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.

This finding is the latest example of how tough it is to vet products we buy online. Buggy software in off-brand smart devices is a recurring problem

digital marketplaces such as Amazon have done little to rein in offending manufacturers. Combine that with sponsored search results and opaque labeling — Amazon repeatedly called the Eken doorbells an “Amazon’s Choice: Overall Pick” — and shoppers have little recourse to figure out which devices are safe.

Smaller brands churn out smart lightbulbs and speakers to compete with bigger companies, often cutting corners on security. Big brands, meanwhile, do a better job with security but create new privacy concerns — do we really want Amazon peeking into every corner of our homes? Efforts to label consumer tech with simple security facts have languished.

Meanwhile, large online marketplaces put unvetted gadgets in front of millions of shoppers. In January alone, Amazon sold 4,200 Eken doorbells under 11 product listings, according to Consumer Reports. Whether you’re shopping for smart home tech or a simple tank top, having to navigate a sea of unfamiliar brands and dubious product reviews is now common

a major extinction panic happened 100 years ago, and the similarities are unnerving.

The 1920s were also a period when the public — traumatized by a recent pandemic, a devastating world war and startling technological developments — was gripped by the conviction that humanity might soon shuffle off this mortal coil.

It also helps us see how apocalyptic fears feed off the idea that people are inherently violent, self-interested and hierarchical and that survival is a zero-sum war over resources.

Either way, it’s a cynical view that encourages us to take our demise as a foregone conclusion.

What makes an extinction panic a panic is the conviction that humanity is flawed and beyond redemption, destined to die at its own hand, the tragic hero of a terrestrial pageant for whom only one final act is possible

What the history of prior extinction panics has to teach us is that this pessimism is both politically questionable and questionably productive. Our survival will depend on our ability to recognize and reject the nihilistic appraisals of humanity that inflect our fears for the future, both left and right.

As a scholar who researches the history of Western fears about human extinction, I’m often asked how I avoid sinking into despair. My answer is always that learning about the history of extinction panics is actually liberating, even a cause for optimism

Nearly every generation has thought its generation was to be the last, and yet the human species has persisted

As a character in Jeanette Winterson’s novel “The Stone Gods” says, “History is not a suicide note — it is a record of our survival.”

Contrary to the folk wisdom that insists the years immediately after World War I were a period of good times and exuberance, dark clouds often hung over the 1920s. The dread of impending disaster — from another world war, the supposed corruption of racial purity and the prospect of automated labor — saturated the period

The previous year saw the publication of the first of several installments of what many would come to consider his finest literary achievement, “The World Crisis,” a grim retrospective of World War I that laid out, as Churchill put it, the “milestones to Armageddon.

Bluntly titled “Shall We All Commit Suicide?,” the essay offered a dismal appraisal of humanity’s prospects. “Certain somber facts emerge solid, inexorable, like the shapes of mountains from drifting mist,” Churchill wrote. “Mankind has never been in this position before. Without having improved appreciably in virtue or enjoying wiser guidance, it has got into its hands for the first time the tools by which it can unfailingly accomplish its own extermination.”

The essay — with its declaration that “the story of the human race is war” and its dismay at “the march of science unfolding ever more appalling possibilities” — is filled with right-wing pathos and holds out little hope that mankind might possess the wisdom to outrun the reaper. This fatalistic assessment was shared by many, including those well to Churchill’s left.

“Are not we and they and all the race still just as much adrift in the current of circumstances as we were before 1914?” he wondered. Wells predicted that our inability to learn from the mistakes of the Great War would “carry our race on surely and inexorably to fresh wars, to shortages, hunger, miseries and social debacles, at last either to complete extinction or to a degradation beyond our present understanding.” Humanity, the don of sci-fi correctly surmised, was rushing headlong into a “scientific war” that would “make the biggest bombs of 1918 seem like little crackers.”

The pathbreaking biologist J.B.S. Haldane, another socialist, concurred with Wells’s view of warfare’s ultimate destination. In 1925, two decades before the Trinity test birthed an atomic sun over the New Mexico desert, Haldane, who experienced bombing firsthand during World War I, mused, “If we could utilize the forces which we now know to exist inside the atom, we should have such capacities for destruction that I do not know of any agency other than divine intervention which would save humanity from complete and peremptory annihilation.”

F.C.S. Schiller, a British philosopher and eugenicist, summarized the general intellectual atmosphere of the 1920s aptly: “Our best prophets are growing very anxious about our future. They are afraid we are getting to know too much and are likely to use our knowledge to commit suicide.”

Many of the same fears that keep A.I. engineers up at night — calibrating thinking machines to human values, concern that our growing reliance on technology might sap human ingenuity and even trepidation about a robot takeover — made their debut in the early 20th century.

The popular detective novelist R. Austin Freeman’s 1921 political treatise, “Social Decay and Regeneration,” warned that our reliance on new technologies was driving our species toward degradation and even annihilation

Extinction panics are, in both the literal and the vernacular senses, reactionary, animated by the elite’s anxiety about maintaining its privilege in the midst of societal change

There is a perverse comfort to dystopian thinking. The conviction that catastrophe is baked in relieves us of the moral obligation to act. But as the extinction panic of the 1920s shows us, action is possible, and these panics can recede

To whatever extent, then, that the diagnosis proved prophetic, it’s worth asking if it might have been at least partly self-fulfilling.

today’s problems are fundamentally new. So, too, must be our solutions

It is a tired observation that those who don’t know history are destined to repeat it. We live in a peculiar moment in which this wisdom is precisely inverted. Making it to the next century may well depend on learning from and repeating the tightrope walk — between technological progress and self-annihilation — that we have been doing for the past 100 years

We have gotten into the dangerous habit of outsourcing big issues — space exploration, clean energy, A.I. and the like — to private businesses and billionaires

That ideologically varied constellation of prominent figures shared a basic diagnosis of humanity and its prospects: that our species is fundamentally vicious and selfish and our destiny therefore bends inexorably toward self-destruction.

Less than a year after Churchill’s warning about the future of modern combat — “As for poison gas and chemical warfare,” he wrote, “only the first chapter has been written of a terrible book” — the 1925 Geneva Protocol was signed, an international agreement banning the use of chemical or biological weapons in combat. Despite the many horrors of World War II, chemical weapons were not deployed on European battlefields.

As for machine-age angst, there’s a lesson to learn there, too: Our panics are often puffed up, our predictions simply wrong

In 1928, H.G. Wells published a book titled “The Way the World Is Going,” with the modest subtitle “Guesses and Forecasts of the Years Ahead.” In the opening pages, he offered a summary of his age that could just as easily have been written about our turbulent 2020s. “Human life,” he wrote, “is different from what it has ever been before, and it is rapidly becoming more different.” He continued, “Perhaps never in the whole history of life before the present time, has there been a living species subjected to so fiercely urgent, many-sided and comprehensive a process of change as ours today. None at least that has survived. Transformation or extinction have been nature’s invariable alternatives. Ours is a species in an intense phase of transition.”

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

the red-blue divide is perhaps less illuminating than the gap between engaged and disengaged Americans, in which an exhausted majority encounters the highly polarized activist wings of both parties and shrinks back from the fray

The wings aren’t changing each other’s minds — hard-core Democrats aren’t going to persuade hard-core Republicans — but they’re also not reaching sufficient numbers of persuadable voters to break America’s partisan deadlock.

In 2020, when I was doing research for my book about the growing danger of partisan division, I began to learn more about what extreme partisanship does not only to our hearts but also to our minds.

It can deeply and profoundly distort the way we view the world. We become so emotionally and spiritually invested in the outcome of a political contest that we can inadvertently become disconnected from reality.

Our heart connects with our mind in such a way that the heart demands that the mind conform to its deepest desires

When a partisan encounters negative information, it can often trigger the emotional equivalent of a fight-or-flight response. This applies not just to negative arguments but also to negative facts. To deal with the emotional response, we seek different arguments and alternative facts.

If you are a true partisan, you essentially become an unpaid lawyer for your side. Every “good” fact that bolsters your argument is magnified. Every “bad” fact is minimized or rationalized.

When partisanship reaches its worst point, every positive claim about your side is automatically believed, and every negative allegation is automatically disbelieved.

allegations of wrongdoing directed at your side are treated as acts of aggression — proof that “they” are trying to destroy “us.”

You see this reality most plainly in the daily Republican theatrics surrounding Trump’s criminal indictments. Rather than wrestle seriously with the profoundly troubling claims against him, they treat the criminal cases as proof of Democratic perfidy. They believe every claim against Hunter and Joe Biden and not a single claim against Trump.

ask why people are checking out, and one reason is that partisans make it so very difficult to engage.

The problem is most pronounced (and often overtly threatening) on the MAGA right, but it’s endemic to our partisan wings

as partisanship deepens, partisan subcultures can get increasingly weird. They become so convinced of the us-versus-them dynamic that they’ll eventually believe virtually anything, as long as it’s a claim against the other side.

If decades of partisanship have persuaded you that your opponents are evil, have no morals and want to destroy the country, then why wouldn’t they hack voting machines or recruit a pop star as a government asset?

I have some rules to help temper my worst partisan impulses.

Expose yourself to the best of the other side’s point of view — including the best essays, podcasts and books.

when you encounter a new idea, learn about it from its proponents before you read its opponents.

when you encounter bad news about a cause that you hold dear — whether it’s a presidential campaign, an international conflict or even a claim against a person you admire, take a close and careful look at the evidence

Everywhere, new investment in green energy generation is being propelled by general concern for the climate, shifting corporate and household demand, the plunging prices for solar and batteries triggered by Chinese policy, and a combination of national and regional interventions

How different would we expect this data to look without the IRA?

The most useful overview of these modeling efforts that I have been able to find is by Bistline et al “Power sector impacts of the Inflation Reduction Act of 2022” in Environmental Research Letters November 2023. If anyone has a better source, please let me know.

The top panel shows the historical trajectory of US generating capacity from 1980 to 2021. The second half of the graphic shows how 11 different models predict that the US electricity system might be expected to develop up to 2035, with and without IRA.

all the models expect the trends of the 2010s to continue through to the 2030s which means that solar, wind and battery storage dominate America’s energy future. Even without the IRA, the low carbon share of electricity generation will likely rise to 50-55% by 2035. Bidenomics bumps that to 70-80 percent.

The question is: “How does the renewable surge of 2022-2024, compare to the model-based expectations, with and without the IRA?”

The answer is either, “so so”, or, more charitably, it is “too early to tell”. In broad terms the current rate of expansion is slightly above the rate the models predict without the provision of additional Bidenomics incentives. But what is also clear is that the current rate of expansion, is far short of the long-run pace that should be expected from the IRA

At this point, defenders of the IRA interject that the IRA has only just come into effect. Cash from the IRA is only beginning to flow. And in an environment of higher costs for renewable energy equipment and higher interest rates, cash matters.

As Yakov Feygin put it: “Maybe the pithiest way to put it is that there are pre-IRA trends and outside IRA trends, but IRA has served to rapidly compress the timeframes for installation in a lot of technologies. So five years has turned into two, for example.”

So, to judge the impact of the IRA to date, the real question is not what has been built in 2022 and 2023, but what is in the pipeline.

Advised by JP Morgan, sophisticated global players like Ørsted are optimizing their use of both the production and investment tax credits offered by the IRA to launch large new renewable schemes. Of course, correlation is not the same as causation

Where the IRA is perhaps doing its most important work may be in incentivizing the middle bracket of projects where green momentum is less certain.

According to Utility Drive: “The 10 largest U.S. developers plan to build 110,364 MW of new wind and solar projects over the next five years, according to S&P Global Market Intelligence, but the majority of these projects remain in early stages of development. Just 15% of planned wind and solar projects are under construction, and 13% are considered to be in advanced stages of development, … ”

The states that I have highlighted in red stand out either for their unusually low existing level of renewable power capacity or their lack of current momentum.

Along with Texas, the pipelines for the PJM, MISO and Southeast regions (which includes Florida) look particularly healthy.

The relatively modest California numbers should not be a surprise. As Yakov Feygin and others pointed out, what is needed in California is not more raw generating capacity, but more battery storage. And that is what we are seeing in the data.

The numbers would be even larger if it were not for the truly surreal logjam in California’s system for authorizing interconnections. According to Hamilton/Brookings data the volume of hybrid solar and batter capacity in the queue for approval is 6.5 times the capacity currently operating in the state. In other words there is an entire energy transition waiting to happen when the overloaded managerial processes of the system catch up

Texas’s less bureaucratic system seems to be one of its key advantages in the extremely rapid roll-out of solar.

though it may be true that globally speaking the United States as a whole is a laggard in renewable energy development,

If California (with an economy roughly comparable to that of Germany at current exchange rates) and Texas (with an economy roughly the size of Italy’s) were countries, they would be #3 and #5 in the world in solar capacity per capita.

the obvious question is, which are the laggards in the US energy system.

So there is a lot to get excited about, at, what we are learning to call, the “meso”-level of the economy (more on this in a future post).

What the state-level data reveal is that there are a significant number of large states in the USA where solar and wind energy have barely made any impact. Pennsylvania, for instance

The relative levels of sunshine between US states is irrelevant. As the global solar atlas shows, the entire United States has far better solar potential than North West Europe. If you can grow corn and tobbaco, you can do utility-scale solar. The fact that Arizona is not a solar giant is mind boggling.

Texas is both big and truly remarkable. California already is a world leader in renewable energy. Meanwhile, the majority of the US electricity system presents a very different picture. There is a huge distance to be traveled and the pace of solar build-out is unremarkable.

This is where national level incentives like the IRA must prove themselves

And these local battles in America matter. Given the extremely high per capita energy consumption in the USA, greening state-level energy systems is significant at the global level. It does not compare to the super-sized levels of emissions in China, but it matters.

Indonesia’s total installed electricity generating capacity is rated at 81 GW. As far as immediate impact on the global carbon balance is concerned, cleaning up the power systems of Pennsylvania and Illinois would make an even bigger impact.

A key test of Biden-era climate and industrial policy will be whether it can untie the local political economy of fossil fuels, which, across many regions of the United States still stands in the way of a green energy transition that now has all the force of economics and technological advantage on its side.

One man, speaking about one of his favorite young influencers in a Telegram exchange captured by a child-safety activist, said that her mother knew “damn well” that many of her daughter’s followers were “pervy adult men.”

Meta looms over everything young influencers do on Instagram. It connects their accounts with strangers, and it can upend their star turns when it chooses. The company periodically shuts down accounts if it determines they have violated policies against child sexual exploitation or abuse. Some parents say their accounts have been shut down without such violations. 

Over the course of reporting this story, during which time the Journal inquired about the account the mom managed for her daughter, Meta shut down the account twice. The mom said she believed she hadn’t violated Meta’s policies. 

Meta’s guidance for content creators stresses the importance of engaging with followers to keep them and attract new ones. The hundreds of comments on any given post included some from other young fashion influencers, but also a large number of men leaving comments like “Gorgeous!” The mom generally liked or thanked them all, save for any that were expressly inappropriate. 

Meta spokesman Andy Stone said the company enables parents who run accounts for their children to control who is able to message them on Instagram or comment on their accounts. Meta’s guidance for creators also offers tips for building a safe online community, and the company has publicized a range of tools to help teens and parents achieve this.

Like many young girls, the daughter envied fashion influencers who made a living posting glamour content. When the mother agreed to help her daughter build her following and become an influencer, she set some rules. Her daughter wouldn’t be allowed to access the account or interact with anyone who sent messages. And they couldn’t post anything indicating exactly where they live. 

The mom stopped blocking so many users. Within a year of launching, the account had more than 100,000 followers. The daughter’s popularity earned her invitations to modeling events in big coastal cities where she met other young influencers. 

Social-media platforms have helped level the playing field for parents seeking an audience for their children’s talents. Instagram, in particular, is visually driven and easily navigable, which also makes it appealing for child-focused brands.

While Meta bans children under the age of 13 from independently opening social-media accounts, the company allows what it calls adult-run minor accounts, managed by parents. Often those accounts are pursuing influencer status, part of a burgeoning global influencer industry expected to be worth $480 billion by 2027, according to a recent Goldman Sachs report. 

Young influencers, reachable through direct messages, routinely solicit their followers for patronage, posting links to payment accounts and Amazon gift registries in their bios.

The Midwestern mom debated whether to charge for access to extra photos and videos via Instagram’s subscription feature. She said she has always rejected private offers to buy photos of her daughter, but she decided that offering subscriptions was different because it didn’t involve a one-on-one transaction.

The Journal asked Meta why it had at some points removed photos from the account. Weeks later, Meta disabled the account’s subscription feature, and then shut down the account without saying why. 

“There’s no personal connection,” she said. “You’re just finding a way to monetize from this fame that’s impersonal.”

The mom allowed the men to purchase subscriptions so long as they kept their distance and weren’t overtly inappropriate in messages and comments. “In hindsight, they’re probably the scariest ones of all,” she said. 

Stone, the Meta spokesman, said that the company will no longer allow accounts that primarily post child-focused content to offer subscriptions or receive gifts, and that the company is developing tools to enforce that.

he mom saw her daughter, though young, as capable of choosing to make money as an influencer and deciding when she felt uncomfortable. The mom saw her own role as providing the support needed for her daughter to do that.

The mom also discussed safety concerns with her now ex-husband, who has generally supported the influencer pursuit. In an interview, he characterized the untoward interest in his daughter as “the seedy underbelly” of the industry, and said he felt comfortable with her online presence so long as her mom posted appropriate content and remained vigilant about protecting her physical safety.

an anonymous person professing to be a child-safety activist sent her an email that contained screenshots and videos showing her daughter’s photos being traded on Telegram. Some of the users were painfully explicit about their sexual interest. Many of the photos were bikini or leotard photos from when the account first started.

Still, the mom realized she couldn’t stop men from trading the photos, which will likely continue to circulate even after her daughter becomes an adult. “Every little influencer with a thousand or more followers is on Telegram,” she said. “They just don’t know it.”

Early last year, Meta safety staffers began investigating the risks associated with adult-run accounts for children offering subscriptions, according to internal documents. The staffers reviewed a sample of subscribers to such accounts and determined that nearly all the subscribers demonstrated malicious behavior toward children.

The staffers found that the subscribers mostly liked or saved photos of children, child-sexualizing material and, in some cases, illicit underage-sex content. The users searched the platform using hashtags such as #sexualizegirls and #tweenmodel. 

The staffers found that some accounts with large numbers of followers sold additional content to subscribers who offered extra money on Instagram or other platforms, and that some engaged with subscribers in sexual discussions about their children. In every case, they concluded that the parents running those accounts knew that their subscribers were motivated by sexual gratification.

In the following months, the Journal began its own review of parent-run modeling accounts and found numerous instances where Meta wasn’t enforcing its own child-safety policies and community guidelines. 

The Journal asked Meta about several accounts that appeared to have violated platform rules in how they promoted photos of their children. The company deleted some of those accounts, as well as others, as it worked to address safety issues.

In 2022, Instagram started letting certain content creators offer paid-subscription services. At the time, the company allowed accounts featuring children to offer subscriptions if they were run or co-managed by parents.

The removal of the account made for a despondent week for the mom and daughter. The mother was incensed at Meta’s lack of explanation and the prospect that users had falsely reported inappropriate activity on the account. She was torn about what to do. When it was shut down, the account had roughly 80% male followers.

The account soon had more than 100,000 followers, about 92% of whom were male, according to the dashboard. Within months, Meta shut down that account as well. The company said the account had violated its policies related to child exploitation, but it didn’t specify how. 

Meta’s Stone said it doesn’t allow accounts it has previously shut down to resume the same activity on backup accounts. 

Du Bois’s quote, “Either the United States will destroy ignorance or ignorance will destroy the United States,” serves as a poignant reminder of the importance of education, understanding and open discourse in addressing societal challenges.

But while those are huge numbers by any measure (world GDP is around $100 trillion), they aren’t big enough to motivate most leaders to justify mitigation, which will also cost a whole lot of money.

To put it in terms the authors use, the recently enacted Inflation Reduction Act will cost Americans roughly $80 per ton of carbon emissions avoided, and while each ton not pumped into the atmosphere would save the world $200 as a whole, it would only save Americans about $40 of that $200, making it feel to some altruistic but not self-evident in purely economic terms.

In their new paper, economists Adrien Bilal of Harvard and Diego Känzig of Northwestern take a fresh look at the data

They show that the social cost of carbon is likely far bigger — six times bigger — than previously estimated: losses of more than $1,000 per ton, or around 12 percent of world GDP per degree of warming.

— roughly equivalent to the economic drag on big economies if they were permanently at war.

Suddenly, that $80 Americans are spending on reducing one ton of carbon emissions is netting them $200 or so in U.S. economic activity.

Bilal and Känzig argue that it’s very much worth it for countries of means to spend the money now to avoid much greater costs down the line

the potential losses are so vast it makes sense for these countries to go ahead and act on their own to avoid climate change losses, even if other nations do nothing.

What’s different about your methodology and how did it lead you to the numbers you've come up with?

Adrien Bilal: So virtually all of the previous work that's been done on the subject has relied on comparisons of different countries that heat up or cool down at different points in time. The U.K. gets a little hotter in one year, and then Germany stays cool. And then you look at how GDP in the U.K. evolves following that change in temperature.

that generally gives you numbers in the vicinity of $150 per ton of carbon emitted and a 2 percent decline in GDP per degree Celsius in warming

we think that is quite different from what climate change is actually doing to the world. It's not only that the U.K. is going to heat up a little more than Germany, but the whole world is heating up because of climate change. And, in particular, oceans are also heating up. And when the whole planet warms, that has potentially really different implications for the climate system, increased frequency of extreme weather events that then have big local impacts. 

that's actually what geoscientists have been telling us for a long time, but it simply hadn't percolated into economics. And so we took that perspective very seriously and thought, "Well, what happens when we basically compare years where the world is very hot to years where the world is cooler?" And that gives you a much larger effect of climate change on the economy.

All the old deficiencies and blind spots of male socialization are still in circulation — the same mass failure to teach boys relational skills and emotional intelligence, the same rigid masculinity norms and social prohibitions that push them away from intimacy and emotionality.

in many ways this environment has apparently had the opposite effect — it has shut them down even further.

The micro-generation that was just hitting puberty as the #MeToo movement exploded in 2017 is now of college (and voting) age. They have lived their whole adolescence not just in the digital era, with a glorious array of virtual options to avoid the angst of real-world socializing, but also in the shadow of a wider cultural reckoning around toxic masculinity.

We have spent the past half-decade wrestling with ideas of gender and privilege, attempting to challenge the old stereotypes and power structures. These conversations should have been an opportunity to throw out the old pressures and norms of manhood, and to help boys and men be more emotionally open and engaged.

in screen-addicted, culture war-torn America, we have also added new ones.

For many progressives, weary from a pileup of male misconduct, the refusal to engage with men’s feelings has now become almost a point of principle

For every right-wing tough guy urging his crying son to “man up,” there’s a voice from the left telling him that to express his concerns is to take airtime away from a woman or someone more marginalized

In many cases, the same people who are urging boys and men to become more emotionally expressive are also taking a moral stand against hearing how they actually feel

For many boys, it can seem as though their emotions get dismissed by both sides. This political isolation has combined with existing masculine norms to push a worrying number of boys into a kind of resentful, semi-politicized reclusion.

Over a quarter of men under 30 say they have no close friends

Teenage boys now spend two hours less a week socializing than girls and they also spend about seven hours more per week than their female peers on screens.

my own research has fed my fears.

the same theme came up over and over for boys who on the face of it had little else in common. They were lonely.

almost all of them had the nagging sense that something important was missing in those friendships. They found it almost impossible to talk to their male peers about anything intimate or express vulnerability.

One teenager described his social circle, a group of boys who had been best friends since kindergarten, as a “very unsupportive support system.” Another revealed that he could recall only one emotionally open conversation with a male friend in his life, and that even his twin brother had not seen him cry in years

they felt unable to articulate this pain or seek help, because of a fear that, because they were boys, no one would listen.

As one 20-year-old put it, “If a man voices any concern, they get deflected with all of their so-called privileges.” He added: “They’d be like, ‘Whatever. Women have suffered more than you, so you have no right to complain.’”

Almost without exception, the boys I talked to craved closer, more emotionally open relationships, but had neither the skills nor the social permission to change the story.

Perhaps it’s not surprising that boys don’t know how to listen and engage with their friends’ emotions on any deeper level; after all, no one really engages with theirs.

in a sexist society, male opinions hold outsized value. But the world — including their own parents — has less time for their feelings.

One study from 2014 showed that parents were more likely to use emotional words when talking with their 4-year-old daughters than those speaking to their 4-year-old sons.

A more recent study comparing fathers of boys with fathers of girls found that fathers of boys were less attentively engaged with their boys, spent less time talking about their son’s sad feelings and instead were more likely to roughhouse with them. They even used subtly different vocabularies when talking with boys, with fewer feelings-centered words, and more competition and winning-focused language.

Spend any time in the manosphere, and it’s easy to start to hate men and boys. The extreme misogyny, the gleeful hate speech, the violent threats and thrum of menace make it hard to summon much sympathy for male concerns, and easy to forget the ways that patriarchy harms them, too.

in the grip of the culture wars, caring about boys has become subtly coded as a right-wing cause,

Men have had way more than their fair share of our concern already, the reasoning goes, and now it’s time for them to pipe down

But for boys, privilege and harm intertwine in complex ways — male socialization is a strangely destructive blend of indulgence and neglect. Under patriarchy, boys and men get everything, except the thing that’s most worth having: human connection.

The prescription for creating a generation of healthier, more socially and emotionally competent men is the same in the wider political discourse as it is in our own homes — to approach boys generously rather than punitively

We need to acknowledge boys’ feelings, to talk with our sons in the same way we do our daughters, to hear them and empathize rather than dismiss or minimize, and engage with them as fully emotional beings.

The root causes of silence are not social solidarity but fear and futility. People bite their tongues when they doubt that it’s safe and worthwhile to speak up. Leaders who want to make informed decisions need to make it clear they value candid input.

Mr. Biden has done the opposite, declaring first that only the Lord almighty could change his mind and then saying that he’ll drop out only if polls say there’s no way for him to win. That sends a strong message

If you’re not an immortal being or a time traveler from the future, it’s pointless to share any concerns about the viability of his candidacy.

I’ve reminded them that they’re lucky to have a president who doesn’t punish dissenters with an indefinite prison sentence or a trial for treason. That diffusion of responsibility is a recipe for groupthink — if everyone leaves it to someone else, no one will end up speaking up.

Although it can help to assign devil’s advocates, it’s more effective to unearth them. Genuine dissenters argue more convincingly and get taken more seriously.

It’s time for Mr. Biden’s team to run an anonymous poll of advisers, governors and lawmakers. The results of the poll could be given to an honest broker — someone with a vested interest in winning the election rather than appeasing the president

To avoid pressure from the top, I might try a fishbowl format, asking Mr. Biden to listen first and speak last.

Over the past week, I’ve raised these ideas with several leaders close to the president who reached out for advice. They’ve each made it clear that they’re afraid to put their relationship on the line and they don’t think Mr. Biden will listen to them

Showing openness can raise people’s confidence, but it’s not always enough to quell their fear. In our research, Constantinos Coutifaris and I found that it helps for leaders to criticize themselves out loud. That way, instead of just claiming that they want the truth, they can show that they can handle the truth.

“President Biden, I know you believe that politicians shouldn’t let hubris cloud their judgment. I’m worried that people are telling you what you want to hear, not what you need to hear. We know the good things that could happen if you run and win, but we also need to discuss the good things that could happen if you don’t run. You could be hailed as a hero like George Washington for choosing not to seek another term. Regardless of the result, you could make history through your selfless stewardship of the next generation. Personally, I don’t know if that’s the right decision. I just want to make sure it gets due consideration. Would you be open to hosting a meeting to hear the dissenting views?

AlphaGo’s victory demonstrated the unbridled potential of A.I. to achieve superhuman mastery of skills once considered too complicated for machines.

Mr. Lee, now 41, retired three years later, convinced that humans could no longer compete with computers at Go. Artificial intelligence, he said, had changed the very nature of a game that originated in China more than 2,500 years ago.

As society wrestles with what A.I. holds for humanity’s future, Mr. Lee is now urging others to avoid being caught unprepared, as he was, and to become familiar with the technology now. He delivers lectures about A.I., trying to give others the advance notice he wishes he had received before his match.

“I faced the issues of A.I. early, but it will happen for others,” Mr. Lee said recently at a community education fair in Seoul to a crowd of students and parents. “It may not be a happy ending.”

Mr. Lee is not a doomsayer. In his view, A.I. may replace some jobs, but it may create some, too. When considering A.I.’s grasp of Go, he said it was important to remember that humans both created the game and designed the A.I. system that mastered it.

What he worries about is that A.I. may change what humans value.

His immense talent was apparent from the start. He quickly became the best player of his age not only locally but across all of South Korea, Japan and China. He turned pro at 12.

“People used to be in awe of creativity, originality and innovation,” he said. “But since A.I. came, a lot of that has disappeared.”

By the time he was 20, Mr. Lee had reached 9-dan, the highest level of mastery in Go. Soon, he was among the best players in the world, described by some as the Roger Federer of the game.

Go posed a tantalizing challenge for A.I. researchers. The game is exponentially more complicated than chess, with it often being said that there are more possible positions on a Go board (10 with more than 100 zeros after it, by many mathematical estimates) than there are atoms in the universe.

The breakthrough came from DeepMind, which built AlphaGo using so-called neural networks: mathematical systems that can learn skills by analyzing enormous amounts of data. It started by feeding the network 30 million moves from high-level players. Then the program played game after game against itself until it learned which moves were successful and developed new strategies.

Mr. Lee said not having a true human opponent was disconcerting. AlphaGo played a style he had never seen, and it felt odd to not try to decipher what his opponent was thinking and feeling. The world watched in awe as AlphaGo pushed Mr. Lee into corners and made moves unthinkable to a human player.“I couldn’t get used to it,” he said. “I thought that A.I. would beat humans someday. I just didn’t think it was here yet.”

AlphaGo’s victory “was a watershed moment in the history of A.I.” said Demis Hassabis, DeepMind’s chief executive, in a written statement. It showed what computers that learn on their own from data “were really capable of,” he said.

Mr. Lee had a hard time accepting the defeat. What he regarded as an art form, an extension of a player’s own personality and style, was now cast aside for an algorithm’s ruthless efficiency.

His 17-year-old daughter is in her final year of high school. When they discuss what she should study at university, they often consider a future shaped by A.I.“We often talk about choosing a job that won’t be easily replaceable by A.I. or less impacted by A.I.,” he said. “It’s only a matter of time before A.I. is present everywhere.”
