We tend to take it for granted, but it is an astonishing novelty in human history. For thousands of years, military expenditure was by far the biggest item on the budget

The decline of war didn’t result from a divine miracle or from a change in the laws of nature. It resulted from humans making better choices. It is arguably the greatest political and moral achievement of modern civilisation.

he fact that it stems from human choice also means that it is reversible.

Technology, economics and culture continue to change. The rise of cyber weapons, AI-driven economies and newly militaristic cultures could result in a new era of war, worse than anything we have seen befor

Maybe the law of the jungle is a choice rather than an inevitability?

a poor choice by just one side can lead to war.

To enjoy peace, we need almost everyone to make good choice

The first and most obvious result of a return to the law of the jungle would be a sharp increase in military spending at the expense of everything else

A return to the jungle would also undermine global co-operation on problems such as preventing catastrophic climate change or regulating disruptive technologies such as artificial intelligence and genetic engineering.

If you believe that historic change is impossible, and that humanity never left the jungle and never will, the only choice left is whether to play the part of predator or prey.

This is why the Russian threat to invade Ukraine should concern every person on Earth

If so, any leader who chooses to conquer a neighbour will get a special place in humanity’s memory, far worse than your run-of-the-mill Tamerlane. He will go down in history as the man who ruined our greatest achievement

perhaps we can learn from the Ukrainians.

They endured two centuries of tsarist autocracy (which finally collapsed amidst the cataclysm of the first world war). A brief attempt at independence was quickly crushed by the Red Army that re-established Russian rule. Ukrainians then lived through the terrible man-made famine of the Holodomor, Stalinist terror, Nazi occupation and decades of soul-crushing Communist dictatorship. When the Soviet Union collapsed, history seemed to guarantee that Ukrainians would again go down the path of brutal tyranny – what else did they know?

Despite history, despite grinding poverty and despite seemingly insurmountable obstacles, Ukrainians established a democracy. In Ukraine, unlike in Russia and Belarus, opposition candidates repeatedly replaced incumbents

Every old thing was once new. It all comes down to human choices

Even during the 2022 campaign, when Biden regularly framed Republicans as a threat to voting and abortion rights, he did not highlight red-state book bans and curriculum censorship. Apart from abortion and voting, his inclination has been to focus his public communications less on culture-war disputes than on delivering kitchen-table benefits to working families

One senior adviser close to Biden told me that the connection of book bans to those more frequent presidential targets of abortion and democracy was no accident. “There is a basic American pushback when people are told what they can and cannot do,” said the adviser, who asked for anonymity while discussing campaign strategy. “Voters,” the adviser said, “don’t like to be told, ‘You can’t make a decision about your own life when it comes to your health care; you can’t make a decision about what book to read.’ I think book bans fit in that broader context.”

His statement came months after the department’s Office of Civil Rights launched an investigation that could shape the next stages of this struggle. The office is probing whether a Texas school district that sweepingly removed LGBTQ-themed books from its shelves has violated federal civil-rights laws. The department has not revealed anything about the investigation’s status, but PEN’s Farid Johnson said if it concludes that the removals violated federal law, other districts might be deterred from banning books.

The politics of the parents’-rights debate are complex. Republicans are confident that their interconnected initiatives related to education and young people can win back suburban voters, especially mothers, who have rejected the party in the Trump era. Polling, including surveys done by Democratic pollsters last year for the American Federation of Teachers, has consistently found majority national support for some individual planks in the GOP agenda, including the prohibitions on discussing sexual orientation in early grades.

“We shouldn’t expect a national consensus on what book is appropriate for a 13-year-old to be reading, because that’s going to be different among different parents in different communities,”

Yet as the awakening Democratic resistance suggests, many in the party are confident that voters will find the whole of the GOP agenda less attractive than the sum of its parts. In that 2022 polling for the teachers’ union, a significant majority of adults said they worry less that kids are being taught values their parents don’t like than that culture-war fights are diverting schools from their real mission of educating students.

the most common complaint she hears from women drawn to her group is that the conservative activists proclaiming parents’ rights are curtailing the freedoms of other parents by trying to dictate what materials all students can access. “What you’ll have women in our communities say all the time is ‘If you don’t want your kid to read a book, that’s fine, but you don’t get to decide for me and my family,’” she told me

“I want this trial to be seen by everybody in the world,” Mr. Trump said to a cheering crowd, referring to his federal election trial in Washington. “The prosecution wishes to continue this travesty in darkness, and I want sunlight.”

As he has before, Mr. Trump again called for executing drug dealers, praising China for making drug trafficking a capital offense. But in New Hampshire, a state where the opioid crisis has hit particularly hard, he turned to an informal straw poll to strengthen his case.

“Let’s have a vote,” Mr. Trump said to the crowd. “Who would be in favor of the death penalty — now, wait, don’t go yet — knowing that it will solve the problem?”

Mr. Trump also repeated lies, falsehoods, exaggerations and half-truths that he has told routinely on a number of subjects, including on gas prices, U.S. energy independence, election fraud and the 2020 elections.“I’m a very proud election denier,”

And he complimented President Xi Jinping of China, of whom he said, “He’s like Central Casting. There’s nobody in Hollywood that can play the role of President Xi — the look, the strength, the voice.”

As long as life continues as it has — with people choosing smaller family sizes, as is now common in most of the world — then in the 22nd or 23rd century, our decline could be just as steep as our rise.

there is no consensus on exactly how quickly populations will fall after that. Over the past 100 years, the global population quadrupled, from two billion to eight billion.

What would happen as a consequence? Over the past 200 years, humanity’s population growth has gone hand in hand with profound advances in living standards and health: longer lives, healthier children, better education, shorter workweeks and many more improvements

In this short period, humanity has been large and growing. Economists who study growth and progress don’t think this is a coincidence. Innovations and discoveries are made by people. In a world with fewer people in it, the loss of so much human potential may threaten humanity’s continued path toward better lives.

It would be tempting to welcome depopulation as a boon to the environment. But the pace of depopulation will be too slow for our most pressing problems. It will not replace the need for urgent action on climate, land use, biodiversity, pollution and other environmental challenges

If the population hits around 10 billion people in the 2080s and then begins to decline, it might still exceed today’s eight billion after 2100

Population decline would come quickly, measured in generations, and yet arrive far too slowly to be more than a sideshow in the effort to save the planet. Work to decarbonize our economies and reform our land use and food systems must accelerate in this decade and the next, not start in the next century.

This isn’t a call to immediately remake our societies and economies in the service of birthrates. It’s a call to start conversations now, so that our response to low birthrates is a decision that is made with the best ideas from all of u

If we wait, the less inclusive, less compassionate, less calm elements within our society and many societies worldwide may someday call depopulation a crisis and exploit it to suit their agendas — of inequality, nationalism, exclusion or control

Births won’t automatically rebound just because it would be convenient for advancing living standards or sharing the burden of care work

We know that fertility rates can stay below replacement because they have. They’ve been below that level in Brazil and Chile for about 20 years; in Thailand for about 30 years; and in Canada, Germany and Japan for about 50.

In fact, in none of the countries where lifelong fertility rates have fallen well below two have they ever returned above it. Depopulation could continue, generation after generation, as long as people look around and decide that small families work best for them, some having no children, some having three or four and many having one or two.

Nor can humanity count on any one region or subgroup to buoy us all over the long run. Birthrates are falling in sub-Saharan Africa, the region with the current highest average rates, as education and economic opportunities continue to improve

The main reason that birthrates are low is simple: People today want smaller families than people did in the past. That’s true in different cultures and economies around the world. It’s what both women and men report in surveys.

Humanity is building a better, freer world with more opportunities for everyone, especially for women

That progress also means that, for many of us, the desire to build a family can clash with other important goals, including having a career, pursuing projects and maintaining relationships

In a world of sustained low birthrates and declining populations, there may be threats of backsliding on reproductive freedom — by limiting abortion rights, for example

Nobody yet knows what to do about global depopulation. But it wasn’t long ago that nobody knew what to do about climate change. These shared challenges have much in common,

As with climate change, our individual decisions on family size add up to an outcome that we all share.

Six decades from now is when the U.N. projects the size of the world population will peak. There won’t be any quick fixes: Even if it’s too early today to know exactly how to build an abundant future that offers good lives to a stable, large and flourishing future population, we should already be working toward that goal.

The national unemployment rate, as calculated by the National Bureau of Statistics, accounts only for urban unemployment, which stands at just above 5 percent and is believed to be underestimated. The average monthly income of migrant workers was $630 in 2022, or less than half the income of those working for the government. And that data is flawed because it includes only months when a worker has a job.

Mr. Xi said in his speech that the mass return of migrant workers in 2008 and 2020 had not caused any social problems because they “have land and houses back in their home villages so they can return to cultivate the land, have food to eat, and work on something.”

But the prospect of moving back to the villages is often bleak and even scary, especially for younger migrant workers who have spent their adult lives in the cities. They can see what awaits them. Their parents and grandparents may need to work until they physically cannot anymore and hesitate to seek medical care. They usually do not have unemployment benefits, and they cannot rely on their families, as some urban youths do, because their parents’ and grandparents’ pensions are “only enough to buy salt,

The other reality facing migrant workers is that returning to their villages to earn money farming is not an option, as Mr. Xi said it was. There is not enough land waiting for them

“For Chinese, especially in the countryside, there’s no such thing called retirement,” he said. His grandfather is 90 and cleans pig manure for a farm every day in the central province of Henan.

The morning we spoke he had just gotten off a shift that started at 7:30 p.m. and ended at 7 a.m. He had worked for two weeks without a day off because of the demand for Apple’s newest iPhone.

He feels he cannot go home to his village and do nothing while his parents and grandfather are still working. “It’s just not appropriate,”

“My ideal country is one where the people live in peace and prosperity, where there is food safety, freedom of speech, justice, a media that can expose injustices, a five-day, eight-hour workweek for workers,” said Mr. Zhang, the unemployed welder. “If these can be achieved, I will support whoever is in power, regardless of their party or how long they govern.”

Mr. Ge left his village at age 17 and started working on construction sites and in factories. He had benefits during the six years he worked at Foxconn, a contract manufacturer for Apple. But when he was out of work this year, he could not get any unemployment benefits, which is not uncommon as local governments are deeply in debt. Now 34, he still works 10-hour shifts at another Apple contract manufacturer and lives in a dormitory.

“Only people who couldn’t find jobs would do farming,” said Guan, a migrant worker in the northwestern province of Gansu, “because income from farming is too low.”

“To be honest, deep down I feel lost,” he said. “All I can say is that for the time being, I’ll save as much money as possible. As for what the future holds, it’s really hard to say. I might not even live to see that age.”

One side of American politics considers the modern welfare state — a private-enterprise economy, but one in which society’s winners are taxed to pay for a social safety net — morally superior to the capitalism red in tooth and claw we had before the New Deal. It’s only right, this side believes, for the affluent to help the less fortunate.

This deep divide in American political morality — for that’s what it amounts to — is a relatively recent development. Commentators who pine for the days of civility and bipartisanship are, whether they realize it or not, pining for the days when the Republican Party accepted the legitimacy of the welfare state, and was even willing to contemplate expanding it.

we have, for the most part, managed to agree on certain ground rules in the abortion controversy: it’s acceptable to express your opinion and to criticize the other side, but it’s not acceptable either to engage in violence or to encourage others to do so. What we need now is an extension of those ground rules to the wider national debate.

When people talk about partisan differences, they often seem to be implying that these differences are petty, matters that could be resolved with a bit of good will. But what we’re talking about here is a fundamental disagreement about the proper role of government.

Today’s G.O.P. sees much of what the modern federal government does as illegitimate; today’s Democratic Party does not

This deep divide in American political morality — for that’s what it amounts to — is a relatively recent development.

There’s no middle ground between these views. One side saw health reform, with its subsidized extension of coverage to the uninsured, as fulfilling a moral imperative: wealthy nations, it believed, have an obligation to provide all their citizens with essential care

The other side saw the same reform as a moral outrage, an assault on the right of Americans to spend their money as they choose.

We need to have leaders of both parties — or Mr. Obama alone if necessary — declare that both violence and any language hinting at the acceptability of violence are out of bounds. We all want reconciliation, but the road to that goal begins with an agreement that our differences will be settled by the rule of law.

Think about the lives lost.Think about the teachers.Think about the children.They were family, friends, and loved ones.And a gun killed them all.It was only last week that we posted a similar prompt in response to the racist massacre in Buffalo. Like all of our student forums, this one will be moderated.

Students might find their own ways to respond, perhaps through writing or art. It may also be helpful to look at how victims of other tragedies have been memorialized, in ways big and small. For example: The 26 playgrounds built to remember the children of Sandy Hook; the memorial for the Oklahoma City bombing, with its “field of chairs,” including 19 smaller ones for the children who lost their lives; and the New York Times Portraits of Grief series, which profiled those lost in the Sept. 11 terrorist attacks. Here are more examples, from the El Paso Times. In what ways can your students or school respond, individually or collectively?

What is it like to be a student in the shadow of this violence? How have repeated mass shootings shaped young people? We invite your students to reflect on these questions in this writing prompt, and post their answers to our forum if they would like to join a public conversation on the topic.To help students think about the issue from different angles, we invite them to read the article “A ‘Mass Shooting Generation’ Cries Out for Change,” which was published in 2018 following the shooting at Marjory Stoneman Douglas High School in Parkland, Fla. Then we ask questions such as:

The authors of the 2018 Times article described how the Parkland shooting moved students around the country to become more involved in activism. Do you think something similar will happen in the wake of the shooting in Uvalde, Texas? Why or why not? How do you think school shootings are shaping the generation of students who are in school right now?Invite your students to weigh in here.

Democrats moved quickly to clear the way for votes on legislation to strengthen background checks for gun purchasers. Republicans, even as they expressed horror about the shooting, did not signal that they would drop their longstanding opposition to gun safety measures. Gov. Greg Abbott of Texas pointed the blame at Uvalde’s lack of mental health care, even though the suspect had no record of problems.

Which efforts might be the most effective? Students might also take a look at the forum on guns we posted during the 2016 election as part of our Civil Conversation Challenge in which we invited teenagers to have productive, respectful conversations on several issues dividing Americans. We received more than 700 responses to the questions we posed about gun rights, the Second Amendment and more.

This article takes on three of the most prominent rumors that have spread via online platforms such as Twitter, Gab, 4chan and Reddit and explains why they are false. What rumors are your students seeing in their feeds, and what steps can they take to find out the truth? From double-checking via sites like Snopes to learning habits like lateral reading, this article (and related lesson plan) has suggestions.

While the town of Uvalde grapples with the aftermath of the shooting, community members, local leaders and organizations have mobilized. Two local funeral homes said in social media posts that they would not charge families of victims for their funeral services. Volunteers have lined up to give blood for the shooting victims.

If Putin defeats the Ukrainians, the conservatives that are standing against Putin will look ineffectual and weak. The Trumpists will then be able to solidify their control over the GOP.

Meanwhile, on the Democratic side, the socialist Left that started to revive itself with the antiwar movement and Occupy blossomed into a full-blown generational movement with the 2016 Bernie Sanders campaign that revived the DSA, spawned a new generation of activist orgs like the Sunrise movement, and created a new (though still modest) socialist medi

So far, despite fierce factionalism, the socialists have not yet succeeded in taking over the Democratic party like Trump took over the GOP. But in highlighting the failures of centrist Dems to curb inequality, revive unions, fix health care, or save the welfare state, they clearly hope to be able to pull off a takeover at some point.

Establishment failures equal insurgent opportunities. That shouldn’t be too controversial.

Both the liberal center-Left and the conservative center-Right are basically committed to upholding the global liberal order. Putin, by invading and attempting to conquer a sovereign state, challenges that order. If Putin succeeds, even modestly, it represents a failure for the U.S. establishment figures who tried to stop him.

It was the failure of conservatism that gave rise to the Trumpist movement and the alt-right. Bush’s muscular interventionism ran aground in Iraq, laissez-faire economics crashed the economy in 2008, and Christian conservatism failed to halt the gay rights movement. The conservative paradigm that had taken over the GOP in the 70s and 80s failed all at once, and fringe elements — the alt-right, conspiracy theorists, Trump — sort of took over the party.

it also means a victory for raw power and will (perhaps implying that efforts like the January 6th putsch are the preferred method for attaining power).

But if Putin loses, then Trump and his allies who for years praised and defended Putin’s regime will be discredited. Success has a thousand fathers; failure is an orphan.

Even more damningly, if Putin loses, it’ll be a success for the globalist order — sanctions and aid to Ukraine will represent a triumph of international cooperation. Exactly the kind of world order the Trumpists want so badly to smash.

If Putin defeats Ukraine, it’ll be a debacle for Biden and the establishment, and perhaps a socialist candidate will be a little closer to winning the next primary.

So Chaos Climbers on the Right and Left both have some incentive to want Putin to win — or at least for the war to be perceived as a NATO loss.

What these people all fear is the return of the order of the 1990s — a return to the idea of liberal internationalism as the least bad of all possible systems of human organization.

many people all over the ideological spectrum allowed themselves to see the chaos of the last decade as a high and beautiful wave that would carry them to power…and now, if Putin is ejected from Ukraine by a triumphant international liberal West, the various Chaos Climbers may see their waves break and roll back.

It often borrows the language of social justice movements

BimboTok came about at a time when the girlboss had more or less faded as a trendy cultural type

“I don’t know what the economy is, I don’t know what supply and demand is,” Ms. Chlapecka says in one video. “All I know is that our problems would be solved if we’d just print more money.” There’s a way in which her monologues can come to feel almost incisive — why can’t we print more money? The answer is complicated, obviously, and on some level Ms. Chlapecka knows that. “I’m asking a lot of questions that, yes, I have the answer to, but are also valid,” she said. “The whole world we made is literally made up, so we can make up solutions to the issues we have.”

Bimboism is the antithesis of the mode of feminism that was dominant in the 2010s, a kind of hyperambitious you-can-have-it-all feminism that can be summed up by the label “girlboss.”

It encourages asking the dumb questions that get to the heart of things.

Amid the resurgence of leftist politics, and the disillusionment with capitalism among millennials and Gen Z, the framing of careerism and individualism as feminist rings hollow

That girlboss model was critiqued for its lack of inclusivity — its overwhelming whiteness and its focus on a level of economic success that was never attainable for a vast majority of women.

Not to mention, girlboss aesthetics are simply cringe, for a generation steeped in internet irony.

In its most interesting form, bimboism also makes a connection between the ideas of pleasure — sexual pleasure, pleasure in clothes, pleasure in simply existing as a woman in the world with a body on display — and political gains that would make it more possible, like universal health care, student loan debt cancellation and abortion rights.

It’s anticapitalist, even anti-work. (In one video, another BimboTok comedian, @brattybarbiana, dances behind text that reads, “Rule of thumb: All relationships should be 50/50 … He works for his money, I spend it!”)

Bimboism offers an opposing and, to some, refreshing premise: Value me, look at me, not because I’m smart and diligent, but for the fact that I’m not.

But to dismiss this corner of the internet as totally backward would be to miss the point.

Is it really leftist for a woman to want to just go shopping and never get a job?

“Are you a leftist who likes to have their tits out? Do you like to flick off pro-lifers?” Chrissy Chlapecka asks the camera in a 51-second TikTok captioned “BIMBOS, RISE

This is a delayed but inescapable consequence of China’s birth trends from the era of the notorious one-child policy (1980-2015)

Beijing thus far has ignored this looming crisis because planners don’t prepare for things they don’t track. Officials don’t regard data on the family as relevant to statecraft or security. So statistics tally males and females—not uncles, sisters, cousins, widows.

We estimate past patterns and project trends through demographic modeling—simulations replicating China’s available population numbers—while “building” family trees consistent with those figures. We can approximate nationwide changes in China’s extended family networks in the past with reasonable validity and describe what lies ahead with fair confidence.

we are only now living through the era of “peak kin” in China. In terms of sheer numbers, Chinese networks of blood relatives were never nearly as thick as at the start of the 21st century.

Because of dramatic postwar improvements in health and mortality, men and women in their 40s today have on average five times as many living cousins as in 1960.

China’s “kin explosion” may be an important, heretofore unobserved factor in China’s remarkable economic performance since Mao Zedong’s death in 1976.

China is now on the cusp of a severe and unavoidable “kin crash,” driven by prolonged subreplacement fertility

China’s rising generations will likely have fewer living relatives than ever before in Chinese history.

A “kin famine” will thus unfold unforgivingly over the next 30 years—starting now. As it intensifies, the Chinese family—the most important institution protecting Chinese people against adversity in bad times and helping them seize opportunity in good times—will increasingly falter in both these crucial functions.

China’s withering of the family is set to collide with a tsunami of new social need from the country’s huge elderly population, whose ranks will more than double between 2020 and 2050

By 2050 living parents and in-laws will outnumber children for middle-aged Chinese men and women. Thus exigency may overturn basic familial arrangements that have long been taken for granted. The focus of the family in China will necessarily turn from the rearing of the young to the care of the old.

The reliability and durability of familial bonds of duty will be an increasingly critical question—perhaps even a matter of life and death for many, including frail and impecunious elders in the Chinese hinterlands

growing numbers of men in decades ahead will enter old age without spouses or children—the traditional sources of support for the elderly.

by 2050, 18% of China’s men in their 60s will have no living descendants, twice the fraction today.

who will look after these unfortunates?

Still worse than the macroeconomic implications of old-age dependency may be the effect of China’s family crisis on the so-called micro-foundations of the national economy—the little things that make markets work.

Since earliest recorded history, China’s guanxi networks, a distinctive form of special relationships and professional connections, have helped get business done by reducing uncertainty and transaction costs. The proliferation of blood relatives was likely a powerful stimulant for growth during the era of China’s phenomenal upswing.

the kin dearth may prove an economic depressant well beyond what current “head count” projections suggest.

China’s coming family revolution could easily conduce to a rise in personal risk aversion. Risk aversion may in turn dampen mobility, including migration.

Less migration means less urbanization, which means less growth—and possibly still more pessimism and risk aversion.

If the waning of the family requires China to build a huge social welfare state over the coming generation, as we surmise it will, Beijing would have that much less wherewithal for influencing events abroad through economic diplomacy and defense policy.

by 2050 at least half of China’s overall pool of male military-age manpower will be made up of only children. Any encounter by China’s security forces involving significant loss of life will presage lineage extinction for many Chinese families.

Autocracies are typically tolerant of casualties—but maybe not in the only-child China of today and the decades ahead.

Failure to contemplate the implications of the coming changes in Chinese family structure could prove a costly blind spot for the Communist Party. Blind spots expose governments to the risk of strategic surprise. The consequences of social, economic and political risks tend to be greatest when states aren’t prepared for them.

To the uninitiated, the fact that Bankman-Fried saw a special urgency in preventing killer robots from taking over the world might sound too outlandish to seem particularly effective or altruistic. But it turns out that some of the most influential E.A. literature happens to be preoccupied with killer robots too.

Holden Karnofsky, a former hedge funder and a founder of GiveWell, an organization that assesses the cost-effectiveness of charities, has spoken about the need for “worldview diversification” — recognizing that there might be multiple ways of doing measurable good in a world filled with suffering and uncertainty

The books, however, are another matter. Considerations of immediate need pale next to speculations about existential risk — not just earthly concerns about climate change and pandemics but also (and perhaps most appealingly for some tech entrepreneurs) more extravagant theorizing about space colonization and A.I.

there’s a remarkable intellectual homogeneity; the dominant voices belong to white male philosophers at Oxford.

Among his E.A. innovations has been the career research organization known as 80,000 Hours, which promotes “earning to give” — the idea that altruistic people should pursue careers that will earn them oodles of money, which they can then donate to E.A. causes.

each of those terse sentences glosses over a host of additional questions, and it takes MacAskill an entire book to address them. Take the notion that “future people count.” Leaving aside the possibility that the very contemplation of a hypothetical person may not, for some real people, be “intuitive” at all, another question remains: Do future people count for more or less than existing people count for right now?

MacAskill cites the philosopher Derek Parfit, whose ideas about population ethics in his 1984 book “Reasons and Persons” have been influential in E.A. Parfit argued that an extinction-level event that destroyed 100 percent of the population should worry us much more than a near-extinction event that spared a minuscule population (which would presumably go on to procreate), because the number of potential lives dwarfs the number of existing ones.

If you’re a utilitarian committed to “the greatest good for the greatest number,” the arithmetic looks irrefutable. The Times’s Ezra Klein has written about his support for effective altruism while also thoughtfully critiquing longtermism’s more fanatical expressions of “mathematical blackmail.”

In 2015, MacAskill published “Doing Good Better,” which is also about the virtues of effective altruism. His concerns in that book (blindness, deworming) seem downright quaint when compared with the astral-plane conjectures (A.I., building an “interstellar civilization”) that he would go on to pursue in “What We Owe the Future.”

In both books he emphasizes the desirability of seeking out “neglectedness” — problems that haven’t attracted enough attention so that you, as an effective altruist, can be more “impactful.” So climate change, MacAskill says, isn’t really where it’s at anymore; readers would do better to focus on “the issues around A.I. development,” which are “radically more neglected.

In his recent best seller, “What We Owe the Future” (2022), MacAskill says that the case for effective altruism giving priority to the longtermist view can be distilled into three simple sentences: “Future people count. There could be a lot of them. We can make their lives go better.”

“Earning to give” has its roots in the work of the radical utilitarian philosopher Peter Singer, whose 1972 essay “Famine, Affluence and Morality” has been a foundational E.A. text. It contains his parable of the drowning child: If you’re walking past a shallow pond and see a child drowning, you should wade in and save the child, even if it means muddying your clothes

Extrapolating from that principle suggests that if you can save a life by donating an amount of money that won’t pose any significant problems for you, a decision not to donate that money would be not only uncharitable or ungenerous but morally wrong.

Singer has also written his own book about effective altruism, “The Most Good You Can Do” (2015), in which he argues that going into finance would be an excellent career choice for the aspiring effective altruist. He acknowledges the risks for harm, but he deems them worth it

Chances are, if you don’t become a charity worker, someone else will ably do the job; whereas if you don’t become a financier who gives his money away, who’s to say that the person who does become a financier won’t hoard all his riches for himself?

On Nov. 11, when FTX filed for bankruptcy amid allegations of financial impropriety, MacAskill wrote a long Twitter thread expressing his shock and his anguish, as he wrestled in real time with what Bankman-Fried had wrought.

“If those involved deceived others and engaged in fraud (whether illegal or not) that may cost many thousands of people their savings, they entirely abandoned the principles of the effective altruism community,” MacAskill wrote in a Tweet, followed by screenshots from “What We Owe the Future” and Ord’s “The Precipice” that emphasized the importance of honesty and integrity.

I’m guessing that Bankman-Fried may not have read the pertinent parts of those books — if, that is, he read any parts of those books at all. “I would never read a book,” Bankman-Fried said earlier this year. “I’m very skeptical of books. I don’t want to say no book is ever worth reading, but I actually do believe something pretty close to that.”

Avoiding books is an efficient method for absorbing the crudest version of effective altruism while gliding past the caveats

For all of MacAskill’s galaxy-brain disquisitions on “A.I. takeover” and the “moral case for space settlement,” perhaps the E.A. fixation on “neglectedness” and existential risks made him less attentive to more familiar risks — human, banal and closer to home.

it is easy to forget how much we have in common as people. I can’t think of any major nation after the United States with more of a Protestant work ethic and naturally capitalist population than China.

These days, it is extremely difficult for a visiting columnist to get anyone — a senior official or a Starbucks barista — to speak on the record. It was not that way a decade ago.

The Communist Party’s hold is also a product of all the hard work and savings of the Chinese people, which have enabled the party and the state to build world-class infrastructure and public goods that make life for China’s middle and lower classes steadily better.

Beijing and Shanghai, in particular, have become very livable cities, with the air pollution largely erased and lots of new, walkable green spaces.

some 900 cities and towns in China are now served by high-speed rail, which makes travel to even remote communities incredibly cheap, easy and comfortable

Just when trust has become more important than ever between the U.S. and China, it also has become scarcer than ever. Bad trend.

China’s stability is a product of both an increasingly pervasive police state and a government that has steadily raised standards of living. It’s a regime that takes both absolute control and relentless nation-building seriously.

For an American to fly from New York’s Kennedy Airport into Beijing Capital International Airport today is to fly from an overcrowded bus terminal to a Disney-like Tomorrowland.

China got an early jump on A.I. in two realms — facial recognition technology and health records — because there are virtually no privacy restrictions on the government’s ability to build huge data sets for machine learning algorithms to find patterns.

“ChatGPT is prompting some people to ask if the U.S. is rising again, like in the 1990s,”

“I understand your feeling: You have been in the first place for a century, and now China is rising, and we have the potential to become the first — and that is not easy for you,” Hu said to me. But “you should not try to stop China’s development. You can’t contain China in the end. We are quite smart. And very diligent. We work very hard. And we have 1.4 billion people.”

Before the Trump presidency, he added: “We never thought China-U.S. relations would ever become so bad. Now we gradually accept the situation, and most Chinese people think there is no hope for better relations. We think the relationship will be worse and worse and hope that war will not break out between our two countries.”

A lot of people hesitated when I asked. Indeed, many would answer with some version of “I’m not sure, I just know that it’s THEIR fault.”

t was repeated conversations like these that got me started asking American, Chinese and Taiwanese investors, analysts and officials a question that has been nagging at me for a while: What exactly are America and China fighting about?

the real answer is so much deeper and more complex than just the usual one-word response — “Taiwan” — or the usual three-word response — “autocracy versus democracy.”

Let me try to peel back the layers. The erosion in U.S.-China relations is a result of something old and obvious — a traditional great-power rivalry between an incumbent power (us) and a rising power (China) — but with lots of new twists

One of the twists, though, is that this standard-issue great-power rivalry is occurring between nations that have become as economically intertwined as the strands of a DNA molecule. As a result, neither China nor America has ever had a rival quite like the other.

in modern times, China, like America, has never had to deal with a true economic and military peer with which it was also totally intertwined through trade and investment.

Another new twist, and a reason it’s hard to define exactly what we’re fighting about, has a lot to do with how this elusive issue of trust and the absence of it have suddenly assumed much greater importance in international affairs.

This is a byproduct of our new technological ecosystem in which more and more devices and services that we both use and trade are driven by microchips and software, and connected through data centers in the cloud and high-speed internet

so many more things became “dual use.” That is, technologies that can easily be converted from civilian tools to military weapons, or vice versa.

no one country or company can own the whole supply chain. You need the best from everywhere, and that supply chain is so tightly intertwined that each company has to trust the others intimately.

when we install the ability to sense, digitize, connect, process, learn, share and act into more and more things — from your GPS-enabled phone to your car to your toaster to your favorite app — they all become dual use, either weapons or tools depending on who controls the software running them and who owns the data that they spin off.

As long as most of what China sold us was shallow goods, we did not care as much about its political system — doubly so because it seemed for a while as if China was slowly but steadily becoming more and more integrated with the world and slightly more open and transparent every year. So, it was both easy and convenient to set aside some of our worries about the dark sides of its political system.

when you want to sell us ‘deep goods’ — goods that are dual use and will go deep into our homes, bedrooms, industries, chatbots and urban infrastructure — we don’t have enough trust to buy them. So, we are going to ban Huawei and instead pay more to buy our 5G telecom systems from Scandinavian companies we do trust: Ericsson and Nokia.”

as we’ve seen in Ukraine, a smartphone can be used by Grandma to call the grandkids or to call a Ukrainian rocket-launching unit and give it the GPS coordinates of a Russian tank in her backyard.

So today, the country or countries that can make the fastest, most powerful and most energy efficient microchips can make the biggest A.I. computers and dominate in economics and military affairs.

As more and more products and services became digitized and electrified, the microchips that powered everything became the new oil. What crude oil was to powering 19th- and 20th-century economies, microchips are for powering 21st-century economies.

When you ask them what is the secret that enables TSMC to make 90 percent of the world’s most advanced logic chips — while China, which speaks the same language and shares the same recent cultural history, makes zero — their answer is simple: “trust.”

TSMC is a semiconductor foundry, meaning it takes the designs of the most advanced computer companies in the world — Apple, Qualcomm, Nvidia, AMD and others — and turns the designs into chips that perform different processing functions

TSMC makes two solemn oaths to its customers: TSMC will never compete against them by designing its own chips and it will never share the designs of one of its customers with another.

“Our business is to serve multiple competitive clients,” Kevin Zhang, senior vice president for business development at TSMC, explained to me. “We are committed not to compete with any of them, and internally our people who serve customer A will never leak their information to customer C.”

But by working with so many trusted partners, TSMC leverages the partners’ steadily more complex designs to make itself better — and the better it gets, the more advanced designs it can master for its customers. This not only requires incredibly tight collaboration between TSMC and its customers, but also between TSMC and its roughly 1,000 critical local and global suppliers.

As the physics of chip making gets more and more extreme, “the investment from customers is getting bigger and bigger, so they have to work with us more closely to make sure they harvest as much [computing power] as they can. They have to trust you.”

China also has a foundry, Semiconductor Manufacturing International Corporation, which is partly state-owned. But guess what? Because no global chip designers trust SMIC with their most advanced designs, it is at least a decade behind TSMC.

It’s for these reasons that the erosion in U.S.-China relations goes beyond our increasingly sharp disagreements over Taiwan. It is rooted in the fact that just when trust, and its absence, became much bigger factors in international affairs and commerce, China changed its trajectory. It made itself a less trusted partner right when the most important technology for the 21st century — semiconductors — required unprecedented degrees of trust to manufacture and more and more devices and services became deep and dual use.

when American trade officials said: “Hey, you need to live up to your W.T.O. commitments to restrict state-funding of industries,” China basically said: “Why should we live by your interpretation of the rules? We are now big enough to make our own interpretations. We’re too big; you’re too late.”

Combined with China’s failure to come clean on what it knew about the origins of Covid-19, its crackdown on democratic freedoms in Hong Kong and on the Uyghur Muslim minority in Xinjiang, its aggressive moves to lay claim to the South China Sea, its increasing saber rattling toward Taiwan, its cozying up to Vladimir Putin (despite his savaging of Ukraine), Xi’s moves toward making himself president for life, his kneecapping of China’s own tech entrepreneurs, his tighter restrictions on speech and the occasional abduction of a leading Chinese businessman — all of these added up to one very big thing: Whatever trust that China had built up with the West since the late 1970s evaporated at the exact moment in history when trust, and shared values, became more important than ever in a world of deep, dual-use products driven by software, connectivity and microchips.

it started to matter a lot more to Western nations generally and the United States in particular that this rising power — which we were now selling to or buying from all sorts of dual-use digital devices or apps — was authoritarian.

eijing, for its part, argues that as China became a stronger global competitor to America — in deep goods like Huawei 5G — the United States simply could not handle it and decided to use its control over advanced semiconductor manufacturing and other high-tech exports from America, as well as from our allies, to ensure China always remained in our rearview mirror

Beijing came up with a new strategy, called “dual circulation.” It said: We will use state-led investments to make everything we possibly can at home, to become independent of the world. And we will use our manufacturing prowess to make the world dependent on our exports.

Chinese officials also argue that a lot of American politicians — led by Trump but echoed by many in Congress — suddenly seemed to find it very convenient to put the blame for economic troubles in the U.S.’s middle class not on any educational deficiencies, or a poor work ethic, or automation or the 2008 looting by financial elites, and the crisis that followed, but on China’s exports to the United States.

As Beijing sees it, China not only became America’s go-to boogeyman, but in their frenzy to blame Beijing for everything, members of Congress started to more recklessly promote Taiwan’s independence.

Xi told President Biden at their summit in Bali in November, in essence: I will not be the president of China who loses Taiwan. If you force my hand, there will be war. You don’t understand how important this is to the Chinese people. You’re playing with fire.

at some level Chinese officials now understand that, as a result of their own aggressive actions in recent years on all the fronts I’ve listed, they have frightened both the world and their own innovators at precisely the wrong time.

I don’t buy the argument that we are destined for war. I believe that we are doomed to compete with each other, doomed to cooperate with each other and doomed to find some way to balance the two. Otherwise we are both going to have a very bad 21st century.

I have to say, though, Americans and Chinese remind me of Israelis and Palestinians in one respect: They are both expert at aggravating the other’s deepest insecurities.

China’s Communist Party is now convinced that America wants to bring it down, which some U.S. politicians are actually no longer shy about suggesting. So, Beijing is ready to crawl into bed with Putin, a war criminal, if that is what it takes to keep the Americans at bay.

Americans are now worried that Communist China, which got rich by taking advantage of a global market shaped by American rules, will use its newfound market power to unilaterally change those rules entirely to its advantage. So we’ve decided to focus our waning strength vis-à-vis Beijing on ensuring the Chinese will always be a decade behind us on microchips.

I don’t know what is sufficient to reverse these trends, but I think I know what is necessary.

If it is not the goal of U.S. foreign policy to topple the Communist regime in China, the United States needs to make that crystal clear, because I found a lot more people than ever before in Beijing think otherwise.

As for China, it can tell itself all it wants that it has not taken a U-turn in recent years. But no one is buying it. China will never realize its full potential — in a hyper-connected, digitized, deep, dual-use, semiconductor-powered world — unless it understands that establishing and maintaining trust is now the single most important competitive advantage any country or company can have. And Beijing is failing in that endeavor.

In his splendid biography of the great American statesman George Shultz, Philip Taubman quotes one of Shultz’s cardinal rules of diplomacy and life: “Trust is the coin of the realm.”

Two sources said that during the early weeks of the war they were permitted to kill 15 or 20 civilians during airstrikes on low-ranking militants. Attacks on such targets were typically carried out using unguided munitions known as “dumb bombs”, the sources said, destroying entire homes and killing all their occupants.

“You don’t want to waste expensive bombs on unimportant people – it’s very expensive for the country and there’s a shortage [of those bombs],” one intelligence officer said. Another said the principal question they were faced with was whether the “collateral damage” to civilians allowed for an attack.

“Because we usually carried out the attacks with dumb bombs, and that meant literally dropping the whole house on its occupants. But even if an attack is averted, you don’t care – you immediately move on to the next target. Because of the system, the targets never end. You have another 36,000 waiting.”

ccording to conflict experts, if Israel has been using dumb bombs to flatten the homes of thousands of Palestinians who were linked, with the assistance of AI, to militant groups in Gaza, that could help explain the shockingly high death toll in the war.

Details about the specific kinds of data used to train Lavender’s algorithm, or how the programme reached its conclusions, are not included in the accounts published by +972 or Local Call. However, the sources said that during the first few weeks of the war, Unit 8200 refined Lavender’s algorithm and tweaked its search parameters.

Responding to the publication of the testimonies in +972 and Local Call, the IDF said in a statement that its operations were carried out in accordance with the rules of proportionality under international law. It said dumb bombs are “standard weaponry” that are used by IDF pilots in a manner that ensures “a high level of precision”.

“The IDF does not use an artificial intelligence system that identifies terrorist operatives or tries to predict whether a person is a terrorist,” it added. “Information systems are merely tools for analysts in the target identification process.”

In earlier military operations conducted by the IDF, producing human targets was often a more labour-intensive process. Multiple sources who described target development in previous wars to the Guardian, said the decision to “incriminate” an individual, or identify them as a legitimate target, would be discussed and then signed off by a legal adviser.

n the weeks and months after 7 October, this model for approving strikes on human targets was dramatically accelerated, according to the sources. As the IDF’s bombardment of Gaza intensified, they said, commanders demanded a continuous pipeline of targets.

“We were constantly being pressured: ‘Bring us more targets.’ They really shouted at us,” said one intelligence officer. “We were told: now we have to fuck up Hamas, no matter what the cost. Whatever you can, you bomb.”

Lavender was developed by the Israel Defense Forces’ elite intelligence division, Unit 8200, which is comparable to the US’s National Security Agency or GCHQ in the UK.

After randomly sampling and cross-checking its predictions, the unit concluded Lavender had achieved a 90% accuracy rate, the sources said, leading the IDF to approve its sweeping use as a target recommendation tool.

Lavender created a database of tens of thousands of individuals who were marked as predominantly low-ranking members of Hamas’s military wing, they added. This was used alongside another AI-based decision support system, called the Gospel, which recommended buildings and structures as targets rather than individuals.

The accounts include first-hand testimony of how intelligence officers worked with Lavender and how the reach of its dragnet could be adjusted. “At its peak, the system managed to generate 37,000 people as potential human targets,” one of the sources said. “But the numbers changed all the time, because it depends on where you set the bar of what a Hamas operative is.”

broadly, and then the machine started bringing us all kinds of civil defence personnel, police officers, on whom it would be a shame to waste bombs. They help the Hamas government, but they don’t really endanger soldiers.”

Before the war, US and Israeli estimated membership of Hamas’s military wing at approximately 25-30,000 people.

there was a decision to treat Palestinian men linked to Hamas’s military wing as potential targets, regardless of their rank or importance.

According to +972 and Local Call, the IDF judged it permissible to kill more than 100 civilians in attacks on a top-ranking Hamas officials. “We had a calculation for how many [civilians could be killed] for the brigade commander, how many [civilians] for a battalion commander, and so on,” one source said.

Another source, who justified the use of Lavender to help identify low-ranking targets, said that “when it comes to a junior militant, you don’t want to invest manpower and time in it”. They said that in wartime there was insufficient time to carefully “incriminate every target”

So you’re willing to take the margin of error of using artificial intelligence, risking collateral damage and civilians dying, and risking attacking by mistake, and to live with it,” they added.

When it came to targeting low-ranking Hamas and PIJ suspects, they said, the preference was to attack when they were believed to be at home. “We were not interested in killing [Hamas] operatives only when they were in a military building or engaged in a military activity,” one said. “It’s much easier to bomb a family’s home. The system is built to look for them in these situations.”

Such a strategy risked higher numbers of civilian casualties, and the sources said the IDF imposed pre-authorised limits on the number of civilians it deemed acceptable to kill in a strike aimed at a single Hamas militant. The ratio was said to have changed over time, and varied according to the seniority of the target.

The IDF’s targeting processes in the most intensive phase of the bombardment were also relaxed, they said. “There was a completely permissive policy regarding the casualties of [bombing] operations,” one source said. “A policy so permissive that in my opinion it had an element of revenge.”

“There were regulations, but they were just very lenient,” another added. “We’ve killed people with collateral damage in the high double digits, if not low triple digits. These are things that haven’t happened before.” There appears to have been significant fluctuations in the figure that military commanders would tolerate at different stages of the war

One source said that the limit on permitted civilian casualties “went up and down” over time, and at one point was as low as five. During the first week of the conflict, the source said, permission was given to kill 15 non-combatants to take out junior militants in Gaza

at one stage earlier in the war they were authorised to kill up to “20 uninvolved civilians” for a single operative, regardless of their rank, military importance, or age.

“It’s not just that you can kill any person who is a Hamas soldier, which is clearly permitted and legitimate in terms of international law,” they said. “But they directly tell you: ‘You are allowed to kill them along with many civilians.’ … In practice, the proportionality criterion did not exist.”

Experts in international humanitarian law who spoke to the Guardian expressed alarm at accounts of the IDF accepting and pre-authorising collateral damage ratios as high as 20 civilians, particularly for lower-ranking militants. They said militaries must assess proportionality for each individual strike.

An international law expert at the US state department said they had “never remotely heard of a one to 15 ratio being deemed acceptable, especially for lower-level combatants. There’s a lot of leeway, but that strikes me as extreme”.

Sarah Harrison, a former lawyer at the US Department of Defense, now an analyst at Crisis Group, said: “While there may be certain occasions where 15 collateral civilian deaths could be proportionate, there are other times where it definitely wouldn’t be. You can’t just set a tolerable number for a category of targets and say that it’ll be lawfully proportionate in each case.”

Whatever the legal or moral justification for Israel’s bombing strategy, some of its intelligence officers appear now to be questioning the approach set by their commanders. “No one thought about what to do afterward, when the war is over, or how it will be possible to live in Gaza,” one said.

Another said that after the 7 October attacks by Hamas, the atmosphere in the IDF was “painful and vindictive”. “There was a dissonance: on the one hand, people here were frustrated that we were not attacking enough. On the other hand, you see at the end of the day that another thousand Gazans have died, most of them civilians.”
