The oldest of the books of the Hebrew Bible date to roughly 3,000 years ago; the pyramids of Egypt go back about 5,000 years. These were not prehumans or near relatives. They were like us: complex, organized, alive to meaning and living at a time beyond reckoning.

Ruth Tringham of the University of California, Berkeley, who has devoted years to humanizing the remnants of this city of the dim past by focusing on one skeleton, of a woman she has dubbed Dido. Dido replastered her walls regularly, kept her home swept clean, covered the floor in reed mats and decorated the place with art: clay figures of animals and stylized human females. In other words: much like us.

Catalhoyuk was founded by pioneers of urban living. “When the earliest construction began,” Newitz writes, “many people coming to live at Catalhoyuk were only a generation or two removed from nomadism.” It was brand-new, this fixed settlement thing, but it proved remarkably successful. By the time Dido was born, the city was about 600 years old

A thousand years ago, meanwhile, East St. Louis, Ill., was the site of an urban sanctuary that archaeologists today call Cahokia. With a population of 30,000, it was larger than Paris was at the time. Like Paris, with its Eiffel Tower and Notre-Dame, it had distinguishing physical landmarks in the form of black earthen pyramids. It sprawled across both sides of the Mississippi River, beckoning visitors from all over the present-day Southern United States.

Cahokia seems to have been a place of spiritual pilgrimage, which drew diverse groups of Native American peoples, who spoke different languages and worshiped in various ways but came to share a reverence for this city and its ceremonial customs, which included human sacrifice. Its multiethnic, year-round population apparently serviced the religious pilgrims and, in the off-season, went about their own affairs.

Cahokia died not as a result of sudden catastrophe, like Pompeii, but seemingly because it lost its spiritual significance over time. Its people didn’t perish. The pilgrims just stopped coming; the local residents merged with other tribes. There is linguistic and other evidence that the Sioux are their descendants.

Newitz devotes space to debunking the popular notion that civilizations of the past “collapse” and become “lost,” pointing instead to indications of gradual change.

The operative lesson from the past, at least from this curated offering of former metropolises, seems to be that human culture is a plastic thing. Rather than lamenting the fragility of our current urban structures, we might do better figuring out how to bend and shape society for the future.

the effect of reading “Four Lost Cities” was more meditative. This is a long, long, long ride we are on. Much is beyond our control. Humanity trundles on.

The videos promoted narratives that Chinese technology was superior to America’s, that the United States was doomed to economic collapse, and that China and Russia were responsible geopolitical players. Some of the clips fawned over Chinese companies like Huawei and denigrated American companies like Apple.

Content from at least 30 channels in the network drew nearly 120 million views and 730,000 subscribers since last year, along with occasional ads from Western companies

Disinformation — such as the false claim that some Southeast Asian nations had adopted the Chinese yuan as their own currency — was common. The videos were often able to quickly react to current events

he coordinated campaign might be “one of the most successful influence operations related to China ever witnessed on social media.”

Historically, its influence operations have focused on defending the Communist Party government and its policies on issues like the persecution of Uyghurs or the fate of Taiwan

Efforts to push pro-China messaging have proliferated in recent years, but have featured largely low-quality content that attracted limited engagement or failed to sustain meaningful audiences

“This campaign actually leverages artificial intelligence, which gives it the ability to create persuasive threat content at scale at a very limited cost compared to previous campaigns we’ve seen,”

YouTube said in a statement that its teams work around the clock to protect its community, adding that “we have invested heavily in robust systems to proactively detect coordinated influence operations.” The company said it welcomed research efforts and that it had shut down several of the channels mentioned in the report for violating the platform’s policies.

China began targeting the United States more directly amid the mass pro-democracy protests in Hong Kong in 2019 and continuing with the Covid-19 pandemic, echoing longstanding Russian efforts to discredit American leadership and influence at home and aboard.

Over the summer, researchers at Microsoft and other companies unearthed evidence of inauthentic accounts that China employed to falsely accuse the United States of using energy weapons to ignite the deadly wildfires in Hawaii in August.

Meta announced last month that it removed 4,789 Facebook accounts from China that were impersonating Americans to debate political issues, warning that the campaign appeared to be laying the groundwork for interference in the 2024 presidential elections.

It was the fifth network with ties to China that Meta had detected this year, the most of any other country.

The advent of artificial technology seems to have drawn special interest from Beijing. Ms. Keast of the Australian institute said that disinformation peddlers were increasingly using easily accessible video editing and A.I. programs to create large volumes of convincing content.

She said that the network of pro-China YouTube channels most likely fed English-language scripts into readily available online text-to-video software or other programs that require no technical expertise and can produce clips within minutes. Such programs often allow users to select A.I.-generated voice narration and customize the gender, accent and tone of voice.

In 39 of the videos, Ms. Keast found at least 10 artificially generated avatars advertised by a British A.I. company

she also discovered what may be the first example in an influence operation of a digital avatar created by a Chinese company — a woman in a red dress named Yanni.

The scale of the pro-China network is probably even larger, according to the report. Similar channels appeared to target Indonesian and French people. Three separate channels posted videos about chip production that used similar thumbnail images and the same title translated into English, French and Spanish.

Melissa Carrion, a professor at the University of Nevada, Las Vegas, who studies the rhetoric of health and medicine, spoke to 50 mothers who had refused one or more vaccines for their children for a study published in 2017.“Across the board, every single one of them gave some variation of the advice that a mother ‘should do her own research,’” she said in a phone interview. “It was this kind of worldview that was less about the result of the research than the individual process of doing it themselves.”

One of the enticing aspects of cryptocurrencies, which pose an alternative to traditional financial institutions, is that expertise is available to anyone who wants to claim it. There are people who’ve gotten rich, people who know a lot about blockchains and people who believe in the liberating power of digital currencies. There is some recent institutional interest. But nobody’s been around very long, which makes the idea of “researching” your way to prosperity feel more credible.

Cryptocurrency trading, in contrast to medicine, might represent DYOR in pure no-expert form. Virtually everyone is operating in a beginners’ bubble, whether they’re worried about it or not, betting with and against one another, in hopes of making money.

ere, so-called research materials are often limited to a white paper, marketing materials and testimonials, the “due diligence” posts of others, the reputations of a currency’s creators and the general sentiment of other possible buyers. Will they buy-in, too? Will we take this coin to the moon?In that way — the momentum of a group — crypto investing isn’t altogether distinct from how people have invested in the stock market for decades. Though here it is tinged with a rebellious, anti-authoritarian streak: We’re outsiders, in this together; we’re doing something sort of ridiculous, but also sort of cool. Though DYOR may be used to foster a sense of community, what it actually describes is participation in a market.

A year ago, Luna boosters (and a few skeptics) in online forums offered the same advice to gathered audiences of potential buyers reading their posts, looking for tips: just DYOR. Thousands invested in both Luna and TerraUSD. The price of Luna climbed from around $5 to over $100. After the crash, at least one Reddit user suggested that the situation highlighted the “limit” of DYOR; the coin’s price had fallen to nearly zero.

Tesla, which had more than 99,000 employees at the end of last year, has moved its headquarters to Austin, Texas, from Palo Alto, Calif., though it still has a significant manufacturing and operational presence in California. SpaceX employs about 12,000 people, Mr. Musk said in a recent interview.

Annie Dean, the head of distributed work for Atlassian, an Australian software company, called Mr. Musk’s view “outdated.”

“This mind-set is regressive and discounts the last two years of collaborative, digital-first work,” said Ms. Dean, who was a former head of remote work at Meta, the owner of Facebook, in an email.

It is unclear if Mr. Musk will adhere to his own rules of spending 40 hours a week in Tesla’s and SpaceX’s offices. He is rarely in the office and often travels, said two people who have worked with him and who spoke on the condition of anonymity. They expressed concerns about how the return-to-office policies would affect recruiting and retention at the companies.

The fiscal response to Covid-19 reinforced this point: Money is a tool of social decision-making, not an objective thing that you get through abstract merit.

the value of cryptocurrency is so clearly socially constructed: A Bitcoin was worth roughly nothing a decade ago, and roughly $41,000 today, solely because people collectively decided to ascribe value to Bitcoin.

money gets its value from people agreeing that it’s valuable.

As of Friday Russia had about $630 billion of foreign currency reserves, a large cushion designed to allow it to withstand economic sanctions and prop up the value of the ruble

But “foreign currency reserves” are not an objective fact; they are mostly a series of entries on lists maintained by foreign-currency issuers and intermediaries (central banks, correspondent banks, sovereign bond issuers, brokerages). 1  If those people cross you off the list, or put an asterisk next to your entry freezing your funds, then you can’t use those funds anymore.

The bulk of Russia’s foreign reserves are held in the form of securities, deposits at other central banks and deposits at foreign commercial banks. A ban on transactions with Russia’s central bank means that it can’t sell those securities or access those deposits.

Now you want something for yourself? OK, but that is going to be subtracted from the running total of how much you’ve done for the rest for us.

There is a lot to dislike, or at least to be uncomfortable with, in this situation.

But the response to the 2008 global financial crisis, and to its later European aftershocks, made it clear that something else was going on. Who has money and what they can do with it can be adjusted by the actions of central banks and national treasuries; banks can be bailed out; costs can be socialized.

it is also arguably bad for global prosperity: Trustworthy rules-based trade works better and produces more value than arbitrary uncertain trade.

But what I want to suggest is that this weekend’s actions are evidence that the basic structure is good. What I want to suggest is that society is good, that it is good for people (and countries) to exist in a web of relationships in which their counterparties can judge their actions and punish bad actions.

If money is socially constructed and property is contingent then money is a continuing, dynamic, ever-at-risk reward for prosocial behavior.

one of the ways I suggest students think about money is as a kind of social scorecard.

You did something good — made something somebody wanted, let somebody else use something you own, went to work and did everything the boss told you? Good for you, you get a cookie. Or more precisely, you get a credit, in both senses, in the personal record kept for you at a bank.

This is arguably bad for the dollar’s long-run dominance: Russia will develop its own ways around SWIFT, China will push other countries to adopt its digital yuan, everyone will use Bitcoin, etc

we have exactly this system already. The number is called a bank account. The difference is simply that we have so naturalized the system that “how much money you have” seems like simply a fact about you, rather than a judgment imposed by society.

Pervasive social credit systems seem dystopian, and you would not really want the U.S. government making day-to-day decisions about who deserves to keep their bank accounts.

But another idea is that money can insulate you from  the obligations of society, and that is also bad.

You get a claim on goods and services by being part of society, and having a big number next to your name on a list does not relieve you of your obligations. If you do something so outrageous that society as a whole decides you are a pariah, then money is a way for society to express that.

North Korea produced an estimated 4.5 million tons of grain last year, dropping 3.8% from 2021, according to the South Korean government. South Korea’s spy agency has said North Korea needs about 5.5 million tons of grain to feed its population.

More than 10 million North Koreans suffered malnourishment and hunger during the pandemic, with 41% of the population undernourished between 2019 and 2021

About one-fifth of North Korean children suffer from impaired growt

North Korea spends nearly a quarter of its gross domestic product on its military, according to U.S. State Department estimates. The Kim regime spent between $340 million and $530 million on ballistic missile launches last year

Military officials didn’t receive food rations for their families during some months last year, he said. Pharmacies have only one-fifth of the medical supplies that they had before the pandemic, he said.

“The inability to provide for the military, the Kim regime’s most loyal support base, indicates that the food problem is very real,” Mr. Lee said.

The Ambassador Bridge is the busiest U.S.-Canadian border crossing, carrying 25% of all trade between the two countries.

The Freedom Convoy has been promoted and cheered on by many Fox News personalities and attracted support from the likes of former President Donald Trump.

On Friday, amid signs that authorities might be prepared to get tough, police in Windsor and Ottawa awaited reinforcements from the Royal Canadian Mounted Police, the federal police force.

Ottawa’s mayor has asked for 1,800 additional police officers, nearly doubling the manpower available to the the city’s police force, which has 2,100 officers and civilian members.

The reaction to the protests has also been marked by disagreements over who’s in charge. Canada’s emergency preparedness minister said this week that Ontario has ultimate responsibility, while the province’s transport minister said it is the federal government’s job to secure the border.

Also, the leadership of the opposition Conservative Party on the federal level has openly supported the truckers, apparently happy to make this Trudeau’s problem.

He also said the domestic cannabis industry had the potential to create 130,000 jobs and increase export revenues.

It has become an argument over a nominee who does not exist — one who does not respect America, is not truly religious, coddles child abusers and terrorists and has highly developed views about the importance of “woke” education.

Conspiracy theories and unfair accusations have a long history in American politics, of course. But they have often remained on the margins. Today, distortions and falsehoods have moved to the center of politics.

While neither party is entirely innocent, there is a fundamental difference between Republicans and Democrats. False claims regularly flow from the leaders of the Republican Party —

The Jackson hearings have become the latest example. Several Republican senators — including Josh Hawley, Lindsey Graham and Ted Cruz yesterday — have tried to portray her as soft on child pornographers. Their argument depends on a misleading cherry-picking of facts from cases she has heard.

Woke education has become another focus of the hearings, with Republicans like Cruz and Marsha Blackburn trying to portray Jackson as an advocate for it. In truth, she has not taken a position on the issues that fall under that category.

That was apparently enough for the Republican National Committee to tweet an image of her this week, with her initials — KBJ — crossed out and replaced with CRT, an abbreviation for critical race theory.

The only time Jackson appears to have mentioned critical race theory publicly was in a 2015 speech. It was part of a list of disciplines that she said had an intellectual connection to criminal sentencing, including administrative law, philosophy, psychology and statistics.

There is one broader political risk here for Democrats, though: imagining that Republicans are simply playing to their base by making these misleading criticisms of Jackson. They are also trying to appeal to swing voters.

Most Americans oppose cutting police budgets, for instance. Many believe that allowing all transgender girls to compete in girls’ sports can be unfair to other girls. Many voters — and not just white voters — think that liberals focus too much on racial identity.

“One thing that is striking about this hearing,” Lori Ringhand, a legal scholar, told The Times, “is how little effort we are seeing to engage the nominee on her views about actual legal issues.”

Leaders in the deeply conservative Utah say they need the law to protect women's sports. As cultural shifts raise LGBTQ visibility, the lawmakers argue that, without their intervention, more transgender athletes with apparent physical advantages could eventually dominate the field and change the nature of women's sports.

he team is also partially owned by NBA all-star Dwyane Wade, who has a transgender daughter.

The looming threat of a lawsuit worries school districts and the Utah High School Athletic Association, which has said it lacks the funds to defend the policy in court. Later Friday, lawmakers are expected to change the bill so state money would cover legal fees.

The group Visit Salt Lake, which hosts conferences, shows and events, said the override could cost the state $50 million in lost revenue. The Utah-based DNA-testing genealogy giant Ancestry.com also urged the Legislature to find another way. The American Principles Project is confident that states with bans won't face boycotts like North Carolina did after limiting public restrooms transgender people could use. It focused on legislation in populous, economic juggernaut states like Texas and Florida that would be harder to boycott, Schilling said.

Friday's deliberations came after more than a year of debate and negotiation between social conservatives and LGBTQ advocates. Republican sponsor Rep. Kera Birkeland worked with Cox and civil rights activists at Equality Utah before introducing legislation that would require transgender student-athletes to go before a government-appointed commission.

The proposal, although framed as a compromise, failed to gain traction on either side. LGBTQ advocates took issue with Republican politicians appointing commission members and evaluation criteria that included body measurements such as hip-to-knee ratio.

But the ban won support from a vocal conservative base that has particular sway in Utah's state primary season. Even with primaries looming, however, some Republicans stood with Cox to reject the ban.

Ready for more bad infectious diseases news? There's an outbreak of bird flu making its way into U.S. poultry flocks. If the virus continues to spread, it could affect poultry prices — already higher amid widespread inflation. The price of chicken breasts this week averaged $3.63 per pound at U.S. supermarkets — up from $3.01 a week earlier and $2.42 at this time last year, the Agriculture Department says.

The latest data from the USDA show 59 confirmed sites of avian flu across commercial and backyard flocks in 17 states since the start of the year. That figure includes chickens, turkey and other poultry. The USDA identified a case of avian flu in a wild bird in mid-January, the first detection of the virus in wild birds in the U.S. since 2016. Wild birds can spread the virus to commercial and backyard flocks. By Feb. 9, the virus had been identified in a commercial flock in Indiana.

The last major avian flu outbreak in the U.S. was from December 2014 to June 2015, when more than 50 million chickens and turkeys either died from highly pathogenic avian influenza (HPAI) or were destroyed to stop its spread.

Whether the 2022 avian flu will affect the price of eggs and poultry depends on how widespread it becomes, says Ron Kean, a poultry science expert at the University of Wisconsin-Madison Department of Animal and Dairy Sciences. "In 2015, we did see quite an increase in egg prices," Kean told Wisconsin Public Radio. "The chicken meat wasn't severely affected at that time. We did see quite a loss in turkeys, so turkey prices went up. So, we'll see. If a lot of farms contract this, then we could see some real increases in price."

For producers who suspect their flock may be affected by avian flu, the USDA has a guide to the warning signs, including a sudden increase in bird deaths, lack of energy and appetite, and a decrease in egg production. If a flock is found to be infected by bird flu, the USDA moves quickly — within 24 hours — to assist producers to destroy the flock and prevent the virus from spreading.

A new Virginia state law prohibiting mask mandates in public schools does not apply to 12 students with disabilities whose parents challenged the law, a federal judge has ruled. Last month, the parents of 12 students across Virginia asked the court to halt enforcement of the law, saying it violated their rights under the federal American with Disabilities Act. The law, signed by newly elected Republican Gov. Glenn Youngkin, went into effect March 1; it gives parents a say over whether their children should wear masks in school.

The group of parents have children whose health conditions range from cystic fibrosis to asthma that put them at heightened risk for COVID-19.

The American Civil Liberties Union, which was one of several legal organizations that filed on behalf of the plaintiffs, said the injunction served as a "blueprint."

In a statement, Virginia Attorney General Jason Miyares said the ruling affirms that "parents have the right to make choices for their children."

When Judge Katanji Brown Jackson entered the Senate chamber this week to face questions on her readiness to join the Supreme Court, she did so as the first Black woman in the nation's history to be nominated to that position. For many Black law students and professionals, including a group of 150 who traveled from across the country to watch the historic hearing, Jackson's rise to likely associate justice gives a message of profound hope for what they too might one day be able to accomplish.

Dudley was one of 100 law students selected nationwide to attend a series of events and watch parties for Jackson's nomination, hosted by the progressive organization, Demand Justice. The group also included 50 public defenders — a nod to Jackson's own background in that field. "I see a lot of myself in her. I see a lot of my friends in her, and I wanted to be there to support," Dudley said, calling Jackson "overly qualified to sit on the Supreme Court."

The cohort of legal professionals cheered on Jackson as she faced questions from Republicans about her past cases, particularly those relating to child sex abuse, and on what school of thought she would bring to determining the constitutionality of high-profile cases. Republicans had vowed to oppose President Joe Biden's nominees to the court, and when news of Justice Stephen Breyer's imminent retirement broke, the GOP quickly mobilized to attack potential nominees who might replace the longtime liberal justice on the bench.

Particularly, some sentencing decisions in child pornography cases drew GOP fire. But Jackson's measured responses throughout the three days of questioning solidified the support of many onlookers, who reveled in what it would mean to have a Black woman sit on the bench for the first time in the court's 233-year history. "The fact of the matter is that I'm the father of three black girls, right? And to be able to tell them that finally, someone who is Black — female nonetheless — is finally on the precipice of a mountain that has never been climbed before by any other Black woman, is huge," said Edrius Stagg, a third-year law student at Southern University Law Center in Baton Rouge.

Sen. Joe Manchin of West Virginia — whose break from Democrats on a number of politically fraught votes had worried some as to whether he would support Biden's nominee — announced on Friday he would vote in favor of Jackson's confirmation, all but assuring her path to join the bench.

For some, the optics of seeing Jackson — a Black woman — defend her credentials to a group of largely white, predominantly male detractors, was a familiar scene. It has played out, students said, in workplaces the world over and across the socioeconomic spectrum.

Booker called the attacks on Jackson's record "dangerous" and "disingenuous," noting the complexities of cases that had been boiled down to their basest points in order to damage Jackson's image.

"I'm not gonna let my joy be stolen," he continued. "Because I know, you and I, we appreciate something that we get that a lot of my colleagues don't." And while Jackson's opponents peppered her with politically polarizing questions, her supporters grew even more convinced that Jackson was qualified for the job. "To see her hold her composure and just answer the questions just to the best of her capabilities was just really great to see," said Jasmine McMillion, a third-year law student at Florida Agricultural and Mechanical University College of Law.

Jansen's fascination with medicine began at a young age, thanks to her father's ability to cure her frequent throat infections and coughs. "You're a small person, and you have this violent cough, and you feel sick as a dog," she recalls. "And then you get this drug. And it makes you feel better."

A few years after earning her Ph.D. in 1984, Jansen accepted a job at Merck's vaccine division. Her first challenge was to create a vaccine for the human papillomavirus, which was believed to cause cervical cancer in the 1980s. Jansen faced significant opposition, both from researchers — who thought the vaccine would not work— and Merck's finance gurus — who believed it would not be profitable. But she persisted. The Gardasil vaccine, approved in 2006, now earns Merck billions of dollars annually.

Yet would people vote for a politician honest enough to say these things? No. We force them to lie then complain they’re liars. It is we who are the hypocrites. Whence comes this persistent, subterranean sense of British entitlement, even as the economy on which it depends begins to sink?

The elastication of any link between what we demand and our ability to afford it began long ago but it has been sharply accelerated by the Covid-19 lockdowns: by the idea we could retreat into our living rooms and expect public money to come feathering electronically down into our bank accounts like falling leaves from the Treasury’s magic money tree, until it was safe to go back to work. To this day many haven’t even bothered to do that, as early pensions replace furlough.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.”

American health experts advocated almost universal child vaccination; meanwhile, in Europe, experts cautioned against vaccinating young children, who were at low risk for serious illness, without more long-term data. “Were we pushing to vaccinate children for their sake or for ours?” Galea asks. “Were we doing it to support health or to make a political point?”

Scientists should have made more nuanced risk assessments and revisited them regularly. They should have taken into account the consequences and the disproportionate impact of strict lockdowns on lower-income workers and at-risk youth

This zero-sum mode of thinking — neglecting to take into account one’s own biases, succumbing to groupthink, operating according to the expectations of one’s “side,” discouraging good-faith debate — persisted even as the pandemic eased.

this tendency to view “core issues in Manichaean terms, with certain positions seen as on the side of good and others on the side of evil, with little gray area between,” as Galea puts it, has continued to inform public health postpandemic

It also undermines public faith in science, one of the few institutions that had maintained a high level of trust into the Trump era.

the percentage of Americans who believe science has a mostly positive effect on society dropped to 57 percent in 2023, from 67 percent in 2016. Those who say they have a great deal of confidence in scientists dropped to 23 percent, from 39 percent in 2020. And these declines took place among both Republicans and Democrats.

tern praised Joe Biden for “an extraordinarily good first term”, including the Inflation Reduction Act, which he called “far and away the most significant climate legislation ever in the US, and it’s quite powerful”.

Leaders who claimed to be grownups by saying the pace of action had to be slowed had to be honest about the alternatives, he said. Just as political leaders took swift action to prevent the spread of Covid-19 in 2020, so must they confront the consequences of slowing climate action now.

“He will try to reverse whatever he can in terms of domestic policy [on climate action],” he warned. “I don’t think anybody else is going to pull out of Paris because of Trump, but it’s highly disruptive to what can happen internationally, because the US is a very big, very important player. So [without the US] you don’t move as fast.”

Stern called for stronger demonstration from civil society of support for climate action. “What we need, broadly, is normative change, a shift in hearts and minds that demonstrates to political leaders that their political future depends on taking strong, unequivocal action to protect our world,” he said.

“Normative change may seem at first blush like a weak reed to carry into battle against the defenders of the status quo, but norms can move mountains. They are about a sense of what is right, what is acceptable, what is important, what we expect and what we demand.”
