who got the future most right? For the truth is that dystopia is now, not in some future date.

Science fiction provides us with a large sample of imagined discontinuities that might not occur if we only looked backwards.

Fahrenheit 451 (published in 1953 but set in 1999) describes an illiberal America where books are banned and the job of firemen is to burn them. (Though the novel is sometimes interpreted as a critique of McCarthyism, Bradbury’s real message was that the preference of ordinary people for the vacuous entertainment of TV and the willingness of religious minorities to demand censorship together posed a creeping threat to the book as a form for serious content.)

In a remarkable letter written in October 1949, Aldous Huxley — who had been Orwell’s French teacher at Eton — warned him that he was capturing his own present rather than the likely future. ‘The philosophy of the ruling minority in Nineteen Eighty-Four,’ Huxley wrote, ‘is a sadism which has been carried to its logical conclusion… Whether in actual fact the policy of the boot-on-the-face can go on indefinitely seems doubtful. My own belief is that the ruling oligarchy will find less arduous and wasteful ways of governing and of satisfying its lust for power, and these ways will resemble those which I described in Brave New World’. Huxley’s Brave New World (1932) is a very different dystopia. Citizens submit to a caste system, conditioned to be content with physical pleasure. Self-medication (‘soma’), constant entertainment (the ‘feelies’), regular holidays and ubiquitous sexual titillation are the basis for mass compliance. Censorship and propaganda play a part, but overt coercion is rarely visible. The West today seems more Huxley than Orwell: a world more of corporate distraction than state brutality.

Yet none of these authors truly foresaw our networked world, which has combined the rising technological acceleration with a slackening of progress in other areas, such as nuclear energy, and a degeneration of governance. The real prophets are less known figures, like John Brunner, whose Stand on Zanzibar (1968) is set at a time — 2010 — when population pressure has caused social division and political extremism. Despite the threat of terrorism, US corporations are booming, thanks to a supercomputer. China is America’s new rival. Europe has united. Brunner envisaged affirmative action, genetic engineering, Viagra, Detroit’s collapse, satellite TV, in-flight video, gay marriage, laser printing, electric cars, the decriminalisation of marijuana and the decline of tobacco. There’s even a progressive president (albeit of the Africa state of Beninia, not America) named ‘Obomi’

With comparable prescience, William Gibson’s Neuromancer (1984) anticipates the world wide web and AI. Opening in the dystopian Japanese underworld of Chiba City, it imagines a global computer network in cyberspace called the ‘matrix’. Neal Stephenson’s Snow Crash (1992), which was especially popular among Facebook employees in the company’s early years, foresaw corporate overreach and virtual reality in an almost anarchic America. The state has withered away in California; everything has been privatised. Most people spend half their time in virtual reality, where their avatars have more fun than they themselves do in the real world. Meanwhile, flotillas of refugees approach via the Pacific. These cyberpunk Americas are much closer to the US in 2021 than the fascist dystopias of Lewis, Atwood or Roth.

Orwell and Huxley — have been outflanked when it comes to making sense of today’s totalitarian countries

Take China, which better resembles Yevgeny Zamyatin’s We: a book written in 1921, but suppressed by the Bolsheviks. It is set in a future ‘One State’ led by ‘the Benefactor’, where the ‘ciphers’ — who have numbers, not names, and wear standardised ‘unifs’ — are under constant surveillance. All apartments are made of glass, with curtains that can be drawn only when one is having state-licensed sex. Faced with insurrection, the omnipotent Benefactor orders the mass lobotomisation of ciphers, as the only way to preserve universal happiness is to abolish the imagination.

Chan Koonchung’s The Fat Years (2009) — which is banned in China. In this story, tap water is laced with drugs that render people docile, but at a cost. The month of February 2011 has been removed from public records and popular memory. This was when drastic emergency measures were introduced to stabilise the Chinese economy and assert China’s primacy in east Asia. Chan is one of a number of recent Chinese authors who have envisioned the decline of America, the corollary of China’s rise. The Fat Years is set in an imagined 2013, after a second western financial crisis makes China the world’s no. 1 economy.

Liu Cixin’s The Three-Body Problem (2006), a Chinese nanotechnology expert and a Beijing cop lead the global defence against an alien invasion that’s the fault of a misanthropic Chinese physicist.

It’s a puzzle. What do you get the country that has it all, and could have it all taken away?

Bush’s third big idea in the 2002 speech was to downgrade the importance of Afghanistan to the United States

The fourth core idea in the speech was a determination to regard terrorism as a tool of power.

The exhibition is one of several ways that Ukraine’s government is highlighting the devastation its people have endured even as new suffering is inflicted every day.

And Ukraine has taken the rare step of prosecuting Russian soldiers for war crimes just months after they were allegedly committed, greatly accelerating the normal judicial timetable.

“It is necessary to explain to our children what is happening in Ukraine now,” Mr. Spodinskiy said, as other visitors took photographs of the debris. “We cannot speak with our children as if nothing is happening,” he added, “because they clearly understand everything, and they see what happens in our country.”

“The history of our country is being created, and now this is an opportunity to get in touch with it,” said another visitor, Serhiy Pashchukov, a 31-year-old from Luhansk, which was occupied by Russia in 2014.

The sign, and everything else in the basement, was taken from a bomb shelter in a Kyiv suburb, Hostomel, the site of an airport that Russian soldiers tried to take in the first days of the war.

The rooms are dank and cold, but the most striking thing, many visitors said, was that it smells as if the people who sheltered with their belongings there — including onions, blankets, and toys — had just left.

“We had a similar basement in Bucha in a newly built apartment building,” said Evgeniya Skrypnyk, a 32-year-old from a suburb of Kyiv where Russian soldiers killed and terrorized civilians.

The one historical inaccuracy in the shelter was the absence of the five buckets that stood in the hallway where the people who lived underground for more than a month relieved themselves.

Remembrance of World War II has become more complex since the war started. In Russia, the Kremlin has sought to glorify the Soviet victory — to which millions of Ukrainians contributed — as a source of national pride. But it has also called upon memories of that war to justify and build support for the invasion of Ukraine, with Mr. Putin seeking to falsely portray Ukrainian leaders as “Nazis.”

Mr. Savchuk said that in light of the current war, people were talking about a “complete reconstruction” of the museum complex, whose architecture is intended to awe visitors with the memory of the Soviet victory in World War II, to de-emphasize the fight against Nazi Germany.

“This war changed everything,” he said. “A museum is not only an exhibition, it is a territory, it is its monuments, it is a place of memory. We are thinking about changing not only the ideology, but also the architecture, the emphasis.”

According to a U.S. intelligence assessment, a group of investors led by one of Russia’s richest men, Gennady Timchenko, who has been under sanctions since 2014, provided the money to buy three ships: the Scheherazade, the Crescent and the Amadea, whose construction at a German shipyard was overseen by Imperial Yachts. Their combined cost of as much as $1.6 billion could have bought six new frigates for the Russian navy.

“Imperial Yachts conducts all its business in full compliance with laws and regulations in all jurisdictions in which we operate,” the company added. “We are not involved in our clients’ financial affairs.”

But Treasury officials disputed that contention in their announcement. U.S. and international authorities have moved to seize the three yachts connected to Mr. Kochman and his company.

In an interview Tuesday, before the new sanctions were announced, Elizabeth Rosenberg, the assistant secretary for terrorist financing and financial crimes at the Treasury Department, said that international cooperation to go after Russian oligarchs and their assets was increasing.

“It feels like we’re experiencing a sea change right now,” Ms. Rosenberg said. “It’s a huge leap forward on international cooperation for hunting assets, for freezing them and for pursuing law enforcement investigations and activity, including seizure activities.”

Treasury officials say taking action against oligarchs and the companies that help them spend their wealth will ultimately hurt the Russian government’s ability to wage war against Ukraine.

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.

there’s little reason to enserf or enslave a worker (not quite the same thing, but let’s leave that aside) if labor is abundant and land is scarce, so that the amount that worker could earn if he ran away barely exceeds the cost of subsistence.

But if land becomes abundant and labor scarce, the ruling class will want to pin workers in place, so they can forcibly extract the difference between the value of what workers can produce — strictly speaking, their marginal product — and the cost of keeping them alive.

Yet serfdom wasn’t reimposed, for reasons that aren’t entirely clear. One thought, however, is that holding people captive in order to steal the fruits of their labor isn’t easy.

In fact, the real historical puzzle is why high wages didn’t always lead to widespread slavery or serfdom

serfdom in the West had more or less withered away by around 1300, because Western Europe was overpopulated given the technologies of the time, which in turn meant that landowners didn’t need to worry that their tenants and workers would leave in search of lower rents or higher wages.

But the Black Death caused populations to crash and wages to soar. In fact, for a while, real wages in Britain reached a level they wouldn’t regain until around 1870:

Labor was scarce in pre-Civil War America, so free workers earned high wages by European standards. Here are some estimates of real wages in several countries as a percentage of U.S. levels on the eve of the Civil War:

Indeed, slaveholders and their defenders lashed out at anyone who even suggested that slavery was a bad thing. As Abraham Lincoln said in his Cooper Union address, the slave interest in effect demanded that Northerners “cease to call slavery wrong, and join them in calling it right.”

Notice that Australia — another land-abundant, labor-scarce nation — more or less matched America; elsewhere, workers earned much less.

Landowners, of course, didn’t want to pay high wages. In the early days of colonial settlement, many Europeans came as indentured servants — in effect, temporary serfs

landowners quickly turned to African slaves, who offered two advantages to their exploiters: Because they looked different from white settlers, they found it hard to escape, and they received less sympathy from poor whites who might otherwise have realized that they had many interests in common. Of course, white southerners also saw slaves as property, not people, and so the value of slaves factored into the balance sheet of this greed-driven system.

again, the dynamic was one in which greedy slaveholders used and perpetuated racism to sustain their reign of exploitation and terror.

Because U.S. slavery was race-based, however, there was a limited supply of slaves, and it turned out that slaves made more for their masters in Southern agriculture than in other occupations or places

Black people in the North were sold down the river to Southern planters who were willing to pay more for them, so slavery became an institution peculiar to one part of the country.

As such, slaves became a hugely important financial asset to their owners. Estimates of the market value of slaves before the Civil War vary widely, but they were clearly worth much more than the land they cultivated, and may well have accounted for the majority of Southern wealth.

Inevitably, slaveholders became staunch defenders of the system underlying their wealth

Hence the rise of serfdom as Russia expanded east, and the rise of slavery as Europe colonized the New World.

But Northerners wouldn’t do that. There were relatively few Americans pushing for national abolition, but Northern states, one by one, abolished slavery in their own territories

This wasn’t as noble an act as it might have been if they had been confiscating slaveholders’ property, rather than in effect waiting until the slaves had been sold. Still, it’s to voters’ credit that they did find slavery repugnant.

And this posed a problem for the South

Anyone who believes or pretends to believe that the Civil War was about states’ rights should read Ulysses S. Grant’s memoirs, which point out that the truth was almost the opposite. In his conclusion, Grant noted that maintaining slavery was difficult when much of the nation consisted of free states, so the slave states in effect demanded control over free-state policies.

This should sound familiar. Since the Supreme Court overturned Roe v. Wade, states that have banned abortion have grown increasingly frantic over the ability of women to travel to states where abortion rights remain; it’s obvious that the right will eventually impose a national abortion ban if it can.

For a long time, the South actually did manage to exercise that kind of national control. But industrialization gradually shifted the balance of power within the United States away from the South to the North:

So did immigration, with very few immigrants moving to slave states.And the war happened because the increasingly empowered people of the North, as Grant wrote, “were not willing to play the role of police for the South” in protecting slavery.

So yes, the Civil War was about slavery — an institution that existed solely to enrich some men by depriving others of their freedom

And there’s no excuse for anyone who pretends that there was anything noble or even defensible about the South’s cause: The Civil War was fought to defend an utterly vile institution.

there’s a deeper reason for my harsh judgment, which is that I’m fully committed to the liberal project of domesticating and taming the most intense political passions, ultimately channeling them into representative political institutions, where they are forced to reach accommodation and compromise with contrary views held by other members of the polity.

The love of justice can be noble, but it can also be incredibly destructive.

(This is hard to see if you conveniently associate such love exclusively with positions staked out by your ideological or partisan allies. In reality, the political ambitions of one’s opponents are often fueled by their own contrary convictions about justice and its demands.

My liberal commitments therefore make me maximally suspicious of most examples of “street politics,” especially forms of it in which the activists risk very little and primarily appear to be engaging in a spiritually fulfilling form of socializing with likeminded peers.

But Bushnell’s act of self-immolation belongs in a different category altogether—one distinct from just about every other form of protest,

Bushnell could have written an op-ed. He could have joined, organized, or led a march and delivered a speech. He could have built up a loud social-media presence and used it to accuse the United States of complicity in genocide and publicize the accusation. He could have leveraged his position in the Air Force to draw added attention to his dissent from Biden administration policy in the Middle East. He could even have embraced terrorism and sought to gain entry to the Israeli embassy with a weapon or explosive

But Bushnell didn’t do any of these things. Instead, a few hours before his act of protest, he posted the following message on Facebook:

Many of us like to ask ourselves, “What would I do if I was alive during slavery? Or the Jim Crow South? Or apartheid? What would I do if my country was committing genocide?”The answer is, you’re doing it. Right now.

I will no longer be complicit in genocide…. I am about to engage in an extreme act of protest. But compared to what people have been experiencing in Palestine at the hands of their colonizers, it’s not extreme at all. This is what our ruling class has decided will be normal.

And then, like a small number of other intensely committed individuals down through the decades, he doused himself in a flammable liquid and set himself ablaze, opting to sacrifice his own life in a public act of excruciating self-torture, without doing anything at all to harm anyone but himself, in order to draw attention to what he considered an ongoing, intolerable injustice.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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