The fundamental geographic division in American politics has traditionally been a sectional conflict setting the North against the South. The idioms of "red states" and "blue states" caught on widely after the 2000 presidential election because they could be applied to a regional divide—blue North, red South—that was already presumed to reflect the main axis of political debate and competition. But the partisan difference between large-metro and rural residents has now become much larger than the gap between northerners and southerners.

I call this widening gap between the partisan loyalties of urban and rural America “the density divide.” Hopkins is clearly correct that urban vs. rural has eclipsed North vs. South as the geographic embodiment of our partisan divisions. As the old adage goes, a chart speaks a thousand white papers.

I suspect that battle between North and South lives on both culturally and geographically. The North has drifted out of the countryside and concentrated itself into our cities. At the same time, America’s rural and exurban counties have slowly become more and more homogenously Southern. The South has risen again … in rural Maine?

One of the puzzles of the 2016 election, and the catastrophe of the Trump presidency, is how populist white nationalism finally prevailed at a time when Americans, taken altogether, were less racist than ever

My hunch is that rural white culture, which was once regionally varied and distinctive, became more uniform by becoming increasingly Southern. I call this the Southernification thesis.

In the Density Divide, I argued that the key to answering “Why did white ethnonationalism finally work to win the GOP nomination and then the White House when it didn’t even get close to working for Pat Buchanan or Ron Paul?” was that residential self-selection on ethnicity, personality, and education had made lower density parts of the country progressively more homogenously ethnocentric and socially conservative, which finally made it possible to unify and organize rural and exurban whites as a single constituency.

I think it’s an incomplete explanation without something like the Southernification thesis. Before it could be successfully organized politically, America’s increasingly ethnocentric non-urban white population needed to be consolidated first through the adoption of a relatively uniform ethnocentric white culture.

When I was a kid, the Atlanta Bravesþff somehow became “America’s Team.” Could it be that the media mogul who married Hanoi Jane took the critical first step in bringing non-urban white America together by beaming sanitized Southern culture into living rooms everywhere?

For instance, when a Harvard scholar such as Steven Pinker speaks of “disempowering D.E.I.” as a necessary reform in American higher education, he’s not opposing diversity itself. Pinker is liberal, donates substantially to the Democratic Party and “loathes” Donald Trump. The objections he raises are shared by a substantial number of Americans across the political spectrum.

, the problem with D.E.I. isn’t with diversity, equity, or inclusion — all vital values.

First, it is a moral necessity for colleges to be concerned about hateful discourse, including hateful language directed at members of historically marginalized groups. Moreover, colleges that receive federal funds have a legal obligation

I’ll share with you three pervasive examples

In the name of D.E.I., all too many institutions have violated their constitutional commitments to free speech, due process and equal protection of the law.

Yet that is no justification for hundreds of universities to pass and maintain draconian speech codes on campus, creating a system of unconstitutional censorship that has been struck down again and again and again in federal court. Nor is it a justification for discriminating against faculty members for their political views or for compelling them to speak in support of D.E.I.

There is a better way to achieve greater diversity, equity, inclusion and related goals. Universities can welcome students from all walks of life without unlawfully censoring speech. They can respond to campus sexual violence without violating students’ rights to due process. They can diversify the student body without discriminating on the basis of race

Second, there is a moral imperative to respond to sexual misconduct on campus.

that is no justification for replacing one tilted playing field with another. Compelled in part by constitutionally problematic guidance from the Obama administration, hundreds of universities adopted sexual misconduct policies that strip the most basic due process protections from accused students. The result has been systematic injustice

The due process problem was so profound that in 2019 a state appellate court in California — hardly a bastion of right-wing jurisprudence — ruled that “fundamental fairness” entitles an accused student to cross-examine witnesses in front of a neutral adjudicator.

Third, it is urgently necessary to address racial disparities in campus admissions and faculty hiring — but, again, not at the expense of the Constitution.

it is difficult to ignore the overwhelming evidence that Harvard attempted to achieve greater diversity in part by systematically downranking Asian applicants on subjective grounds, judging them deficient in traits such as “positive personality,” likability, courage, kindness and being “widely respected.” That’s not inclusion; it’s discrimination.

Our nation has inflicted horrific injustices on vulnerable communities. And while the precise nature of the injustice has varied — whether it was slavery, Jim Crow, internment or the brutal conquest of Native American lands — there was always a consistent theme: the comprehensive denial of constitutional rights.

But one does not correct the consequences of those terrible constitutional violations by inflicting a new set of violations on different American communities in a different American era. A consistent defense of the Constitution is good for us all,

The danger posed by D.E.I. resides primarily not in these virtuous ends, but in the unconstitutional means chosen to advance them.

Virtuous goals should not be accomplished by illiberal means.

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

It’s dropping in developing countries, too. India surpassed China as the most populous country last year, yet its fertility is now below replacement.

“The demographic winter is coming,”

Smaller populations come with diminished global clout, raising questions in the U.S., China and Russia about their long-term standings as superpowers.

Some demographers think the world’s population could start shrinking within four decades—one of the few times it’s happened in history.

A year ago Japanese Prime Minister Fumio Kishida declared that the collapse of the country’s birthrate left it “standing on the verge of whether we can continue to function as a society.”

Had fertility stayed near 2.1, where it stood in 2007, the U.S. would have welcomed an estimated 10.6 million more babies since

In 2017, when the global fertility rate—a snapshot of how many babies a woman is expected to have over her lifetime—was 2.5, the United Nations thought it would slip to 2.4 in the late 2020s. Yet by 2021, the U.N. concluded, it was already down to 2.3—close to what demographers consider the global replacement rate of about 2.2

He has found that national birth registries are typically reporting births 10% to 20% below what the U.N. projected.

China reported 9 million births last year, 16% less than projected in the U.N.’s central scenario. In the U.S., 3.59 million babies were born last year, 4% less than the U.N. projected. In other countries, the undershoot is even larger: Egypt reported 17% fewer births last year. In 2022, Kenya reported 18% fewer.

In 2017 the U.N. projected world population, then 7.6 billion, would keep climbing to 11.2 billion in 2100. By 2022 it had lowered and brought forward the peak to 10.4 billion in the 2080s. That, too, is likely out of date

the University of Washington now thinks it will peak around 9.5 billion in 2061 then start declining. 

The falling birthrates come with huge implications for the way people live, how economies grow and the standings of the world’s superpowers.

In the U.S., a short-lived pandemic baby boomlet has reversed. The total fertility rate fell to 1.62 last year, according to provisional government figures, the lowest on record.

In 2017, when the fertility rate was 1.8, the Census Bureau projected it would converge over the long run to 2.0. It has since revised that down to 1.5. “It has snuck up on us,”

Historians refer to the decline in fertility that began in the 18th century in industrializing countries as the demographic transition. As lifespans lengthened and more children survived to adulthood, the impetus for bearing more children declined. As women became better educated and joined the workforce, they delayed marriage and childbirth, resulting in fewer children. 

Some demographers see this as part of a “second demographic transition,” a societywide reorientation toward individualism that puts less emphasis on marriage and parenthood, and makes fewer or no children more acceptable. 

In research published in 2021, the University of Maryland’s Kearney and two co-authors looked for possible explanations for the continued drop. They found that state-level differences in parental abortion notification laws, unemployment, Medicaid availability, housing costs, contraceptive usage, religiosity, child-care costs and student debt could explain almost none of the decline

“We suspect that this shift reflects broad societal changes that are hard to measure or quantify,” they conclude.

while raising children is no more expensive than before, parents’ preferences and perceived constraints have changed

“If people have a preference for spending time building a career, on leisure, relationships outside the home, that’s more likely to come in conflict with childbearing.” 

Once a low fertility cycle kicks in, it effectively resets a society’s norms and is thus hard to break, said Jackson. “The fewer children you see your colleagues and peers and neighbors having, it changes the whole social climate,”

Fertility is below replacement in India even though the country is still poor and many women don’t work—factors that usually sustain fertility.

Urbanization and the internet have given even women in traditional male-dominated villages a glimpse of societies where fewer children and a higher quality of life are the norm. “People are plugged into the global culture,

mothers and fathers, especially those that are highly educated, spend more time with their children than in the past. “The intensity of parenting is a constraint,”

Sub-Saharan Africa once appeared resistant to the global slide in fertility, but that too is changing. The share of all women of reproductive age using modern contraception grew from 17% in 2012 to 23% in 2022

Jose Rimon, a professor of public health at Johns Hopkins University, credits that to a push by national leaders in Africa which, he predicted, would drive fertility down faster than the U.N. projects. 

Mae Mariyam Thomas, 38, who lives in Mumbai and runs an audio production company, said she’s opted against having children because she never felt the tug of motherhood. She sees peers struggling to meet the right person, getting married later and, in some instances, divorcing before they have kids. At least three of her friends have frozen their eggs,

Danielle Vermeer grew up third in a family of four children on Chicago’s North Side, where her neighborhood was filled with Catholics of Italian, Irish and Polish descent and half her close friends had as many siblings as her or more.

Her Italian-American father was one of four children who produced 14 grandchildren. Now her parents have five grandchildren, including Vermeer’s two children, ages 4 and 7.

The 35-year-old, who is the co-founder of a fashion thrifting app, said that before setting out to have children, she consulted dozens of other couples and her Catholic church and read at least eight books on the subject, including one by Pope Paul VI. She and her husband settled on two as the right number.“The act of bringing a child into this world is an incredible responsibility,” she said.

Perhaps no country has been trying longer than Japan. After fertility fell to 1.5 in the early 1990s, the government rolled out a succession of plans that included parental leave and subsidized child care. Fertility kept falling.

In 2005, Kuniko Inoguchi was appointed the country’s first minister responsible for gender equality and birthrate. The main obstacle, she declared, was money: People couldn’t afford to get married or have children. Japan made hospital maternity care free and introduced a stipend paid upon birth of the child. 

Japan’s fertility rate climbed from 1.26 in 2005 to 1.45 in 2015. But then it started declining again, and in 2022 was back to 1.26.

This year, Prime Minister Fumio Kishida rolled out yet another program to increase births that extends monthly allowances to all children under 18 regardless of income, free college for families with three children, and fully paid parental leave.

noguchi, now a member of parliament’s upper house, said the constraint on would-be parents is no longer money, but time. She has pressed the government and businesses to adopt a four-day workweek

If you’re a government official or manager of a big corporation, you should not worry over questions of salary now, but that in 20 years time you will have no customers, no clients, no applicants to the Self-Defense Forces.”

Hungarian Prime Minister Viktor Orban has pushed one of Europe’s most ambitious natality agendas. Last year he expanded tax benefits for mothers so that women under the age of 30 who have a child are exempt from paying personal income tax for life. That’s on top of housing and child-care subsidies as well as generous maternity leaves. 

Hungary’s fertility rate, though still well below replacement, has risen since 2010. But the Vienna Institute of Demography attributed this primarily to women delaying childbirth because of a debt crisis that hit around 2010. Adjusted for that, fertility has risen only slightly, it concluded.

The usual prescription in advanced countries is more immigration, but that has two problems.

With no reversal in birthrates in sight, the attendant economic pressures are intensifying. Since the pandemic, labor shortages have become endemic throughout developed countries. That will only worsen in coming years as the postcrisis fall in birthrates yields an ever-shrinking inflow of young workers, placing more strain on healthcare and retirement systems.

worsening demographics could make this a second consecutive “lost decade” for global economic growth.

The Institute for Health Metrics and Evaluation found little evidence that pronatalist policies lead to sustained rebounds in fertility. A woman may get pregnant sooner to capture a baby bonus, researchers say, but likely won’t have more kids over the course of her lifetime.

As more countries confront stagnant population, immigration between them is a zero-sum gam

Historically, host countries have sought skilled migrants who enter through formal, legal channels, but recent inflows have been predominantly unskilled migrants often entering illegally and claiming asylum.

High levels of immigration have also historically aroused political resistance,

Many of the leaders keenest to raise birthrates are most resistant to immigratio

As birthrates fall, more regions and communities experience depopulation, with consequences ranging from closed schools to stagnant property values. Less selective colleges will soon struggle to fill classrooms because of the plunge in birthrates that began in 2007, said Fernández-Villaverde. Vance said rural hospitals can’t stay open because of the falling local population.

An economy with fewer children will struggle to finance pensions and healthcare for growing ranks of elderly. South Korea’s national pension fund, one of the world’s largest, is on track to be depleted by 2055

There’s been little public pressure to act, said Sok Chul Hong, an economist at Seoul National University. “The elderly are not very interested in pension reform, and the youth are apathetic towards politics,” he said. “It is truly an ironic situation.”

With consumers buying so little, at least relative to the Chinese economy’s productive capacity, how can the nation generate enough demand to keep that capacity in use? The main answer, as Michael Pettis points out, has been to promote extremely high rates of investment, more than 40 percent of G.D.P. The trouble is that it’s hard to invest that much money without running into severely diminishing returns.

financial repression — paying low interest on savings and making cheap loans to favored borrowers — that holds down household income and diverts it to government-controlled investment, a weak social safety net that causes families to accumulate savings to deal with possible emergencies, and more.

Part of the answer is bad leadership. President Xi Jinping is starting to look like a poor economic manager, whose propensity for arbitrary interventions — which is something autocrats tend to do — has stifled private initiative.

But China’s working-age population peaked around 2010 and has been declining ever since. While China has shown impressive technological capacity in some areas, its overall productivity also appears to be stagnating.

very high rates of investment may be sustainable if, like China in the early 2000s, you have a rapidly growing work force and high productivity growth as you catch up with Western economies

This, in short, isn’t a nation that can productively invest 40 percent of G.D.P. Something has to give.

the government was able to mask the problem of inadequate consumer spending for a number of years by promoting a gigantic real estate bubble. In fact, China’s real estate sector became insanely large by international standards.

what China must do seems straightforward: end financial repression and allow more of the economy’s income to flow through to households, and strengthen the social safety net so that consumers don’t feel the need to hoard cash. And as it does this it can ramp down its unsustainable investment spending.

But there are powerful players, especially state-owned enterprises, that benefit from financial repression

And when it comes to strengthening the safety net, the leader of this supposedly communist regime sounds a bit like the governor of Mississippi, denouncing “welfarism” that creates “lazy people.”

Japan ended up managing its downshifting well. It avoided mass unemployment, it never lost social and political cohesion, and real G.D.P. per working-age adult actually rose 50 percent over the next three decades, not far short of growth in the United States.

My great concern is that China may not respond nearly as well. How cohesive will China be in the face of economic trouble? Will it try to prop up its economy with an export surge that will run headlong into Western efforts to promote green technologies? Scariest of all, will it try to distract from domestic difficulties by engaging in military adventurism?

“The evolution of cooperation required out-group hatred. Which is really sad,” said Nicholas Christakis, a Yale sociologist and author of “Blueprint: The Evolutionary Origins of a Good Society.”

No researcher argues that human nature is the sole, or even the primary, cause of today’s polarization. But savvy political operatives can exploit, leverage and encourage it. And those operatives are learning from their triumphs in divide-and-conquer politics.

“We wouldn’t have civilizations if we didn’t create groups. We are designed to form groups, and the only way to define a group is there has to be someone who’s not in it,” Mason said.

Experiments have revealed that “children as young as two will prefer other children randomly assigned to the same T-shirt color,”

enmity and derision can arise independently of any rational reason for it.

Mason and Christakis point to a famous-among-academics experiment from 1954. Social psychologist Muzafer Sherif took 22 Boy Scouts and separated them into two groups camping at Robbers Cave State Park in Oklahoma. Only after a week did they learn that there was another group at the far end of the campground.

What they did next fascinated the research team. Each group developed irrational contempt for the other. The boys in the other group were seen not just as rivals, but as fundamentally flawed human beings. Only when the two groups were asked to work together to solve a common problem did they warm up to one another.

And because many more districts are now deeply red or blue, rather than a mix of constituencies, House members have fewer reasons to adopt moderate positions.

“Homo sapiens is a social species; group affiliation is essential to our sense of self. Individuals instinctively think of themselves as representing broad socioeconomic and cultural categories rather than as distinctive packages of traits,”

Here’s where psychology gives way to political science. The American political system may cultivate “out-group” hatred, as academics put it. One of the scarce resources in this country is political power at the highest levels of government. The country has no parliamentary system in which multiple parties form governing coalitions.

Add to this fact the redistricting that ensures there are fewer truly competitive congressional races. The two parties have inexorably moved further apart ideologically, and leaders are more likely to be punished — “primaried” — if they reach across the aisle.

Shanto Iyengar, a Stanford political psychologist who coined the term “affective polarization,” explained in a 2018 paper why people typically identify with a group.

Human nature hasn’t changed, but technology has. The fragmentation of the media has made it easier to gather information in an echo chamber, Iyengar said. He calls this “sorting.” Not only do people cluster around specific beliefs or ideas, they physically cluster, moving to neighborhoods where residents are likely to look like them and think like them.

Partisan clustering has increased even within households. In 1965, Iyengar said, only about 60 percent of married couples had the same party registration. Today, the figure is greater than 85 percent

Asked in the summer of 2022 if they agree or disagree that members of the other party “lack the traits to be considered fully human — they behave like animals,” about 30 percent in both parties agreed, Mason’s research shows.

Research shows that affective polarization is intensifying across the political spectrum. Recent survey data revealed that more than half of Republicans and Democrats view the other party as “a threat,” and nearly as many agree with the description of the other party as “evil,” Mason said.

A recent paper published in the journal Science argued that the three core ingredients of political sectarianism are “othering, aversion, and moralization.” Trump has mastered that recipe. He activates emotional responses in his followers by telling them that they are threatened.

As for our continuing distress, the standard explanation is a uniquely American loneliness. The surgeon general, Vivek Murthy, declared it an epidemic in its own right.

The truth, however, is there’s no good evidence that Americans are lonelier than ever

a major recent poll shows that older Americans are now significantly less lonely than they were three years ago; a recent peer-reviewed study reports that middle-aged Americans describe themselves as less lonely than they were 20 years ag

Loneliness is more pervasive among younger Americans, but there too, the rates have also plummeted since 2020

Logically, we should be feeling better. Why can’t we shake this thing?

loneliness was never the core problem. It was, rather, the sense among so many different people that they’d been left to navigate the crisis on their own. How do you balance all the competing demands of health, money, sanity?

The answer was always the same: Figure it out.

while other countries built trust and solidarity, America — both during and after 2020 — left millions to fend for themselves.

For millions of Americans, distrust feels like the most rational state.

The very different people I spoke with that year all had one thing in common: a feeling that in the wake of Covid, all the larger institutions they had been taught to trust had failed them. At the most precarious times in their lives, they found there was no system in place to help.

four years later, the situation is, if anything, worse.

Nursing homes across the country, where poor labor conditions were linked to higher Covid mortality levels, remain understaffed, leaving old, frail residents more vulnerable than they should be. Hunger and food insecurity remain wrenching emergencies.

Students haven’t fully returned to school. Congress passed the Child Poverty Reduction Act of 2021, one of the most effective antipoverty measures in decades. Then a year later, Congress ended it, pushing some five million young people back down into extreme financial need.

When everything was uncertain and everyone’s future was on the line, we walked right up to the precipice of a moral breakthrough, and then we turned back.

Look at the way we all accustomed ourselves to the term “essential worker,” an ostensible term of respect that instead condemned people to work in manifestly dangerous conditions. The adoption of that term made visible something we now cannot unsee: In the United States the people we rely on most to keep our world functioning are the people we treated as disposable.

we might call the bigger problem structural isolation: abandoned by employers, deprived of shared purpose, denied care. The combined effect sent a strong message that individual lives weren’t worth as much anymore.

People treated one another accordingly. We all remember the viral videos of people screaming at one another in supermarkets and on public transportation. Violent crime spiked. Even reckless driving surged — but it happened only in the United States.

The reasons for that American exceptionalism become only more urgent in an election year, when, as in a public health crisis, presidents can try to bring people together or try to turn them against one another.

The result is that less energy is being produced overall, and Germany is loath to buy it from France—where power is much cleaner, because it’s mostly nuclear.

So who absorbed the adjustment? Easy: industry, the old backbone of the German manufacturing state, which has been closing production facilities in significant numbers.

This does not, of course, reduce the overall atmospheric pollution generated in the world, as the old clients of German firms turn to alternatives in other locations that are, almost always, fueled with high carbon sources. The Indonesian, Brazilian, Indian and Chinese companies that will now manufacture the products that German workers used to make are largely run on fossil fuels.

Part of the problem is that there are inherent technical limitations to how high a country can drive wind and solar in its energy mix. State of the art lithium-ion batteries can only store energy in the range of megawatts, up to the low gigawatts. In order to store electricity to survive a German winter with next to no sunlight and long low-wind periods, the country would need to increase its storage capacity by orders of magnitude.

There are only three presently known energy sources that can be used at scale to balance a natural grid: hydroelectricity, nuclear and fossil fuels

hey decided to simply make do with less power: economic degrowth in action. Of course, people depended on those power sources for jobs: good, well-paid, stable union jobs that guys without university degrees could get. The government closed down the factories—can they really be surprised some of these people now want to vote for the far right?

Germany didn’t adopt degrowth by choice, but through a series of blunders. The comic edge of its misfortunes is that so many of them occurred because of miscalculation or just sheer bloody-mindedness on the part of the Greens and Social Democrats. First, a few months before becoming a Russian energy lobbyist in 2005, then-Chancellor Gerhard Schröder insisted on putting Russian natural gas at the core of Germany’s energy grid, continuing a Social Democratic tradition of entwining Germany’s future with Russia’s. Then, a Green Party with its roots in 1970s anti-nuclear weapons activism carried this atavistic policy into the 21st century when it entered government, insisting that Germany decommission the backbone of its zero-emission energy matrix. Then the war in Ukraine happened, and the pipelines were cut. Oooops. Guess who’s digging for coal now?

Among the right, a new kind of reactionary self-help is ascendant. Its mainstream version is legible in the manosphere misogyny of Jordan Peterson, Joe Rogan, and Andrew Tate, while more eldritch currents lurk just beneath the surface. The Nietzscheanism of internet personalities like Bronze Age Pervert—who combines ethnonationalist chauvinism in politics and personal life with a Greco-Roman obsession with physical fitness—is only one of many examples of the trend the social critic Maya Vinokour has called “lifestyle fascism.”

We might call this turbocharged version of authenticity culture “therapeutic libertarianism”: the belief that self-improvement is the ultimate goal of life, and that no formal or informal constraints—whether imposed by states, faith systems, or other people—should impede each of us from achieving personal growth

This attitude is therapeutic because it is invariably couched in self-help babble. And it is libertarian not only because it makes a cult out of personal freedom, but because it applies market logic to human beings. We are all our own start-ups. We must all adopt a pro-growth mindset for our personhood and deregulate our desires.

We must all assess and reassess our own “fulfillment,” a kind of psychological Gross Domestic Product, on a near-constant basis. And like the GDP, our fulfillment must always increase.

On the left, what gets termed “wokeness” is indissociable from self-help. How should we understand superficial, performative expressions of “anti-racism” or preening social-media politics if not as a way for self-described good-hearted liberals to make grand public displays of pruning their moral shrubbery?

Stewart’s response to the UTIs is not concern for his wife but irritation: “This guy is breaking all my toys,” he grumbles. When she gets upset that her husband keeps calling her a “cunt” and a “whore” during sex—something he professes not being able to help—Stewart does not change this habit. Instead they strike a preposterous bargain: “He will try his best not to scream cunt during sex, and I will do my best to ignore him if he does.”

What the author is trying to find in her open relationship is not sex, but self-understanding—what it means, how we get it, whether sex can provide it. And although the answers Molly arrives at are not cheaply won, they are cheap all the same.

Near the end of the memoir, the author’s mother provides the empty epiphany toward which the text careens. “Everything that happens in life,” her mom offers, “is an opportunity to learn about yourself. Marriage. Motherhood. Relationships. Even anger and illness. Nothing that happens is good or bad in and of itself. It’s all just an opportunity to learn and grow.” With this maternal revelation, Molly’s “skin starts to tingle.” She relates that the advice “feels almost holy.”

though Molly may tell herself and her readers that she is on a journey of learning and growth, the ugly truth is that More feels like a 290-page cry for help. Molly does not come off as a woman boldly finding herself, but rather as someone who is vulnerable to psychological manipulation and does not enjoy her open marriage.

if it seems like Molly Roden Winter does not want to be in an open marriage, it is because she often lets us know that she doesn’t want to be in an open marriage.

When a couples therapist asks the pair why they’re in counseling halfway through the book—prompted by a breakdown Molly experiences that stems from their marital arrangement—she explains: “We’re here because I don’t want to be in an open marriage anymore, but Stewart does.”

There are precious few sex scenes where Molly seems to be enjoying herself. When Molly is in the middle of a squirmy threesome she’s been dreading, she literally dissociates from her body, pretending that she is a director staging a scene in which her physical person is merely an actor. Molly describes how she performs her role with “a clinician’s detachment” and leaves the apartment rapidly so as not “to be pulled back into this scene.” After one of her dates repeatedly removes his condom without her consent—an act known as “stealthing,” which is considered a sex crime in a number of countries and the state of California—she contracts a series of urinary tract infections

his concept doesn’t quite capture the extent to which this relentless quest for self-optimizing authenticity has infused our social and even political sensibilities.

Winter is trapped in her therapeutic worldview, one imposed on her by an American culture that has made narcissism into not simply a virtue, but a quasi-religion that turns external obstacles into opportunities for internal self-improvement.

These obstacles include, in her case, profound gender inequality relating to Molly’s life as a parent to two sons, and a troubling family history. Molly’s mother joined a cult—and indoctrinated the author into it as a child—at the urging of a male partner in her own open marriage. The book makes tacit comparisons between Molly’s mother’s initiation into a cult at the behest of an extramarital partner, and Molly’s own initiation into an open marriage at the behest of her husband.

throughout More, the dominant emotion Molly reports is not lust but rage—primarily at the deeply unequal child-care burdens that are placed upon her. “I think about all the years I’ve spent my night alone with the kids—the dinners, the bedtimes, the dishes, the loneliness of doing it all by myself—because Stew had to work,” she laments at one point. That Stewart is now spending late nights not working (if he ever was) but rather schtupping his endless reserve of mistresses pushes Molly further to the brink: “I feel my jealousy mingle with the resentment I’ve kept at bay for years,”

Molly doubles down on her quest for self-actualization through the relentless pursuit of bitter novelty: new sexual experiences that she rarely seems to enjoy, new partners who rarely treat her kindly.

The only solution Molly can imagine is to persist in an open marriage, rather than push for an equal one. Inward sexual revolution plainly feels more possible than a revolution in who does the dishes.

Research published in the weekly Der Spiegel shows that the AfD, a party started by nationally minded economists who advocated a return to the Deutsche mark as the national currency, now uses language nearly identical to that of the defunct National Democratic Party of Germany (NPD), a small, virulently xenophobic, and openly neo-Nazi party that ran in German elections for decades but never managed to win seats in the Bundestag.

“They have major ideological overlaps. The AfD measures up to the NPD [of 2012] in almost all areas, even if the AfD appears more moderate in its party program.”

Documents attributed to both parties employ reactionary terminology, some of it straight from Nazi Germany, such as Umvolkung (population replacement) and Volkstod (death of the German nation), as well as Stimmvieh (voting cattle) for voters of opposing parties and Passdeutschen (foreign nationals holding German passports). And like the NPD, Spiegel reported in another study, the AfD maintains close links with violent militants.

this radicalism, which in the past had turned Germans off, has now lifted the AfD to new heights: It is polling at 22 percent support nationwide, second only to the Christian Democrats, and well over 30 percent in several states, making it the number one political force there in advance of autumn elections.

The current outburst of popular indignation at the AfD, echoed by all of the other major political parties, comes on the heels of an investigative exposé that found that at a clandestine meeting in November, ranking AfD personalities met with known neo-Nazis and wealthy financiers to hammer out plans for the forced deportation of foreign nationals and even foreign-born German citizens.

The extremists congregated at a hotel near Potsdam to design what they called a “remigration master plan” to forcibly repatriate millions of people. Shocked observers drew parallels to the 1942 Wannsee Conference, held not far from Potsdam, at which the Nazis coordinated their plan to deport and murder the entire Jewish population of Europe.

While some AfD politicos have tried to distance the party from the Potsdam meeting, others endorsed its purpose. “Remigration is not a secret plan, but a promise. … and there’s no better way to put it,” announced Hans-Christoph Berndt, the AfD point person in the Brandenburg state parliament, on Jan. 17.

they confirm the diagnosis of many experts that the AfD, under the leadership of its most extreme figures—particularly Björn Höcke, a member of the Thuringia legislature—has outpaced other European far-right parties in its radicalism. “The current AfD wouldn’t find a place in the ranks of the Sweden Democrats and most of the other more moderate far-right parties among the European Conservatives and Reformists faction in the European Parliament,”

She explained that like the AfD, the Sweden Democrats, the Finns Party (formerly the True Finns), and the Danish People’s Party are opposed to immigration and favor law-and-order states. But the Nordic rightists’ experiences in office pushed them to adapt to mainstream norms and policy options. (The Sweden Democrats are currently an informal supporter of the Swedish ruling coalition; the Finns are a coalition member in Finland; and the DPP acted as a support party to a conservative Danish government between 2001 and 2011, as well as from 2015 to 2019.)

The radicalized AfD, Jungar said, in contrast to these parties, actively courts militants, trades in antisemitic tropes, and toys with the proposition of Germany exiting NATO and the European Union

Moreover, AfD politicians have stood against adoption rights for same-sex couples, the inclusion of disabled kids in schools, and the legality of abortion. “These positions simply wouldn’t stand a chance in Sweden,”

“The FPO under Kickl has moved further to the right. It is now indistinguishable from the right-wingers in the AfD,” he argued. “They want people who they think don’t belong here out of Austria. They don’t want to gas them yet, but they want to strip people of their citizenship. They want to cut people’s social benefits to such an extent that their livelihoods are destroyed. That is essentially the program of parties like the AfD and the FPO. They harbor fantasies ranging from populist to fascist.

“By stacking the courts and clamping down on opposition forces, these parties gradually undermined the democratic order,” Opratko said. “This is the AfD’s model. It’s what they want to do.”

The simplest way of outlining the ideal university policy toward protest is to say that it should protect free speech, respect civil disobedience and uphold the rule of law

universities should protect the rights of students and faculty on a viewpoint-neutral basis, and they should endeavor to make sure that every member of the campus community has the same access to campus facilities and resources.

That also means showing no favoritism between competing ideological groups in access to classrooms, in the imposition of campus penalties and in access to educational opportunities

Indefinitely occupying a quad violates the rights of other speakers to use the same space. Relentless, loud protest violates the rights of students to sleep or study in peace. And when protests become truly threatening or intimidating, they can violate the civil rights of other students, especially if those students are targeted on the basis of their race, sex, color or national origin.

Noise limits can protect the ability of students to study and sleep. Restricting the amount of time any one group can demonstrate on the limited open spaces on campus permits other groups to use the same space.

Civil disobedience is distinct from First Amendment protected speech. It involves both breaking an unjust law and accepting the consequences.

In a 1965 appearance on “Meet the Press,” the Rev. Dr. Martin Luther King Jr. described the principle perfectly: “When one breaks the law that conscience tells him is unjust, he must do it openly, he must do it cheerfully, he must do it lovingly, he must do it civilly — not uncivilly — and he must do it with a willingness to accept the penalty.”

But what we’re seeing on a number of campuses isn’t free expression, nor is it civil disobedience. It’s outright lawlessness

reasonable time, place and manner restrictions are indispensable in this context. Time, place and manner restrictions are content-neutral legal rules that enable a diverse community to share the same space and enjoy equal rights.

Administrators and faculty members will often abandon any pretense of institutional neutralit

For many administrators, the very idea of neutrality is repugnant. It represents a form of complicity in injustice that they simply can’t and won’t stomach. So they nurture and support one side. They scorn the opposition, adopting a de facto posture that says, “To my friends, everything; for my enemies, the law.”

In March, a small band of pro-Palestinian students at Vanderbilt University in Nashville pushed past a security guard so aggressively that they injured him, walked into a university facility that was closed to protest, and briefly occupied the building. The university had provided ample space for protest, and both pro-Israel and pro-Palestinian students had been speaking and protesting peacefully on campus since Oct. 7.

But these students weren’t engaged in free speech. Nor were they engaged in true civil disobedience. Civil disobedience does not include assault, and within hours the university shut them down. Three students were arrested in the assault on the security guard, and one was arrested on charges of vandalism. More than 20 students were subjected to university discipline; three were expelled; and one was suspended.

The University of Chicago has long adhered to the Kalven principles, a statement of university neutrality articulated in 1967 by a committee led by one of the most respected legal scholars of the last century, Harry Kalven Jr. At their heart, the Kalven principles articulate the view that “the instrument of dissent and criticism is the individual faculty member or the individual student. The university is the home and sponsor of critics; it is not itself the critic. It is, to go back once again to the classic phrase, a community of scholars.”

In other words, the cultural crackup of the last few months only appears to be part of an international conflict. It is, in fact, resolutely German. What is really being fought over here is a hazy, transcendent national concept that, since Oct. 7, has overtaken more firmly constitutional principles of free expression and free association.

The tensions have been building since at least 2019, when the federal Parliament adopted a resolution designating the movement calling for a boycott of Israel as antisemitic, and urging local governments and “public stakeholders” not to fund organizations or individuals that support it. That makes a big difference here, since so many artists, writers and musicians receive generous government aid. The resolution, though nonbinding, led some cultural institutions to rescind invitations to critics of Israeli policy, and many more to take a hesitant approach.

“People in cultural institutions are risk-averse,” said Tobias Haberkorn, who edits the Berlin Review, a new literary publication. “So if they have to decide, ‘Am I going to invite this or that artist with a Middle Eastern background, or not?’ I can very well see them not inviting them. Just to avoid the potential hassle.”

Since Oct. 7, accusations of antisemitism have flown much more broadly. Some are merited. Many others are dubious. Quite a number of those accused of antisemitism have been Jewish, such as Gessen.

“There are many Jewish perspectives, and that is not being honored here in a country where the history cannot be excused,” said Peaches, who is also Jewish. “For any progressive Jewish person who is thinking about what is going on, and understanding the history of what is going on, to be called antisemitic — by Germans — is ridiculous. Never did I think in 2024 that I would be thinking about that.”

Yet it’s worth pointing out how few of these accusations revolve around cultural production. It is rare for Berlin’s theaters or festivals to cancel someone for what they actually sing or paint or film

What gets you now are statements, posts, likes, signatures: the imperatives of social media, which are swallowing culture wholesale. Once debates like this would have played out in Germany’s elite press, where intellectuals clashed over the country’s moral responsibility to the past. Today the national papers, and the institutions too, are playing catch-up to Ruhrbarone, a small website from the provincial city of Bochum that took down Anderson and many others.

Republican politicians, sensing momentum, called on other firms to follow suit.

“This was always cosmetic,” said Shivaram Rajgopal, a professor at Columbia Business School. “If signing a piece of paper was getting these companies into trouble, it’s no surprise they’re getting the hell out.

American asset managers have a fiduciary duty to act in the best interest of their clients, and the financial firms were worried that a new strategy by Climate Action 100+ could expose them to legal risks.

Since its founding in 2017, the group focused on getting publicly traded companies to increase how much information they shared about their emissions and identify climate-related risks to their businesses.

In addition to the risk that some clients might disapprove, and potentially sue, there were other concerns. Among them: that acting in concert to shape the behaviors of other companies could fall afoul of antitrust regulations.

The new plan called on asset-management firms to begin pressuring companies like Exxon Mobil and Walmart to adopt policies that could entail, for example, using fewer fossil fuels

last year, Climate Action 100+ said it would shift its focus toward getting companies to reduce emissions with what it called phase two of its strategy

BlackRock also said that one of its subsidiaries, BlackRock International, would continue to participate in the group — a tacit acknowledgment of the different regulatory environment in Europe. BlackRock also said it was initiating new features that would let clients choose if they wanted to pressure companies to reduce their emissions.

Pimco, another big asset manager, followed suit. “We have concluded that our Climate Action 100+ participation is no longer aligned with PIMCO’s approach to sustainability,” a firm spokesman said in a statement.

JPMorgan said it was pulling out of the group in recognition of the fact that, over the past few years, the firm had developed its own framework for engaging on climate risk

The fracturing of Climate Action 100+ was a victory for Representative Jim Jordan, Republican of Ohio, who has led a campaign against companies pursuing E.S.G. goals, shorthand for environmental, social and governance factors.

Embracing E.S.G. principles and speaking up on climate issues has become commonplace across corporate America in recent years. Chief executives warned about the dangers of climate change. Banks and asset managers formed alliances to phase out fossil fuels. Trillions of dollars were allocated for sustainable investing.

“Phase two is not that different,” she said. “It’s basically investors working with companies and saying: ‘OK, you’ve disclosed the risk. We just want to know how you’re going to address it.’ Because that’s what the investors want. How are you dealing with risk?”

Mindy Lubber, the chief executive of Ceres and a member of the steering committee of Climate Action 100+, disputed the notion that the new strategy represented a change from the focus on enhanced disclosure.

“The political cost has heightened, the legal risk has heightened,” he said. “That said, these corporations are not doing U-turns,” he added. “They continue to consider climate. That’s not going away. It’s adapting to the current environment.”

Aron Cramer, chief executive for BSR, a sustainable-business consultancy, said the Wall Street firms were responding to political pressure, but not abandoning their climate commitments altogether.

Several of the firms that backed out of Climate Action 100+ said they remained committed to the issue. JPMorgan said that it had a team of 40 people working on sustainable investing and that it believed “climate change continues to present material economic risks and opportunities to our clients.”

it is clear that its widespread adoption is a matter of when, not if. There is no debate that we are moving towards a world where “real life” and digital technology seamlessly blur

Researchers from Stanford and Michigan University recently undertook a study on the Vision Pro and other “passthrough” headsets (that’s the technical term for the feature which brings VR content into your real-world surrounding so you see what’s around you while using the device) and emerged with some stark warnings about how this tech might rewire our brains and “interfere with social connection”.

more broadly, spatial computing is going to alter what we consider reality

Over the years there have been multiple reports of people being harassed and even “raped” in the metaverse: an experience that feels scarily real because of how immersive virtual reality is. As the lines between real life and the digital world blur to a point that they are almost indistinguishable, will there be a meaningful difference between online assault and an attack in real life?

These headsets essentially give us all our private worlds and rewrite the idea of a shared reality. The cameras through which you see the world can edit your environment – you can walk to the shops wearing it, for example, and it might delete all the homeless people from your view and make the sky brighter.

“What we’re about to experience is, using these headsets in public, common ground disappears,”

“People will be in the same physical place, experiencing simultaneous, visually different versions of the world. We’re going to lose common ground.”

It’s not just the fact that our perception of reality might be altered that’s scary: it’s the fact that a small number of companies will have so much control over how we see the world. Think about how much influence big tech already has when it comes to content we see, and then multiply that a million times over. You think deepfakes are scary? Wait until they seem even more realistic.

We’re seeing a global rise of authoritarianism. If we’re not careful this sort of technology is going to massively accelerate it.

Being able to suck people into an alternate universe, numb them with entertainment, and dictate how they see reality? That’s an authoritarian’s dream. We’re entering an age where people can be mollified and manipulated like never before

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.”

At some point they will be able to, for example, suggest recipes for novel cyberattacks or biological attacks—all based on publicly available knowledge.

But as models become more sophisticated, this approach may prove insufficient. Some models are beginning to exhibit polymathic behavior: They appear to know more than just what is in their training data and can link concepts across fields, languages, and geographies.

We need to adopt new approaches to AI safety that track the complexity and innovation speed of the core models themselves.

What’s much harder to test for is what’s known as “capability overhang”—meaning not just the model’s current knowledge, but the derived knowledge it could potentially generate on its own.

Red teams have so far shown some promise in predicting models’ capabilities, but upcoming technologies could break our current approach to safety in AI. For one, “recursive self-improvement” is a feature that allows AI systems to collect data and get feedback on their own and incorporate it to update their own parameters, thus enabling the models to train themselves

This could result in, say, an AI that can build complex system applications (e.g., a simple search engine or a new game) from scratch. But, the full scope of the potential new capabilities that could be enabled by recursive self-improvement is not known.

Another example would be “multi-agent systems,” where multiple independent AI systems are able to coordinate with each other to build something new.

This so-called “combinatorial innovation,” where systems are merged to build something new, will be a threat simply because the number of combinations will quickly exceed the capacity of human oversight.

Short of pulling the plug on the computers doing this work, it will likely be very difficult to monitor such technologies once these breakthroughs occur

Current regulatory approaches are based on individual model size and training effort, and are based on passing increasingly rigorous tests, but these techniques will break down as the systems become orders of magnitude more powerful and potentially elusive

AI regulatory approaches will need to evolve to identify and govern the new emergent capabilities and the scaling of those capabilities.

But the AI Act has already fallen behind the frontier of innovation, as open-source AI models—which are largely exempt from the legislation—expand in scope and number

Europe has so far attempted the most ambitious regulatory regime with its AI Act,

both Biden’s order and Europe’s AI Act lack intrinsic mechanisms to rapidly adapt to an AI landscape that will continue to change quickly and often.

a gathering in Palo Alto organized by the Rand Corp. and the Carnegie Endowment for International Peace, where key technical leaders in AI converged on an idea: The best way to solve these problems is to create a new set of testing companies that will be incentivized to out-innovate each other—in short, a robust economy of testing

To check the most powerful AI systems, their testers will also themselves have to be powerful AI systems, precisely trained and refined to excel at the single task of identifying safety concerns and problem areas in the world’s most advanced models.

To be trustworthy and yet agile, these testing companies should be checked and certified by government regulators but developed and funded in the private market, with possible support by philanthropy organizations

The field is moving too quickly and the stakes are too high for exclusive reliance on typical government processes and timeframes.

One way this can unfold is for government regulators to require AI models exceeding a certain level of capability to be evaluated by government-certified private testing companies (from startups to university labs to nonprofit research organizations), with model builders paying for this testing and certification so as to meet safety requirements.

As AI models proliferate, growing demand for testing would create a big enough market. Testing companies could specialize in certifying submitted models across different safety regimes, such as the ability to self-proliferate, create new bio or cyber weapons, or manipulate or deceive their human creators

Much ink has been spilled over presumed threats of AI. Advanced AI systems could end up misaligned with human values and interests, able to cause chaos and catastrophe either deliberately or (often) despite efforts to make them safe. And as they advance, the threats we face today will only expand as new systems learn to self-improve, collaborate and potentially resist human oversight.

If we can bring about an ecosystem of nimble, sophisticated, independent testing companies who continuously develop and improve their skill evaluating AI testing, we can help bring about a future in which society benefits from the incredible power of AI tools while maintaining meaningful safeguards against destructive outcomes.

It turns out that if you give everyone access to the Library of Congress, what they do is watch videos on TikTok

A chatbot is not an oracle; it’s a statistics engine that creates sentences that sound accurate. Right now my sense is that it’s like we’ve just invented transistors. We’ve got a couple of consumer products that people are starting to adopt, like the transistor radio, but we don’t yet know how the transistor will transform society

We’re in the transistor-radio stage of AI. I think a lot of the ferment that’s happening right now in the industry is venture capitalists putting money into business plans, and teams that are rapidly evaluating a whole lot of different things that could be done well. I’m sure that some things are going to emerge that I wouldn’t dare try to predict, because the results of the creative frenzy of millions of people is always more interesting than what a single person can think of.

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

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.

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.

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.

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.
