Sutskever helped create AI software at the University of Toronto, called AlexNet, which classified objects in photographs with more accuracy than any previous software had achieved, laying much of the foundation for the field of computer vision and deep learning.

He recently shared a radically different vision for how AI might evolve in the near term. Within five to 10 years, there could be “data centers that are much smarter than people,” Sutskever said on a recent episode of the AI podcast “No Priors.” Not just in terms of memory or knowledge, but with a deeper insight and ability to learn faster than humans.

At the bare minimum, Sutskever added, it’s important to work on controlling superintelligence today. “Imprinting onto them a strong desire to be nice and kind to people — because those data centers,” he said, “they will be really quite powerful.”

OpenAI has a unique governing structure, which it adopted in 2019. It created a for-profit subsidiary that allowed investors a return on the money they invested into OpenAI, but capped how much they could get back, with the rest flowing back into the company’s nonprofit. The company’s structure also allows OpenAI’s nonprofit board to govern the activities of the for-profit entity, including the power to fire its chief executive.

As news of the circumstances around Altman’s ouster began to come out, Silicon Valley circles have turned to anger at OpenAI’s board.

“What happened at OpenAI today is a board coup that we have not seen the likes of since 1985 when the then-Apple board pushed out Steve Jobs,” Ron Conway, a longtime venture capitalist who was one of the attendees at OpenAI’s developer conference, said on X. “It is shocking, it is irresponsible, and it does not do right by Sam and Greg or all the builders in OpenAI.”

This week the first of 21 funerals are scheduled in Uvalde.Residents of the shattered town urged Biden to "do something" about gun violence as he visited on Sunday to meet with families and first responders.

Biden has backed multiple actions, including a renewed assault weapons ban and universal background checks. But the president, whose fellow Democrats only narrowly control Congress, has cited the limits of executive action and urged lawmakers to act.Democrats need 10 Republican senators' support to pass any legislation.

While school shootings are shocking, U.S. gun violence occurs regularly. Over the weekend, six people were shot and wounded in Chattanooga, Tennessee, while at least one person died and several were injured amid gunfire at an outdoor festival in Oklahoma City, local media reported.

With Mahinda Rajapaksa, the president, then at the peak of his powers, he did what many nationalist strongmen do: erect tributes to himself.

That’s now all gone. Sri Lanka is an international basket case whose foreign reserves — which once stood at over $6 billion under the Rajapaksas — have dwindled to almost nothing.

The collapse is partly a result of the loss of tourism during the pandemic, a problem made worse as war has kept away many of the Russians and Ukrainians who used to visit in large numbers. But the family’s economic mismanagement and denial of festering problems have also contributed mightily.

With food prices rising, electricity often cut and lifesaving medicines scarce, protesters have pushed Mr. Rajapaksa, 76, out of his latest position — prime minister — and are demanding that his brother Gotabaya, 72, give up the presidency.

Just outside the private residence of Mr. Rajapaksa, the Carlton House, they tied ropes to a gold-colored statue of his father, D.A. Rajapaksa. When they couldn’t drag it down, they dug under its feet until it collapsed. And around the corner from the family’s sprawling ancestral estate, they torched the museum memorializing the resting place of the patriarch and his wife.

“Whatever the politics, they shouldn’t have done this to their parents’ resting place.”

During her grocery trips, she can buy only half of what she did in the past.

Before the economy crashed, she would sell 30 to 40 pots a day. That number has since dropped to about 20, as people have saved for other necessities. Most days in recent weeks, she has come back with half of her stack of 15 unsold.

She was clear about who was to blame: the Rajapaksas.

“If you are investing in debt, you should really be looking at return — and quick return. You can’t do all your long-term, hard infrastructure projects on debt,” said Eran Wickramaratne, a former banker turned state minister of finance. “We completely overleveraged ourselves, and the returns are not there.”

With their power consolidated, they announced broad tax cuts — rapidly undoing the work of aligning Sri Lanka’s spending more with its means — and made a disastrous decision to ban chemical fertilizers in hopes of turning the country toward organic farming.

At the airport, which for a time was used to store grain, the only outsiders are the crews of occasional cargo flights, or groups of curious villagers on tours to see the complex. The cricket stadium, where the scoreboard clock is stuck in some afternoon past, was at one point rented out as a wedding venue to produce some revenue. It has a capacity of 35,000, more than the town of Hambantota’s entire population, 25,000.

“But these megaprojects were meaningless,” he said. “This region still has elephants crossing the roads, and people are still cultivating paddy as a livelihood. So these projects were unnecessary.”

“They did a lot — they won the war, they built roads,” Ms. Niroshani said.

But what about economic hardship, Ms. Wijeyawickrama asked.

“In a few days it may be that we have nothing to eat.”

Irma Garcia, 46: Garcia spent 23 years at Robb Elementary, five of them as Mireles’s co-teacher. She liked to sing along to classic rock tunes and help her nephew, a college student, with his homework. Garcia was known as a steadfast optimist. She enjoyed barbecuing with her husband of 24 years, Joe; he died yesterday, of a heart attack.

he Bureau of Alcohol, Tobacco, Firearms and Explosives is also assisting on scene, the ATF Dallas Field Division said on Twitter. "What happened today in Tulsa is a senseless act of violence and hatred," Oklahoma Gov. Kevin Stitt wrote on Twitter. "I am grateful for the quick and brave actions of the Tulsa Police Department and other first responders who did their best to contain a terrible situation."

Debra Proctor was in another building on the hospital campus for a doctor's appointment when she heard police sirens ringing out. When she stepped outside, first responders were lined up everywhere, she told CNN. Proctor, who has been a registered nurse for more than four decades, said it was a "shocking" scene."Police were everywhere in the parking lot, up and down the surrounding blocks," Proctor said. "They were still arriving when I was leaving."Kalen Davis, a lifelong Tulsa resident, was waiting in traffic around 5 p.m. local time when she saw multiple police cars responding to the scene.

Police later received information that the shooter may have left a bomb in a residence in Muskogee, Oklahoma, Muskogee police said Wednesday night. The home was searched by a bomb squad and no explosives were found, CBS Tulsa affiliate KOTV reported, citing Muskogee Police. Surrounding homes were either evacuated or residents were told to shelter in place.Muskogee is located about 50 miles southeast of Tulsa.Tulsa police asked family and friends of the victims and survivors to go to Memorial High School, a block from the hospital campus, to wait to learn the fate of the people at the shooting scene, KOTV said.  

Hodges said she was in lockdown for just under two hours.Another employee wondered out loud, "What's going on with the world these days?" A witness observed, "I mean, it's a doctor's office, like, you can't go nowhere no more without something happening. I's just crazy."

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.

I have some fond memories of my trips to the pre-collapse Soviet Union (I made four from 1983 to 1991). It was a weird and fascinating place. But it was also every inch the “evil empire” that President Ronald Reagan described, a place of fear and daily low-grade paranoia where any form of social attachment, whether religion or simple hobbies, was discouraged if it fell outside the control of the party-state.

the idea that anyone in Moscow would be stupid or deranged enough to want to reassemble the Soviet Union seemed to me a laughable fantasy. Even Putin himself—at least in public—often dismissed the idea.

I was wrong. I underestimated the power of Soviet imperial nostalgia. And so today, I grieve.

It was never designed, however, to function with one of its permanent members running amok as a nuclear-armed rogue state, and so today the front line of freedom is in Ukraine

I have lived through two eras, one an age of undeclared war between two ideological foes that threatened instant destruction, the next a time of increasing freedom and global integration. This second world was full of chaos, but it was also grounded in hope

I was convinced that everything I knew was more than likely destined to end in flames. Peace seemed impossible; war felt imminent.

Now I live in a new era, one in which the world order created in 1945 is collapsing.

The United Nations, as I once wrote, is a squalid and dysfunctional organization, but it is still one of the greatest achievements of humanity.

The Soviet collapse did not mean the end of war or of dictatorships, but after 1991, time seemed to be on the side of peace and democracy, if only we could summon the will and find the leadership to build on our heroic triumphs over Nazism and Communism.

But democracy is under attack everywhere, including here in the United States

I will celebrate the courage of Ukraine, the wisdom of NATO, and the steadfastness of the world’s democracies

But I also hear the quiet rustling of a shroud that is settling over the dreams—and perhaps, illusions—of a better world that for a moment seemed only inches from our grasp.

I do not know how this third era of my life will end, or if I will be alive to see it end. All I know is that I feel now as I did that night in Red Square, when I knew that democracy was in the fight of its life, that we might be facing a catastrophe, and that we must never waver.

I think that the age of the New Democrats, which was a very successful political project for the Democratic Party, has come to an end. The assumption of that politics, which began in earnest in the late 1980s and early 1990s, was that the Cold War had been settled, that democracy had prevailed, that the West was ascendant. But with China’s decision to take the route that they’ve gone on, with Russia now having waged this intense insurgency against the West, the assumption that that system is going to prevail in the world is now under question.

Rosenberg: Any honest assessment of the New Democrat project has to view it as wildly successful, because when I went to work for Clinton in 1992, Democrats had lost five out of the six previous presidential elections. And the central project of the New Democrats was to make the Democratic Party competitive at the presidential level again. Since then, we’ve won more votes in seven of eight presidential elections

I think that it’s birthing now for the United States a different era of politics, where we must be focused on two fundamental, existential questions. Can democracy prevail given the way that it’s being attacked from all sides? And can we prevent climate change from overwhelming the world that we know?

I want to try to write a book and to take the perspective of having been part of the beginning of the last big shift in American politics, the emergence of the New Democrats, and start imagining what’s going to come next for the center left in the United States and around the world.

Simon Rosenberg:

We’ve also seen three Democratic presidents that have served [since then]—Clinton, Barack Obama, and Joe Biden have also made the country materially better during their presidencies.

what’s the main lesson you take from his emergence?

Rosenberg: Yeah, it’s obviously disappointing. The emergence of what I call “Greater MAGA” has been a dark period in our history.

You have to recognize just how central to that is this narrative of the white tribe rallying around itself, and the sense of grievance, the sense of loss, the sense of decline. That’s what MAGA is. That’s all it is

We know from history, we know from other countries, when countries go into sectarian or tribal warfare, it can destroy a country, pull it apart. And Trump has created a domestic argument here that could potentially destroy the U.S. Look at Marjorie Taylor Greene this week—advocating for the country to split into two, red and blue.

Part of the reason I’m taking a step back from NDN is that I don’t think that we have yet figured out how to talk to the American people about the nature of the conflict we’re in right now, with rising authoritarianism around the world, the weakening of democratic institutions here and in other places.

My hope is that because Biden won’t be able to legislate very much for the next two years, he’ll spend his time talking to the American people and the West about the necessity of winning this conflict.

Rosenberg: The threat is still here. Look, I think [Florida Governor] Ron DeSantis is even more MAGA than Trump. This idea that in 2024, Republicans are going to end up with a moderate, center-right candidate and distance themselves from the insanity of the Trump years, that’s just fantasy talk.

DeSantis has decided to double down on extremism and on MAGA. We will learn in the next year and a half about how it all plays out. But I think he misread the room; he’s misread the moment in history. He needed to become an anti-Trump; instead, he became more Trump than Trump

In this last election, there were really two elections. There was a bluer election inside the battlegrounds, and there was a redder election outside the battlegrounds. We actually gained ground in seven battleground states: Arizona, Colorado, Georgia, Michigan, Minnesota, New Hampshire, and Pennsylvania. It’s an extraordinary achievement given high inflation, a low Biden approval rating, traditional midterm dynamics. My view is, that happened because the fear of MAGA has created a supercharged grass roots; our candidates are raising unprecedented amounts of money; we have more labor to work in these races than we’ve ever had before. And where we have these muscular campaigns, we were able to control the information environment. And also push turnout up through the roof.

But outside the battlegrounds, we fell back in New York and California, and in Florida and Texas, the four biggest states in the country. And the admonition to us is that we are still not competitive enough in the national daily discourse;

Republicans, because of this incredible noise machine that they built, are still far louder than we are. Democrats have to become obsessive about being more competitive in the daily political discourse in the country.

We have to build more media institutions. Republicans use ideological media to advance their politics in a way that we’ve never done. And we’re going to have to match that to some degree.

The second piece is that average Democratic activists have to recognize that they need to become information warriors daily

I think the way we have to think of the war room now, it’s 4 million proud patriots getting up every day, spending a little bit of their day putting good information into our daily discourse to try to crowd out the poisonous information and right-wing propaganda. There’s a lot that average citizens can do in this.

The key is to defeat MAGA in such a definitive and declarative way that Republicans move on to a different kind of politics and become something more like a traditional center-right political party.

We must stick together as a party because what will cause far-right political parties to succeed is when the prodemocracy coalition splits, and we can’t allow that to happen. As much as sometimes we want to have interfamily battles, those are self-indulgent at this point.

I don’t think that this emerging criticism is entirely wrong, but it’s only half right. The goal should be to expand, not to reposition. There are four areas that I think we have to bear down on in the next two years for a potential Democratic expansion: young voters, Latinos, Never-MAGA or -Trumpers, and young women, post-Dobbs.

The No. 1 job is we just need more young people voting, period. It’s more registration, more communications, targeting them more in our campaigns. In the Democratic Party, young people are still at the kids’ table; they have to become the center of our politics now.

I think that we’re favored in the presidential election. For us to win next year, the economy has to be good. And we have to look like we’ve been successful in Ukraine. Those two things are going to be paramount in him being able to say, “I’ve been a good president, and I may be a little bit old, but I still got 90 miles an hour on my fastball, and I’m able to get the job done right versus they’re still a little bit too crazy.”

What the Republicans should be worried about is we’ve had three consecutive elections where the battleground states have rejected MAGA. And so, if the Republicans present themselves as MAGA again, which looks almost inevitable, it’s going to be hard for them to win a presidential election in 2024 given that the battleground has muscle memory about MAGA and has voted now three times against it.

The western world kept a buzz going for twelve years, and that’s an accomplishment. It must also be said that the 1990s weren’t squandered, because even in the dark years they were fun. They weren’t complicated.

the 1990s make great nostalgia bait: simpler politics, plus great music, plus cool fashion cues. And maybe we can create another halcyon bubble again one day!

The generation that came of age in the 1990s, now well into middle age, have a lot of happy memories of a sort that may never be possible to have again. At the moment any possibility of collective joy seems about as realistic as a Miss America contestant trying to wish world peace into existence

n the 1990s we still had the future, a place that you could travel to, that would be cool when you got there, like Australia or the South Pole. Right now we merely have a future, and a murky one at that, and it’s probably more like Kenosha, Wisconsin than Sydney.

I remember doing a book tour and ending up on a local AM radio station’s podium at the grand opening of Mall of America in Bloomington, Minnesota on 11 August 1992. It was full of Americans in alpha consumption mode, eating ice cream, faces beaming, walking around in unselfconscious bliss. The local radio jock said to me, “You must think all of this is pretty silly”. He motioned towards the crowd and then to a rollercoaster directly beside us that came screeching at our heads every 95 seconds.

But I said, “No. In a century people are going to look back on right now as a sort of magic era, a charmed time of peace and prosperity and freedom from fear, as something that can never happen again, no matter how much they wish it would”.

On Thursday, rescuers said they had found engine components, part of a wing and other “important debris” as they searched the mountainside in a rural part of the Guangxi region for a fourth day.

Mr. Zhang, who was born in 1963, was one of China’s most experienced pilots,

A day earlier, the workers had found a black box, believed to be the cockpit voice recorder, which could provide investigators with crucial details. Officials said it was damaged but that its memory unit was relatively intact. The plane’s second black box, which records flight data, has yet to be recovered.

Their past performance was “very good,” Sun Shiying, the chairman of China Eastern Airlines’ Yunnan branch, said on Wednesday. When reached by phone, an airline representative declined to answer further questions about the crew.

At the main crash site, a state broadcaster showed the workers digging with shovels around a large piece of wreckage that the reporter described as a wing, which bore part of the China Eastern logo and was perched on a steep, barren slope fringed by dense thickets of now-flattened bamboo. Heavy rains had left the roads slick and inundated the earth with muddy pools.

Over his career as a commercial pilot with China Yunnan, which later merged with China Eastern, Mr. Zhang flew four different models of aircraft and accumulated 31,769 hours of flight experience.

The airline commonly paired young pilots with older pilots, and Mr. Zhang had mentored more than 100, CAAC News said. Mr. Yang was one of them.

Experts said that investigating the crash, which involved a sudden dive from cruising altitude in good weather, would require a close look at both the aircraft and the pilots, including the possibility that the plane was deliberately brought down. But they stressed that the cause was far from determined.

“Certainly an intentional downing is always a part of any investigation, and especially with this particular flight profile,” said Hassan Shahidi, chief executive of the Flight Safety Foundation, a nonprofit organization created after World War II to promote aviation safety. But he cautioned that it was “premature to jump onto any possibilities.”

“If the captain were intending to commit suicide, they’d have to overcome the other flight crew members,” Mr. Marks said.

he started receiving death threats. People said they wished he and his family had been killed by drug lords, told him that “sooner or later your punishment will arrive” and proposed that he be nailed into a coffin or run over by a cement roller.

Mr. Moreno, who grew up in Colombia, began working as a researcher in a computer science and robotics lab in Paris in 1983; the career that followed involved creating a start-up, meeting the Dalai Lama and being named a knight of the Légion d’Honneur. His work has won several awards and spanned many fields — automotive, medical, nuclear, military, even home goods.

Many of the recent threats have been directed at scientists studying Covid-19. In a survey of 321 such scientists who had given media interviews, the journal Nature found that 22 percent had received threats of physical or sexual violence and 15 percent had received death threats

Last year, an Austrian doctor who was a vocal supporter of vaccines and a repeated target of threats died by suicide.

increasingly, even professors and researchers without much of a public persona have faced intimidation from extremists and conspiracy theorists.

Around 2010, he started thinking about how technology could help create sustainable cities. Eventually, he refined his ideas about “human smart cities” and “living cities” into his 2016 proposal for 15-minute cities.

The idea owes much to its many predecessors: “neighborhood units” and “garden cities” in the early 1900s, the community-focused urban planning pioneered by the activist Jane Jacobs in the 1960s, even support for “new urbanism” and walkable cities in the 1990s. So-called low-traffic neighborhoods, or LTNs, have been set up in several British cities over the past few decades.

Critics of 15-minute cities have been outspoken, arguing that a concept developed in Europe may not translate well to highly segregated American cities. A Harvard economist wrote in a blog post for the London School of Economics and Political Science in 2021 that the concept was a “dead end” that would exacerbate “enormous inequalities in cities” by subdividing without connecting them.

Jordan Peterson, a Canadian psychologist with four million Twitter followers, suggested that 15-minute cities were “perhaps the worst imaginable perversion” of the idea of walkable neighborhoods. He linked to a post about the “Great Reset,” an economic recovery plan proposed by the World Economic Forum that has spawned hordes of rumors about a pandemic-fueled plot to destroy capitalism.

A member of Britain’s Parliament said that 15-minute cities were “an international socialist concept” that would “cost us our personal freedoms.” QAnon supporters said the derailment of a train carrying hazardous chemicals in Ohio was an intentional move meant to push rural residents into 15-minute cities.

“Conspiracy-mongers have built a complete story: climate denialism, Covid-19, anti-vax, 5G controlling the brains of citizens, and the 15-minute city for introducing a perimeter for day-to-day life,” Mr. Moreno said. “This storytelling is totally insane, totally irrational for us, but it makes sense for them.”

The multipronged conspiracy theory quickly became “turbocharged” after the Oxford protest, said Jennie King, head of climate research and policy at the Institute for Strategic Dialogue, a think tank that studies online platforms.

“You have this snowball effect of a policy, which in principle was only going to affect a small urban population, getting extrapolated and becoming this crucible where far-right groups, industry-sponsored lobbying groups, conspiracist movements, anti-lockdown groups and more saw an opportunity to insert their worldview into the mainstream and to piggyback on the news cycle,”

The vitriol currently directed at Mr. Moreno and researchers like him mirrors “the broader erosion of trust in experts and institutions,”

Modern conspiracy theorists and extremists turn the people they disagree with into scapegoats for a vast array of societal ills, blaming them personally for causing the high cost of living or various health crises and creating an “us-versus-them” environment, she said.

“I am not a politician, I am not a candidate for anything — as a researcher, my duty is to explore and deepen my ideas with scientific methodology,” he said. “It is totally unbelievable that we could receive a death threat just for working as scientists.”

Mr. Khamenei’s ruling philosophy has been shaped and reinforced by three notable authoritarian collapses: The 1979 fall of Iran’s monarchy, the 1991 dissolution of the Soviet Union and the Arab uprisings of 2011. His takeaway from each of these events has been to never compromise under pressure and never compromise on principles.

The Iranian regime’s repressive capacity — at least on paper — remains formidable. Ayatollah Khamenei is commander in chief of 190,000 armed members of the Islamic Revolutionary Guard Corps, who oversee tens of thousands of Basij militants tasked with instilling public fear and morality.

Iran’s nonideological conscription army, whose active forces are an estimated 350,000, is unlikely to take part in mass repression

Until now, the political and financial interests of Ayatollah Khamenei and the Revolutionary Guards have been intertwined. But persistent protests and chants of “Death to Khamenei” might change that

The sociologist Charles Kurzman wrote in his seminal book, “The Unthinkable Revolution in Iran,” that the paradox of revolutionary movements is that they are not viable until they attract a critical mass of supporters but that to attract a critical mass of supporters, they must be perceived as viable.

If the organizing principle that united Iran’s disparate opposition forces in 1979 was anti-imperialism, the organizing principles of today’s socioeconomically and ethnically diverse movement are pluralism and patriotism.

The faces of this movement are not ideologues or intellectuals but athletes, musicians and ordinary people, especially women and ethnic minorities, who have shown uncommon courage. Their slogans are patriotic and progressive — “We will not leave Iran, we will reclaim Iran,” and “Women, life, freedom.”

The demands of the current movement are brilliantly distilled in Shervin Hajipour’s song “Baraye,” or “For,” which has become the anthem of the protests and articulates a “yearning for a normal life” rather than the “forced paradise” of a religious police state.

Abbas Amanat, a historian of Iran, observed that one of the keys to Iran’s civilizational longevity, which dates to the Persian Empire of 2,500 years ago, is the power of its culture to co-opt its military invaders. “For nearly two millenniums, Persian political culture and, in a broader sense, a repository of Persian civilizational tools successfully managed to convert Turkic, Arab and Mongolian conquerors,” he told me. “Persian language, myth, historical memories and timekeeping endured. Iranians persuaded invaders to appreciate a Persian high culture of poetry, food, painting, wine, music, festivals and etiquette.”

When Ayatollah Khomeini acquired power in 1979, he led a cultural revolution that sought to replace Iranian patriotism with a purely Islamic identity. Ayatollah Khamenei continues that tradition, but he is one of the few remaining true believers. While the Islamic Republic sought to subdue Iranian culture, it is Iranian culture and patriotism that are threatening to undo the Islamic Republic.

Four decades of the Islamic Republic’s hard power will ultimately be defeated by two millenniums of Iranian cultural soft power. The question is no longer about whether this will happen but when.

Our minds are asymmetric judges, applying harsher moral judgment to present and future transgressions than past ones. It is as if the past becomes blurry. We even tend to blame the victim of a past event more than we blame the victim of a future one.

Third, our minds struggle with the negative emotions that our country’s complicated past gives rise to.

Research shows we are drawn to a sentimental form of history—nostalgia—which leads us to feel more loved, more protected, and even more competent in our ability to start and maintain relationships.

Nostalgia is often tied to the identities that we care most deeply about, such as our family or national identity. And, nostalgia is big business—in fashion, advertising, music and tourism, among other things.

Second, our minds tend to overplay sweet memories that favor our ancestors from the past.

When we learn about historical atrocities, particularly ones that expose our limited knowledge, contradict the narratives we believe, or implicate our own ancestors, we might experience shame, guilt, disbelief or anger. In response, we have a natural desire to pull away from the new knowledge and perhaps even refute it, rather than try to better understand it.

Fourth, our minds want to pick either a beautiful or a brutal narrative.

Contradictions, though, pocket our history, beginning with forefathers who had an extraordinary vision of equality, and simultaneously enslaved other humans

Our minds resist the paradoxes that characterize our country’s past. It’s so much less psychologically painful to pick one path than to grapple with both ideas at the same time.

Tools to useWhile the past is in the past, we can address the psychological challenge, however formidable, in the present. We have tools that will help, and I anticipate (and hope) that our debates will take on more psychological nuance as we shift from arguments over whether to explore our history more fully to how to do it.

For example, research shows the importance of returning to our values again and again as a way of inoculating us from setbacks

The daily arguments over curfews or messy rooms or study habits can cause us to shut down (“Do whatever you want”) or double down (“I’m your parent and you’ll do what I say”). Instead, it’s helpful to remind ourselves and our children that a parent has three jobs—to teach them, to protect them and to love them. Just doing that can ground us, and enable us to stay engaged, resilient and calm.

Similarly, when we confront a historical event, it can help to reflect on questions like, “Which American ideals do you most value?” and, “How do you hope others see your country?

You can even write out your responses, share them with others, and reread what you have written. Think of it as a values booster shot

Say, for instance, that you deeply value freedom. Keeping this value in your thoughts can help you notice the ways in which this country has delivered on the promise of freedom in important ways. But it also enables you to consider the disheartening realizations when those freedoms are not upheld.

esearch by Wendy Smith and others shows that we are capable of embracing paradox, rather than rejecting it. It doesn’t always come naturally. But we simply need to give ourselves permission to allow multiple truths to coexist.

In a paradox mind-set, we allow both of these things to be true. When both are true, we can challenge our either/or assumptions, and be more creative in finding solutions.

When you spot the paradox, allow both things to be true and observe if your mind shifts from solving the unsolvable puzzle (reconciling how can both of these things be true) to more deeply processing the knowledge that you may otherwise have pushed away. This is the greater resilience and creativity that comes with a paradox mind-set.

We simply need to accept that the formidable challenge will require us to be intentional in our approach.

In doing so, we become what I call “gritty patriots.” Psychologist Angela Duckworth defines grit as “passion and perseverance in pursuit of a meaningful, long-term goal.” Love of country is not something we are entitled to; it is something we work toward, with grit.

the characters in the core three modern shows—Discovery, Picard, and Strange New Worlds—are less concerned with professionalism and duty and more concerned with personal morality, authenticity, and teamwork.

Dylan Roth, writing for Fanbyte, suggested that as Star Trek has aged, it has “changed from a series about benign authority to one about stalwart heroes protecting an institution from moral decay.” This is true enough, but I also think there’s something else going on with the modern Trek shows. Namely, the atmosphere and philosophy of the shows is much less comfortable with the maxims of professionalism and duty that were foundational to pre-2017 Star Trek media.

Modern Star Trek, much like older Star Trek, often presents its main characters as moral paragons, but whereas older Trek would usually depict them embodying Starfleet’s ideals in the presence of challenging aliens, modern Trek is more likely to establish their uprightness by contrast with the faceless and untrustworthy institution of Starfleet itself. Both eras do both things, at least occasionally, but the ratio has notably shifted.

WHY THE CHANGE? Part of it probably has to do with the other material that Star Trek writers are drawing from. The ’60s and ’90s-era Trek writers either served in the military themselves or were drawing from science fiction written by people who had. (Gene Roddenberry, the creator of Star Trek, and many of the great science-fiction authors of the mid-twentieth century, including Robert Heinlein, Arthur Clarke, Isaac Asimov, Frank Herbert, and Walter M. Miller Jr., each served in some capacity in the World War II-era U.S. or British armed forces.

difference in leadership style is everywhere between the two eras. The Strange New Worlds version of Capt. Christopher Pike has been repeatedly praised for being more collaborative than commanding (I struggle to remember a time he has ever raised his voice), whereas Capt. Sisko shouts at everyone, as only the great Avery Brooks can shout. Picard’s version of its title character trades all his twentieth-century grouchy gravitas for a more grandfatherly role; his inspirational speeches now seek to buoy his friends’ confidence rather than inspire subordinates to high achievement.

Old-school Sisko reminds his crew of the expectations he has for them and unsubtly critiques their behavior as unbecoming of Starfleet officers. He acknowledges their difficulties (“I know it’s hot. . .”), but leaves no doubt that he expects them to perform their duties as professionals anyway. New-school Tilly motivates her command by making it clear that she sees and hears their concerns, and encourages them to work together by seeing the value in their unique life experiences.

modern Trek writers are far less likely to have served—but are far more likely to have worked in twenty-first-century corporate America, which has a rather different set of norms and concepts of professionalism.

more fundamentally, popular science fiction today—as written by authors like N.K. Jemisin, Martha Wells, and Tamsyn Muir—is more likely to be concerned with questions of identity and combating imperialism. It is also more likely to be written from marginalized perspectives, which have valid reasons to distrust institutions and authority. For many of these writers, concepts like “professionalism” have questionable implications

Besides, nobody likes any of America’s institutions anymore (and for all that Star Trek is ostensibly international, it is a fundamentally American franchise). Gallup’s polling about Americans’ faith in U.S. institutions shows it hovering at or near record-breaking lows, spawning a great deal of hand-wringing from people across the political spectrum. These apparently untrustworthy institutions range from purely political ones (the presidency, the Supreme Court, etc.) to “the church or organized religion” (whatever that means), “banks,” and “newspapers.”

What are professionalism and duty if not the suppression of individual quirks in service of some larger goal or institution? Duty overrides individual desires or assessments of right and wrong.

But older Trek nevertheless believed in duty, because it believed that Starfleet was a fundamentally good institution, even if it may be failed by individual bad or misguided actors. It elevated Starfleet’s regulations and codes of conduct almost to the status of holy wri

it is difficult to be seriously inspired by the notion of duties if one has a deep distrust of the institutions that assign such duties.

Of course the characters written by twenty-first-century authors, who are animated by the same deep distrust of American institutions as the rest of us, are less likely to justify themselves with the language of duty than they are by reference to personal morality and authenticity. And of course they’re going to be skeptical of rank and hierarchy because they don’t believe these things are necessarily signs of actual merit or accomplishment any more than the rest of us do.

Yet I worry. If Star Trek is supposed to start from the assumption that Starfleet and the Federation are quasi-utopian, I worry about what it says about our collective imaginations if we can’t even let the institutions of that fictional utopia be utopian. If we can’t even trust Starfleet, who can we trust?

The 2024 election will not be the usual battle between parties, platforms and policies. It is a battle between those who fundamentally respect and abide by the ground rules of democracy and those who do not.

To underline his case most forcefully, Mr. Biden didn’t need to use his own words. He could rely on the words of his opponent: revenge, retribution, fight like hell, terminate the Constitution, suckers and losers, vermin, poisoning the blood of our country, dictator on Day 1, American carnage. There is no subtext here; it’s all text. As Mr. Biden put it, “We all know who Donald Trump is.”

And yet, apparently, we need to keep reminding ourselves. Otherwise, we fall into the trap of normalization that Mr. Trump laid from the start.

Today he can call for the execution of the chairman of the Joint Chiefs of Staff, or tell the Biden administration to “rot in hell,” or promote a video claiming he is literally a gift from God, and it gets less attention in both mainstream and social media than Mr. Biden tripping over a sandbag.

How did we end up here? Mr. Biden offered one compelling explanation: complacency. “We’ve been blessed so long with a strong, stable democracy, it’s easy to forget why so many before us risked their lives and strengthened democracy,

In that sense, democracy is like vaccines. Few people today have firsthand memories of the horrors of diseases that were rampant before vaccines largely eradicated them, which makes it easier for vaccine hesitancy to take root

Similarly, when a country has no history of living under a dictatorship, it can be easier to lose sight of what it means to live in a representative democracy, and to be caught flat-footed when a real authoritarian comes knocking.

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.
