage it. And those operatives are learning from their triumphs in divide-and-conquer politics.

“We wouldn’t have civilizations if we didn’t create groups. We are designed to form groups, and the only way to define a group is there has to be someone who’s not in it,” Mason said.

Experiments have revealed that “children as young as two will prefer other children randomly assigned to the same T-shirt color,”

enmity and derision can arise independently of any rational reason for it.

Mason and Christakis point to a famous-among-academics experiment from 1954. Social psychologist Muzafer Sherif took 22 Boy Scouts and separated them into two groups camping at Robbers Cave State Park in Oklahoma. Only after a week did they learn that there was another group at the far end of the campground.

What they did next fascinated the research team. Each group developed irrational contempt for the other. The boys in the other group were seen not just as rivals, but as fundamentally flawed human beings. Only when the two groups were asked to work together to solve a common problem did they warm up to one another.

And because many more districts are now deeply red or blue, rather than a mix of constituencies, House members have fewer reasons to adopt moderate positions.

“Homo sapiens is a social species; group affiliation is essential to our sense of self. Individuals instinctively think of themselves as representing broad socioeconomic and cultural categories rather than as distinctive packages of traits,”

Here’s where psychology gives way to political science. The American political system may cultivate “out-group” hatred, as academics put it. One of the scarce resources in this country is political power at the highest levels of government. The country has no parliamentary system in which multiple parties form governing coalitions.

Add to this fact the redistricting that ensures there are fewer truly competitive congressional races. The two parties have inexorably moved further apart ideologically, and leaders are more likely to be punished — “primaried” — if they reach across the aisle.

Shanto Iyengar, a Stanford political psychologist who coined the term “affective polarization,” explained in a 2018 paper why people typically identify with a group.

Human nature hasn’t changed, but technology has. The fragmentation of the media has made it easier to gather information in an echo chamber, Iyengar said. He calls this “sorting.” Not only do people cluster around specific beliefs or ideas, they physically cluster, moving to neighborhoods where residents are likely to look like them and think like them.

Partisan clustering has increased even within households. In 1965, Iyengar said, only about 60 percent of married couples had the same party registration. Today, the figure is greater than 85 percent

Asked in the summer of 2022 if they agree or disagree that members of the other party “lack the traits to be considered fully human — they behave like animals,” about 30 percent in both parties agreed, Mason’s research shows.

Research shows that affective polarization is intensifying across the political spectrum. Recent survey data revealed that more than half of Republicans and Democrats view the other party as “a threat,” and nearly as many agree with the description of the other party as “evil,” Mason said.

A recent paper published in the journal Science argued that the three core ingredients of political sectarianism are “othering, aversion, and moralization.” Trump has mastered that recipe. He activates emotional responses in his followers by telling them that they are threatened.

As for our continuing distress, the standard explanation is a uniquely American loneliness. The surgeon general, Vivek Murthy, declared it an epidemic in its own right.

The truth, however, is there’s no good evidence that Americans are lonelier than ever

a major recent poll shows that older Americans are now significantly less lonely than they were three years ago; a recent peer-reviewed study reports that middle-aged Americans describe themselves as less lonely than they were 20 years ag

Loneliness is more pervasive among younger Americans, but there too, the rates have also plummeted since 2020

Logically, we should be feeling better. Why can’t we shake this thing?

loneliness was never the core problem. It was, rather, the sense among so many different people that they’d been left to navigate the crisis on their own. How do you balance all the competing demands of health, money, sanity?

The answer was always the same: Figure it out.

while other countries built trust and solidarity, America — both during and after 2020 — left millions to fend for themselves.

For millions of Americans, distrust feels like the most rational state.

The very different people I spoke with that year all had one thing in common: a feeling that in the wake of Covid, all the larger institutions they had been taught to trust had failed them. At the most precarious times in their lives, they found there was no system in place to help.

four years later, the situation is, if anything, worse.

Nursing homes across the country, where poor labor conditions were linked to higher Covid mortality levels, remain understaffed, leaving old, frail residents more vulnerable than they should be. Hunger and food insecurity remain wrenching emergencies.

Students haven’t fully returned to school. Congress passed the Child Poverty Reduction Act of 2021, one of the most effective antipoverty measures in decades. Then a year later, Congress ended it, pushing some five million young people back down into extreme financial need.

When everything was uncertain and everyone’s future was on the line, we walked right up to the precipice of a moral breakthrough, and then we turned back.

Look at the way we all accustomed ourselves to the term “essential worker,” an ostensible term of respect that instead condemned people to work in manifestly dangerous conditions. The adoption of that term made visible something we now cannot unsee: In the United States the people we rely on most to keep our world functioning are the people we treated as disposable.

we might call the bigger problem structural isolation: abandoned by employers, deprived of shared purpose, denied care. The combined effect sent a strong message that individual lives weren’t worth as much anymore.

People treated one another accordingly. We all remember the viral videos of people screaming at one another in supermarkets and on public transportation. Violent crime spiked. Even reckless driving surged — but it happened only in the United States.

The reasons for that American exceptionalism become only more urgent in an election year, when, as in a public health crisis, presidents can try to bring people together or try to turn them against one another.

I’ve spoken to in-house editors and publicists who are more inundated than ever, unable to give each of their titles the attention they deserve. Their submissions and workloads have increased even as marketing and editorial resources for individual titles have tapered off.

In the corporate world, output seems to be becoming more and more of a percentage game. You throw a bunch of products against the wall, see what sticks, and write off the ones (a vast majority) that don’t.

What a remarkable change it would be if corporations would allow their employees to do the best job they can with each book that the company has chosen to buy, rather than allowing them to flail

I had always thought that “discoverability” was a unique problem for books because so much browsing happens online rather than in carefully curated physical stores, but the world of streaming TV and movies has begun to catch up

What do corporate publishing and streaming have in common? They’re very often run by people who don’t engage with the products they put out.

For the first time since the first World Happiness Report was published in 2012, the United States fell out of the Top 20 and dropped to 23rd, pushed down by cratering attitudes of Americans under 30.

Americans have long been an unhappy bunch. They have never ranked in the Top 10 of the World Happiness Report, which is based on how respondents in different countries rate their own happiness.

cited the disruptions to life brought about by the coronavirus pandemic as a chief cause of mental health challenges among younger Americans.

The happiest young people are in Lithuania, while the unhappiest are in Afghanistan.

“I have never seen such an extreme change,” John Helliwell, an economist and a co-author of the report, said in an interview, referring to the drop in happiness among younger people. “This has all happened in the last 10 years, and it’s mainly in the English-language countries. There isn’t this drop in the world as a whole.”

Respondents were asked — among other prompts — to think of their life as a ladder and to rate it on a scale of one to 10, with 10 being the best possible life.

this was the first time that the consortium separated results by age, finding disparities in the views of younger and older Americans. Among the 143 countries surveyed, the United States ranked 10th for people 60 and older, but 62nd for people under 30.

Jade Song, a 27-year-old novelist, counted herself among those who had become increasingly unhappy in recent years.

“Many of the things that would have normally taken place for people, particularly high school young adults, did not take place,” he added. “And that is still occurring.”

“It’s mostly because as an adult you suddenly become aware of all the world news and you pay attention more to what you can control, and you realize that there is so little you can control,” Ms. Song, who was not part of the study, said in an interview. “Even if you’re going to protests or paying your rent and bills all on time, it’s so difficult, especially now, to break free from how you’re living your life when you realize how little impact your actions actually have on a broader level.”

There is a silver lining, though

In 2022, a Harvard University study showed that well-being among young adults in the United States had declined in the previous 20 years. Young people — those between the ages of 18 and 25 — reported the lowest levels of happiness compared with other age groups, as well as the poorest mental and physical health, sense of purpose, character, virtue, close social relationships and financial stability

Similar findings have emerged in Britain and Canada.

“One factor, which we’re all thinking about, is social media,” said Dr. Robert Waldinger, the director of the Harvard Study of Adult Development

“Because there’s been some research that shows that depending on how we use social media, it lowers well-being, it increases rates of depression and anxiety, particularly among young girls and women, teenage girls.”

In addition, Dr. Waldinger said, the negative feedback loop from news consumption has become a contributing factor.

“There’s also a lot of anxiety about the state of the world,” he said. “About climate change. About all of the polarization that we’re seeing.”

in some other countries, such as Croatia, Switzerland and Austria, the World Happiness Report shows that young people are becoming happier.

“Part of the problem is that we have this huge expectation of happiness in America,” said Eric Weiner, the author of “The Geography of Bliss,” and so we suffer partly from the unhappiness of not being happy and the expectation that we should be happy. And not every country in the world has that.”

“There’s an assumption that if you’re American, you’re wealthy and you’re high tech and you’re successful; you should be happy,” he said. “There’s a lot of data that shows that the greater your expectations, the less you’re happy.”

The expectations for young people like Ms. Song, the novelist, said have shifted.

“We have less to look forward to,” she said. “Because in the future, there’s going to be climate change that will affect the way we live. I think there’s less of a clear-cut trajectory for our life paths, because for so long, it was so easy just to know that you could go get married and have your 2.5 kids, and then pay for your house. But now that path is a lot more closed.”

“The literature is clear in practice — the effect that this had on socialization, pro-social behavior, if you will, and the ability for people to feel connected and have a community,”

“A, this angst is very local and, B, it’s very recent, which means, C, it’s not fundamental and going to last forever,” he said. “If it has been created that quickly, it could be removed that quickly.”

He is concerned that masters of the A.I. universes are developing systems that will expand chasms of inequality. He fears the transition to A.I. will be so abrupt that entire professional fields will be left doing menial jobs, or nothing, stripping people of dignity and unleashing floods of “despair.”

Father Benanti, who does not believe in the industry’s ability to self-regulate and thinks some rules of the road are required in a world where deep fakes and disinformation can erode democracy.

He shares his insights with Pope Francis, who in his annual World Day of Peace message on Jan. 1 called for a global treaty to ensure the ethical development and use of AI to prevent a world devoid of human mercy, where inscrutable algorithms decide who is granted asylum, who gets a mortgage, or who, on the battlefield, lives or dies.

all the time he applies his perspective about what it means to be alive, and to be human, when machines seem more alive and human. “This is a spiritual question,” he said.

raises enormous questions about redistributing wealth in an A.I. dominant universe.

he pursued an engineering degree at Sapienza University in Rome. It wasn’t enough.“I started to feel that something was missing,” he said, explaining that his advancement as an engineering student erased the mystique machines held for him. “I simply broke the magic.”

He left Rome to study in Assisi, the home of St. Francis, and over the next decade, took his final vows as a friar, was ordained as a priest and defended his dissertation on human enhancement and cyborgs. He got his job at the Gregorian, and eventually as the Vatican’s IT ethics guy.

In 2017, Cardinal Ravasi organized an event at the Italian embassy to the Holy See where Father Benanti gave a talk on the ethics of A.I. Microsoft officials in attendance were impressed and asked to stay in touch. That same year, the Italian government asked him to contribute to A.I. policy documents and the next year he successfully applied to sit on its commission for developing a national A.I. strategy.

Francis, he said, didn’t at first realize what Microsoft really did, but liked that Mr. Smith took out of his pocket one of the pope’s speeches on social media and showed the pontiff the concerns the business executive had highlighted and shared.

e said, arguing that as ancient Roman augurs turned to the flight of birds for direction, A.I., with its enormous grasp of our physical, emotional and preferential data, could be the new oracles, determining decisions, and replacing God with false idols.

“It’s something old that probably we think that we left behind,” the friar said, “but that is coming back.”

it is clear that its widespread adoption is a matter of when, not if. There is no debate that we are moving towards a world where “real life” and digital technology seamlessly blur

Over the years there have been multiple reports of people being harassed and even “raped” in the metaverse: an experience that feels scarily real because of how immersive virtual reality is. As the lines between real life and the digital world blur to a point that they are almost indistinguishable, will there be a meaningful difference between online assault and an attack in real life?

more broadly, spatial computing is going to alter what we consider reality

Researchers from Stanford and Michigan University recently undertook a study on the Vision Pro and other “passthrough” headsets (that’s the technical term for the feature which brings VR content into your real-world surrounding so you see what’s around you while using the device) and emerged with some stark warnings about how this tech might rewire our brains and “interfere with social connection”.

These headsets essentially give us all our private worlds and rewrite the idea of a shared reality. The cameras through which you see the world can edit your environment – you can walk to the shops wearing it, for example, and it might delete all the homeless people from your view and make the sky brighter.

“What we’re about to experience is, using these headsets in public, common ground disappears,”

“People will be in the same physical place, experiencing simultaneous, visually different versions of the world. We’re going to lose common ground.”

It’s not just the fact that our perception of reality might be altered that’s scary: it’s the fact that a small number of companies will have so much control over how we see the world. Think about how much influence big tech already has when it comes to content we see, and then multiply that a million times over. You think deepfakes are scary? Wait until they seem even more realistic.

We’re seeing a global rise of authoritarianism. If we’re not careful this sort of technology is going to massively accelerate it.

Being able to suck people into an alternate universe, numb them with entertainment, and dictate how they see reality? That’s an authoritarian’s dream. We’re entering an age where people can be mollified and manipulated like never before

there is a world of content out there that has not been watermarked, which is done by adding imperceptible information to a digital file so that its provenance can be traced. Once watermarking at creation becomes widespread, and people adapt to distrust content that is not watermarked, then everything produced before that point in time can be much more easily called into question.

countering them is much harder when the cost of creating near-perfect fakes has been radically reduced.

There are many examples of how economic and political powers manipulated the historical record to their own ends. Stalin purged disloyal comrades from history by executing them — and then altering photographic records to make it appear as if they never existed

Slovenia, upon becoming an independent country in 1992, “erased” over 18,000 people from the registry of residents — mainly members of the Roma minority and other ethnic non-Slovenes. In many cases, the government destroyed their physical records, leading to their loss of homes, pensions, and access to other services, according to a 2003 report by the Council of Europe Commissioner for Human Rights.

The infamous Protocols of the Elders of Zion, first published in a Russian newspaper in 1903, purported to be meeting minutes from a Jewish conspiracy to control the world. First discredited in August 1921, as a forgery plagiarized from multiple unrelated sources, the Protocols featured prominently in Nazi propaganda, and have long been used to justify antisemitic violence, including a citation in Article 32 of Hamas’s 1988 founding Covenant.

In 1924, the Zinoviev Letter, said to be a secret communiqué from the head of the Communist International in Moscow to the Communist Party of Great Britain to mobilize support for normalizing relations with the Soviet Union, was published by The Daily Mail four days before a general election. The resulting scandal may have cost Labour the election.

As it becomes easier to generate historical disinformation, and as the sheer volume of digital fakes explodes, the opportunity will become available to reshape history, or at least to call our current understanding of it into question.

Decades later Operation Infektion — a Soviet disinformation campaign — used forged documents to spread the idea that the United States had invented H.I.V., the virus that causes AIDS, as a biological weapon.

Fortunately, a path forward has been laid by the same companies that created the risk.

In indexing a large share of the world’s digital media to train their models, the A.I. companies have effectively created systems and databases that will soon contain all of humankind’s digitally recorded content, or at least a meaningful approximation of it.

They could start work today to record watermarked versions of these primary documents, which include newspaper archives and a wide range of other sources, so that subsequent forgeries are instantly detectable.

many of the intellectual property concerns around providing a searchable online archive do not apply to creating watermarked and time-stamped versions of documents, because those versions need not be made publicly available to serve their purpose. One can compare a claimed document to the recorded archive by using a mathematical transformation of the document known as a “hash,” the same technique the Global Internet Forum to Counter Terrorism, uses to help companies screen for known terrorist content.

creating verified records of historical documents can be valuable for the large A.I. companies. New research suggests that when A.I. models are trained on A.I.-generated data, their performance quickly degrades. Thus separating what is actually part of the historical record from newly created “facts” may be critical.

Preserving the past will also mean preserving the training data, the associated tools that operate on it and even the environment that the tools were run in.

Such a vellum will be a powerful tool. It can help companies to build better models, by enabling them to analyze what data to include to get the best content, and help regulators to audit bias and harmful content in the models

What turned the neurotic Presbyterian teenager into the great founder of the European Enlightenment?

your life might actually get better. Give up the prospect of life after death, and you will finally really appreciate life before it. Give up metaphysics, and you can concentrate on physics. Give up the idea of your precious, unique, irreplaceable self, and you might actually be more sympathetic to other people.

Go back to your backgammon game after your skeptical crisis, Hume wrote, and it will be exactly the same game.

Desideri retreated to an even more remote monastery. He worked on his Christian tracts and mastered the basic texts of Buddhism. He also translated the work of the great Buddhist philosopher Tsongkhapa into Italian.

That sure sounded like Buddhist philosophy to me—except, of course, that Hume couldn’t have known anything about Buddhist philosophy.

He spent the next five years in the Buddhist monasteries tucked away in the mountains around Lhasa. The monasteries were among the largest academic institutions in the world at the time. Desideri embarked on their 12-year-long curriculum in theology and philosophy. He composed a series of Christian tracts in Tibetan verse, which he presented to the king. They were beautifully written on the scrolls used by the great Tibetan libraries, with elegant lettering and carved wooden cases.

Desideri describes Tibetan Buddhism in great and accurate detail, especially in one volume titled “Of the False and Peculiar Religion Observed in Tibet.” He explains emptiness, karma, reincarnation, and meditation, and he talks about the Buddhist denial of the self.

The drive to convert and conquer the “false and peculiar” in the name of some metaphysical absolute was certainly there, in the West and in the East. It still is

For a long time, the conventional wisdom was that the Jesuits were retrograde enforcers of orthodoxy. But Feingold taught me that in the 17th century, the Jesuits were actually on the cutting edge of intellectual and scientific life. They were devoted to Catholic theology, of course, and the Catholic authorities strictly controlled which ideas were permitted and which were forbidden. But the Jesuit fathers at the Royal College knew a great deal about mathematics and science and contemporary philosophy—even heretical philosophy.

La Flèche was also startlingly global. In the 1700s, alumni and teachers from the Royal College could be found in Paraguay, Martinique, the Dominican Republic, and Canada, and they were ubiquitous in India and China. In fact, the sleepy little town in France was one of the very few places in Europe where there were scholars who knew about both contemporary philosophy and Asian religion.

Twelve Jesuit fathers had been at La Flèche when Desideri visited and were still there when Hume arrived. So Hume had lots of opportunities to learn about Desideri.One name stood out: P. Charles François Dolu, a missionary in the Indies. This had to be the Père Tolu I had been looking for; the “Tolu” in Petech’s book was a transcription error. Dolu not only had been particularly interested in Desideri; he was also there for all of Hume’s stay. And he had spent time in the East. Could he be the missing link?

in the 1730s not one but two Europeans had experienced Buddhism firsthand, and both of them had been at the Royal College. Desideri was the first, and the second was Dolu. He had been part of another fascinating voyage to the East: the French embassy to Buddhist Siam.

Dolu was an evangelical Catholic, and Hume was a skeptical Protestant, but they had a lot in common—endless curiosity, a love of science and conversation, and, most of all, a sense of humor. Dolu was intelligent, knowledgeable, gregarious, and witty, and certainly “of some parts and learning.” He was just the sort of man Hume would have liked.

Of course, it’s impossible to know for sure what Hume learned at the Royal College, or whether any of it influenced the Treatise. Philosophers like Descartes, Malebranche, and Bayle had already put Hume on the skeptical path. But simply hearing about the Buddhist argument against the self could have nudged him further in that direction. Buddhist ideas might have percolated in his mind and influenced his thoughts, even if he didn’t track their source

my quirky personal project reflected a much broader trend. Historians have begun to think about the Enlightenment in a newly global way. Those creaky wooden ships carried ideas across the boundaries of continents, languages, and religions just as the Internet does now (although they were a lot slower and perhaps even more perilous). As part of this new global intellectual history, new bibliographies and biographies and translations of Desideri have started to appear, and new links between Eastern and Western philosophy keep emerging.

It’s easy to think of the Enlightenment as the exclusive invention of a few iconoclastic European philosophers. But in a broader sense, the spirit of the Enlightenment, the spirit that both Hume and the Buddha articulated, pervades the story I’ve been telling.

as I read Buddhist philosophy, I began to notice something that others had noticed before me. Some of the ideas in Buddhist philosophy sounded a lot like what I had read in Hume’s Treatise. But this was crazy. Surely in the 1730s, few people in Europe knew about Buddhist philosophy

But the characters in this story were even more strongly driven by the simple desire to know, and the simple thirst for experience. They wanted to know what had happened before and what would happen next, what was on the other shore of the ocean, the other side of the mountain, the other face of the religious or philosophical—or even sexual—divide.

Like Dolu and Desideri, the gender-bending abbé and the Siamese astronomer-king, and, most of all, like Hume himself, I had found my salvation in the sheer endless curiosity of the human mind—and the sheer endless variety of human experience.

A glimmer of hope for Biden emerged toward the end of the survey: “If Donald Trump is found guilty and convicted this year of a felony — with Donald Trump as the Republican candidate and Joe Biden as the Democratic candidate — for whom would you vote?”In this hypothetical circumstance, Biden pulls ahead of Trump, 45-43.

when asked, “How willing would you be to vote for Donald Trump if he is convicted of a crime?” 53 percent of registered voters surveyed said they would be “unwilling” to do so; 46 percent said “very unwilling”; and 7 percent said “somewhat unwilling.”

Bloomberg-Morning Consult asked respondents whether they would be unwilling to vote for Trump if he were “sentenced to prison”: 55 percent said unwilling, 48 percent very unwilling and 7 percent said somewhat unwilling.

YouGov found that 45 percent of respondents were either unaware of or uncertain that Trump had “been charged with falsifying business records to conceal hush money payments to Stormy Daniels, a porn star” and that Trump “had been found liable for sexually assaulting and defaming writer E. Jean Carroll.”

The most recent NBC News poll, conducted at the end of January, has Trump favored over Biden by a substantial 47 percent to 42 percent.

In the RealClearPolitics compilation of polls that add Robert Kennedy Jr., Cornel West and Jill Stein to the mix, Trump’s lead over Biden more than doubles, to 4.8 points, 41.6 to 36.8 percent. Kennedy gets 13 percent, and West and Stein each get 2.1 percent.

Along with the threat posed by third-party candidates, two major crises — immigration and the Israeli assault on Hamas in Gaza — have become significant liabilities for the Biden campaign.

The Dec. 10-14 New York Times/Siena poll found that young voters, aged 18 to 29, favored Trump over Biden 49-43. These voters said they trusted Trump over Biden “to do a better job on the Israeli-Palestinian conflict” 49-30. In the 2020 election, Biden beat Trump among 18-to-29-year-old voters by 24 points, 60-36, according to exit polls, by far his biggest margin in all age groups.

“To win in 2024, Biden will need to convince voters that he is still the proud moderate they voted for in 2020,” Cowan wrote by email. “He has a lot of evidence on his side, but he still has a lot of convincing to do.”

Biden’s showing “middle- and working-class voters that he understands their values and takes seriously their concerns around crime, immigration and the economy — which, as polling makes clear, are often dramatically different and far more mainstream and centrist than those of college-educated elites who staff much of Washington — is the only way to win.”

While bitterly criticized by many liberals, the Supreme Court decision last year to ban affirmative action in public and private colleges will in fact reduce the salience of an issue that has historically worked to build support for Republicans.

Brown University professor Claire Wardle said the Observatory had created innovative methodology and trained the next generation of experts.

“Closing down a lab like this would always be a huge loss, but doing so now, during a year of global elections, makes absolutely no sense,” said Wardle, who previously led research at anti-misinformation nonprofit First Draft. “We need universities to use their resources and standing in the community to stand up to criticism and headlines.”

The study of misinformation has become increasingly controversial, and Stamos, DiResta and Starbird have been besieged by lawsuits, document requests and threats of physical harm. Leading the charge has been Rep. Jim Jordan (R-Ohio), whose House subcommittee alleges the Observatory improperly worked with federal officials and social media companies to violate the free-speech rights of conservatives.

In a joint statement, Stamos and DiResta said their work involved much more than elections, and that they had been unfairly maligned.

“The politically motivated attacks against our research on elections and vaccines have no merit, and the attempts by partisan House committee chairs to suppress First Amendment-protected research are a quintessential example of the weaponization of government,” they said.

Stamos founded the Observatory after publicizing that Russia has attempted to influence the 2016 election by sowing division on Facebook, causing a clash with the company’s top executives. Special counsel Robert S. Mueller III later cited the Facebook operation in indicting a Kremlin contractor. At Stanford, Stamos and his team deepened his study of influence operations from around the world, including one it traced to the Pentagon.

Stamos told associates he stepped back from leading the Observatory last year in part because the political pressure had taken a toll. Stamos had raised most of the money for the project, and the remaining faculty have not been able to replicate his success, as many philanthropic groups shift their focus on artificial intelligence and other, fresher topics.

In supporting the project further, the university would have risked alienating conservative donors, Silicon Valley figures, and members of Congress, who have threatened to stop all federal funding for disinformation research or cut back general support.

The Observatory’s non-election work has included developing curriculum for teaching college students about how to handle trust and safety issues on social media platforms and launching the first peer-reviewed journal dedicated to that field. It has also investigated rings publishing child sexual exploitation material online and flaws in the U.S. system for reporting it, helping to prepare platforms to handle an influx of computer-generated material.

One man, speaking about one of his favorite young influencers in a Telegram exchange captured by a child-safety activist, said that her mother knew “damn well” that many of her daughter’s followers were “pervy adult men.”

Meta looms over everything young influencers do on Instagram. It connects their accounts with strangers, and it can upend their star turns when it chooses. The company periodically shuts down accounts if it determines they have violated policies against child sexual exploitation or abuse. Some parents say their accounts have been shut down without such violations. 

Over the course of reporting this story, during which time the Journal inquired about the account the mom managed for her daughter, Meta shut down the account twice. The mom said she believed she hadn’t violated Meta’s policies. 

Meta’s guidance for content creators stresses the importance of engaging with followers to keep them and attract new ones. The hundreds of comments on any given post included some from other young fashion influencers, but also a large number of men leaving comments like “Gorgeous!” The mom generally liked or thanked them all, save for any that were expressly inappropriate. 

Meta spokesman Andy Stone said the company enables parents who run accounts for their children to control who is able to message them on Instagram or comment on their accounts. Meta’s guidance for creators also offers tips for building a safe online community, and the company has publicized a range of tools to help teens and parents achieve this.

Like many young girls, the daughter envied fashion influencers who made a living posting glamour content. When the mother agreed to help her daughter build her following and become an influencer, she set some rules. Her daughter wouldn’t be allowed to access the account or interact with anyone who sent messages. And they couldn’t post anything indicating exactly where they live. 

The mom stopped blocking so many users. Within a year of launching, the account had more than 100,000 followers. The daughter’s popularity earned her invitations to modeling events in big coastal cities where she met other young influencers. 

Social-media platforms have helped level the playing field for parents seeking an audience for their children’s talents. Instagram, in particular, is visually driven and easily navigable, which also makes it appealing for child-focused brands.

While Meta bans children under the age of 13 from independently opening social-media accounts, the company allows what it calls adult-run minor accounts, managed by parents. Often those accounts are pursuing influencer status, part of a burgeoning global influencer industry expected to be worth $480 billion by 2027, according to a recent Goldman Sachs report. 

Young influencers, reachable through direct messages, routinely solicit their followers for patronage, posting links to payment accounts and Amazon gift registries in their bios.

The Midwestern mom debated whether to charge for access to extra photos and videos via Instagram’s subscription feature. She said she has always rejected private offers to buy photos of her daughter, but she decided that offering subscriptions was different because it didn’t involve a one-on-one transaction.

The Journal asked Meta why it had at some points removed photos from the account. Weeks later, Meta disabled the account’s subscription feature, and then shut down the account without saying why. 

“There’s no personal connection,” she said. “You’re just finding a way to monetize from this fame that’s impersonal.”

The mom allowed the men to purchase subscriptions so long as they kept their distance and weren’t overtly inappropriate in messages and comments. “In hindsight, they’re probably the scariest ones of all,” she said. 

Stone, the Meta spokesman, said that the company will no longer allow accounts that primarily post child-focused content to offer subscriptions or receive gifts, and that the company is developing tools to enforce that.

he mom saw her daughter, though young, as capable of choosing to make money as an influencer and deciding when she felt uncomfortable. The mom saw her own role as providing the support needed for her daughter to do that.

The mom also discussed safety concerns with her now ex-husband, who has generally supported the influencer pursuit. In an interview, he characterized the untoward interest in his daughter as “the seedy underbelly” of the industry, and said he felt comfortable with her online presence so long as her mom posted appropriate content and remained vigilant about protecting her physical safety.

an anonymous person professing to be a child-safety activist sent her an email that contained screenshots and videos showing her daughter’s photos being traded on Telegram. Some of the users were painfully explicit about their sexual interest. Many of the photos were bikini or leotard photos from when the account first started.

Still, the mom realized she couldn’t stop men from trading the photos, which will likely continue to circulate even after her daughter becomes an adult. “Every little influencer with a thousand or more followers is on Telegram,” she said. “They just don’t know it.”

Early last year, Meta safety staffers began investigating the risks associated with adult-run accounts for children offering subscriptions, according to internal documents. The staffers reviewed a sample of subscribers to such accounts and determined that nearly all the subscribers demonstrated malicious behavior toward children.

The staffers found that the subscribers mostly liked or saved photos of children, child-sexualizing material and, in some cases, illicit underage-sex content. The users searched the platform using hashtags such as #sexualizegirls and #tweenmodel. 

The staffers found that some accounts with large numbers of followers sold additional content to subscribers who offered extra money on Instagram or other platforms, and that some engaged with subscribers in sexual discussions about their children. In every case, they concluded that the parents running those accounts knew that their subscribers were motivated by sexual gratification.

In the following months, the Journal began its own review of parent-run modeling accounts and found numerous instances where Meta wasn’t enforcing its own child-safety policies and community guidelines. 

The Journal asked Meta about several accounts that appeared to have violated platform rules in how they promoted photos of their children. The company deleted some of those accounts, as well as others, as it worked to address safety issues.

In 2022, Instagram started letting certain content creators offer paid-subscription services. At the time, the company allowed accounts featuring children to offer subscriptions if they were run or co-managed by parents.

The removal of the account made for a despondent week for the mom and daughter. The mother was incensed at Meta’s lack of explanation and the prospect that users had falsely reported inappropriate activity on the account. She was torn about what to do. When it was shut down, the account had roughly 80% male followers.

The account soon had more than 100,000 followers, about 92% of whom were male, according to the dashboard. Within months, Meta shut down that account as well. The company said the account had violated its policies related to child exploitation, but it didn’t specify how. 

Meta’s Stone said it doesn’t allow accounts it has previously shut down to resume the same activity on backup accounts. 

“People used to talk about politicians trying to control our bodies,” she said. “Now it’s, they have no business getting involved in these medical decisions, these politicians don’t have medical expertise, they’re making these laws, and they’re not basing it on health care or science.”

Seventy-three percent of independents who support abortion rights said stories about women almost dying because of bans would affect how they vote.

“Now it’s about pregnancy, and everybody knows someone who had a baby or wants to have a baby or might get pregnant,” she said. “It’s profoundly personal to a majority of the public.”

Anti-abortion groups have responded by trying to carve out a difference between “elective abortion” for unwanted pregnancies — which they want banned — and “maternal fetal separation” in medical emergencies. (The medical procedure is the same.)

Opponents have long stigmatized abortion as something irresponsible women use as birth control or because they care more about their careers than having children. “When the focus shifts to the dangers that abortion bans inflict on pregnant people,” said Reva Siegel, a constitutional law professor at Yale who has written extensively about the country’s abortion conflict, “it’s easier for Americans to talk about.”

Technology and criminal law have flipped the script, she said.

Before Roe legalized abortion nationally in 1973, the law allowed more leeway for what were considered “therapeutic abortions.” Doctors, often solo practitioners, could use their good faith judgment to provide them. Even the Southern Baptist Convention supported abortions in cases of fetal deformity or when a woman’s physical or mental health was at risk.

Now, the threat of prosecution, $100,000 fines and loss of their medical licenses have chilled doctors and hospital systems in treating women with pregnancy complications. More often than not in some states, lawyers are making the decisions.

In Georgia, she said, more people opposed the state’s ban on abortion after six weeks of pregnancy once they were told that this meant two weeks after the average woman misses her period — not, as her own partner believed, six weeks after conception. Some voters, she said, believed that six weeks meant six weeks after women found out they were pregnant.

In fact, the news from Wall Street lately has mostly been about retreat from climate goals, rather than recommitment. Banks and asset managers are withdrawing from international climate alliances and chafing at their rules. Regional banks are stepping up lending to fossil fuel producers. Sustainable investment funds have sustained crippling outflows, and many have collapsed.

In some cases, it’s a classic prisoner’s dilemma: If firms collectively shift to cleaner energy, a cooler climate benefits everyone more in the future

in the short term, each firm has an individual incentive to cash in on fossil fuels, making the transition much harder to achieve.

when it comes to avoiding climate damage to their own operations, the financial industry is genuinely struggling to comprehend what a warming future will mean.

A global compact of financial institutions made commitments worth $130 trillion to try to bring down emissions, confident that governments would create a regulatory and financial infrastructure to make those investments profitable. And in 2022, the Inflation Reduction Act passed.

What about the risk that climate change poses to the financial industry’s own investments, through more powerful hurricanes, heat waves that knock out power grids, wildfires that wipe out towns?

“If we think about what is going to be the best way to tilt your portfolios in the direction to benefit, it’s really difficult to do,”

“These will probably be great investments over 20 years, but when we’re judged over one to three years, it’s a little more challenging for us.”

Some firms cater to institutional clients, like public employee pension funds, that want combating climate change to be part of their investment strategy and are willing to take a short-term hit. But they aren’t a majority

And over the past couple of years, many banks and asset managers have shrunk from anything with a climate label for fear of losing business from states that frown on such concerns.

On top of that, the war in Ukraine scrambled the financial case for backing a rapid energy transition. Artificial intelligence and the movement toward greater electrification are adding demand for power, and renewables haven’t kept up

All of that is about the relative appeal of investments that would slow climate change

If you bought some of the largest solar-energy exchange-traded funds in early 2023, you would have lost about 20 percent of your money, while the rest of the stock market soared.

There is evidence that banks and investors price in some physical risk, but also that much of it still lurks, unheeded.

“I’m very, very worried about this, because insurance markets are this opaque weak link,” Dr. Sastry said. “There are parallels to some of the complex linkages that happened in 2008, where there is a weak and unregulated market that spills over to the banking system.”

Regulators worry that failing to understand those ripple effects could not just put a single bank in trouble but even become a contagion that would undermine the financial system.

But while the European Central Bank has made climate risk a consideration in its policy and oversight, the Federal Reserve has resisted taking a more active role, despite indications that extreme weather is feeding inflation and that high interest rates are slowing the transition to clean energy.

“The argument has been, ‘Unless we can convincingly show it’s part of our mandate, Congress should deal with it, it’s none of our business,’”

a much nearer-term uncertainty looms: the outcome of the U.S. election, which could determine whether further action is taken to address climate concerns or existing efforts are rolled back. An aggressive climate strategy might not fare as well during a second Trump administration, so it may seem wise to wait and see how it shakes out.

big companies are hesitating on climate-sensitive investments as November approaches, but says that “two things are misguided and quite dangerous about that hypothesis.”

One: States like California are establishing stricter rules for carbon-related financial disclosures and may step it up further if Republicans win

And two: Europe is phasing in a “carbon border adjustment mechanism,” which will punish polluting companies that want to do business there.

at the moment, even European financial institutions feel pressure from the United States, which — while providing some of the most generous subsidies so far for renewable-energy investment — has not imposed a price on carbon.

The global insurance company Allianz has set out a plan to align its investments in a way that would prevent warming above 1.5 degrees Celsius by the end of the century, if everyone else did the same. But it’s difficult to steer a portfolio to climate-friendly assets while other funds take on polluting companies and reap short-term profits for impatient clients.

“This is the main challenge for an asset manager, to really bring the customer along,” said Markus Zimmer, an Allianz economist. Asset managers don’t have sufficient tools on their own to move money out of polluting investments and into clean ones, if they want to stay in business,

“Of course it helps if the financial industry is somehow ambitious, but you cannot really substitute the lack of actions by policymakers,”

According to new research, the benefit is greater when decarbonization occurs faster, because the risks of extreme damage mount as time goes on. But without a uniform set of rules, someone is bound to scoop up the immediate profits, disadvantaging those that don’t — and the longer-term outcome is adverse for all.

Why write this book? The Singularity Is Near talked about the future, but 20 years ago, when people didn’t know what AI was. It was clear to me what would happen, but it wasn’t clear to everybody. Now AI is dominating the conversation. It is time to take a look again both at the progress we’ve made – large language models (LLMs) are quite delightful to use – and the coming breakthroughs.

It is hard to imagine what this would be like, but it doesn’t sound very appealing… Think of it like having your phone, but in your brain. If you ask a question your brain will be able to go out to the cloud for an answer similar to the way you do on your phone now – only it will be instant, there won’t be any input or output issues, and you won’t realise it has been done (the answer will just appear). People do say “I don’t want that”: they thought they didn’t want phones either!

The most important driver is the exponential growth in the amount of computing power for the price in constant dollars. We are doubling price-performance every 15 months. LLMs just began to work two years ago because of the increase in computation.

What’s missing currently to bring AI to where you are predicting it will be in 2029? One is more computing power – and that’s coming. That will enable improvements in contextual memory, common sense reasoning and social interaction, which are all areas where deficiencies remain

LLM hallucinations [where they create nonsensical or inaccurate outputs] will become much less of a problem, certainly by 2029 – they already happen much less than they did two years ago. The issue occurs because they don’t have the answer, and they don’t know that. They look for the best thing, which might be wrong or not appropriate. As AI gets smarter, it will be able to understand its own knowledge more precisely and accurately report to humans when it doesn’t know.

What exactly is the Singularity? Today, we have one brain size which we can’t go beyond to get smarter. But the cloud is getting smarter and it is growing really without bounds. The Singularity, which is a metaphor borrowed from physics, will occur when we merge our brain with the cloud. We’re going to be a combination of our natural intelligence and our cybernetic intelligence and it’s all going to be rolled into one. Making it possible will be brain-computer interfaces which ultimately will be nanobots – robots the size of molecules – that will go noninvasively into our brains through the capillaries. We are going to expand intelligence a millionfold by 2045 and it is going to deepen our awareness and consciousness.

Why should we believe your dates? I’m really the only person that predicted the tremendous AI interest that we’re seeing today. In 1999 people thought that would take a century or more. I said 30 years and look what we have.

I have a chapter on perils. I’ve been involved with trying to find the best way to move forward and I helped to develop the Asilomar AI Principles [a 2017 non-legally binding set of guidelines for responsible AI development]

All the major companies are putting more effort into making sure their systems are safe and align with human values than they are into creating new advances, which is positive.

Not everyone is likely to be able to afford the technology of the future you envisage. Does technological inequality worry you? Being wealthy allows you to afford these technologies at an early point, but also one where they don’t work very well. When [mobile] phones were new they were very expensive and also did a terrible job. They had access to very little information and didn’t talk to the cloud. Now they are very affordable and extremely useful. About three quarters of people in the world have one. So it’s going to be the same thing here: this issue goes away over time.

The book looks in detail at AI’s job-killing potential. Should we be worried? Yes, and no. Certain types of jobs will be automated and people will be affected. But new capabilities also create new jobs. A job like “social media influencer” didn’t make sense, even 10 years ago. Today we have more jobs than we’ve ever had and US average personal income per hours worked is 10 times what it was 100 years ago adjusted to today’s dollars. Universal basic income will start in the 2030s, which will help cushion the harms of job disruptions. It won’t be adequate at that point but over time it will become so.

Everything is progressing exponentially: not only computing power but our understanding of biology and our ability to engineer at far smaller scales. In the early 2030s we can expect to reach longevity escape velocity where every year of life we lose through ageing we get back from scientific progress. And as we move past that we’ll actually get back more years.

What is your own plan for immortality? My first plan is to stay alive, therefore reaching longevity escape velocity. I take about 80 pills a day to help keep me healthy. Cryogenic freezing is the fallback. I’m also intending to create a replicant of myself [an afterlife AI avatar], which is an option I think we’ll all have in the late 2020s

I did something like that with my father, collecting everything that he had written in his life, and it was a little bit like talking to him. [My replicant] will be able to draw on more material and so represent my personality more faithfully.

What should we be doing now to best prepare for the future? It is not going to be us versus AI: AI is going inside ourselves. It will allow us to create new things that weren’t feasible before. It’ll be a pretty fantastic future.

“Over 80 technical papers published since January 2022,” LeCun responded. “What about you?”

To which Musk posted: “That’s nothing, you’re going soft. Try harder!

At stake are the hearts and minds of AI experts—academic and otherwise—needed to usher in the technology

“Join xAI,” LeCun wrote, “if you can stand a boss who:– claims that what you are working on will be solved next year (no pressure).– claims that what you are working on will kill everyone and must be stopped or paused (yay, vacation for 6 months!).– claims to want a ‘maximally rigorous pursuit of the truth’ but spews crazy-ass conspiracy theories on his own social platform.”

Some read Musk’s “science” dig as dismissing the role research has played for a generation of AI experts. For years, the Metas and Googles of the world have hired the top minds in AI from universities, indulging their desires to keep a foot in both worlds by allowing them to release their research publicly, while also trying to deploy products. 

For an academic such as LeCun, published research, whether peer-reviewed or not, allowed ideas to flourish and reputations to be built, which in turn helped build stars in the system.

LeCun has been at Meta since 2013 while serving as an NYU professor since 2003. His tweets suggest he subscribes to the philosophy that one’s work needs to be published—put through the rigors of being shown to be correct and reproducible—to really be considered science. 

“If you do research and don’t publish, it’s not Science,” he posted in a lengthy tweet Tuesday rebutting Musk. “If you never published your research but somehow developed it into a product, you might die rich,” he concluded. “But you’ll still be a bit bitter and largely forgotten.” 

After pushback, he later clarified in another post: “What I *AM* saying is that science progresses through the collision of ideas, verification, analysis, reproduction, and improvements. If you don’t publish your research *in some way* your research will likely have no impact.”

The spat inspired debate throughout the scientific community. “What is science?” Nature, a scientific journal, asked in a headline about the dust-up.

Others, such as Palmer Luckey, a former Facebook executive and founder of Anduril Industries, a defense startup, took issue with LeCun’s definition of science. “The extreme arrogance and elitism is what people have a problem with,” he tweeted.

For Musk, who prides himself on his physics-based viewpoint and likes to tout how he once aspired to work at a particle accelerator in pursuit of the universe’s big questions, LeCun’s definition of science might sound too ivory-tower. 

Musk has blamed universities for helping promote what he sees as overly liberal thinking and other symptoms of what he calls the Woke Mind Virus. 

Over the years, an appeal of working for Musk has been the impression that his companies move quickly, filled with engineers attracted to tackling hard problems and seeing their ideas put into practice.

“I’ve teamed up with Elon to see if we can actually apply these new technologies to really make a dent in our understanding of the universe,” Igor Babuschkin, an AI expert who worked at OpenAI and Google’s DeepMind, said last year as part of announcing xAI’s mission. 

The creation of xAI quickly sent ripples through the AI labor market, with one rival complaining it was hard to compete for potential candidates attracted to Musk and his reputation for creating value

that was before xAI’s latest round raised billions of dollars, putting its valuation at $24 billion, kicking off a new recruiting drive. 

It was already a seller’s market for AI talent, with estimates that there might be only a couple hundred people out there qualified to deal with certain pressing challenges in the industry and that top candidates can easily earn compensation packages worth $1 million or more

Since the launch, Musk has been quick to criticize competitors for what he perceived as liberal biases in rival AI chatbots. His pitch of xAI being the anti-woke bastion seems to have worked to attract some like-minded engineers.

As for Musk’s final response to LeCun’s defense of research, he posted a meme featuring Pepé Le Pew that read: “my honest reaction.”
