“So far we’re seeing basic agreement with our best model of the universe, but we’re also seeing some potentially interesting differences that could indicate that dark energy is evolving with time,”

When the scientists combined their map with other cosmological data, they were surprised to find that it did not quite agree with the otherwise reliable standard model of the universe, which assumes that dark energy is constant and unchanging. A varying dark energy fit the data points better.

“It’s certainly more than a curiosity,” Dr. Palanque-Delabrouille said. “I would call it a hint. Yeah, it’s not yet evidence, but it’s interesting.”

But this version of dark energy is merely the simplest one. “With DESI we now have achieved a precision that allows us to go beyond that simple model,” Dr. Palanque-Delabrouille said, “to see if the density of dark energy is constant over time, or if it has some fluctuations and evolution with time.”

“While combining data sets is tricky, and these are early results from DESI, the possible evidence that dark energy is not constant is the best news I have heard since cosmic acceleration was firmly established 20-plus years ago.”

praised the new survey as “superb data.” The results, she said, “open the potential for a new window into understanding dark energy, the dominant component of the universe, which remains the biggest mystery in cosmology. Pretty exciting.”

what if dark energy were not constant as the cosmological model assumed?

At issue is a parameter called w, which is a measure of the density, or vehemence, of the dark energy. In Einstein’s version of dark energy, this number remains constant, with a value of –1, throughout the life of the universe. Cosmologists have been using this value in their models for the past 25 years.

Dark energy took its place in the standard model of the universe known as L.C.D.M., composed of 70 percent dark energy (Lambda), 25 percent cold dark matter (an assortment of slow-moving exotic particles) and 5 percent atomic matter. So far that model has been bruised but not broken by the new James Webb Space Telescope

As a measure of distance, the researchers used bumps in the cosmic distribution of galaxies, known as baryon acoustic oscillations. These bumps were imprinted on the cosmos by sound waves in the hot plasma that filled the universe when it was just 380,000 years old. Back then, the bumps were a half-million light-years across. Now, 13.5 billion years later, the universe has expanded a thousandfold, and the bumps — which are now 500 million light-years across — serve as convenient cosmic measuring sticks.

The DESI scientists divided the past 11 billion years of cosmic history into seven spans of time. (The universe is 13.8 billion years old.) For each, they measured the size of these bumps and how fast the galaxies in them were speeding away from us and from each other.

When the researchers put it all together, they found that the usual assumption — a constant dark energy — didn’t work to describe the expansion of the universe. Galaxies in the three most recent epochs appeared closer than they should have been, suggesting that dark energy could be evolving with time.

Dr. Riess of Johns Hopkins, who had an early look at the DESI results, noted that the “hint,” if validated, could pull the rug out from other cosmological measurements, such as the age or size of the universe. “This result is very interesting and we should take it seriously,” he wrote in his email. “Otherwise why else do we do these experiments?”

He is concerned that masters of the A.I. universes are developing systems that will expand chasms of inequality. He fears the transition to A.I. will be so abrupt that entire professional fields will be left doing menial jobs, or nothing, stripping people of dignity and unleashing floods of “despair.”

Father Benanti, who does not believe in the industry’s ability to self-regulate and thinks some rules of the road are required in a world where deep fakes and disinformation can erode democracy.

He shares his insights with Pope Francis, who in his annual World Day of Peace message on Jan. 1 called for a global treaty to ensure the ethical development and use of AI to prevent a world devoid of human mercy, where inscrutable algorithms decide who is granted asylum, who gets a mortgage, or who, on the battlefield, lives or dies.

raises enormous questions about redistributing wealth in an A.I. dominant universe.

he pursued an engineering degree at Sapienza University in Rome. It wasn’t enough.“I started to feel that something was missing,” he said, explaining that his advancement as an engineering student erased the mystique machines held for him. “I simply broke the magic.”

He left Rome to study in Assisi, the home of St. Francis, and over the next decade, took his final vows as a friar, was ordained as a priest and defended his dissertation on human enhancement and cyborgs. He got his job at the Gregorian, and eventually as the Vatican’s IT ethics guy.

In 2017, Cardinal Ravasi organized an event at the Italian embassy to the Holy See where Father Benanti gave a talk on the ethics of A.I. Microsoft officials in attendance were impressed and asked to stay in touch. That same year, the Italian government asked him to contribute to A.I. policy documents and the next year he successfully applied to sit on its commission for developing a national A.I. strategy.

Francis, he said, didn’t at first realize what Microsoft really did, but liked that Mr. Smith took out of his pocket one of the pope’s speeches on social media and showed the pontiff the concerns the business executive had highlighted and shared.

e said, arguing that as ancient Roman augurs turned to the flight of birds for direction, A.I., with its enormous grasp of our physical, emotional and preferential data, could be the new oracles, determining decisions, and replacing God with false idols.

“It’s something old that probably we think that we left behind,” the friar said, “but that is coming back.”

Early 2017 Gallup data echoed this. It showed 32 percent of Republicans suddenly liked the man who had just interfered in an American election.

But a significant and influential segment of the party has demonstrated a tendency toward a brand of moral relativism and even authoritarianism that creates an opening for giving Putin a pass.

Maybe these Republicans just disliked Biden that much, or maybe they saw something admirable in Putin’s strongman mystique (a sentiment Trump has spent years cultivating). It certainly wouldn’t be the only evidence of Trump supporters flirting with the merits of authoritarianism.

Regardless, the data show how, when these loud voices on the right project softness on Putin or his invasion of Ukraine, there’s a willingness to hear that out — even if the base doesn’t actually like Putin. Influential voices on the right have spent years creating a permission structure for shrugging at things like Navalny’s death (see: Jamal Khashoggi).

there’s been little in the way of a desire to fight back against these noisy and influential forces — in part because that would entail going against the most powerful Republican and the onetime most influential conservative commentator.

The latest study looked at data from 126,972 people over the study period. It found that in 2015, 4.2 percent of Medicaid enrollees under the age of 17 in Maryland had overlapping prescriptions of three or more different classes of psychiatric medications. That figure rose to 4.6 percent in 2020.

he trickiest question may be how to prevent abuse. AI generators have technological boundaries, but not morals, and it’s relatively easy for users to trick them into creating content that depicts violence, rape, sex with children or a celebrity — or even a crush from work who never consented to appear

In some cases, the engines themselves are trained on porn images whose subjects didn’t explicitly agree to the new use. Currently, no federal laws protect the victims of nonconsensual deepfakes.

Adult entertainment is a giant industry accounting for a substantial chunk of all internet traffic: Major porn sites get more monthly visitors and page views than Amazon, Netflix, TikTok or Zoom

The industry is a habitual early adopter of new technology, from VHS to DVD to dot com. In the mid-2000s, porn companies set up massive sites where users upload and watch free videos, and ad sales foot the bills.

At last year’s AVN conference, Steven Jones said his peers looked at him “like he was crazy” when he talked about AI opportunities: “Nobody was interested.” This year, Jones said, he’s been “the belle of the ball.”

He called up his old business partner, and the two immediately spent about $550,000 securing the web domains for porn dot ai, deepfake dot com and deepfakes dot com, Jones said. “Lightspeed” was back.

One major model, Stable Diffusion, shares its code publicly, and some technologists have figured out how to edit the code to allow for sexual images

What keeps Jones up at night is people trying to use his company’s tools to generate images of abuse, he said. The models have some technological guardrails that make it difficult for users to render children, celebrities or acts of violence. But people are constantly looking for workarounds.

So with help from an angel investor he will not name, Jones hired five employees and a handful of offshore contractors and started building an image engine trained on bundles of freely available pornographic images, as well as thousands of nude photos from Jones’s own collection

Users create what Jones calls a “dream girl,” prompting the AI with descriptions of the character’s appearance, pose and setting. The nudes don’t portray real people, he said. Rather, the goal is to re-create a fantasy from the user’s imagination.

The AI-generated images got better, their computerized sheen growing steadily less noticeable. Jones grew his user base to 500,000 people, many of whom pay to generate more images than the five per day allotted to free accounts, he said. The site’s “power users” generate AI porn for 10 hours a day, he said.

Jones described the site as an “artists’ community” where people can explore their sexualities and fantasies in a safe space. Unlike some corners of the traditional adult industry, no performers are being pressured, underpaid or placed in harm’s way

And critically, consumers don’t have to wait for their favorite OnlyFans performer to come online or trawl through Pornhub to find the content they like.

Next comes AI-generated video — “porn’s holy grail,” Jones said. Eventually, he sees the technology becoming interactive, with users giving instructions to lifelike automated “performers.” Within two years, he said, there will be “fully AI cam girls,” a reference to creators who make solo sex content.

It costs $12 per day to rent a server from Amazon Web Services, he said, and generating a single picture requires users to have access to a corresponding server. His users have so far generated more than 1.6 million images.

Copyright holders including newspapers, photographers and artists have filed a slew of lawsuits against AI companies, claiming the companies trained their models on copyrighted content. If plaintiffs win, it could cut off the free-for-all that benefits entrepreneurs such as Jones.

But Jones’s plan to create consumer-friendly AI porn engines faced significant obstacles. The companies behind major image-generation models used technical boundaries to block “not safe for work” content and, without racy images to learn from, the models weren’t good at re-creating nude bodies or scenes.

Jones said his team takes down images that other users flag as abusive. Their list of blocked prompts currently contains 1,000 terms including “high school.”

“I see certain things people type in, and I just hope to God they’re trying to test the model, like we are. I hope they don’t actually want to see the things they’re typing in.

Peter Acworth, the owner of kink dot com, is trying to teach an AI porn generator to understand even subtler concepts, such as the difference between torture and consensual sexual bondage. For decades Acworth has pushed for spaces — in the real world and online — for consenting adults to explore nonconventional sexual interests. In 2006, he bought the San Francisco Armory, a castle-like building in the city’s Mission neighborhood, and turned it into a studio where his company filmed fetish porn until shuttering in 2017.

Now, Acworth is working with engineers to train an image-generation model on pictures of BDSM, an acronym for bondage and discipline, dominance and submission, sadism and masochism.

Others alluded to a porn apocalypse, with AI wiping out existing models of adult entertainment.“Look around,” said Christian Burke, head of engineering at the adult-industry payment app Melon, gesturing at performers huddled, laughing and hugging across the show floor. “This could look entirely different in a few years.”

But the age of AI brings few guarantees for the people, largely women, who appear in porn. Many have signed broad contracts granting companies the rights to reproduce their likeness in any medium for the rest of time

Not only could performers lose income, Walters said, they could find themselves in offensive or abusive scenes they never consented to.

Lana Smalls, a 23-year-old performer whose videos have been viewed 20 million times on Pornhub, said she’s had colleagues show up to shoots with major studios only to be surprised by sweeping AI clauses in their contracts.

“This industry is too fragmented for collective bargaining,” Spiegler said. “Plus, this industry doesn’t like rules.”

A glimmer of hope for Biden emerged toward the end of the survey: “If Donald Trump is found guilty and convicted this year of a felony — with Donald Trump as the Republican candidate and Joe Biden as the Democratic candidate — for whom would you vote?”In this hypothetical circumstance, Biden pulls ahead of Trump, 45-43.

when asked, “How willing would you be to vote for Donald Trump if he is convicted of a crime?” 53 percent of registered voters surveyed said they would be “unwilling” to do so; 46 percent said “very unwilling”; and 7 percent said “somewhat unwilling.”

Bloomberg-Morning Consult asked respondents whether they would be unwilling to vote for Trump if he were “sentenced to prison”: 55 percent said unwilling, 48 percent very unwilling and 7 percent said somewhat unwilling.

YouGov found that 45 percent of respondents were either unaware of or uncertain that Trump had “been charged with falsifying business records to conceal hush money payments to Stormy Daniels, a porn star” and that Trump “had been found liable for sexually assaulting and defaming writer E. Jean Carroll.”

The most recent NBC News poll, conducted at the end of January, has Trump favored over Biden by a substantial 47 percent to 42 percent.

In the RealClearPolitics compilation of polls that add Robert Kennedy Jr., Cornel West and Jill Stein to the mix, Trump’s lead over Biden more than doubles, to 4.8 points, 41.6 to 36.8 percent. Kennedy gets 13 percent, and West and Stein each get 2.1 percent.

Along with the threat posed by third-party candidates, two major crises — immigration and the Israeli assault on Hamas in Gaza — have become significant liabilities for the Biden campaign.

The Dec. 10-14 New York Times/Siena poll found that young voters, aged 18 to 29, favored Trump over Biden 49-43. These voters said they trusted Trump over Biden “to do a better job on the Israeli-Palestinian conflict” 49-30. In the 2020 election, Biden beat Trump among 18-to-29-year-old voters by 24 points, 60-36, according to exit polls, by far his biggest margin in all age groups.

“To win in 2024, Biden will need to convince voters that he is still the proud moderate they voted for in 2020,” Cowan wrote by email. “He has a lot of evidence on his side, but he still has a lot of convincing to do.”

Biden’s showing “middle- and working-class voters that he understands their values and takes seriously their concerns around crime, immigration and the economy — which, as polling makes clear, are often dramatically different and far more mainstream and centrist than those of college-educated elites who staff much of Washington — is the only way to win.”

While bitterly criticized by many liberals, the Supreme Court decision last year to ban affirmative action in public and private colleges will in fact reduce the salience of an issue that has historically worked to build support for Republicans.

Rising inflation has led to surging prices for groceries, cars and many essentials. The cost of a college education has skyrocketed in two decades, with the average student debt for federal loans at $37,000, according to the Education Department. Overall debts for Americans in their 30s jumped 27% from late 2019 to early 2023—steeper than for any other age group.

home prices have risen considerably, while wages haven’t kept pace.

“What Dave Ramsey really misses is any kind of social context,” says Morgan Sanner, a

She began paying off $48,000 in student loans (a Ramsey do) and also took out a loan to buy a 2016 Honda (a Ramsey don’t). Her rationale was that it was safer to pay extra for a more reliable car than a junker she could buy with cash. S

he feels these sorts of real-life decisions don’t factor into his advice.

When she saw a comment from Ramsey online about how people receiving pandemic stimulus payments were “pretty much screwed already,” Israel felt it came across as shaming people. The pandemic shutdowns ended a decadelong economic expansion for Black Americans, a disproportionate number of whom lost their jobs and relied on those checks.

“Moralizing financial decisions is very damaging to marginalized groups,” says Israel, who is Black.

Many young adults scratch their heads over his advice that people should let their credit scores dwindle and die.

People need a good credit score, says Mandy Phillips, a 39-year-old residential mortgage loan originator in Redding, Calif. She uses TikTok and other social media to educate millennials and Gen Z about home buying. Scores are vital when applying for mortgages and rentals.

She also takes issue with Ramsey’s advice to only obtain a home loan if you can take out a 15-year fixed-rate mortgage with a down payment of at least 10%. Few younger buyers can pay the large monthly bills of shorter-term mortgages.

“That may have worked years ago in the ’80s and ’90s, but that’s not something that is achievable for the average American,” Phillips says.

Housing is a particularly hot-button topic. He advises people to only buy a house with their lawfully wedded spouse. Yet many young adults are pooling their finances with partners, friends or roommates to buy their first homes. 

Ramsey is perhaps best known for advocating a “debt snowball method”: People with multiple loans pay off the smallest balances first, regardless of interest rate. As you knock out each loan, he says, the money you have to put toward larger debt snowballs. Seeing small wins motivates people to keep going, he says.Conventional economic theory would be to pay off the highest-interest loans first, says James Choi, a finance professor at the Yale School of Management, who has studied the advice of popular finance gurus.

Ramsey’s save-not-spend message sounds logical, young adults say. It’s his all-or-nothing approach that doesn’t work for them.

Kate Hindman, a 31-year-old administrative assistant in Pasadena, Calif., who has taken an anti-Ramsey stance on TikTok, ended up with $30,000 in credit-card debt after she and her husband faced income-reducing job changes. They’ve since turned it into a consolidation loan with an 8% interest rate and pay about $1,200 a month.

She wonders if the debt aversion is generational. Perhaps younger people are less willing to make huge sacrifices to be debt-free. Maybe carrying some amount of debt forever is a new normal.

after Mr. Trump won the election that year, the world seemed to blame tech companies for his victory. The resulting “techlash” against Facebook and others caused some industry leaders to reassess their political views, a trend that continued through the social and political turmoil of the pandemic.

The start-up industry has also been in a downturn since 2022, with higher interest rates sending capital fleeing from risky bets and a dismal market for initial public offerings crimping opportunities for investors to cash in on their valuable investments.

Some investors said they were frustrated that his pick for chair of the Federal Trade Commission, Lina Khan, has aggressively moved to block acquisitions, one of the main ways venture capitalists make money. They said they were also unhappy that Mr. Biden’s pick for head of the Securities and Exchange Commission, Gary Gensler, had been hostile to cryptocurrency companies.

Last month, Mr. Sacks, Mr. Thiel, Elon Musk and other prominent investors attended an “anti-Biden” dinner in Hollywood, where attendees discussed fund-raising and ways to oppose Democrats,

Some also said they disliked Mr. Biden’s proposal in March to raise taxes, including a 25 percent “billionaire tax” on certain holdings that could include start-up stock, as well as a higher tax rate on profits from successful investments.

“If you keep telling someone over and over that they’re evil, they’re eventually not going to like that,” he said. “I see that in venture capital.”

Some tech investors are also fuming over how Mr. Biden has handled foreign affairs and other issues.

Mr. Andreessen, a founder of Andreessen Horowitz, a prominent Silicon Valley venture firm, said in a recent podcast that “there are real issues with the Biden administration.” Under Mr. Trump, he said, the S.E.C. and F.T.C. would be headed by “very different kinds of people.” But a Trump presidency would not necessarily be a “clean win” either, he added.

Mr. Sacks said at the tech conference last week that he thought such taxes could kill the start-up industry’s system of offering stock options to founders and employees. “It’s a good reason for Silicon Valley to think really hard about who it wants to vote for,” he said.

“Tech, venture capital and Silicon Valley are looking at the current state of affairs and saying, ‘I’m not happy with either of those options,’” he said. “‘I can no longer count on Democrats to support tech issues, and I can no longer count on Republicans to support business issues.’”

Ben Horowitz, a founder of Andreessen Horowitz, wrote in a blog post last year that the firm would back any politician who supported “an optimistic technology-enabled future” and oppose any who did not. Andreessen Horowitz has donated $22 million to Fairshake, a political action group focused on supporting crypto-friendly lawmakers.

Venture investors are also networking with lawmakers in Washington at events like the Hill & Valley conference in March, organized by Jacob Helberg, an adviser to Palantir, a tech company co-founded by Mr. Thiel. At that event, tech executives and investors lobbied lawmakers against A.I. regulations and asked for more government spending to support the technology’s development in the United States.

This month, Mr. Helberg, who is married to Mr. Rabois, donated $1 million to the Trump campaign

In his 2007 history of the movement, Radicals for Capitalism, Brian Doherty identifies five key figures who most shaped the nascent ideology and its organized advocacy: author Ayn Rand, and economists Ludwig von Mises, F. A. Hayek, Milton Friedman, and Murray Rothbard

With one exception, all paired radical free-market and smaller government views with liberal tolerance and cosmopolitanism on social issues. None were religious, and Rand and Mises were both avowedly irreligious. Friedman and Hayek both trended more moderate and pragmatic, and also achieved the highest degree of mainstream intellectual recognitio

It was in Rothbard that the divergence began which today has culminated in the Libertarian Party’s convention transforming into a literal Trump rally

He was in many ways the most radical—an avowed anarchist—and the most marginal

he was also the most involved in creating a self-consciously libertarian movement and many of its institutions. In this he was aided by his skills as a prolific polemicist.

From the start, Trump’s brand of illiberal populism had more than a passing resemblance to Rothbard’s paleo strategy—minus, as many classical liberal critics had long predicted, any meaningful moves to actually shrink government

By accommodating and embracing conservative culture warriors, even including avowed white supremacists, Rothbard believed he was forming the basis of a political coalition to demolish modern big government

it included an open embrace of police brutality, fuming about the need to “dispense instant punishment” to “bums,” while railing against efforts to undo America’s white supremacist past. Later, opposition to immigration became one of the paleo posture’s signature issues.

Across the loose constellation of libertarian think tanks, advocacy organizations, and electoral efforts in both the L.P. and the GOP, the embrace or rejection of Rothbard’s “paleo” idea was a source of perennial tension. Rothbard himself was involved for a time in both the Libertarian Party and the Cato Institute, co-founding the latter before being acrimoniously ejected after a few years.

the other end of the movement came to embrace the view of libertarianism as fundamentally an extension of the larger liberal tradition, continuous with a classical liberal political philosophy rather than a socially conservative one.

Free markets and limited government were still a big part of the picture, but in service to a vision of a dynamic and pluralistic free society.

As much as each held a dim view of the other, both continued to work under the “libertarian” label.

As he outlined in a 1992 essay, “Right Wing Populism: A Strategy for the Paleo Movement,” paleolibertarianism was an explicit alliance between small-government radicalism and the extremist far-right.

it still embodied the burn-it-all-down reactionary ethos that saw tearing down established institutions as a necessary first step, even if that required an unrestrained autocrat

After the deadly 2017 neo-Nazi rally in Charlottesville, the then party leadership denounced the “blood and soil” rhetoric. But to the Rothbardians, this smacked of unacceptable wokeness. Within a few days, the Mises Caucus—named more for the ideas exhibited by the think-tank than the actual economist—was founded. Over the next few years, this group began launching hostile takeovers of state parties and then the national party. As they did so, the party increasingly adopted rhetoric that sounded more like the tiki-torch brigade than one committed to individual liberty.

The two camps within the movement—the cosmopolitan and the paleo—already strained to nearly the breaking point, went through the inevitable rupture. A number of differences and disagreements fueled the split, but most central was the divide into MAGA-friendly and anti-Trump sympathies.

It is no longer possible to ignore the conflict of visions about what kind of society freedom was supposed to yield. One in which private bigotry and established hierarchies were allowed free rein? Or an open and all-embracing one where different people and lifestyles disapproved by the traditional order could flourish?

The only way the libertarian movement’s demise could bring down libertarianism as a political-philosophical framework is if one expected the ideas themselves to disappear. Happily, a robust conviction of the centrality of individual liberty—or of the need to fight a tyrannical state—is in no danger of fully fading away.

But these stores exercise an outsize impact, she said, as they di

more than any restaurant, cookbook or online video, Asian grocers are driving this shift.

April 2023 to April 2024, sales of items in the “Asian/ethnic aisle” in U.S. grocery stores grew nearly four times more than overall sales

Miso, ghee, turmeric, soy sauce — their journeys to becoming widely available pantry staples all began with an Asian grocer.

H Mart is attracting the clientele of the big grocers, too. Thirty percent of its shoppers today are non Asian, Mr. Kwon said, and he’s made changes to continue drawing them

placing more emphasis on in-store tastings, explaining how ingredients are used and posting signs in both Korean and English. Similarly, at 99 Ranch, the announcements ring out in Mandarin and English, and Western music has been added to the store playlists.

Swetal Patel, a partner at Patel Brothers, said that as the chain has expanded its audience — he estimates that 20 to 25 percent of shoppers are now non South Asian

“I find it fascinating that there are things on the shelf that I have no idea what they are,” said Jill Connors, an economic development director for the city of Dubuque, Iowa, who started shopping at Hornbill Asian Market earlier this year because she and her husband became vegan and wanted high-quality tofu at a reasonable price.

The sheer variety of foods to explore “brings more joy to the shopping and cooking process,”

The roots of this phenomenon have been well studied. They include the cultural aggression of elite institutions and the predictable reaction to it, the nationalization of issues abetted by the collapse of local media and the pernicious effects of the antisocial media.

The gerrymandering that once exaggerated a dominant party’s political margin is no longer much of a factor; social clustering and these other factors have often done a more effective job than the political bosses ever did. In many jurisdictions today, one would have to reverse gerrymander, mixing geographies and crossing all kinds of legal boundary lines, to produce a truly competitive electorate.

Our campaign messages, as they had to, mostly centered on specific, new ideas: ethics reforms, access to health insurance, property tax caps, automatic tax refunds and many more, all couched in rhetoric stressing Indianans’ commonality as people, and the need for every part of the state to participate fully in its better future. Boy, is that passé.

Ideas fashioned not to stroke the erogenous zones of a riled-up minority of left or right, but to speak to the broader public in pursuit of a general election victory, evoke our common interest instead of our differences and antagonisms. But such campaigns rarely make sense these days.

Political campaigns need not necessarily be dispiriting, narrowcasting mudfests. They can be vehicles, in fact the best possible vehicles, for floating constructive ideas to an attentive public. Ideas proposed by a successful campaign have a higher likelihood of enactment after the election

Once in office, to make effective change, we had to engage with our Democratic counterparts, even in the years when we achieved full but narrow legislative control.

In 2024, 30 states feature not only trifecta government but 2-to-1 majorities in at least one house. In that setting, both campaigns and governance look totally different than they do in genuine two-party polities.

This year, our next governor ran a smart race and won his victory fair and square. The problem is that neither he, nor any of his competitors, had an incentive to offer their soon-to-be employers a sense of how Indiana could move forward.

What voters saw instead, besides attacks on each other, were political advertisements centered on “standing up to China,” taking on foreign drug cartels and closing the Mexican border. It became difficult to tell whether these folks were running for secretary of state or secretary of homeland security.

Wise policy and good government can and do emerge in lopsided states. But competition, always and everywhere, fosters innovation. In politics, it also compels a sensitivity and an outreach to the widest possible audiences.

The contours of the current system don’t conduce to those outcomes; until that changes, we have to hope for candidates who, elected by 5 percent of the state, somehow come to consider their duty of service to all the rest.

In fact, the news from Wall Street lately has mostly been about retreat from climate goals, rather than recommitment. Banks and asset managers are withdrawing from international climate alliances and chafing at their rules. Regional banks are stepping up lending to fossil fuel producers. Sustainable investment funds have sustained crippling outflows, and many have collapsed.

In some cases, it’s a classic prisoner’s dilemma: If firms collectively shift to cleaner energy, a cooler climate benefits everyone more in the future

in the short term, each firm has an individual incentive to cash in on fossil fuels, making the transition much harder to achieve.

when it comes to avoiding climate damage to their own operations, the financial industry is genuinely struggling to comprehend what a warming future will mean.

A global compact of financial institutions made commitments worth $130 trillion to try to bring down emissions, confident that governments would create a regulatory and financial infrastructure to make those investments profitable. And in 2022, the Inflation Reduction Act passed.

What about the risk that climate change poses to the financial industry’s own investments, through more powerful hurricanes, heat waves that knock out power grids, wildfires that wipe out towns?

“If we think about what is going to be the best way to tilt your portfolios in the direction to benefit, it’s really difficult to do,”

“These will probably be great investments over 20 years, but when we’re judged over one to three years, it’s a little more challenging for us.”

Some firms cater to institutional clients, like public employee pension funds, that want combating climate change to be part of their investment strategy and are willing to take a short-term hit. But they aren’t a majority

And over the past couple of years, many banks and asset managers have shrunk from anything with a climate label for fear of losing business from states that frown on such concerns.

On top of that, the war in Ukraine scrambled the financial case for backing a rapid energy transition. Artificial intelligence and the movement toward greater electrification are adding demand for power, and renewables haven’t kept up

All of that is about the relative appeal of investments that would slow climate change

If you bought some of the largest solar-energy exchange-traded funds in early 2023, you would have lost about 20 percent of your money, while the rest of the stock market soared.

There is evidence that banks and investors price in some physical risk, but also that much of it still lurks, unheeded.

“I’m very, very worried about this, because insurance markets are this opaque weak link,” Dr. Sastry said. “There are parallels to some of the complex linkages that happened in 2008, where there is a weak and unregulated market that spills over to the banking system.”

Regulators worry that failing to understand those ripple effects could not just put a single bank in trouble but even become a contagion that would undermine the financial system.

But while the European Central Bank has made climate risk a consideration in its policy and oversight, the Federal Reserve has resisted taking a more active role, despite indications that extreme weather is feeding inflation and that high interest rates are slowing the transition to clean energy.

“The argument has been, ‘Unless we can convincingly show it’s part of our mandate, Congress should deal with it, it’s none of our business,’”

a much nearer-term uncertainty looms: the outcome of the U.S. election, which could determine whether further action is taken to address climate concerns or existing efforts are rolled back. An aggressive climate strategy might not fare as well during a second Trump administration, so it may seem wise to wait and see how it shakes out.

big companies are hesitating on climate-sensitive investments as November approaches, but says that “two things are misguided and quite dangerous about that hypothesis.”

One: States like California are establishing stricter rules for carbon-related financial disclosures and may step it up further if Republicans win

And two: Europe is phasing in a “carbon border adjustment mechanism,” which will punish polluting companies that want to do business there.

at the moment, even European financial institutions feel pressure from the United States, which — while providing some of the most generous subsidies so far for renewable-energy investment — has not imposed a price on carbon.

The global insurance company Allianz has set out a plan to align its investments in a way that would prevent warming above 1.5 degrees Celsius by the end of the century, if everyone else did the same. But it’s difficult to steer a portfolio to climate-friendly assets while other funds take on polluting companies and reap short-term profits for impatient clients.

“This is the main challenge for an asset manager, to really bring the customer along,” said Markus Zimmer, an Allianz economist. Asset managers don’t have sufficient tools on their own to move money out of polluting investments and into clean ones, if they want to stay in business,

“Of course it helps if the financial industry is somehow ambitious, but you cannot really substitute the lack of actions by policymakers,”

According to new research, the benefit is greater when decarbonization occurs faster, because the risks of extreme damage mount as time goes on. But without a uniform set of rules, someone is bound to scoop up the immediate profits, disadvantaging those that don’t — and the longer-term outcome is adverse for all.

As a young State Department policy planner in the 2000s, she was a lonely voice in Washington raising the alarm about the rise of China. She pushed for tariffs and against trade agreements before it was cool, and was an author of a book called “War by Other Means” about how blind faith in free markets put the United States at a geopolitical disadvantage. For years, she felt like an oddball in Washington, where both parties were still in thrall to neoliberalism.

The Hewlett Foundation hired her as the head of an initiative that has given away $140 million so far to people who are devising a new economic philosophy. Then she served a stint in the White House. Today, she’s an intellectual leader of a growing, bipartisan consensus

She fell in love with economics and studied it at Wake Forest. After she joined a student delegation to a NATO summit in Prague in 2002, a faculty adviser on that trip offered her a job in Washington working at the National Intelligence Council. In those early years, she believed what everyone else in Washington believed about the economy — that governments ought not meddle with it.

if Mr. Trump correctly identified a problem — “China is eating our lunch” — he did not solve it, beyond putting tariffs on Chinese products. His tax cut for the rich hurt rather than helped matters.

It’s the Biden administration that came in with a plan to build an economy that was good for workers, not just shareholders, using some strategies Ms. Harris had been talking about for years.

The thinking behind it goes like this: Unquestioning belief in the free market created a globalism that funneled money to the 1 percent, which has used its wealth to amass political power at the expense of everyone else. It produced free trade agreements that sent too many U.S. factories to China and rescue plans after the 2008 financial crisis that bailed out Wall Street instead of Main Street.

It was her job to track China’s use of subsidies, industrial espionage and currency manipulation to fuel its rise as a manufacturing powerhouse. Ms. Harris argued that tariffs on China were a necessary defense. Nobody agreed. “I was kind of just banging my head against this wall,” she told me. “The wall was a foreign policy establishment that saw markets as sacrosanct.”

Barack Obama campaigned on a pledge to renegotiate NAFTA, but he struck up a new trade deal instead — the Trans-Pacific Partnership. Ms. Harris argued against it. “We didn’t have the foggiest idea” of what it would do to our economy, she told me. Nobody listened.

it sent Democrats back to the intellectual drawing board. Larry Kramer, then the president of the Hewlett Foundation, recruited her in 2018 to promote alternatives to ideas that had guided U.S. policy for decades. He hoped she could do for free-market skepticism what Milton Friedman and his allies had done for free-market fundamentalism, which became policy under the Reagan administration and eventually was embraced by both parties as truth.

She has since rejoined the Hewlett Foundation, where she funds people who are proposing new solutions to economic problems. One grantee, the conservative think tank American Compass, promotes the idea of a domestic development bank to fund infrastructure — an idea with bipartisan appeal.

But the work that Ms. Harris and others in the Biden administration have done is unfinished, and poorly understood. The terms “Bidenomics” and “Build Back Better” don’t seem to resonate

Ms. Harris acknowledges that these ideas haven’t yet taken hold in the broader electorate, and that high interest rates overshadow the progress that’s been made. It’s too early for voters to feel it, she told me: “The investments Biden has pushed through aren’t going to be felt in a month, a year, two years.”

she celebrates the fact that leaders across the political spectrum are embracing the idea that Americans need to “get back to building things in this country.” This election has no candidates blindly promoting the free market. The last one didn’t either. In the battle of ideas, she has already won.

“Over 80 technical papers published since January 2022,” LeCun responded. “What about you?”

To which Musk posted: “That’s nothing, you’re going soft. Try harder!

At stake are the hearts and minds of AI experts—academic and otherwise—needed to usher in the technology

“Join xAI,” LeCun wrote, “if you can stand a boss who:– claims that what you are working on will be solved next year (no pressure).– claims that what you are working on will kill everyone and must be stopped or paused (yay, vacation for 6 months!).– claims to want a ‘maximally rigorous pursuit of the truth’ but spews crazy-ass conspiracy theories on his own social platform.”

Some read Musk’s “science” dig as dismissing the role research has played for a generation of AI experts. For years, the Metas and Googles of the world have hired the top minds in AI from universities, indulging their desires to keep a foot in both worlds by allowing them to release their research publicly, while also trying to deploy products. 

For an academic such as LeCun, published research, whether peer-reviewed or not, allowed ideas to flourish and reputations to be built, which in turn helped build stars in the system.

LeCun has been at Meta since 2013 while serving as an NYU professor since 2003. His tweets suggest he subscribes to the philosophy that one’s work needs to be published—put through the rigors of being shown to be correct and reproducible—to really be considered science. 

“If you do research and don’t publish, it’s not Science,” he posted in a lengthy tweet Tuesday rebutting Musk. “If you never published your research but somehow developed it into a product, you might die rich,” he concluded. “But you’ll still be a bit bitter and largely forgotten.” 

After pushback, he later clarified in another post: “What I *AM* saying is that science progresses through the collision of ideas, verification, analysis, reproduction, and improvements. If you don’t publish your research *in some way* your research will likely have no impact.”

The spat inspired debate throughout the scientific community. “What is science?” Nature, a scientific journal, asked in a headline about the dust-up.

Others, such as Palmer Luckey, a former Facebook executive and founder of Anduril Industries, a defense startup, took issue with LeCun’s definition of science. “The extreme arrogance and elitism is what people have a problem with,” he tweeted.

For Musk, who prides himself on his physics-based viewpoint and likes to tout how he once aspired to work at a particle accelerator in pursuit of the universe’s big questions, LeCun’s definition of science might sound too ivory-tower. 

Musk has blamed universities for helping promote what he sees as overly liberal thinking and other symptoms of what he calls the Woke Mind Virus. 

Over the years, an appeal of working for Musk has been the impression that his companies move quickly, filled with engineers attracted to tackling hard problems and seeing their ideas put into practice.

“I’ve teamed up with Elon to see if we can actually apply these new technologies to really make a dent in our understanding of the universe,” Igor Babuschkin, an AI expert who worked at OpenAI and Google’s DeepMind, said last year as part of announcing xAI’s mission. 

The creation of xAI quickly sent ripples through the AI labor market, with one rival complaining it was hard to compete for potential candidates attracted to Musk and his reputation for creating value

that was before xAI’s latest round raised billions of dollars, putting its valuation at $24 billion, kicking off a new recruiting drive. 

It was already a seller’s market for AI talent, with estimates that there might be only a couple hundred people out there qualified to deal with certain pressing challenges in the industry and that top candidates can easily earn compensation packages worth $1 million or more

Since the launch, Musk has been quick to criticize competitors for what he perceived as liberal biases in rival AI chatbots. His pitch of xAI being the anti-woke bastion seems to have worked to attract some like-minded engineers.

As for Musk’s final response to LeCun’s defense of research, he posted a meme featuring Pepé Le Pew that read: “my honest reaction.”

They also claim that OpenAI has used hardball tactics to prevent workers from voicing their concerns about the technology, including restrictive nondisparagement agreements that departing employees were asked to sign.

“OpenAI is really excited about building A.G.I., and they are recklessly racing to be the first there,” said Daniel Kokotajlo, a former researcher in OpenAI’s governance division and one of the group’s organizers.

Other members include William Saunders, a research engineer who left OpenAI in February, and three other former OpenAI employees: Carroll Wainwright, Jacob Hilton and Daniel Ziegler. Several current OpenAI employees endorsed the letter anonymously because they feared retaliation from the company,

At OpenAI, Mr. Kokotajlo saw that even though the company had safety protocols in place — including a joint effort with Microsoft known as the “deployment safety board,” which was supposed to review new models for major risks before they were publicly released — they rarely seemed to slow anything down.

So was the departure of Dr. Leike, who along with Dr. Sutskever had led OpenAI’s “superalignment” team, which focused on managing the risks of powerful A.I. models. In a series of public posts announcing his departure, Dr. Leike said he believed that “safety culture and processes have taken a back seat to shiny products.”

“When I signed up for OpenAI, I did not sign up for this attitude of ‘Let’s put things out into the world and see what happens and fix them afterward,’” Mr. Saunders said.

Mr. Kokotajlo, 31, joined OpenAI in 2022 as a governance researcher and was asked to forecast A.I. progress. He was not, to put it mildly, optimistic.In his previous job at an A.I. safety organization, he predicted that A.G.I. might arrive in 2050. But after seeing how quickly A.I. was improving, he shortened his timelines. Now he believes there is a 50 percent chance that A.G.I. will arrive by 2027 — in just three years.

He also believes that the probability that advanced A.I. will destroy or catastrophically harm humanity — a grim statistic often shortened to “p(doom)” in A.I. circles — is 70 percent.

Last month, two senior A.I. researchers — Ilya Sutskever and Jan Leike — left OpenAI under a cloud. Dr. Sutskever, who had been on OpenAI’s board and voted to fire Mr. Altman, had raised alarms about the potential risks of powerful A.I. systems. His departure was seen by some safety-minded employees as a setback.

Mr. Kokotajlo said, he became so worried that, last year, he told Mr. Altman that the company should “pivot to safety” and spend more time and resources guarding against A.I.’s risks rather than charging ahead to improve its models. He said that Mr. Altman had claimed to agree with him, but that nothing much changed.

In April, he quit. In an email to his team, he said he was leaving because he had “lost confidence that OpenAI will behave responsibly" as its systems approach human-level intelligence.

“The world isn’t ready, and we aren’t ready,” Mr. Kokotajlo wrote. “And I’m concerned we are rushing forward regardless and rationalizing our actions.”

On his way out, Mr. Kokotajlo refused to sign OpenAI’s standard paperwork for departing employees, which included a strict nondisparagement clause barring them from saying negative things about the company, or else risk having their vested equity taken away.

Many employees could lose out on millions of dollars if they refused to sign. Mr. Kokotajlo’s vested equity was worth roughly $1.7 million, he said, which amounted to the vast majority of his net worth, and he was prepared to forfeit all of it.

Mr. Altman said he was “genuinely embarrassed” not to have known about the agreements, and the company said it would remove nondisparagement clauses from its standard paperwork and release former employees from their agreements.)

In their open letter, Mr. Kokotajlo and the other former OpenAI employees call for an end to using nondisparagement and nondisclosure agreements at OpenAI and other A.I. companies.

“Broad confidentiality agreements block us from voicing our concerns, except to the very companies that may be failing to address these issues,”

They also call for A.I. companies to “support a culture of open criticism” and establish a reporting process for employees to anonymously raise safety-related concerns.

They have retained a pro bono lawyer, Lawrence Lessig, the prominent legal scholar and activist

Mr. Kokotajlo and his group are skeptical that self-regulation alone will be enough to prepare for a world with more powerful A.I. systems. So they are calling for lawmakers to regulate the industry, too.

“There needs to be some sort of democratically accountable, transparent governance structure in charge of this process," Mr. Kokotajlo said. “Instead of just a couple of different private companies racing with each other, and keeping it all secret.”

A lot of the news, however, is bad.

The bad news includes examples of people who reacted to Saturday’s events by glorifying violence, or by mocking its victims

The abject tactical failures of the Secret Service pose structural questions that urgently need to be answered.

The first conspiracies came from Trump’s detractors. As soon as the first pictures of his injury emerged, some influential Democratic activists and advisors suggested that this was a false flag operation, designed to strengthen his appeal.

Biden has, for example, repeatedly claimed that he decided to enter the 2020 presidential race after hearing Trump referring to the neo-Nazis and white supremacists who assembled for a deadly rally in Charlottesville in 2017 as “very fine people.” But while Trump was characteristically meandering and irresponsible in his remarks after that rally, he explicitly stated that “I'm not talking about the neo-Nazis and the white nationalists, because they should be condemned totally.”

Parts of the left have justified some forms of violence in the last years. Movements like Antifa explicitly glorify political violence, reserving for themselves both the right to take action against anyone they consider fascist, and the right to determine who should be included in that category

All of this is shameful. It must be called out and condemned without hedging or special pleading. But it also shouldn’t be inflated to imply that the Democratic establishment or the mainstream media has in general started to glorify violence.

Conversely, there is no doubt that parts of the Republican Party and the conservative movement have glorified political violence in the last years.

All of this is shameful, all the more so for coming from the most senior officials within the Republican Party. All of this must be called out and condemned without hedging or special pleading, something that the conservative media ecosystem have notably failed to do.

no excuse for overstating the extent to which the other side embraces political violence. And that is something that the most senior Democrats, from Joe Biden on down, have consistently done.

But the extent of conspiracism was much worse on the right.

he question of the day has come to be whether it is appropriate to portray Trump as an existential threat to democracy.

If it was appropriate to resist Hitler by violent means, and Trump is his modern-day equivalent, then (so goes the tacit implication of the New Republic’s cover), why shouldn’t it be legitimate to resist Trump by violent means?

Depressingly often, in American politics, both sides are badly wrong. In this particular case, it seems to me that both sides are mostly right.

It is perfectly appropriate—even in the aftermath of Saturday’s unconscionable attack on Trump—to warn about what his presidency may mean for America’s democracy. But there is never an excuse—even and especially when the stakes are truly high—for fear-mongering that distorts the exact nature of that threat.

if moments of tragedy and upheaval reveal the true state of a country, the first draft of America’s report card puts it in danger of failing. Most Americans continue to abhor violence. Our mutual hatred still knows limits. And yet the mix of institutional failure, conspiracist thinking, and partisan fear-mongering is very potent. The risk that it may yet set in motion dynamics which overwhelm the decent instincts of most ordinary Americans remains very real

As a history teacher in a large, diverse suburban high school, I have spent more and more time in recent years trying (with mixed results) to "win back" white boys falling down dark internet rabbit holes of racist, Islamophobic and antisemitic conspiracy theories, misogyny, etc. Most of these boys of course do not end up as shooters (when I suspect that might be the case I go right to administration), but they do end up holding horrifying views that bode ill for the future of our polity.

What defies the typical "shooter" stereotype among most in this larger universe of white boys getting radicalized online is that most, though not all, of the latter (in my experience) are among my most intellectually curious, thoughtful and sensitive students. But, to use Professor Henderson's phraseology, they are not "alphas." Some have friends, even girlfriends, but none of them are part of the "popular" crowd. They are bright, but not "good at school" like the students who end up in your Ivy League courses. At 15 or 16 or 17, they feel (correctly) that they have something to offer the world, but feel they have been locked out of all the paths to success in their narrow world: They'll never be star athletes, or valedictorian, or one of the popular kids.

They feel like the message we as a society (schools, YA literature, "mainstream media") are sending them is that "You are privileged; you are the oppressor, you are the cause and beneficiary of all the world's injustices." The complexities of graduate level political theory are generally lost on a teenage boy who feels like the whole world is against him. The irony is these are the boys who actually care about issues of justice. The quarterback and the debate champion don't care if you throw their privilege in their face. They know their worth and are too busy to care.

I am sharing this comment not so much to identify what motivates shooters - I have no expertise in criminal pathology - but more in terms of the educational vacuum creating a generation of disaffected young men open to believe conspiracy theories because we are no longer offering them an alternative narrative of Americanism that speak to them as powerfully as those of the conspiracy theorists, the White Nationalists, and the miraculously save man who will be their retribution.
