Their policies tend to please no one; it’s a common refrain that antipathy toward Big Tech companies is one of the few truly bipartisan issues

You can just feel it, the cumulative weight of this stagnation, in the tech that most of us encounter every day. The act of scrolling past the same dumb ad to peer at the same bad news on the same glass screen on the same social network: This is the stuck future. There is a sense that we have reached the end of the internet, and no one wants to be left holding the bag

There’s a palpable exhaustion with the whole enterprise, with the men who set out to build the future or at least get rich, and who accomplished only one and a half of those things.

YouTube, meanwhile, is facing many of the same policy quagmires as Facebook and Twitter, especially when it comes to content moderation—and similarly failing to meaningfully address them.

It’s not just social media that’s in decline, already over, or worse.

As its mighty iPhone sales figures have plateaued and its business has grown more conservative—it hasn’t released a culturally significant new product line since 2016’s AirPods—Apple has begun to embrace advertising.

as Google has consolidated its monopoly, the quality of its flagship search product has gotten worse. Result pages are cluttered with ads that must be scrolled through in order to find the “‘organic”’ items, and there’s reason to think the quality of the results has gotten worse over time as well.

The big social networks are stuck. And there is little profit incentive to get them unstuck. That, after all, would require investing heavily in content moderators, empowering trust and safety teams, and penalizing malicious viral content that brings in huge traffic.

What a grim outcome for the internet, where the possibilities were once believed to be endless and where users were promised an infinite spectrum of possibility to indulge their creativity, build robust communities, and find their best expression, even when they could not do so in the real world

Big Tech, of course, never predicated its business models on enabling any of that, though its advertising and sloganeering may have suggested otherwise. Rather, companies’ ambitions were always focused on being the biggest: having the most users, selling the most devices, locking the most people into their walled gardens and ecosystems. The stuckness we’re seeing is the result of some of the most ambitious companies of our generation succeeding wildly yet having no vision beyond scale—no serious interest in engaging the civic and social dimensions of their projects.

Three years since its start we are still more likely to see the pandemic in partisan rather than world-historical terms. And the grandly tragic story of the pandemic takes on a profoundly different shape and color depending on the nature of its first act.

In a world where a natural origin was confirmed beyond all doubt, we might look back and narrate the pandemic as one particular kind of story: a morality tale showcasing the incomplete triumph of modern civilization and the enduring threats from nature, and highlighting the way that, whatever we might have told ourselves in 2019 or 2009 about the fortress of the wealthy world, pandemic disease remained a humbling civilization-scale challenge no nation had very good answers for.

in a world where a lab-leak origin had been confirmed instead, we would probably find ourselves telling a very different set of stories — primarily about humanity’s Icarian hubris, or perhaps about scientists’ Faustian indifference to the downside risks of new research, or the way in which very human impulses to cover up mistakes and wrongdoing might have compounded those mistakes to disastrous global effect.

It would have been, “We brought this on ourselves.” Or perhaps, if we were feeling xenophobic rather than humbly human, “They brought this on us,”

the pandemic would probably have joined nuclear weapons as a conventional illustration of the dark side of human knowledge, perhaps even surpassed them — 20 million dead is nothing to trifle with, after all, though it remains less than the overall death toll of World War II or even the Great Leap Forward.

the horror would also offer a silver lining: If human action was responsible for this pandemic, then in theory, human action could prevent the next one as well.

if the figures are even mostly reliable, they reflect a remarkable indifference on the part of the country to the source of a once-in-a-century disease disaster

It is as though we’ve decided both that the pandemic was “man-made” and that its emergence was a kind of inevitability we can’t do much about.

a definitive confirmation of a lab origin probably would not mean that responsibility lay in any simplistic way with China. But that isn’t to say the case wouldn’t have been made, probably in a variety of forms — calls for “reparations,” demands for global provision of free vaccines — that would only have contributed additional antagonism and resentment to the world stage, further polarizing the great-power landscape.

It would be as though following a catastrophic earthquake, we didn’t bother to sort out whether it had been caused by local fracking but instead argued endlessly about the imperfections of disaster response

as we piece together a working history of the past few years, you might hope we’d grow more focused on nailing the story down.

it seems likely to me that in the very earliest days of 2020, with cases exploding in China but not yet elsewhere, knowing that the disease was a result of gain-of-function research and had escaped from a lab probably would have produced an even more significant wave of global fear

n a world where neither narrative has been confirmed, and where pandemic origins are governed by an epistemological fog, I worry we have begun to collate the two stories in a somewhat paradoxical and self-defeating way

presumably, many fewer people contemplating the initial news would’ve assumed that the outbreak would be largely limited to Asia, as previous outbreaks had been; public health messengers in places like the United States probably would not have so casually reassuring; and even more dramatic circuit-breaking responses like a monthlong international travel ban might’ve been instituted quite quickly

As the pandemic wore on, I suspect that effect would have lingered beyond the initial panic. At first, it might’ve been harder to decide that the virus was just something to live with if we knew simultaneously that it was something introduced to the world in error.

And later, when the vaccines arrived, I suspect there might have been considerably less resistance to them, particularly on the American right, where anxiety and xenophobia might have trumped public-health skepticism and legacy anti-vaccine sentiment

the opposite counterfactual is just as illuminating

The question and its unresolvability have mattered enormously for geopolitics,

it is hard to think “superbug” and not panic.

The disease and global response may well have accelerated our “new Cold War,” as Luce writes, but it is hard to imagine an alternate history where a known lab-leak origin didn’t move the world there much faster.

On the other hand, the natural logic of a confirmed zoonotic origin would probably have been to push nations of the world closer together into networks of collaboration and cooperation

the direction of change would have most likely been toward more integration rather than less. After all, this is to some degree what happened in the wake of the initial outbreaks of SARS and MERS and the Ebola outbreaks of the past decade.

Instead, the geopolitics remain unsteady, which is to say, a bit jagged

The United States can weaponize a narrative about lab origin — as China hawks in both the Trump and Biden administrations have repeatedly done — without worrying too much about providing real proof or suffering concrete backlash.

And China can stonewall origin investigations by citing sovereignty rights and a smoke screen story about the disease originating in frozen food shipped in from abroad without paying much of an international price for the intransigence or bad-faith argumentation, either.

each has carried forward a gripe that needn’t be substantiated in order to be deployed.

ambiguity also offers plausible deniability, which means that without considerably more Chinese transparency and cooperation, those pushing both stories will find themselves still making only probabilistic cases. We’re probably going to be living with that uncertainty, in a political and social world shaped by it, for the foreseeable future

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.”

The ordinary fixes—the kind that draw on people’s will, and require eating less and moving more—rarely have a large or lasting effect. Indeed, America itself has suffered through a long, maddening history of failed attempts to change its habits on a national scale: a yo-yo diet of well-intentioned treatments, policies, and other social interventions that only ever lead us back to where we started

Through it all, obesity rates keep going up; the diabetes epidemic keeps worsening.

The most recent miracle, for Barb as well as for the nation, has come in the form of injectable drugs. In early 2021, the Danish pharmaceutical company Novo Nordisk published a clinical trial showing remarkable results for semaglutide, now sold under the trade names Wegovy and Ozempic.

Patients in the study who’d had injections of the drug lost, on average, close to 15 percent of their body weight—more than had ever been achieved with any other drug in a study of that size. Wadden knew immediately that this would be “an incredible revolution in the treatment of obesity.”

Many more drugs are now racing through development: survodutide, pemvidutide, retatrutide. (Among specialists, that last one has produced the most excitement: An early trial found an average weight loss of 24 percent in one group of participants.

In the United States, an estimated 189 million adults are classified as having obesity or being overweight

The drugs don’t work for everyone. Their major side effects—nausea, vomiting, and diarrhea—can be too intense for many patients. Others don’t end up losing any weight

For the time being, just 25 percent of private insurers offer the relevant coverage, and the cost of treatment—about $1,000 a month—has been prohibitive for many Americans.

The drugs have already been approved not just for people with diabetes or obesity, but for anyone who has a BMI of more than 27 and an associated health condition, such as high blood pressure or cholesterol. By those criteria, more than 140 million American adults already qualify

if this story goes the way it’s gone for other “risk factor” drugs such as statins and antihypertensives, then the threshold for prescriptions will be lowered over time, inching further toward the weight range we now describe as “normal.”

How you view that prospect will depend on your attitudes about obesity, and your tolerance for risk

The first GLP-1 drug to receive FDA approval, exenatide, has been used as a diabetes treatment for more than 20 years. No long-term harms have been identified—but then again, that drug’s long-term effects have been studied carefully only across a span of seven years

the data so far look very good. “These are now being used, literally, in hundreds of thousands of people across the world,” she told me, and although some studies have suggested that GLP-1 drugs may cause inflammation of the pancreas, or even tumor growth, these concerns have not borne out.

adolescents are injecting newer versions of these drugs, and may continue to do so every week for 50 years or more. What might happen over all that time?

“All of us, in the back of our minds, always wonder, Will something show up?  ” Although no serious problems have yet emerged, she said, “you wonder, and you worry.”

in light of what we’ve been through, it’s hard to see what other choices still remain. For 40 years, we’ve tried to curb the spread of obesity and its related ailments, and for 40 years, we’ve failed. We don’t know how to fix the problem. We don’t even understand what’s really causing it. Now, again, we have a new approach. This time around, the fix had better work.

The fen-phen revolution arrived at a crucial turning point for Wadden’s field, and indeed for his career. By then he’d spent almost 15 years at the leading edge of research into dietary interventions, seeing how much weight a person might lose through careful cutting of their calories.

But that sort of diet science—and the diet culture that it helped support—had lately come into a state of ruin. Americans were fatter than they’d ever been, and they were giving up on losing weight. According to one industry group, the total number of dieters in the country declined by more than 25 percent from 1986 to 1991.

Rejecting diet culture became something of a feminist cause. “A growing number of women are joining in an anti-diet movement,” The New York Times reported in 1992. “They are forming support groups and ceasing to diet with a resolve similar to that of secretaries who 20 years ago stopped getting coffee for their bosses.

Now Wadden and other obesity researchers were reaching a consensus that behavioral interventions might produce in the very best scenario an average lasting weight loss of just 5 to 10 percent

National surveys completed in 1994 showed that the adult obesity rate had surged by more than half since 1980, while the proportion of children classified as overweight had doubled. The need for weight control in America had never seemed so great, even as the chances of achieving it were never perceived to be so small.

Wadden wasn’t terribly concerned, because no one in his study had reported any heart symptoms. But ultrasounds revealed that nearly one-third of them had some degree of leakage in their heart valves. His “cure for obesity” was in fact a source of harm.

In December 1994, the Times ran an editorial on what was understood to be a pivotal discovery: A genetic basis for obesity had finally been found. Researchers at Rockefeller University were investigating a molecule, later named leptin, that gets secreted from fat cells and travels to the brain, and that causes feelings of satiety. Lab mice with mutations in the leptin gene—importantly, a gene also found in humans—overeat until they’re three times the size of other mice. “The finding holds out the dazzling hope,”

In April 1996, the doctors recommended yes: Dexfenfluramine was approved—and became an instant blockbuster. Patients received prescriptions by the hundreds of thousands every month. Sketchy wellness clinics—call toll-free, 1-888-4FEN-FEN—helped meet demand. Then, as now, experts voiced concerns about access. Then, as now, they worried that people who didn’t really need the drugs were lining up to take them. By the end of the year, sales of “fen” alone had surpassed $300 million.

It was nothing less than an awakening, for doctors and their patients alike. Now a patient could be treated for excess weight in the same way they might be treated for diabetes or hypertension—with a drug they’d have to take for the rest of their life.

the article heralded a “new understanding of obesity as a chronic disease rather than a failure of willpower.”

News had just come out that, at the Mayo Clinic in Minnesota, two dozen women taking fen-phen—including six who were, like Barb, in their 30s—had developed cardiac conditions. A few had needed surgery, and on the operating table, doctors discovered that their heart valves were covered with a waxy plaque.

Americans had been prescribed regular fenfluramine since 1973, and the newer drug, dexfenfluramine, had been available in France since 1985. Experts took comfort in this history. Using language that is familiar from today’s assurances regarding semaglutide and other GLP-1 drugs, they pointed out that millions were already on the medication. “It is highly unlikely that there is anything significant in toxicity to the drug that hasn’t been picked up with this kind of experience,” an FDA official named James Bilstad would later say in a Time cover story headlined “The Hot New Diet Pill.

“I know I can’t get any more,” she told Williams. “I have to use up what I have. And then I don’t know what I’m going to do after that. That’s the problem—and that is what scares me to death.” Telling people to lose weight the “natural way,” she told another guest, who was suggesting that people with obesity need only go on low-carb diets, is like “asking a person with a thyroid condition to just stop their medication.”

She’d gone off the fen-phen and had rapidly regained weight. “The voices returned and came back in a furor I’d never heard before,” Barb later wrote on her blog. “It was as if they were so angry at being silenced for so long, they were going to tell me 19 months’ worth of what they wanted me to hear. I was forced to listen. And I ate. And I ate. And ate.”

For Barb, rapid weight loss has brought on a different metaphysical confusion. When she looks in the mirror, she sometimes sees her shape as it was two years ago. In certain corners of the internet, this is known as “phantom fat syndrome,” but Barb dislikes that term. She thinks it should be called “body integration syndrome,” stemming from a disconnect between your “larger-body memory” and “smaller-body reality.

In 2003, the U.S. surgeon general declared obesity “the terror within, a threat that is every bit as real to America as the weapons of mass destruction”; a few months later, Eric Finkelstein, an economist who studies the social costs of obesity, put out an influential paper finding that excess weight was associated with up to $79 billion in health-care spending in 1998, of which roughly half was paid by Medicare and Medicaid. (Later he’d conclude that the number had nearly doubled in a decade.

In 2004, Finkelstein attended an Action on Obesity summit hosted by the Mayo Clinic, at which numerous social interventions were proposed, including calorie labeling in workplace cafeterias and mandatory gym class for children of all grades.

he message at their core, that soda was a form of poison like tobacco, spread. In San Francisco and New York, public-service campaigns showed images of soda bottles pouring out a stream of glistening, blood-streaked fat. Michelle Obama led an effort to depict water—plain old water—as something “cool” to drink.

Soon, the federal government took up many of the ideas that Brownell had helped popularize. Barack Obama had promised while campaigning for president that if America’s obesity trends could be reversed, the Medicare system alone would save “a trillion dollars.” By fighting fat, he implied, his ambitious plan for health-care reform would pay for itself. Once he was in office, his administration pulled every policy lever it could.

Michelle Obama helped guide these efforts, working with marketing experts to develop ways of nudging kids toward better diets and pledging to eliminate “food deserts,” or neighborhoods that lacked convenient access to healthy, affordable food. She was relentless in her public messaging; she planted an organic garden at the White House and promoted her signature “Let’s Move!” campaign around the country.

An all-out war on soda would come to stand in for these broad efforts. Nutrition studies found that half of all Americans were drinking sugar-sweetened beverages every day, and that consumption of these accounted for one-third of the added sugar in adults’ diets. Studies turned up links between people’s soft-drink consumption and their risks for type 2 diabetes and obesity. A new strand of research hinted that “liquid calories” in particular were dangerous to health.

when their field lost faith in low-calorie diets as a source of lasting weight loss, the two friends went in opposite directions. Wadden looked for ways to fix a person’s chemistry, so he turned to pharmaceuticals. Brownell had come to see obesity as a product of our toxic food environment: He meant to fix the world to which a person’s chemistry responded, so he started getting into policy.

The social engineering worked. Slowly but surely, Americans’ lamented lifestyle began to shift. From 2001 to 2018, added-sugar intake dropped by about one-fifth among children, teens, and young adults. From the late 1970s through the early 2000s, the obesity rate among American children had roughly tripled; then, suddenly, it flattened out.

although the obesity rate among adults was still increasing, its climb seemed slower than before. Americans’ long-standing tendency to eat ever-bigger portions also seemed to be abating.

sugary drinks—liquid candy, pretty much—were always going to be a soft target for the nanny state. Fixing the food environment in deeper ways proved much harder. “The tobacco playbook pretty much only works for soda, because that’s the closest analogy we have as a food item,

that tobacco playbook doesn’t work to increase consumption of fruits and vegetables, he said. It doesn’t work to increase consumption of beans. It doesn’t work to make people eat more nuts or seeds or extra-virgin olive oil.

Careful research in the past decade has shown that many of the Obama-era social fixes did little to alter behavior or improve our health. Putting calorie labels on menus seemed to prompt at most a small decline in the amount of food people ate. Employer-based wellness programs (which are still offered by 80 percent of large companies) were shown to have zero tangible effects. Health-care spending, in general, kept going up.

From the mid-1990s to the mid-2000s, the proportion of adults who said they’d experienced discrimination on account of their height or weight increased by two-thirds, going up to 12 percent. Puhl and others started citing evidence that this form of discrimination wasn’t merely a source of psychic harm, but also of obesity itself. Studies found that the experience of weight discrimination is associated with overeating, and with the risk of weight gain over time.

obesity rates resumed their ascent. Today, 20 percent of American children have obesity. For all the policy nudges and the sensible revisions to nutrition standards, food companies remain as unfettered as they were in the 1990s, Kelly Brownell told me. “Is there anything the industry can’t do now that it was doing then?” he asked. “The answer really is no. And so we have a very predictable set of outcomes.”

she started to rebound. The openings into her gastric pouch—the section of her stomach that wasn’t bypassed—stretched back to something like their former size. And Barb found ways to “eat around” the surgery, as doctors say, by taking food throughout the day in smaller portions

Bariatric surgeries can be highly effective for some people and nearly useless for others. Long-term studies have found that 30 percent of those who receive the same procedure Barb did regain at least one-quarter of what they lost within two years of reaching their weight nadir; more than half regain that much within five years.

if the effects of Barb’s surgery were quickly wearing off, its side effects were not: She now had iron, calcium, and B12 deficiencies resulting from the changes to her gut. She looked into getting a revision of the surgery—a redo, more or less—but insurance wouldn’t cover it

She found that every health concern she brought to doctors might be taken as a referendum, in some way, on her body size. “If I stubbed my toe or whatever, they’d just say ‘Lose weight.’ ” She began to notice all the times she’d be in a waiting room and find that every chair had arms. She realized that if she was having a surgical procedure, she’d need to buy herself a plus-size gown—or else submit to being covered with a bedsheet when the nurses realized that nothing else would fit.

Barb grew angrier and more direct about her needs—You’ll have to find me a different chair, she started saying to receptionists. Many others shared her rage. Activists had long decried the cruel treatment of people with obesity: The National Association to Advance Fat Acceptance had existed, for example, in one form or another, since 1969; the Council on Size & Weight Discrimination had been incorporated in 1991. But in the early 2000s, the ideas behind this movement began to wend their way deeper into academia, and they soon gained some purchase with the public.

“Our public-health efforts to address obesity have failed,” Eric Finkelstein, the economist, told me.

Others attacked the very premise of a “healthy weight”: People do not have any fundamental need, they argued, morally or medically, to strive for smaller bodies as an end in itself. They called for resistance to the ideology of anti-fatness, with its profit-making arms in health care and consumer goods. The Association for Size Diversity and Health formed in 2003; a year later, dozens of scholars working on weight-related topics joined together to create the academic field of fat studies.

As the size-diversity movement grew, its values were taken up—or co-opted—by Big Business. Dove had recently launched its “Campaign for Real Beauty,” which included plus-size women. (Ad Age later named it the best ad campaign of the 21st century.) People started talking about “fat shaming” as something to avoid

By 2001, Bacon, who uses they/them pronouns, had received their Ph.D. and finished a rough draft of a book, Health at Every Size, which drew inspiration from a broader movement by that name among health-care practitioners

But something shifted in the ensuing years. In 2007, Bacon got a different response, and the book was published. Health at Every Size became a point of entry for a generation of young activists and, for a time, helped shape Americans’ understanding of obesity.

Some experts were rethinking their advice on food and diet. At UC Davis, a physiologist named Lindo Bacon who had struggled to overcome an eating disorder had been studying the effects of “intuitive eating,” which aims to promote healthy, sustainable behavior without fixating on what you weigh or how you look

The heightened sensitivity started showing up in survey data, too. In 2010, fewer than half of U.S. adults expressed support for giving people with obesity the same legal protections from discrimination offered to people with disabilities. In 2015, that rate had risen to three-quarters.

In Bacon’s view, the 2000s and 2010s were glory years. “People came together and they realized that they’re not alone, and they can start to be critical of the ideas that they’ve been taught,” Bacon told me. “We were on this marvelous path of gaining more credibility for the whole Health at Every Size movement, and more awareness.”

that sense of unity proved short-lived; the movement soon began to splinter. Black women have the highest rates of obesity, and disproportionately high rates of associated health conditions. Yet according to Fatima Cody Stanford, an obesity-medicine physician at Harvard Medical School, Black patients with obesity get lower-quality care than white patients with obesity.

That system was exactly what Bacon and the Health at Every Size movement had set out to reform. The problem, as they saw it, was not so much that Black people lacked access to obesity medicine, but that, as Bacon and the Black sociologist Sabrina Strings argued in a 2020 article, Black women have been “specifically targeted” for weight loss, which Bacon and Strings saw as a form of racism

But members of the fat-acceptance movement pointed out that their own most visible leaders, including Bacon, were overwhelmingly white. “White female dietitians have helped steal and monetize the body positive movement,” Marquisele Mercedes, a Black activist and public-health Ph.D. student, wrote in September 2020. “And I’m sick of it.”

Tensions over who had the standing to speak, and on which topics, boiled over. In 2022, following allegations that Bacon had been exploitative and condescending toward Black colleagues, the Association for Size Diversity and Health expelled them from its ranks and barred them from attending its events.

As the movement succumbed to in-fighting, its momentum with the public stalled. If attitudes about fatness among the general public had changed during the 2000s and 2010s, it was only to a point. The idea that some people can indeed be “fit but fat,” though backed up by research, has always been a tough sell.

Although Americans had become less inclined to say they valued thinness, measures of their implicit attitudes seemed fairly stable. Outside of a few cities such as San Francisco and Madison, Wisconsin, new body-size-discrimination laws were never passed.

In the meantime, thinness was coming back into fashion

In the spring of 2022, Kim Kardashian—whose “curvy” physique has been a media and popular obsession—boasted about crash-dieting in advance of the Met Gala. A year later, the model and influencer Felicity Hayward warned Vogue Business that “plus-size representation has gone backwards.” In March of this year, the singer Lizzo, whose body pride has long been central to her public persona, told The New York Times that she’s been trying to lose weight. “I’m not going to lie and say I love my body every day,” she said.

Among the many other dramatic effects of the GLP-1 drugs, they may well have released a store of pent-up social pressure to lose weight.

If ever there was a time to debate that impulse, and to question its origins and effects, it would be now. But Puhl told me that no one can even agree on which words are inoffensive. The medical field still uses obesity, as a description of a diagnosable disease. But many activists despise that phrase—some spell it with an asterisk in place of the e—and propose instead to reclaim fat.

Everyone seems to agree on the most important, central fact: that we should be doing everything we can to limit weight stigma. But that hasn’t been enough to stop the arguing.

Things feel surreal these days to just about anyone who has spent years thinking about obesity. At 71, after more than four decades in the field, Thomas Wadden now works part-time, seeing patients just a few days a week. But the arrival of the GLP-1 drugs has kept him hanging on for a few more years, he said. “It’s too much of an exciting period to leave obesity research right now.”

When everyone is on semaglutide or tirzepatide, will the soft-drink companies—Brownell’s nemeses for so many years—feel as if a burden has been lifted? “My guess is the food industry is probably really happy to see these drugs come along,” he said. They’ll find a way to reach the people who are taking GLP‑1s, with foods and beverages in smaller portions, maybe. At the same time, the pressures to cut back on where and how they sell their products will abate.

the triumph in obesity treatment only highlights the abiding mystery of why Americans are still getting fatter, even now

Perhaps one can lay the blame on “ultraprocessed” foods, he said. Maybe it’s a related problem with our microbiomes. Or it could be that obesity, once it takes hold within a population, tends to reproduce itself through interactions between a mother and a fetus. Others have pointed to increasing screen time, how much sleep we get, which chemicals are in the products that we use, and which pills we happen to take for our many other maladies.

“The GLP-1s are just a perfect example of how poorly we understand obesity,” Mozaffarian told me. “Any explanation of why they cause weight loss is all post-hoc hand-waving now, because we have no idea. We have no idea why they really work and people are losing weight.”

The new drugs—and the “new understanding of obesity” that they have supposedly occasioned—could end up changing people’s attitudes toward body size. But in what ways

When the American Medical Association declared obesity a disease in 2013, Rebecca Puhl told me, some thought “it might reduce stigma, because it was putting more emphasis on the uncontrollable factors that contribute to obesity.” Others guessed that it would do the opposite, because no one likes to be “diseased.”

why wasn’t there another kind of nagging voice that wouldn’t stop—a sense of worry over what the future holds? And if she wasn’t worried for herself, then what about for Meghann or for Tristan, who are barely in their 40s? Wouldn’t they be on these drugs for another 40 years, or even longer? But Barb said she wasn’t worried—not at all. “The technology is so much better now.” If any problems come up, the scientists will find solutions.

People might not agree on much, Chandler says, but the “veil of ignorance” encourages us to find a mutually agreeable starting point. If we don’t know what community we are born into, we should want a “reasonable pluralism.” We should also want the state “to maintain the conditions that are the basis for our freedom and equality as citizens.”

As an example, Chandler raises the thorny issue of free speech. “Political, moral and religious” speech “is integral to developing our sense of what is fair and how to live,” he writes, which is why it deserves robust protection. But since some speech, such as advertising, plays “no meaningful role” in helping us figure out how to live a good life, such speech can be limited. The idea is to balance individual and group freedoms with the need for peaceful coexistence

The state should protect the rights of gay people not to be discriminated against — even though the state cannot force anyone or any group to approve of gay relationships. Chandler, who is gay, suggests that premising gay rights on getting everyone to agree on the question of morality is a waste of energy: “For some people this” — the belief that homosexuality is a sin — “is part of their faith and no reasoned argument will persuade them otherwise.”

The last two-thirds of “Free and Equal” are given over to specific policy proposals. Some of them sound familiar enough — restricting private money in politics; beefing up civic education — while others are more far-reaching and radical, including the establishment of worker cooperatives, in which “workers decide how things are done,” and the abolition of private schools.

t despite his valiant efforts, the book enacts both the promise and the limitations of the theory it seeks to promote. It didn’t leave me cold, but it did leave me restless.

He persuasively refutes the conflation of liberal egalitarianism with technocracy, and helpfully points out that an emphasis on technocratic competence “leaves many voters cold.

For anyone who venerates consensus in politics, this sounds appealing; given the fissures of our current moment, it also comes across as wildly insufficient.

that’s part of Chandler’s point: A Rawlsian framework encourages people with a variety of deeply held commitments to live together in mutual tolerance, free to figure out questions of individual morality and the good life for themselves.

Regarding Katrina Forrester’s “In the Shadow of Justice” (2019), a searching and brilliant history of how his ideas presumed a postwar consensus that was already fracturing at the time that “A Theory of Justice” was published, Chandler has little to say.

“Free and Equal” includes a detailed chapter on “Rawls and His Critics,” but mostly navigates around anything that might truly rattle the Rawlsian framework.

Perhaps Forrester wouldn’t be surprised by this move; as she puts it, “The capaciousness of liberal philosophy squeezed out possibilities for radical critique.”

Researchers call this effect “the liar’s dividend,” and politicians have already tried to cast off unfavorable clips as AI-generated: Last month, Donald Trump falsely claimed that an attack ad had used AI to make him look bad.

“Deepfake” could become the “fake news” of 2024, an infrequent but genuine phenomenon that gets co-opted as a means of discrediting the truth

Steve Bannon’s infamous assertion that the way to discredit the media is to “flood the zone with shit.”

AI is less likely to create new dynamics than to amplify existing ones. Presidential campaigns, with their bottomless coffers and sprawling staff, have long had the ability to target specific groups of voters with tailored messaging

They might have thousands of data points about who you are, obtained by gathering information from public records, social-media profiles, and commercial brokers

“It is now so cheap to engage in this mass personalization,” Laura Edelson, a computer-science professor at Northeastern University who studies misinformation and disinformation, told me. “It’s going to make this content easier to create, cheaper to create, and put more communities within the reach of it.”

That sheer ease could overwhelm democracies’ already-vulnerable election infrastructure. Local- and state-election workers have been under attack since 2020, and AI could make things worse.

Those officials have also expressed the worry, he said, that generative AI will turbocharge the harassment they face, by making the act of writing and sending hate mail virtually effortless. (The consequences may be particularly severe for women.)

past attacks—most notably the Russian hack of John Podesta’s email, in 2016—have wrought utter havoc. But now pretty much anyone—whatever language they speak and whatever their writing ability—can send out hundreds of phishing emails in fluent English prose. “The cybersecurity implications of AI for elections and electoral integrity probably aren’t getting nearly the focus that they should,”

Just last week, AI-generated audio surfaced of one Harlem politician criticizing another. New York City has perhaps the most robust local-news ecosystem of any city in America, but elsewhere, in communities without the media scrutiny and fact-checking apparatuses that exist at the national level, audio like this could cause greater chaos.

In countries that speak languages with less online text for LLMs to gobble up, AI tools may be less sophisticated. But those same countries are likely the ones where tech platforms will pay the least attention to the spread of deepfakes and other disinformation, Edelson told me. India, Russia, the U.S., the EU—this is where platforms will focus. “Everything else”—Namibia, Uzbekistan, Uruguay—“is going to be an afterthought,”

Most of us tend to fret about the potential fake video that deceives half of the nation, not about the flood of FOIA requests already burying election officials. If there is a cost to that way of thinking, the world may pay it this year at the polls.

Newsroom leaders, concerned that some Times journalists are compromising their neutrality and applying ideological purity tests to coverage decisions, are seeking to draw a line. 

Kahn noted that the organization has added a lot of digital-savvy workers who are skilled in areas like data analytics, design and product engineering but who weren’t trained in independent journalism. He also suggested that colleges aren’t preparing new hires to be tolerant of dissenting views

International editor Philip Pan later intervened, saying the WhatsApp thread—at its worst a “tense forum where the questions and comments can feel accusatory”—should be for sharing information, not for hosting debates, according to messages reviewed by the Journal. 

Coverage of the Israel-Hamas war has become particularly fraught at the Times, with some reporters saying the Times’s work is tilting in favor of Israel and others pushing back forcefully, say people familiar with the situation. That has led to dueling charges of bias and journalistic malpractice among reporters and editors, forcing management to referee disputes.

“Just like our readers at the moment, there are really really strong passions about that issue and not that much willingness to really explore the perspectives of people who are on the other side of that divide,” Kahn said, adding that it’s hard work for staffers “to put their commitment to the journalism often ahead of their own personal views.”

Last fall, Times staffers covering the war got into a heated dispute in a WhatsApp group chat over the publication’s reporting on Al-Shifa hospital in Gaza, which Israel alleged was a command-and-control center for Hamas.

While the Guild represents staffers across many major U.S. news outlets, its members also include employees from non-news advocacy organizations such as pro-Palestinian group Jewish Voice For Peace, Democratic Socialists of America and divisions of the ACLU. 

“Young adults who are coming up through the education system are less accustomed to this sort of open debate, this sort of robust exchange of views around issues they feel strongly about than may have been the case in the past,” he said, adding that the onus is on the Times to instill values like independence in its employees.

The publisher of the Times, 43-year-old A.G. Sulzberger, says readers’ trust is at risk, however. Some journalists, including at the Times, are criticizing journalistic traditions like impartiality, while embracing “a different model of journalism, one guided by personal perspective and animated by personal conviction,” Sulzberger wrote in a 12,000-word essay last year in Columbia Journalism Review. 

Despite such moves, NewsGuard, an organization that rates credibility of news sites, in February reduced the Times’s score from the maximum of 100 to 87.5, saying it doesn’t have a clear enough delineation between news and opinion.

Emboldened by their show of strength on Bennet, employees would flex their muscles again on multiple occasions, pushing to oust colleagues they felt had engaged in journalistic or workplace misconduct. 

One thing Powell noticed, he said, was that coverage that challenged popular political and cultural beliefs was being neglected. Powell’s work includes a story on MIT’s canceling of a lecture by an academic who had criticized affirmative action, and another examining whether the ACLU is more willing to defend the First Amendment rights of progressives than far-right groups.

Kahn, who succeeded Baquet as executive editor in June 2022, and Opinion Editor Kathleen Kingsbury said in a letter to staff that they wouldn’t tolerate participation by Times journalists in protests or attacks on colleagues.

Divisions have formed in the newsroom over the role of the union that represents Times staffers, the NewsGuild-CWA. Some staffers say it has inappropriately inserted itself into debates with management, including over coverage of the trans community and the war. 

The Times isn’t the only news organization where employees have become more vocal in complaints about coverage and workplace practices. War coverage has also fueled tensions at The Wall Street Journal, with some reporters in meetings and internal chat groups complaining that coverage is skewed—either favoring Israel or Palestinians.  

When Times staffers logged on to a union virtual meeting last fall to discuss whether to call for a cease-fire in Gaza, some attendees from other organizations had virtual backgrounds displaying Palestinian flags. The meeting, where a variety of members were given around two minutes to share their views on the matter, felt like the kind of rally the Times’ policy prohibits, according to attendees. 

In January, Sulzberger shared his thoughts on covering Trump during a visit to the Washington bureau. It was imperative to keep Trump coverage emotion-free, he told staffers, according to people who attended. He referenced the Times story, “Why a Second Trump Presidency May Be More Radical Than His First,” by Charlie Savage, Jonathan Swan and Maggie Haberman, as a good example of fact-based and fair coverage. 

The dourness of the mood contrasted sharply with just a year ago, when many of the same participants — intelligence chiefs and diplomats, oligarchs and analysts — thought Russia might be on the verge of strategic defeat in Ukraine. There was talk of how many months it might take to drive the Russians back to the borders that existed before their invasion on Feb. 24, 2022. Now that optimism appeared premature at best, faintly delusional at worst.

Nikolai Denkov, the prime minister of Bulgaria, argued that Europeans should draw three lessons from the cascade of troubles. The war in Ukraine was not just about gray zones between Europe and Russia, he argued, but “whether the democratic world we value can be beaten, and this is now well understood in Europe.”

“European defense was a possibility before, but now it’s a necessity,” said Claudio Graziano, a retired general from Italy and former chairman of the European Union Military Committee. But saying the right words is not the same as doing what they demand.

third, they needed to separate Ukraine’s urgent needs for ammunition and air defense from longer-term strategic goals.

Some attendees found the commitments made by the leaders who showed up uninspiring, said Nathalie Tocci, director of Italy’s Institute of International Affairs. “Kamala Harris empty, Scholz mushy, Zelensky tired,

“I feel underwhelmed and somewhat disappointed” by the debate here, said Steven E. Sokol, president of the American Council on Germany. “There was a lack of urgency and a lack of clarity about the path forward, and I did not see a strong show of European solidarity.

Second, European nations have realized that they must combine their forces in military, not just economic endeavors, to build up their own deterrence

now two-thirds of the alliance members have met the goal of spending 2 percent of their gross domestic product on defense — up from just a handful of nations 10 years ago. But a few acknowledged that goal is now badly outdated, and they talked immediately about the political barriers to spending more.

the prospect of less American commitment to NATO, as the United States turned to other challenges from China or in the Middle East, was concentrating minds.

the fundamental disconnect was still on display: When Europeans thought Russia would integrate into European institutions, they stopped planning and spending for the possibility they might be wrong. And when Russia’s attitude changed, they underreacted.

“This is 30 years of underinvestment coming home,” said François Heisbourg, a French defense analyst, who called them “les trente paresseuses” — the 30 lazy years of post Cold-War peace dividends, in contrast to the 30 glorious years that followed World War II.

What was important for Europeans to remember was that this hot war in Ukraine was close and could spread quickly, Ms. Kallas said. “So if you think that you are far away, you’re not far away. It can go very, very fast.”

Dmytro Kuleba, the foreign minister of embattled Ukraine, was blunter. “I think our friends and partners were too late in waking up their own defense industries,” he said. “And we will pay with our lives throughout 2024 to give your defense industries time to ramp up production.”

What is A.I. even for?

“A.I. slop”: often uncanny, frequently misleading material, now flooding web browsers and social-media platforms like spam in old inboxes. Years deep into national hysteria over the threat of internet misinformation pushed on us by bad actors, we’ve sleepwalked into a new internet in which meaningless, nonfactual slop is casually mass-produced and force-fed to us by A.I.

It has already helped drive down the cost and drive up the performance of next-gen batteries and solar photovoltaic cells, whose performance can also be improved, even after the panels have been manufactured and installed on your roof, by as much as 25 percent

while the internet was never perfectly trustworthy, one epoch-defining breakthrough of Google was that it got us pretty close. Now the company’s chief executive acknowledges that hallucinations are “inherent” to the technology it has celebrated as a kind of successor for ranked-order search results, which are now often found far below not just the A.I. summary but a whole stack of “sponsored” results as well.

Where not long ago we used to find the very best results for Google searches, we can now find instead potentially plagiarized and often inaccurate paragraph summaries of answers to our queries

Machine learning may help make our electricity grid as much as 40 percent more efficient at delivering power as it is today, when many of its routing decisions are made by individual humans on the basis of experience and intuition

This month, KoBold Metals announced the largest discovery of new copper deposits in a decade — a green-energy gold mine, so to speak, delivered with the help of its own proprietary A.I., which integrated information about subatomic particles detected underground with century-old mining reports and radar imagery to make predictions about where minerals critical for the green transition might be found.

.I. is designing new proteins, rapidly accelerating drug discovery and speeding up clinical trials testing new medicines and therapies.

perhaps that a more optimistic perspective can be drawn by analogy to what economists call the “environmental Kuznets curve,” which suggests that, as nations develop, they tend to first pollute a lot more and then, over time, as they grow richer, they ultimately pollute less.

Even in describing regular old pollution, this framework has its shortcomings, especially because it treats as automatic eventual progress that has always required tooth-and-nail fights against some very stubborn bad actors

A.I. is generating an awful lot of genuine pollution, too — both Google and Microsoft, which each pledged in 2019 to reach zero emissions by 2030, have instead expanded their carbon footprints by nearly 50 percent in the interim.

As the ideological glue that allows Belgians to cohabit has come unstuck, the traditional parties of government have found it difficult to retain public backing. Amid a wider fracturing of the vote, Flemish and Walloon voters are now lured by adventurers on right and left

Belgium serves as a stern reminder that there are few bulwarks against the trends that ail European nations. The country is no Italy or Netherlands, where the far right is already in government, and party democracy and its postwar prosperity survive only as faint memories.

Yet even with Belgium’s lower inequality rates, higher union membership and comparatively stronger party infrastructure, the march of the far right has also proved eerily unstoppable.

A closer look, however, would have revealed that individual journalists at BNN published lengthy stories as often as multiple times a minute, writing in generic prose familiar to anyone who has tinkered with the A.I. chatbot ChatGPT.

How easily the site and its mistakes entered the ecosystem for legitimate news highlights a growing concern: A.I.-generated content is upending, and often poisoning, the online information supply.

The websites, which seem to operate with little to no human supervision, often have generic names — such as iBusiness Day and Ireland Top News — that are modeled after actual news outlets. They crank out material in more than a dozen languages, much of which is not clearly disclosed as being artificially generated, but could easily be mistaken as being created by human writers.

Now, experts say, A.I. could turbocharge the threat, easily ripping off the work of journalists and enabling error-ridden counterfeits to circulate even more widely — as has already happened with travel guidebooks, celebrity biographies and obituaries.

The result is a machine-powered ouroboros that could squeeze out sustainable, trustworthy journalism. Even though A.I.-generated stories are often poorly constructed, they can still outrank their source material on search engines and social platforms, which often use A.I. to help position content. The artificially elevated stories can then divert advertising spending, which is increasingly assigned by automated auctions without human oversight.

NewsGuard, a company that monitors online misinformation, identified more than 800 websites that use A.I. to produce unreliable news content.

Low-paid freelancers and algorithms have churned out much of the faux-news content, prizing speed and volume over accuracy.

Former employees said they thought they were joining a legitimate news operation; one had mistaken it for BNN Bloomberg, a Canadian business news channel. BNN’s website insisted that “accuracy is nonnegotiable” and that “every piece of information underwent rigorous checks, ensuring our news remains an undeniable source of truth.”

this was not a traditional journalism outlet. While the journalists could occasionally report and write original articles, they were asked to primarily use a generative A.I. tool to compose stories, said Ms. Chakraborty and Hemin Bakir, a journalist based in Iraq who worked for BNN for almost a year. They said they had uploaded articles from other news outlets to the generative A.I. tool to create paraphrased versions for BNN to publish.

Mr. Chahal’s evangelism carried weight with his employees because of his wealth and seemingly impressive track record, they said. Born in India and raised in Northern California, Mr. Chahal made millions in the online advertising business in the early 2000s and wrote a how-to book about his rags-to-riches story that landed him an interview with Oprah Winfrey.

Mr. Chahal told Mr. Bakir to focus on checking stories that had a significant number of readers, such as those republished by MSN.com.Employees did not want their bylines on stories generated purely by A.I., but Mr. Chahal insisted on this. Soon, the tool randomly assigned their names to stories.

This crossed a line for some BNN employees, according to screenshots of WhatsApp conversations reviewed by The Times, in which they told Mr. Chahal that they were receiving complaints about stories they didn’t realize had been published under their names.

According to three journalists who worked at BNN and screenshots of WhatsApp conversations reviewed by The Times, Mr. Chahal regularly directed profanities at employees and called them idiots and morons. When employees said purely A.I.-generated news, such as the Fanning story, should be published under the generic “BNN Newsroom” byline, Mr. Chahal was dismissive.“When I do this, I won’t have a need for any of you,” he wrote on WhatsApp.Mr. Bakir replied to Mr. Chahal that assigning journalists’ bylines to A.I.-generated stories was putting their integrity and careers in “jeopardy.”

This was a strategy that Mr. Chahal favored, according to former BNN employees. He used his news service to exercise grudges, publishing slanted stories about a politician from San Francisco he disliked, Wikipedia after it published a negative entry about BNN Breaking and Elon Musk after accounts belonging to Mr. Chahal, his wife and his companies were suspended o

The increasing popularity of programmatic advertising — which uses algorithms to automatically place ads across the internet — allows A.I.-powered news sites to generate revenue by mass-producing low-quality clickbait content

Experts are nervous about how A.I.-fueled news could overwhelm accurate reporting with a deluge of junk content distorted by machine-powered repetition. A particular worry is that A.I. aggregators could chip away even further at the viability of local journalism, siphoning away its revenue and damaging its credibility by contaminating the information ecosystem.

That shame mangrove has been completely uprooted by Trump.

The reason people felt ashamed is that they felt fidelity to certain norms — so their cheeks would turn red when they knew they had fallen short

in the kind of normless world we have entered where societal, institutional and leadership norms are being eroded,” Seidman said to me, “no one has to feel shame anymore because no norm has been violated.”

People in high places doing shameful things is hardly new in American politics and business. What is new, Seidman argued, “is so many people doing it so conspicuously and with such impunity: ‘My words were perfect,’ ‘I’d do it again.’ That is what erodes norms — that and making everyone else feel like suckers for following them.”

Nothing is more corrosive to a vibrant democracy and healthy communities, added Seidman, than “when leaders with formal authority behave without moral authority.

Without leaders who, through their example and decisions, safeguard our norms and celebrate them and affirm them and reinforce them, the words on paper — the Bill of Rights, the Constitution or the Declaration of Independence — will never unite us.”

. Trump wants to destroy our social and legal mangroves and leave us in a broken ethical ecosystem, because he and people like him best thrive in a broken system.

He keeps pushing our system to its breaking point, flooding the zone with lies so that the people trust only him and the truth is only what he says it is. In nature, as in society, when you lose your mangroves, you get flooding with lots of mud.

Responsibility, especially among those who have taken oaths of office — another vital mangrove — has also experienced serious destruction.

It used to be that if you had the incredible privilege of serving as U.S. Supreme Court justice, in your wildest dreams you would never have an American flag hanging upside down

Your sense of responsibility to appear above partisan politics to uphold the integrity of the court’s rulings would not allow it.

Civil discourse and engaging with those with whom you disagree — instead of immediately calling for them to be fired — also used to be a mangrove.

when moral arousal manifests as moral outrage — and immediate demands for firings — “it can result in a vicious cycle of moral outrage being met with equal outrage, as opposed to a virtuous cycle of dialogue and the hard work of forging real understanding.”

In November 2022, the Heterodox Academy, a nonprofit advocacy group, surveyed 1,564 full-time college students ages 18 to 24. The group found that nearly three in five students (59 percent) hesitate to speak about controversial topics like religion, politics, race, sexual orientation and gender for fear of negative backlashes by classmates.

Locally owned small-town newspapers used to be a mangrove buffering the worst of our national politics. A healthy local newspaper is less likely to go too far to one extreme or another, because its owners and editors live in the community and they know that for their local ecosystem to thrive, they need to preserve and nurture healthy interdependencies

in 2023, the loss of local newspapers accelerated to an average of 2.5 per week, “leaving more than 200 counties as ‘news deserts’ and meaning that more than half of all U.S. counties now have limited access to reliable local news and information.”

As in nature, it leaves the local ecosystem with fewer healthy interdependencies, making it more vulnerable to invasive species and disease — or, in society, diseased ideas.

It’s not that the people in these communities have changed. It’s that if that’s what you are being fed, day in and day out, then you’re going to come to every conversation with a certain set of predispositions that are really hard to break through.”

we have gone from you’re not supposed to say “hell” on the radio to a nation that is now being permanently exposed to for-profit systems of political and psychological manipulation (and throw in Russia and China stoking the fires today as well), so people are not just divided, but being divided. Yes, keeping Americans morally outraged is big business at home now and war by other means by our geopolitical rivals.

More than ever, we are living in the “never-ending storm” that Seidman described to me back in 2016, in which moral distinctions, context and perspective — all the things that enable people and politicians to make good judgments — get blown away.

Blown away — that is exactly what happens to the plants, animals and people in an ecosystem that loses its mangroves.

a trend ailing America today: how much we’ve lost our moorings as a society.

Civil discourse and engaging with those with whom you disagree — instead of immediately calling for them to be fired — also used to be mangroves.

civility itself also used to be a mangrove.

“Why the hell not?” Drummond asks.“You’re not supposed to say ‘hell,’ either,” the announcer says.You are not supposed to say “hell,” either. What a quaint thought. That is a polite exclamation point in today’s social media.

Another vital mangrove is religious observance. It has been declining for decades:
