“We should keep in mind that we’re only at the beginning of what AI can accomplish,” he wrote. “Whatever limitations it has today will be gone before we know it.”

“We should try to balance fears about the downsides of AI—which are understandable and valid—with its ability to improve people’s lives.”

“AI is the next revolution and there is no going back,”

“There is an enormous demand for people who are tech-savvy and who will be the first adopters, who will be the first to figure out what opportunities these technologies open up,”

“Every month there are hundreds more job postings mentioning generative AI,”

“The way things have been done in the past aren’t necessarily the way they need to be done today,” he said, adding that workers and employers should invest in retraining and upskilling where possible.

that transformation is already taking shape, and workers can find ways to use the ChatGPT and other new technology to free them from boring work.

The jobs of the future will require a mind-set shift for employees, several executives said. Rather than viewing generative AI and other machine-learning software as a threat, workers should embrace new technology as a way to free them from less-rewarding work and augment their strengths.

“This is a huge opportunity to advance a lot of professions—allow people to do work that’s, frankly, more stimulating.”

For the hotel chain, that could look like using AI to determine which brand of wine a guest likes, and adjusting recommendations accordingly.

United Airlines Holdings Inc., aims to use AI to do transactions that shouldn’t require a human, such as placing someone in an aisle or window seat depending on their preference, or suggesting a different flight for someone trying to book a tight connection, said Kate Gebo, executive vice president of human resources and labor relations. That leaves employees free to have more complex interactions with customers

services intended to help customers solve emotional problems require solutions a machine can’t provide.

“AI is not sentient. It can’t be emotional. And that is the kind of accountability and reciprocity that is needed…for people to have the outcomes that we’re hoping to provide,”

“Certain business processes could be enhanced,” said Carmen Orr, Yelp’s chief people officer, adding that there are plenty of concerns, too. “We don’t want it for high human-touch things.”

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.

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.

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.

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.”

That’s no accident. In the three decades since the end of the Soviet Union, those men have faced industrial collapse, the disappearance of millions of jobs and declining life expectancy. The war promises to change that downward trajectory, transforming the losers of the past three decades into new heroes

For many Russian men and their families, the war may be a horror. But it’s also the last opportunity to fix their lives.

First, there’s the money. The federal base salary for a soldier is about $2,500 a month, with payment of $39,000 for wounding and up to $65,000 in the case of death. Compared with a median monthly salary of $545, this is a handsome reward — even more so for the approximately 15.3 million Russians living below the poverty line.

there’s much more on offer, too. For those coming back from the front, the state promises fast-tracked entry into civil service jobs, health insurance, free public transportation, as well as free university education and free food at school for their children. And for those who were imprisoned and joined the Wagner private military company, the state grants freedom.

Today’s soldiers live in the shadows of the generation that won the war against Nazism. In Russian public culture, no honor is higher than to be a veteran of the “Great Patriotic War,” something the regime has capitalized on by framing today’s war as a kind of historical re-enactment of World War II.

As one soldier wrote on Telegram in February, the war confers “a sense of belonging to the great male deed, the deed of defending our Motherland.”

By allowing men to escape the difficulties of everyday life — with its low pay and routine frustrations — the war offers a restoration of male self-worth. These men, at last, matter.

Feelings of inferiority, too, are swept aside in the fraternal atmosphere of the front. “It doesn’t matter who you are, how you look,” as one soldier put it. In the communal life of conflict, many of the distinctions of civilian life dissolve. War is an equalizer.

Mistrust of the rich, belief that sanctions actually strengthen the economy and disdain for émigrés all attest to a class-based experience of the conflict. By participating in the war, millions of Russians at the bottom of the social ladder can emerge as the country’s true heroes, ready for the ultimate sacrifice. The risk may be grave and the financial reward uncertain. But the chance to rise in esteem and respect makes the effort worthwhile.

The longer the war drags on, bringing more casualties, loss and broken promises, the harder it may become to sustain such levels of acceptance

it may not. Collective emotional turmoil could deepen the feeling that the war must be won, no matter what. In the absence of an alternative vision of the future, Vladimir Putin and his war will continue to hold sway.

The key issue is not “human-competitive” intelligence (as the open letter puts it); it’s what happens after AI gets to smarter-than-human intelligence. Key thresholds there may not be obvious, we definitely can’t calculate in advance what happens when, and it currently seems imaginable that a research lab would cross critical lines without noticing.

Many researchers steeped in these issues, including myself, expect that the most likely result of building a superhumanly smart AI, under anything remotely like the current circumstances, is that literally everyone on Earth will die. Not as in “maybe possibly some remote chance,” but as in “that is the obvious thing that would happen.”

It’s not that you can’t, in principle, survive creating something much smarter than you; it’s that it would require precision and preparation and new scientific insights, and probably not having AI systems composed of giant inscrutable arrays of fractional numbers.

Absent that caring, we get “the AI does not love you, nor does it hate you, and you are made of atoms it can use for something else.”

Without that precision and preparation, the most likely outcome is AI that does not do what we want, and does not care for us nor for sentient life in general. That kind of caring is something that could in principle be imbued into an AI but we are not ready and do not currently know how.

The likely result of humanity facing down an opposed superhuman intelligence is a total loss

To visualize a hostile superhuman AI, don’t imagine a lifeless book-smart thinker dwelling inside the internet and sending ill-intentioned emails. Visualize an entire alien civilization, thinking at millions of times human speeds, initially confined to computers—in a world of creatures that are, from its perspective, very stupid and very slow. A sufficiently intelligent AI won’t stay confined to computers for long. In today’s world you can email DNA strings to laboratories that will produce proteins on demand, allowing an AI initially confined to the internet to build artificial life forms or bootstrap straight to postbiological molecular manufacturing.

There’s no proposed plan for how we could do any such thing and survive. OpenAI’s openly declared intention is to make some future AI do our AI alignment homework. Just hearing that this is the plan ought to be enough to get any sensible person to panic. The other leading AI lab, DeepMind, has no plan at all.

An aside: None of this danger depends on whether or not AIs are or can be conscious; it’s intrinsic to the notion of powerful cognitive systems that optimize hard and calculate outputs that meet sufficiently complicated outcome criteria.

I didn’t also mention that we have no idea how to determine whether AI systems are aware of themselves—since we have no idea how to decode anything that goes on in the giant inscrutable arrays—and therefore we may at some point inadvertently create digital minds which are truly conscious and ought to have rights and shouldn’t be owned.

I refrained from signing because I think the letter is understating the seriousness of the situation and asking for too little to solve it.

the thing about trying this with superhuman intelligence is that if you get that wrong on the first try, you do not get to learn from your mistakes, because you are dead. Humanity does not learn from the mistake and dust itself off and try again, as in other challenges we’ve overcome in our history, because we are all gone.

If we held anything in the nascent field of Artificial General Intelligence to the lesser standards of engineering rigor that apply to a bridge meant to carry a couple of thousand cars, the entire field would be shut down tomorrow.

We are not on course to be prepared in any reasonable time window. There is no plan. Progress in AI capabilities is running vastly, vastly ahead of progress in AI alignment or even progress in understanding what the hell is going on inside those systems

Many researchers working on these systems think that we’re plunging toward a catastrophe, with more of them daring to say it in private than in public; but they think that they can’t unilaterally stop the forward plunge, that others will go on even if they personally quit their jobs.

This is a stupid state of affairs, and an undignified way for Earth to die, and the rest of humanity ought to step in at this point and help the industry solve its collective action problem.

When the insider conversation is about the grief of seeing your daughter lose her first tooth, and thinking she’s not going to get a chance to grow up, I believe we are past the point of playing political chess about a six-month moratorium.

The moratorium on new large training runs needs to be indefinite and worldwide. There can be no exceptions, including for governments or militaries. If the policy starts with the U.S., then China needs to see that the U.S. is not seeking an advantage but rather trying to prevent a horrifically dangerous technology which can have no true owner and which will kill everyone in the U.S. and in China and on Earth

Here’s what would actually need to be done:

Shut down all the large GPU clusters (the large computer farms where the most powerful AIs are refined). Shut down all the large training runs

Put a ceiling on how much computing power anyone is allowed to use in training an AI system, and move it downward over the coming years to compensate for more efficient training algorithm

Track all GPUs sold. If intelligence says that a country outside the agreement is building a GPU cluster, be less scared of a shooting conflict between nations than of the moratorium being violated; be willing to destroy a rogue datacenter by airstrike.

Frame nothing as a conflict between national interests, have it clear that anyone talking of arms races is a fool

Make it explicit in international diplomacy that preventing AI extinction scenarios is considered a priority above preventing a full nuclear exchange, and that allied nuclear countries are willing to run some risk of nuclear exchange if that’s what it takes to reduce the risk of large AI training runs.

when your policy ask is that large, the only way it goes through is if policymakers realize that if they conduct business as usual, and do what’s politically easy, that means their own kids are going to die too.

an "ACA for All" system would prevent government from operating health insurance while allowing it to regulate and finance health insurance for most Americans. The ACA for All would not be "socialized medicine" -- where government not only finances healthcare but supplies it through public hospitals, clinics, and the direct employment of clinicians. ACA for All would continue to rely on private industry (private doctors and private hospitals) and personal responsibility, and would limit the government's role in healthcare delivery.

A Republican plan for universal healthcare would offer those with non-employer-based coverage an adequately sized tax deduction, big enough to cover the cost of a family health insurance plan. And, for the first time since the 1940s, individuals would pay taxes on the value of employer-based health insurance above a certain threshold (based on the average costopens in a new tab or window of a family health insurance plan).

“It is unfortunate to frame this as an arms race,” Mr. Tegmark said. “It is more of a suicide race. It doesn’t matter who is going to get there first. It just means that humanity as a whole could lose control of its own destiny.” 

Messrs. Musk and Wozniak have both voiced concerns about AI technology. Mr. Musk on Wednesday tweeted that developers of the advanced AI technology “will not heed this warning, but at least it was said.”

Yann LeCun, chief AI scientist at Meta Platforms Inc., on Tuesday tweeted that he didn’t sign the letter because he disagreed with its premise. 

Mr. Mostaque, Stability AI’s CEO, said in a tweet Wednesday that although he signed the letter, he didn’t agree with a six-month pause. “It has no force but will kick off an important discussion that will hopefully bring more transparency & governance to an opaque area.”

Mr. Tegmark said many companies feel “crazy commercial pressures” to add advanced AI technology into their products. A six-month pause would allow the industry “breathing room,” without disadvantaging ones that opt to move carefully

The letter said a pause should be declared publicly and be verifiable and all key actors in the space should participate. “If such a pause cannot be enacted quickly, governments should step in and institute a moratorium,” it said

AI labs and experts can use this time to develop a set of shared safety rules for advanced AI design that should be audited and overseen by outside experts, the authors wrote.

“I don’t think we can afford to just go forward and break things,” said Mr. Bengio, who shared a 2018 Turing award for inventing the systems that modern AI is built on. “We do need to take time to think through this collectively.”

For decades — and particularly since the 2008 recession — politicians in both parties have mounted a strident campaign against government funding for the liberal arts. They express a growing disdain for any courses not explicitly tailored to the job market and outright contempt for the role the liberal arts-focused university has played in American society.

Former Gov. Scott Walker’s assault on higher education in Wisconsin formed the bedrock of many later conservative attacks. His work severely undermined a state university system that was once globally admired. Mr. Walker reportedly attempted to cut phrases like “the search for truth” and “public service” — as well as a call to improve “the human condition” — from the University of Wisconsin’s official mission statement

But blue states also regularly cut higher education funding, sometimes with similar rationales. In 2016, Matt Bevin, the Republican governor of Kentucky at the time, suggested that students majoring in the humanities shouldn’t receive state funding. The current secretary of education, Miguel Cardona, a Democrat, seems to barely disagree. “Every student should have access to an education that aligns with industry demands and evolves to meet the demands of tomorrow’s global work force,” he wrote in December.

Federal funding reflects those priorities. The National Endowment for the Humanities’ budget in 2022 was just $180 million. The National Science Foundation’s budget was about 50 times greater, having nearly doubled within two decades.

What were students meant to think? As the cost of higher education rose, substantially outpacing inflation since 1990, students followed funding — and what politicians repeatedly said about employability — into fields like business and computer science. Even majors in mathematics were hit by the focus on employability.

Universities took note and began culling. One recent study showed that history faculty across 28 Midwestern universities had dropped by almost 30 percent in roughly the past decade. Classics programs, including the only one at a historically Black college, were often simply eliminated.

Higher education, with broad study in the liberal arts, is meant to create not merely good workers but good citizens

this is a grim and narrow view of the purpose of higher education, merely as a tool to train workers as replaceable cogs in America’s economic machine, to generate raw material for its largest companies.

Citizens with knowledge of their history and culture are better equipped to lead and participate in a democratic society; learning in many different forms of knowledge teaches the humility necessary to accept other points of view in a pluralistic and increasingly globalized society.

In 1947, a presidential commission bemoaned an education system where a student “may have gained technical or professional training” while being “only incidentally, if at all, made ready for performing his duties as a man, a parent and a citizen.” The report recommended funding to give as many Americans as possible the sort of education that would “give to the student the values, attitudes, knowledge and skills that will equip him to live rightly and well in a free society,” which is to say the liberal arts as traditionally understood. The funding followed.

The report is true today, too

the American higher education system is returning to what it once was: liberal arts finishing schools for the wealthy and privileged, and vocational training for the rest.

Reversing this decline requires a concerted effort by both government and educational actors

renewed funding for the liberal arts — and especially the humanities — would support beleaguered departments and show students that this study is valuable and valued.

At the university level, instituting general education requirements would guarantee that even students whose majors have nothing to do with the humanities emerged from college equipped to think deeply and critically across disciplines.

Liberal arts professors must also be willing to leave their crumbling ivory towers and the parochial debates about their own career path, in order to engage directly in public life

Apple and Google said they allow users to create audiobooks free of charge that use digitally replicated human voices. The voices featured in audiobooks generated by Apple and Google come from real people, whose voices helped train their automated-narration engines.

Ms. Papel said there is still plenty of work for professional narrators because the new era of AI auto-narration is just getting under way, though she said that might not be the case in the future.

“From what I can see, human narrators are freaking out,

Melissa Papel, a Paris-born actress who records from her home studio in Los Angeles, said she recorded eight hours of content for DeepZen, reading in French from different books. “One called for me to read in an angry way, another in a disgusted way, a humorous way, a dramatic way,” she said.

Charles Watkinson, director of the University of Michigan Press, said the publisher has made about 100 audiobooks using Google’s free auto-narrated audiobook platform since early last year. The new technology made those titles possible because it eliminated the costs associated with using a production studio, support staff and human narrators.

“I understood that they would use my voice to teach software how to speak more humanly,” Ms. Papel said. “I didn’t realize they could use my voice to pronounce words I didn’t say. That’s incredible.”

DeepZen pays its narrators a flat fee plus a royalty based on the revenue the company generates from different projects. The agreements span multiple years

a national union that represents performers, including professional audiobook narrators, said he expects AI to eventually disrupt the industry.

Audiobook sales rose 7% last year, according to the Association of American Publishers, while print book sales declined by 5.8%, according to book tracker Circana BookScan.

eepZen says it has signed deals with 35 publishers in the U.S. and abroad and is working with 25 authors.

Josiah Ziegler, a psychiatrist in Fort Collins, Colo., last year created Intellectual Classics, which focuses on nonfiction works that are out of copyright and don’t have an audiobook edition. 

He chose Mr. Herrmann as the narrator for “The War with Mexico,” a work by Justin H. Smith that won the 1920 Pulitzer Prize for history whose audiobook version Dr. Ziegler expects to publish later this year.

DeepZen, which has created nearly a hundred audiobooks featuring Mr. Herrmann’s voice, is pursuing the rights of other well-known stars who have died.

If all of this sounds familiar, it’s because we basically saw this same environmental dynamic play out several years ago with tech’s last big obsession: Crypto and web3. In that case, Bitcoin emerged as the industry’s obvious environmental sore spot due to the vast amounts of energy needed to mine coins in its proof of work model. Some estimates suggest Bitocin alone requires more energy every year than Norway’s annual electricity consumption.

rs of criticism from environmental activists however led the crypto industry to make some changes. Ethereum, the second largest currency on the blockchain, officially switched last year to a proof of stake model which supporters claim could reduce its power usage by over 99%. Other smaller coins similarly were designed with energy efficiency in mind. In the grand scheme of things, large language models are still in their infancy and it’s far from certain how its environmental report card will play out.

The Musk messages also reveal how some of the richest and most powerful men in the world treat actual billions of dollars with a level of care more appropriate for a 3-year-old tossing around Monopoly cash.

Oracle’s founder, Larry Ellison, essentially writes Musk a blank check over text, pledging, “A billion … or whatever you recommend.” The venture capitalist Marc Andreessen unsolicitedly offers Musk “$250M with no additional work required.” And Michael Grimes, a top investment banker at Morgan Stanley, proposes a meeting with Bankman-Fried as a way to “get us $5bn equity in an hour.”

The blitheness is the point. It is a total power move to talk about getting “$5bn in equity in an hour” the same way we mere mortals talk about Venmo-ing a friend $15 for lunch. The texts make it clear that these men are fundamentally alienated from the rest of the world by their wealth.

“These are absolutely not normal people with a normal understanding of the world.”

The men in Musk’s phone also appear wildly confident in their own abilities and those of their peers. Mathias Döpfner, the CEO of the media conglomerate Axel Springer, infamously texted Musk his bullet-pointed plan for Twitter, which began with the line item “1.),, Solve Free Speech.”

They teach us what happens when a small group of people with too much money come to view that money not just as a reward for success, but as its own form of merit—a specious achievement that totally alienates them from reality.

Ultimately, Exhibit H documents the loneliness and isolation of being the world’s richest man. As told via the texts, the seed of Musk’s Twitter purchase was planted by sycophants deferential to the billionaire who will never give him hard, truthful advice, because they wish to stay close to him.

the one time he receives actual, honest feedback from Agrawal, Musk behaves aggressively and impulsively, sealing his fate.

Until recently, the people said, Meta executives viewed the company’s reliance on China to make Oculus virtual reality headsets as a relatively minor concern because the company’s core focus was its social media and messaging apps.

All that has changed now that Meta has rebranded itself as a hardware company

“Meta is building a complicated hardware product. You can’t just turn on a dime and make it elsewhere,”

Facebook’s public criticism of China began in 2019 when Zuckerberg warned, in a speech at Georgetown University, that China was exporting a dangerous vision for the internet to the rest of the world — and noted that Facebook was abandoning its efforts to break into that country’s market.

The anti-China stance has since extended into a full-blown corporate strategy. Nick Clegg, the company’s president, wrote an op-ed attacking China in The Washington Post in 2020, the same year Zuckerberg attacked China in a congressional antitrust hearing.

At the antitrust hearing in Congress in 2020, Zuckerberg used his opening remarks to attack China in terms that went much further than his industry peers. He said it was “well-documented that the Chinese government steals technology from American companies,” and repeated that the country was “building its own version of the internet” that went against American values. He described Facebook as a “proudly American” company and noted that TikTok was the company’s fastest-growing rival.

“They were trying to find things that [Zuckerberg] could agree with Trump on, and it’s a pretty slim list,” said one of the people, describing how the company landed on its anti-China strategy. “If you’re not going to try to be in this country anyway, you might as well use it to your political advantage by contrasting yourself with Apple and TikTok.”

Today, China’s economy is roughly five times the size of India’s. The average citizen of China has an economic output of almost $13,000 a year, while the average Indian’s is less than $2,500

In human-development indicators, the contrast is even sharper, with infant mortality rates much higher in India, life expectancy lower and access to sanitation less prevalent.

The divergence, analysts say, comes down largely to China’s central consolidation of policy power, an earlier start in opening up its economy to market forces starting in the late 1970s, and its single-minded focus on export-led growth.

China took the first-mover advantage and then compounded its dominance as it pursued its plans relentlessly.

India started opening its quasi-socialist economy nearly a decade later. Its approach remained piecemeal, constrained by tricky coalition politics and the competing interests of industrialists, unions, farmers and factions across its social spectrum.

“There is that element where China is a natural role model — not for its politics, but for the sheer efficiency,”

The world now has a radically different power structure than it did in 1990. China has already made itself the world’s factory, all but closing off any path India could take to competitive dominance in export-driven manufacturing.

A “Make in India” campaign, inaugurated by Mr. Modi in 2014, has been stuttering ever since. Wage costs are lower in India than in China, but much of the work force is poorly educated, and the country has struggled to attract private investment with its restrictive labor laws and other impediments to business, including lingering protectionism.

service-sector growth can go only so far in reaping India’s promise of a demographic dividend, or blunt the peril of an unemployment crisis. Hundreds of millions of people can’t find jobs or are underemployed in work that pays too little.

the employment entrance exams at government agencies. These jobs are still coveted as private sector work remains limited and less stable.

650,000 students will apply for just 600 or 700 jobs in the national civil service this year.

The civil service is a tiny part of the work force, but it is prestigious — in part because it comes with job security for life. Most applicants spend years, and a big chunk of their family’s savings, and still fail to make the cut.

“Here there is no enterprise, no companies,” Mr. Kumar said. For any young person, “the question comes, ‘What next? What can I do?’”

The lessons Mr. Modi is taking from China are most apparent in his push for infrastructure development, investing heavily in highways, railways and airports to improve supply chains and connectivity.

India has quintupled its annual spending on roads and railways during Mr. Modi’s nine years in power

As Mr. Modi has boxed in opponents, cowed the press and overwhelmed independent elements of civil society, his government has lashed out at expressions of concern from abroad as evidence of a colonial plot to undermine India or a lack of understanding of India’s “civilizational” approach — both elements that diplomats had long heard in China’s own defensiveness.

All the while, the increasing militancy of his Hindu nationalist supporters, as arms of the state hang back and give perpetrators a free pass, exacerbates India’s religious fault lines and clashes that threaten to disrupt India’s rise.

Even as India tries to align its growing technological and economic capacity to capitalize on the Western tensions with China, it is determined to stick to its neutrality and maintain a balancing act between the United States and Russia. There is also the question of whether the West’s shift from China, the linchpin of the global economy, is a temporary recalibration or a more fundamental one.

“China took advantage of a favorable geopolitical moment to really transform itself by having access to technology, to capital, to markets led by the United States. It took advantage of that to build itself up,” Mr. Saran said. “This could be that moment for India.”

“It’s shoot first, ask questions later,”

Each one of these incidents resulted from unique events. But activists and researchers say they stem from a convergence of bigger factors — increased fear of crime and an attendant surge in gun ownership, increasingly extreme political messaging on firearms, fearmongering in the media and marketing campaigns by the gun industry that portray the suburban front door as a fortified barrier against a violent world.

“The gun lobby markets firearms as something you need to defend yourself — hammers in search of nails,”

The perception that crime, especially violent gun crime, has increased is not a manufactured myth. National murder rates have climbed by about a third since 2019, according to government data, even accounting for modest declines in fatal shootings over the past 18 months.

Gun purchases rose during the pandemic and the unrest and racial-justice protests after the murder of George Floyd. Nearly 20 percent of American households bought a gun from March 2020 to March 2022, and about 5 percent of Americans bought a gun for the first time,

More than 30 states also have “stand your ground” laws. Some have recently strengthened their “castle doctrine” laws, making it more difficult to prosecute homeowners who claim self-defense in a shooting.

“People become paranoid and over-worried — and then comes an unannounced knock on their door,”

But several large-scale studies have suggested that the laws have few benefits, increase the likelihood of gun violence and might discriminate against minority groups, especially Black people.

The effect of self-defense laws protecting homeowners and gun owners is fiercely debated, with proponents arguing that their mere presence deters criminal behavior or civil disorder

shootings in which white people shot Black people were nearly three times as likely to be found “justified” compared with cases where white people shot other white people.

A 2023 analysis of recent academic research by the nonpartisan RAND Corporation found no evidence that such laws had the deterrent effect that their sponsors claimed, and there was some indication, while not conclusive, that the laws might account for some increases in gun violence.

weapons were actually more likely to be used in suicides, discharged accidentally, stolen or brandished in domestic disputes, than used to fend off an external attack.

The National Rifle Association and other gun-rights groups have long disputed such assessments, citing surveys that show far greater use of weapons for legitimate self-defense.

About a third of the roughly 16,700 gun owners surveyed in a study led by William English, a Georgetown University business school professor, said they had used their guns for self-defense, prompting Mr. English to estimate that as many as 1.6 million people in the country had defended themselves with a weapon that year.

Other pundits and entrepreneurs say concerns about the tech are overblown and risk pushing regulators to block innovations that could help people and boost tech company profits.

Last year, politicians and policymakers around the world also grappled to make sense of how AI will fit into society. Congress held multiple hearings. President Biden issued an executive order saying AI was the “most consequential technology of our time.” The United Kingdom convened a global AI forum where Prime Minister Rishi Sunak warned that “humanity could lose control of AI completely.” The concerns include the risk that “generative” AI — which can create text, video, images and audio — can be used to create misinformation, displace jobs or even help people create dangerous bioweapons.

Since 2016, there have been two competing visions for the Democratic Party. One is the promise that began with Barack Obama of a multiracial coalition that would grow stronger as America’s demographics shifted; the other is the political revolution championed by Bernie Sanders as a way to unite nonvoters with the working class

Ms. Ocasio-Cortez bridges the gap between the two

what’s clear is that at a time when Democrats are struggling, she is quietly laying the groundwork to build a coalition broader than the one she came to power with, unafraid to take risks along the way.

After five years in Congress, she has emerged as a tested navigator of its byzantine systems, wielding her celebrity to further her political aims in a way few others have.

Three terms in, one gets the sense that we’re witnessing a skilled tactician exiting her political adolescence and coming into her own as a veteran operator out to reform America’s most dysfunctional political body.

To grasp what sets Ms. Ocasio-Cortez apart from many of her colleagues, you have to understand where she finds allies

In 2019, she and Senator Ted Cruz of Texas considered joining forces to write a bill that would bar former members of Congress from becoming lobbyists. Asked why she would consider an alliance with someone so loathed by liberals, she said, “I will swallow all of my distaste in this situation because we have found a common interest.”

It was a window into the politician she would become: pragmatic and results-driven, willing to work with people she considers her political adversaries, at least on legislation that appeals to her base

She has attributed the success of these efforts at least in part to her role as the second most powerful Democrat on the House Oversight Committee, which she said has “opened many windows” for collaboration.

while these bills may seem like small victories, they are more than that because, in a sense, she is redefining what bipartisanship looks like in Washington.

For decades, bipartisanship has meant bringing together moderates, lobbyists and establishment insiders to produce watered-down legislation unpalatable to many voters in both political partie

What Ms. Ocasio-Cortez is doing is different; she’s uniting politicians on the fringes of American politics around a broadly popular set of policies.

Americans in both parties overwhelmingly say that they don’t trust the government to do the right thing and that donors and lobbyists have too much sway over the legislative process.

more than 8 in 10 Americans believe politicians “are more focused on fighting each other than on solving problems.” One-fifth of respondents said lack of bipartisan cooperation was the biggest problem with the political system.

Ms. Ocasio-Cortez’s efforts to reach out to Republicans are offering what a sizable portion of Americans want from Congress: a return to getting things done.

The few policy matters on which progressives and conservatives align often boil down to a distrust of politicians and of big corporations, particularly technology companies and pharmaceutical giants.

Ms. Ocasio-Cortez has shrewdly made those causes her passion, building alliances with conservative colleagues interested in holding these industries accountable.

Last spring, she cosponsored a bill with, among others, Brian Fitzpatrick, a moderate Republican from Pennsylvania, and Matt Gaetz, the Florida rabble-rouser who has become one of Mr. Trump’s most steadfast allies. The legislation would bar members of Congress from trading individual stocks, a measure that as of the fall of 2022 was supported by nearly 70 percent of voters across party lines.

On Gaza, too, she has been willing to buck other members of her party to pursue an agenda that a majority of voters support. She was one of the first Democrats to call for a cease-fire; within weeks, nearly 70 percent of Americans said Israel should call one and try to negotiate with Hamas.

In March, Ms. Ocasio-Cortez was accosted by a handful of protesters who demanded that she call Israel’s war in Gaza a genocide.

Less than three weeks later, Ms. Ocasio-Cortez did accuse Israel of genocide and chastised the White House for providing military aid to the country while it blockaded Gaza. “If you want to know what an unfolding genocide looks like,” Ms. Ocasio-Cortez said in a speech on the House floor, “open your eyes. It looks like the forced famine of 1.1 million innocents. It looks like thousands of children eating grass as their bodies consume themselves, while trucks of food are slowed and halted just miles away.”

Last month, she voted against providing additional funding for Israel. Those were unpopular positions in Congress, where unconditional support for the country remains the norm, but they put her in line with a majority of Democratic voters.

These stances haven’t been enough to quell the doubts from a faction of the left that helped get her elected. Over the past few weeks, some have accused her of caving in to pressure from moderate Democrats

. Ms. Ocasio-Cortez has taken much of the heat from leftist activists who see her as a symbol of the contradictions and compromises inherent in the political system. It may not be realistic to expect absolute purity from her; she is, after all, a politician. But these critiques overlook the promise of what she’s doing behind the scenes.

Democratic pollsters and strategists are searching for ways for Mr. Biden to win back Muslims and Arab Americans in swing states such as Michigan and Georgia, recent college graduates who hoped to have their student debt forgiven, immigrant-rights activists and Latinos.

Some of the betrayal these voters feel was hardly the president’s fault; he was hampered on student loan debt by a federal judiciary stacked with judges sympathetic to conservative legal arguments, and Congress refused to pass the comprehensive immigration bill he supported in 2021, which would have provided legal status to as many as 11 million undocumented immigrants.

A more gifted orator might have been able to make the structural impediments in his way clear to voters, while also putting forth a proactive vision for dismantling the core problems baked into our politics.

In that, someone like Ms. Ocasio-Cortez, who endorsed Mr. Biden for re-election in 2023, may be able to help. She’s the Democratic Party’s most charismatic politician since Barack Obama and its most ardent populist since Bernie Sanders.

she can offer voters something more substantial than a hollow rebuke of Trumpism

Last month, when the journalist Mehdi Hasan asked her how she’d respond to “a young progressive or Arab American who says to you, ‘I just can’t vote for Biden again after what he’s enabled in Gaza,’” Ms. Ocasio-Cortez said a vote for Mr. Biden didn’t necessarily mean an endorsement of all his policies. “Even in places of stark disagreement, I would rather be organizing under the conditions of Biden as an opponent on an issue than Trump,” she said. It was a shrewd political maneuver, designed to distance herself from Democrats who support Israel unconditionally, while meeting voters — some of whom have lost family members in Gaza — where they are

There are, of course, limits to this strategy. Some on the left see Ms. Ocasio-Cortez’s endorsement of Mr. Biden as a betrayal of progressive values, particularly in the wake of the climbing death toll in Gaza.

The moderate Republicans who turned out for Mr. Biden in 2020 might shrink from a Democratic Party led by someone they consider an outspoken progressive.

But for every moderate or leftist voter lost with a strategy like Ms. Ocasio-Cortez’s, the Democratic Party may be able to win someone new — from the pool of disillusioned Americans who feel shut out of the political process.

Dr. Monteiro and his colleagues developed a food classification system called Nova, named after the Portuguese and Latin words for “new.” It has since been adopted by researchers across the world.

Unprocessed or minimally processed foods, like fresh or frozen fruits and vegetables, beans, lentils, meat, poultry, fish, eggs, milk, plain yogurt, rice, pasta, corn meal, flour, coffee, tea and herbs and spices.

Processed culinary ingredients, such as cooking oils, butter, sugar, honey, vinegar and salt.

If you look at the ingredient list and you see things that you wouldn’t use in home cooking, then that’s probably an ultraprocessed food,”

his group includes freshly baked bread, most cheeses and canned vegetables, beans and fish. These foods may contain preservatives that extend shelf life.

Ultraprocessed foods made using industrial methods and ingredients you wouldn’t typically find in grocery stores — like high-fructose corn syrup, hydrogenated oils and concentrated proteins like soy isolate.

They often contain additives like flavorings, colorings or emulsifiers to make them appear more attractive and palatable.

Think sodas and energy drinks, chips, candies, flavored yogurts, margarine, chicken nuggets, hot dogs, sausages, lunch meats, boxed macaroni and cheese, infant formulas and most packaged breads, plant milks, meat substitutes and breakfast cereals.

Processed foods made by combining foods from Category 1 with the ingredients of Category 2 and preserving or modifying them with relatively simple methods like canning, bottling, fermentation and baking

That has led to debate among nutrition experts about whether it’s useful for describing the healthfulness of a food, partly since many UPFs — like whole grain breads, flavored yogurts and infant formulas — can provide valuable nutrients

Most research linking UPFs to poor health is based on observational studies, in which researchers ask people about their diets and then track their health over many years.

Why might UPFs be harmful?

In a large review of studies that was published in 2024, scientists reported that consuming UPFs was associated with 32 health problems, with the most convincing evidence for heart disease-related deaths, Type 2 diabetes and common mental health issues like anxiety and depression.

Such studies are valuable, because they can look at large groups of people — the 2024 review included results from nearly 10 million — over the many years it can take for chronic health conditions to develop

She added that the consistency of the link between UPFs and health issues increased her confidence that there was a real problem with the foods.

But the observational studies also have limitations,

It’s true that there is a correlation between these foods and chronic diseases, she said, but that doesn’t mean that UPFs directly cause poor health.

Dr. O’Connor questioned whether it’s helpful to group such “starkly different” foods — like Twinkies and breakfast cereals — into one category. Certain types of ultraprocessed foods, like sodas and processed meats, are more clearly harmful than others

UPFs like flavored yogurts and whole grain breads, on the other hand, have been associated with a reduced risk of developing Type 2 diabetes.

Clinical trials are needed to test if UPFs directly cause health problems, Dr. O’Connor said. Only one such study, which was small and had some limitations, has been done, s

In that study, published in 2019, 20 adults with a range of body sizes lived in a research hospital at the National Institutes of Health for four weeks. For two weeks, they ate mainly unprocessed or minimally processed foods, and for another two weeks, they ate mainly UPFs. The diets had similar amounts of calories and nutrients, and the participants could eat as much as they wanted at each meal.

During their two weeks on the ultraprocessed diet, participants gained an average of two pounds and consumed about 500 calories more per day than they did on the unprocessed diet

During their time on the unprocessed diet, they lost about two pounds.

That finding might help explain the link between UPFs, obesity and other metabolic conditions

The Nova system notably doesn’t classify foods based on nutrients like fat, fiber, vitamins or minerals. It’s “agnostic to nutrition,”

There are many “strong opinions” about why ultraprocessed foods are unhealthy, Dr. Hall said. “But there’s actually not a lot of rigorous science” on what those mechanisms are

Because UPFs are often cheap, convenient and accessible, they’re probably displacing healthier foods from our diets

the foods could be having more direct effects on health. They can be easy to overeat — maybe because they contain hard-to-resist combinations of carbohydrates, sugars, fats and salt, are high-calorie and easy to chew

It’s also possible that resulting blood sugar spikes may damage arteries or ramp up inflammation, or that certain food additives or chemicals may interfere with hormones, cause a “leaky” intestine or disrupt the gut microbiome.

Researchers, including Dr. Hall and Dr. Davy, are beginning to conduct small clinical trials that will test some of these theories.

most researchers think there are various ways the foods are causing harm. “Rarely in nutrition is there a single factor that fully explains the relationship between foods and some health outcome,”

In 2014, Dr. Monteiro helped write new dietary guidelines for Brazil that advised people to avoid ultraprocessed foods.

Other countries like Mexico, Israel and Canada have also explicitly recommended avoiding or limiting UPFs or “highly processed foods.”

The U.S. dietary guidelines contain no such advice, but an advisory committee is currently looking into the evidence on how UPFs may affect weight gain, which could influence the 2025 guidelines.

It’s difficult to know what to do about UPFs in the United States, where so much food is already ultraprocessed and people with lower incomes can be especially dependent on them,

“At the end of the day, they are an important source of food, and food is food,” Dr. Mattei added. “We really cannot vilify them,”

While research continues, expert opinions differ on how people should approach UPFs.

the safest course is to avoid them altogether

to swap flavored yogurt for plain yogurt with fruit, for example, or to buy a fresh loaf from a local bakery instead of packaged bread, if you can afford to do so

Dr. Vadiveloo suggested a more moderate strategy, focusing on limiting UPFs that don’t provide valuable nutrients, like soda and cookies

She also recommended eating more fruits, vegetables, whole grains (ultraprocessed or not), legumes, nuts and seeds.

Cook at home as much as you can, using minimally processed foods
