Mr. Bogle has some hard news for investors. The basic appeal of index funds—their ability to deliver the market return without shifting an arm and leg to Wall Street’s army of helpers—will only become more important given the decade of depressed returns he sees ahead.

Don’t imagine a revisitation of the ’80s or ’90s, when stocks returned 18% a year and investors, after the industry’s rake-off, imagined they “had the greatest manager in the world” because they got 14%. Those planning on a comfy retirement or putting a kid through college will have to save more, work to keep costs low, and—above all—stick to the plan.

The mutual-fund industry is slowly liquidating itself—except for Vanguard. Mr. Bogle happily supplies the numbers: During the 12 months that ended May 31, “the fund industry took in $87 billion . . . of which $224 billion came into Vanguard.” In other words, “in the aggregate, our competitors experienced capital outflows of $137 billion.”

That said, Mr. Bogle finds today’s stock scene puzzling. Shares are highly priced in historical terms; earnings and economic growth he expects to disappoint for at least the next decade (he sees no point in trying to forecast further). And yet he advises investors to stay invested and weather the storm: “If we’re going to have lower returns, well, the worst thing you can do is reach for more yield. You just have to save more.”

He also knows the heartache of having just about everything he has saved tied up in volatile, sometimes irrational markets, especially now. “We’re in a difficult place,” he says. “We live in an extremely risky world—probably more risky than I can recall.”

Then why invest at all? Maybe it would be better to sell and stick the cash in a bank or a mattress. “I know of no better way to guarantee you’ll have nothing at the end of the trail,” he responds. “So we know we have to invest. And there’s no better way to invest than a diversified list of stocks and bonds at very low cost.”

Mr. Bogle’s own portfolio consists of 50% stocks and 50% bonds, the latter tilted toward short- and medium-term. Keep an eagle eye on costs, he says, in a world where pre-cost returns may be as low as 3% or 4%. Inattentive investors can expect to lose as much as 70% of their profits to “hidden” fund management costs in addition to the “expense ratios” touted in mutual-fund prospectuses. (These hidden costs include things like sales load, transaction costs, idle cash and inefficient taxes.)

Mr. Bogle relies on a forecasting model he published 25 years ago, which tells him that investors over the next decade, thanks largely to a reversion to the mean in valuations, will be lucky to clear 2% annually after costs. Yuck.

Investing, he says, always is “an act of trust—in the ability of civilization and the U.S. to continue to flourish; in the ability of corporations to continue, through efficiency and entrepreneurship and innovation, to provide substantial returns.” But nothing, not even American greatness, is guaranteed, he adds

what he calls the financial buccaneer type, an entrepreneur more interested in milking what’s left of the active-management-fee gravy train than in providing low-cost competition for Vanguard—which means Vanguard’s best days as guardian of America’s nest egg may still lie ahead.

the growth of indexing is obviously unwelcome writing on the wall for Wall Street professionals and Vanguard’s profit-making competitors like Fidelity, which have never been able to give heart and soul to low-churn indexing because indexing doesn’t generate large fees for executives and shareholders of management companies.

Russian President Vladimir Putin is demanding that the West rewrite the post-Cold War security arrangements for Europe and demonstrated that Russia has the military capability to impose its will despite Western objections and economic sanctions.

“We all thought we were looking at a Europe whole, free and at peace indefinitely,” said Michele Flournoy, who served as the Pentagon’s top policy official during the Obama administration. “We knew that Russia would conduct gray zone operations and that Putin would use his KGB playbook to create instability on his periphery. But a wholesale invasion of a sovereign country to reorient its government is a different moment.”

“And we’re seeing that while Beijing doesn’t really like Putin’s tactics, they’re willing to band together as authoritarian states against the Western democracies,” Ms. Flournoy added. “We are going to see more and more of that in the future.”

China’s Communist Party leadership also saw pro-democracy protest movements in former Soviet republics as U.S.-engineered plots that could ultimately be used against Beijing.

For much of the past decade, the U.S. security establishment began taking note of what the Pentagon in 2015 called the “re-emergence of great power competition” and shifted from its emphasis of counterterrorism operations in the Middle East and Southwest Asia.

Defense Secretary Lloyd Austin has repeatedly cast China as the “pacing challenge” while Russia was seen as the lesser longer-term danger.

Even with annual defense budgets that soared over $700 billion, coping with an urgent Russian-generated crisis while preparing for a Chinese threat whose peak is still years away presents an enormous challenge for the Pentagon.

”The United States is particularly at risk of being overwhelmed should its military be forced to fight on two or more fronts simultaneously,” said a Congressionally mandated study of the Pentagon’s strategy that was issued in 2018

The era of nuclear reductions may come to an end as the U.S. military establishment argues for a large enough nuclear arsenal to deter both Russia’s formidable nuclear weaponry and China’s rapidly growing nuclear forces, which aren’t limited by any arms-control agreement.

“The United States is going to have to get used again to operating in multiple theaters simultaneously—not just militarily, but in terms of psychology and foreign-policy making,”

Already, debates are emerging among U.S. defense experts on whether the Pentagon should give equal weight to the twin challenges from Beijing and Moscow or focus more on the Pacific.

Should the West impose crippling sanctions on Russian banks and major companies, Moscow is likely to become more reliant on Beijing, which has issued a digital currency and is building a payments system separate from the West’s.

“It is already ending the amnesia about the importance of energy security,” said Daniel Yergin, vice chairman of research firm IHS Markit. “It means a new emphasis on diversification of energy sources for Europe and a new look at U.S. domestic and international energy policies.”

Advocates of using energy as a geopolitical tool say Washington should promote investment in U.S. oil and natural gas and approve new LNG export terminals and pipelines in the United States.

The 1997 NATO-Russia Founding Act precludes the alliance from permanently stationing additional substantial combat forces on the territory of its new Eastern and Central European members, but could now be repealed.

A recent poll by the European Council on Foreign Relations noted most Europeans see the Ukraine crisis as a broader threat to Europe. Some current and former officials, however, worry that the alliance’s solidarity could fray in the years ahead as it debates the need for greater military spending and wrestles whether its military ties with Georgia might stir new confrontations with Moscow.

the Alphen Group by former officials and other experts urges that European members of the alliance and Canada provide for 50% of NATO’s minimum military requirements by 2030 so the U.S. can focus more on deterring China.

“Everybody’s unified right now and outraged about what the Russians are doing,” said Alexander Vershbow, a former U.S. ambassador to NATO who also served as the alliance’s deputy secretary-general from 2012 to 2016. “But when we get down to making longer-term commitments to strengthen NATO’s defense posture and potentially revisit nuclear issues, it could become very divisive.”

he raged at the alliance’s eastward expansion. Later, he decried a fictitious “genocide” that he says the West is sponsoring in Ukraine. Mr Putin can’t tell his people that his army is fighting against their Ukrainian brothers and sisters who gained freedom.

Even though Russia has set out to build a fortress economy, the country is still connected to the world and, as the initial 45% fall in Russia’s stockmarket suggests, it will suffer.

Russia is Europe’s main supplier of gas. It exports metals like nickel and palladium and along with Ukraine it exports wheat. All of that will present problems at a time when the world economy is struggling with inflation and supply-chain glitches.

Some will say that it is too risky to challenge Mr Putin in these ways—because he has lost touch with reality, or because he will escalate, miscalculate or hug China

After 22 years at the top, even a dictator with an overdeveloped sense of his own destiny has a nose for survival and the ebb and flow of power.

Even China should see that a man who rampages across frontiers is a threat to the stability it seeks.

They will also signal to Mr Putin that the further he pushes in Ukraine, the more likely he is to end up strengthening NATO’s presence on its border—the very opposite of what he intends.

Upon his arrival at Rzeszów-Jasionka Airport, Biden will be greeted by Polish President Andrzej Duda and receive a briefing on the humanitarian response to the war. He'll meet with service members from the 82nd Airborne Division in Rzeszów before traveling to Warsaw in the evening.On Saturday, the White House says Biden will hold a bilateral meeting with Duda to discuss how the US and allies are responding to the refugee crisis that has ensued as a result of the war. He'll also deliver remarks before returning to Washington.Biden's travel to Poland comes after meetings on Thursday in Brussels, where he attended a slate of emergency summits, announced new actions -- such as sanctions against hundreds of members of Russia's parliament and a commitment to admit 100,000 refugees fleeing Ukraine -- and conferred with global leaders on how the world will respond if Russia deploys a chemical, biological or nuclear weapon.

Poland, which borders Ukraine to the west, has registered more than 2 million Ukrainian refugees crossing into the country. However, the number of refugees staying in Poland is lower, with many continuing on in their journey to other countries.Earlier this month during Vice President Kamala Harris' trip to Poland, Duda personally asked the vice president to speed up and simplify the procedures allowing Ukrainians with family in the US to come to the country. He also warned Harris that his country's resources were being badly strained by the influx of refugees, even as Poland welcomes them with open arms.The White House says that since February 24, the US has provided more than $123 million to assist countries neighboring Ukraine and the European Union to address the refugee influx, including $48 million in Poland.

Biden brought up that he has visited war zones, saying he understood the plight of refugees."I've been in refugee camps. I've been in war zones for the last 15 years. And it's -- it's devastating," he said.Biden also said the refugee influx is "not something that Poland or Romania or Germany should carry on their own."

The Poland trip also comes two weeks after the US rejected Poland's proposals to facilitate the transfer its MiG-29 fighter jets to Ukraine. The US rejected Poland's proposals over fears that the US and NATO could be perceived as taking an escalatory step, further fomenting conflict between the alliance and Russia -- which adamantly opposes Ukraine's ambitions to join the NATO alliance.Ukrainian President Volodymyr Zelensky has repeatedly requested more aircraft for the invasion, making another appeal to NATO leaders on Thursday.

There is no dispute now that Mr Putin wants to defend Russia’s sphere of influence. Right at the start of his speech on February 24th, as his forces invaded Ukraine, he criticised the “expansion of the NATO bloc to the east, bringing its military infrastructure closer to Russian borders”

However, for Professor Mearsheimer to reduce the causes of Russia's invasion to the Bucharest declaration is simplistic and wrong.

For a start, there were some obvious frustrations, fears and mistakes.

The continuing American strategic partnership with Ukraine, which Professor Mearsheimer mentions, may indeed have played a part

Ukrainian defiance in response to Russia’s huge military exercise on its border last year would have been hard for Mr Putin to tolerate. A successful and democratic Ukraine undermines the Russian leader’s own authoritarianism at home.

there was a faulty understanding of the situation on the ground: both America in Iraq and Russia in Ukraine have launched wars on terrible “intelligence”.

there are three other factors that help to explain the current crisis in Ukraine.

the break-up of empires is often messy and traumatic. Often foreign military intervention of some kind follows. The end of European colonial empires, and the collapse of the Soviet and Yugoslav empires in the 1990s, forced new or re-constituted states to make fateful decisions. Is citizenship based on ethnicity or simply residence? Should kin living outside the state have a right to citizenship? What frontiers does the state have? What friends and allies? What constitution? What language

Both Georgia and Ukraine faced many if not all of these quandaries in the 1990s—and faced them long before the question of NATO membership arose.

Second, the existence of nuclear weapons outside of Russia necessitated a degree of Western involvement in security matters. An array of nuclear weapons remained in Ukraine

The breakdown of the Budapest Memorandum left Ukraine in an awkward situation. It was unable to trust Russia’s word, but also had reason to doubt Western security guarantees. The idea of full-blooded membership of NATO appeared increasingly attractive but not necessarily more attainable.

The third factor is colour revolutions—the popular revolutions that occurred in many countries in the former Soviet Union in recent decades. They must have reminded Mr Putin of the movements in eastern Europe in 1989 that precipitated the collapse of one communist regime after another.

It suits Mr Putin to treat civil resistance movements as parts of a grand international conspiracy. I have been studying such movements for more than 50 years. In that time all kinds of accusations have been made that such movements are the pawns of outside forces. There is little evidence to support such theories.

Throughout his analysis Professor Mearsheimer pays remarkably little attention to the ideals and political desires of people in countries that have experienced “people power” revolutions.

These factors suggest that the 2008 proposal to expand NATO to include Georgia and Ukraine is just one among many developments that have made the current crisis so acute

It is arguable, indeed likely, that the NATO expansion proposal made matters worse, as may some other Western actions, but to assert that “the West is principally responsible for the Ukrainian crisis” goes too far.

Telegram videos and more. Ukrainian entrepreneurs are even hijacking their own apps to let Russians know what’s going on. While such efforts have mixed success, they demonstrate the ingenuity needed to win the information battle that’s as old as war itself.

Meanwhile, an organization called Squad303 built an online tool that lets people automatically send Russians texts, WhatsApp messages and emails. Some of the most effective strategies rely on old-school technologies. The use of virtual private networks, or VPNs, has skyrocketed in Russia since the war began. That may explain why the country’s telecom regulator has forced Google to delist thousands of URLs linked to VPN sites.

For Paulius Senūta, an advertising executive in Lithuania, the weapon of choice is the telephone. He recently launched “CallRussia,” a website that enables Russian speakers to cold-call random Russians based on a directory of 40 million phone numbers. Visitors to the site get a phone number along with a basic script developed by psychologists that advises callers to share their Russian connections and volunteer status before encouraging targets to hear what’s really going on. Suggested lines include “The only thing (Putin) seems to fear is information,” which then lets callers stress the need to put it “in the hands of Russians who know the truth and stand up to stop this war.” In its first eight days, Senūta says users from eastern Europe and elsewhere around the world placed nearly 100,000 calls to strangers in Russia.

“One thing is to call them and the other thing is how to talk with them,” says Senūta. As with any telemarketing call, the response from those on the receiving end has been mixed. While some have been receptive, others are angry at the interruption or suspicious that it’s a trick. “How do you speak to someone who has been in a different media environment?”

Terms like “war,” “invasion,” or “aggression” have been banned from coverage, punishable by fines of up to five million rubles (now roughly $52,000) or 15 years in prison. Says Kozlovsky: “It’s getting worse and worse.”

Arnold Schwarzenegger uploaded a lengthy video message to Russians via Telegram that included both Russian and English subtitles.) However, that it doesn’t mean it hurts to also try new things.

The question is whether Russians realize they’re being fed on a media diet of state-sponsored lies and criminalization of the truth. Dittmer believes many Russians are eager to know what’s really going on. So far, RSF’s “Truth Wins” campaign has been viewed more than 150,000 times in Russia. (Previous efforts by DDB and RSF in various countries have included embedding censored news in a virtual library within Minecraft and a playlist on Spotify.)

Censorship also cuts both ways. While Russian authorities have banned Facebook and Instagram as “extremist,” Western news outlets have in turn cut ties with state-controlled outlets because of Putin’s disinformation campaign. While pulling products and partnerships out of Russia may send a powerful message to the Kremlin, such isolation also risks leaving a bubble of disinformation intact. Luckily, “it’s pretty much impossible to censor effectively,” says RSF’s Dittmer, pointing to further efforts to use blockchain and gaming technology to spread news. “We can play the cat and mouse game with the internet censors in a slightly more sophisticated way.”

Among the investigators’ other findings, they also highlighted how people had been reportedly detained for expressing “views about the elections, or support for candidate

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Here’s what would actually need to be done:

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

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

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

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

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

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

The Tesla Inc. CEO tweeted in February that OpenAI had been founded as an open-source nonprofit “to serve as a counterweight to Google, but now it has become a closed source, maximum-profit company effectively controlled by Microsoft. Not what I intended at all.”

Backers say his brand of social-minded capitalism makes him the ideal person to lead OpenAI. Others, including some who’ve worked for him, say he’s too commercially minded and immersed in Silicon Valley thinking to lead a technological revolution that is already reshaping business and social life. 

In the long run, he said, he wants to set up a global governance structure that would oversee decisions about the future of AI and gradually reduce the power OpenAI’s executive team has over its technology. 

OpenAI researchers soon concluded that the most promising path to achieve artificial general intelligence rested in large language models, or computer programs that mimic the way humans read and write. Such models were trained on large volumes of text and required a massive amount of computing power that OpenAI wasn’t equipped to fund as a nonprofit, according to Mr. Altman. 

In its founding charter, OpenAI pledged to abandon its research efforts if another project came close to building AGI before it did. The goal, the company said, was to avoid a race toward building dangerous AI systems fueled by competition and instead prioritize the safety of humanity.

While running Y Combinator, Mr. Altman began to nurse a growing fear that large research labs like DeepMind, purchased by Google in 2014, were creating potentially dangerous AI technologies outside the public eye. Mr. Musk has voiced similar concerns of a dystopian world controlled by powerful AI machines. 

Messrs. Altman and Musk decided it was time to start their own lab. Both were part of a group that pledged $1 billion to the nonprofit, OpenAI Inc. 

Mr. Altman said he doesn’t necessarily need to be first to develop artificial general intelligence, a world long imagined by researchers and science-fiction writers where software isn’t just good at one specific task like generating text or images but can understand and learn as well or better than a human can. He instead said OpenAI’s ultimate mission is to build AGI, as it’s called, safely.

“We didn’t have a visceral sense of just how expensive this project was going to be,” he said. “We still don’t.”

Tensions also grew with Mr. Musk, who became frustrated with the slow progress and pushed for more control over the organization, people familiar with the matter said. 

OpenAI executives ended up reviving an unusual idea that had been floated earlier in the company’s history: creating a for-profit arm, OpenAI LP, that would report to the nonprofit parent. 

Reid Hoffman, a LinkedIn co-founder who advised OpenAI at the time and later served on the board, said the idea was to attract investors eager to make money from the commercial release of some OpenAI technology, accelerating OpenAI’s progress

“You want to be there first and you want to be setting the norms,” he said. “That’s part of the reason why speed is a moral and ethical thing here.”

The decision further alienated Mr. Musk, the people familiar with the matter said. He parted ways with OpenAI in February 2018. 

Mr. Musk announced his departure in a company all-hands, former employees who attended the meeting said. Mr. Musk explained that he thought he had a better chance at creating artificial general intelligence through Tesla, where he had access to greater resources, they said.

OpenAI said that it received about $130 million in contributions from the initial $1 billion pledge, but that further donations were no longer needed after the for-profit’s creation. Mr. Musk has tweeted that he donated around $100 million to OpenAI. 

Mr. Musk’s departure marked a turning point. Later that year, OpenAI leaders told employees that Mr. Altman was set to lead the company. He formally became CEO and helped complete the creation of the for-profit subsidiary in early 2019.

A young researcher questioned whether Mr. Musk had thought through the safety implications, the former employees said. Mr. Musk grew visibly frustrated and called the intern a “jackass,” leaving employees stunned, they said. It was the last time many of them would see Mr. Musk in person.  

In the meantime, Mr. Altman began hunting for investors. His break came at Allen & Co.’s annual conference in Sun Valley, Idaho in the summer of 2018, where he bumped into Satya Nadella, the Microsoft CEO, on a stairwell and pitched him on OpenAI. Mr. Nadella said he was intrigued. The conversations picked up that winter.

“I remember coming back to the team after and I was like, this is the only partner,” Mr. Altman said. “They get the safety stuff, they get artificial general intelligence. They have the capital, they have the ability to run the compute.”   

Mr. Altman disagreed. “The unusual thing about Microsoft as a partner is that it let us keep all the tenets that we think are important to our mission,” he said, including profit caps and the commitment to assist another project if it got to AGI first. 

Some employees still saw the deal as a Faustian bargain. 

OpenAI’s lead safety researcher, Dario Amodei, and his lieutenants feared the deal would allow Microsoft to sell products using powerful OpenAI technology before it was put through enough safety testing,

They felt that OpenAI’s technology was far from ready for a large release—let alone with one of the world’s largest software companies—worrying it could malfunction or be misused for harm in ways they couldn’t predict.  

Mr. Amodei also worried the deal would tether OpenAI’s ship to just one company—Microsoft—making it more difficult for OpenAI to stay true to its founding charter’s commitment to assist another project if it got to AGI first, the former employees said.

Microsoft initially invested $1 billion in OpenAI. While the deal gave OpenAI its needed money, it came with a hitch: exclusivity. OpenAI agreed to only use Microsoft’s giant computer servers, via its Azure cloud service, to train its AI models, and to give the tech giant the sole right to license OpenAI’s technology for future products.

In a recent investment deck, Anthropic said it was “committed to large-scale commercialization” to achieve the creation of safe AGI, and that it “fully committed” to a commercial approach in September. The company was founded as an AI safety and research company and said at the time that it might look to create commercial value from its products. 

Mr. Altman “has presided over a 180-degree pivot that seems to me to be only giving lip service to concern for humanity,” he said. 

“The deal completely undermines those tenets to which they secured nonprofit status,” said Gary Marcus, an emeritus professor of psychology and neural science at New York University who co-founded a machine-learning company

The cash turbocharged OpenAI’s progress, giving researchers access to the computing power needed to improve large language models, which were trained on billions of pages of publicly available text. OpenAI soon developed a more powerful language model called GPT-3 and then sold developers access to the technology in June 2020 through packaged lines of code known as application program interfaces, or APIs. 

Mr. Altman and Mr. Amodei clashed again over the release of the API, former employees said. Mr. Amodei wanted a more limited and staged release of the product to help reduce publicity and allow the safety team to conduct more testing on a smaller group of users, former employees said. 

Mr. Amodei left the company a few months later along with several others to found a rival AI lab called Anthropic. “They had a different opinion about how to best get to safe AGI than we did,” Mr. Altman said.

Anthropic has since received more than $300 million from Google this year and released its own AI chatbot called Claude in March, which is also available to developers through an API. 

Mr. Altman shared the contract with employees as it was being negotiated, hosting all-hands and office hours to allay concerns that the partnership contradicted OpenAI’s initial pledge to develop artificial intelligence outside the corporate world, the former employees said. 

In the three years after the initial deal, Microsoft invested a total of $3 billion in OpenAI, according to investor documents. 

More than one million users signed up for ChatGPT within five days of its November release, a speed that surprised even Mr. Altman. It followed the company’s introduction of DALL-E 2, which can generate sophisticated images from text prompts.

By February, it had reached 100 million users, according to analysts at UBS, the fastest pace by a consumer app in history to reach that mark.

n’s close associates praise his ability to balance OpenAI’s priorities. No one better navigates between the “Scylla of misplaced idealism” and the “Charybdis of myopic ambition,” Mr. Thiel said. 

Mr. Altman said he delayed the release of the latest version of its model, GPT-4, from last year to March to run additional safety tests. Users had reported some disturbing experiences with the model, integrated into Bing, where the software hallucinated—meaning it made up answers to questions it didn’t know. It issued ominous warnings and made threats. 

“The way to get it right is to have people engage with it, explore these systems, study them, to learn how to make them safe,” Mr. Altman said.

After Microsoft’s initial investment is paid back, it would capture 49% of OpenAI’s profits until the profit cap, up from 21% under prior arrangements, the documents show. OpenAI Inc., the nonprofit parent, would get the rest.

He has put almost all his liquid wealth in recent years in two companies. He has put $375 million into Helion Energy, which is seeking to create carbon-free energy from nuclear fusion and is close to creating “legitimate net-gain energy in a real demo,” Mr. Altman said.

He has also put $180 million into Retro, which aims to add 10 years to the human lifespan through “cellular reprogramming, plasma-inspired therapeutics and autophagy,” or the reuse of old and damaged cell parts, according to the company. 

He noted how much easier these problems are, morally, than AI. “If you’re making nuclear fusion, it’s all upside. It’s just good,” he said. “If you’re making AI, it is potentially very good, potentially very terrible.” 

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

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

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

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

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

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

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

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

And yet, when people act as if Mr. Altman has nearly realized his long-held vision, he pushes back.

This past week, more than a thousand A.I. experts and tech leaders called on OpenAI and other companies to pause their work on systems like ChatGPT, saying they present “profound risks to society and humanity.”

As people realize that this technology is also a way of spreading falsehoods or even persuading people to do things they should not do, some critics are accusing Mr. Altman of reckless behavior.

“The hype over these systems — even if everything we hope for is right long term — is totally out of control for the short term,” he told me on a recent afternoon. There is time, he said, to better understand how these systems will ultimately change the world.

Many industry leaders, A.I. researchers and pundits see ChatGPT as a fundamental technological shift, as significant as the creation of the web browser or the iPhone. But few can agree on the future of this technology.

Some believe it will deliver a utopia where everyone has all the time and money ever needed. Others believe it could destroy humanity. Still others spend much of their time arguing that the technology is never as powerful as everyone says it is, insisting that neither nirvana nor doomsday is as close as it might seem.

he is often criticized from all directions. But those closest to him believe this is as it should be. “If you’re equally upsetting both extreme sides, then you’re doing something right,” said OpenAI’s president, Greg Brockman.

To spend time with Mr. Altman is to understand that Silicon Valley will push this technology forward even though it is not quite sure what the implications will be

in 2019, he paraphrased Robert Oppenheimer, the leader of the Manhattan Project, who believed the atomic bomb was an inevitability of scientific progress. “Technology happens because it is possible,” he said

His life has been a fairly steady climb toward greater prosperity and wealth, driven by an effective set of personal skills — not to mention some luck. It makes sense that he believes that the good thing will happen rather than the bad.

He said his company was building technology that would “solve some of our most pressing problems, really increase the standard of life and also figure out much better uses for human will and creativity.”

He was not exactly sure what problems it will solve, but he argued that ChatGPT showed the first signs of what is possible. Then, with his next breath, he worried that the same technology could cause serious harm if it wound up in the hands of some authoritarian government.

Kelly Sims, a partner with the venture capital firm Thrive Capital who worked with Mr. Altman as a board adviser to OpenAI, said it was like he was constantly arguing with himself.

“In a single conversation,” she said, “he is both sides of the debate club.”

He takes pride in recognizing when a technology is about to reach exponential growth — and then riding that curve into the future.

he is also the product of a strange, sprawling online community that began to worry, around the same time Mr. Altman came to the Valley, that artificial intelligence would one day destroy the world. Called rationalists or effective altruists, members of this movement were instrumental in the creation of OpenAI.

Does it make sense to ride that curve if it could end in diaster? Mr. Altman is certainly determined to see how it all plays out.

“Why is he working on something that won’t make him richer? One answer is that lots of people do that once they have enough money, which Sam probably does. The other is that he likes power.”

“He has a natural ability to talk people into things,” Mr. Graham said. “If it isn’t inborn, it was at least fully developed before he was 20. I first met Sam when he was 19, and I remember thinking at the time: ‘So this is what Bill Gates must have been like.

poker taught Mr. Altman how to read people and evaluate risk.

It showed him “how to notice patterns in people over time, how to make decisions with very imperfect information, how to decide when it was worth pain, in a sense, to get more information,” he told me while strolling across his ranch in Napa. “It’s a great game.”

He believed, according to his younger brother Max, that he was one of the few people who could meaningfully change the world through A.I. research, as opposed to the many people who could do so through politics.

In 2019, just as OpenAI’s research was taking off, Mr. Altman grabbed the reins, stepping down as president of Y Combinator to concentrate on a company with fewer than 100 employees that was unsure how it would pay its bills.

Within a year, he had transformed OpenAI into a nonprofit with a for-profit arm. That way he could pursue the money it would need to build a machine that could do anything the human brain could do.

Mr. Brockman, OpenAI’s president, said Mr. Altman’s talent lies in understanding what people want. “He really tries to find the thing that matters most to a person — and then figure out how to give it to them,” Mr. Brockman told me. “That is the algorithm he uses over and over.”

Mr. Yudkowsky and his writings played key roles in the creation of both OpenAI and DeepMind, another lab intent on building artificial general intelligence.

“These are people who have left an indelible mark on the fabric of the tech industry and maybe the fabric of the world,” he said. “I think Sam is going to be one of those people.”

The trouble is, unlike the days when Apple, Microsoft and Meta were getting started, people are well aware of how technology can transform the world — and how dangerous it can be.

Mr. Scott of Microsoft believes that Mr. Altman will ultimately be discussed in the same breath as Steve Jobs, Bill Gates and Mark Zuckerberg.

The woman was the Canadian singer Grimes, Mr. Musk’s former partner, and the hat guy was Eliezer Yudkowsky, a self-described A.I. researcher who believes, perhaps more than anyone, that artificial intelligence could one day destroy humanity.

The selfie — snapped by Mr. Altman at a party his company was hosting — shows how close he is to this way of thinking. But he has his own views on the dangers of artificial intelligence.

In March, Mr. Altman tweeted out a selfie, bathed by a pale orange flash, that showed him smiling between a blond woman giving a peace sign and a bearded guy wearing a fedora.

He also helped spawn the vast online community of rationalists and effective altruists who are convinced that A.I. is an existential risk. This surprisingly influential group is represented by researchers inside many of the top A.I. labs, including OpenAI.

They don’t see this as hypocrisy: Many of them believe that because they understand the dangers clearer than anyone else, they are in the best position to build this technology.

Mr. Altman believes that effective altruists have played an important role in the rise of artificial intelligence, alerting the industry to the dangers. He also believes they exaggerate these dangers.

As OpenAI developed ChatGPT, many others, including Google and Meta, were building similar technology. But it was Mr. Altman and OpenAI that chose to share the technology with the world.

Many in the field have criticized the decision, arguing that this set off a race to release technology that gets things wrong, makes things up and could soon be used to rapidly spread disinformation.

Mr. Altman argues that rather than developing and testing the technology entirely behind closed doors before releasing it in full, it is safer to gradually share it so everyone can better understand risks and how to handle them.

He told me that it would be a “very slow takeoff.”

When I asked Mr. Altman if a machine that could do anything the human brain could do would eventually drive the price of human labor to zero, he demurred. He said he could not imagine a world where human intelligence was useless.

If he’s wrong, he thinks he can make it up to humanity.

His grand idea is that OpenAI will capture much of the world’s wealth through the creation of A.G.I. and then redistribute this wealth to the people. In Napa, as we sat chatting beside the lake at the heart of his ranch, he tossed out several figures — $100 billion, $1 trillion, $100 trillion.

If A.G.I. does create all that wealth, he is not sure how the company will redistribute it. Money could mean something very different in this new world.

But as he once told me: “I feel like the A.G.I. can help with that.”

The spirit of Barabbas — the desire to seize or retain power, through violence if necessary — has been at war with the spirit of Christ ever since. Two millenniums of church history demonstrate a terrible truth: There was nothing uniquely evil about that ancient crowd. Instead it held up a mirror to our own nature, one that is all too eager to wield the sword, to believe that our own power is a prerequisite to justice.

Easter weekend contains more than one example of the spirit of Barabbas. When Christ was arrested, the Apostle Peter — a man who had been by his side for much of his ministry — still could not see the truth. He drew his sword, struck the high priest’s servant, and cut off his ear.

Though he was in the midst of an unjust arrest that would prove prelude to an unjust execution, Christ rebuked Peter, saying, “Put your sword back in its place, because all who take up the sword will perish by the sword.” As he reminded Peter, Jesus had the power to call on “legions of angels” to stop the arrest, but he chose not to. His purpose was to go to the cross, and as Jesus told us, that’s our purpose as well.

There is a difference between the quest for power and the quest for justice. Believers are required to “act justly.” We should not stand idly by in the face of exploitation or oppression. We do not retreat from the public square. But Christian engagement must be distinctive. It cannot emulate the world’s methods or morality.

the example of Jesus dominated the minds of civil rights leaders. “We discussed and debated the teachings of the great teacher, and we would ask questions about what would Jesus do,” said Lewis. “In preparing for the sit-ins, we felt that the message was one of love — the message of love in action: Don’t hate. If someone hits you, don’t strike back. Just turn the other side. Be prepared to forgive.”

The spirit of Barabbas was alive and well in the men who trained their fire hoses on peaceful protesters, who loosed dogs on the Black children of Birmingham. They weren’t trying to seize power, but they were trying to maintain it, through violent, lawless means. Their will to power collided with the quest for justice. It is only through God’s grace and the unimaginable courage and persistence of peaceful protesters that justice prevailed, and Jim Crow laws were overturned.

The spirit of Barabbas tempts Christians even today. You see it when armed Christians idolize their guns, when angry Christians threaten and attempt to intimidate their political opponents, when fearful Christians adopt the tactics and ethos of Trumpism to preserve their power. The spirit of Barabbas most clearly captured the mob on Jan. 6, when praying Americans participated in an insurrection based on a lie.

Christ did not reject earthly rule so that his flawed followers could seize the world’s thrones. His ethos was clear: “You know that the rulers of the gentiles lord it over them, and those in high positions act as tyrants over them. It must not be like that among you. On the contrary, whoever wants to become great among you must be your servant.”

Mr. Khamenei’s ruling philosophy has been shaped and reinforced by three notable authoritarian collapses: The 1979 fall of Iran’s monarchy, the 1991 dissolution of the Soviet Union and the Arab uprisings of 2011. His takeaway from each of these events has been to never compromise under pressure and never compromise on principles.

The Iranian regime’s repressive capacity — at least on paper — remains formidable. Ayatollah Khamenei is commander in chief of 190,000 armed members of the Islamic Revolutionary Guard Corps, who oversee tens of thousands of Basij militants tasked with instilling public fear and morality.

Iran’s nonideological conscription army, whose active forces are an estimated 350,000, is unlikely to take part in mass repression

Until now, the political and financial interests of Ayatollah Khamenei and the Revolutionary Guards have been intertwined. But persistent protests and chants of “Death to Khamenei” might change that

The sociologist Charles Kurzman wrote in his seminal book, “The Unthinkable Revolution in Iran,” that the paradox of revolutionary movements is that they are not viable until they attract a critical mass of supporters but that to attract a critical mass of supporters, they must be perceived as viable.

If the organizing principle that united Iran’s disparate opposition forces in 1979 was anti-imperialism, the organizing principles of today’s socioeconomically and ethnically diverse movement are pluralism and patriotism.

The faces of this movement are not ideologues or intellectuals but athletes, musicians and ordinary people, especially women and ethnic minorities, who have shown uncommon courage. Their slogans are patriotic and progressive — “We will not leave Iran, we will reclaim Iran,” and “Women, life, freedom.”

The demands of the current movement are brilliantly distilled in Shervin Hajipour’s song “Baraye,” or “For,” which has become the anthem of the protests and articulates a “yearning for a normal life” rather than the “forced paradise” of a religious police state.

Abbas Amanat, a historian of Iran, observed that one of the keys to Iran’s civilizational longevity, which dates to the Persian Empire of 2,500 years ago, is the power of its culture to co-opt its military invaders. “For nearly two millenniums, Persian political culture and, in a broader sense, a repository of Persian civilizational tools successfully managed to convert Turkic, Arab and Mongolian conquerors,” he told me. “Persian language, myth, historical memories and timekeeping endured. Iranians persuaded invaders to appreciate a Persian high culture of poetry, food, painting, wine, music, festivals and etiquette.”

When Ayatollah Khomeini acquired power in 1979, he led a cultural revolution that sought to replace Iranian patriotism with a purely Islamic identity. Ayatollah Khamenei continues that tradition, but he is one of the few remaining true believers. While the Islamic Republic sought to subdue Iranian culture, it is Iranian culture and patriotism that are threatening to undo the Islamic Republic.

Four decades of the Islamic Republic’s hard power will ultimately be defeated by two millenniums of Iranian cultural soft power. The question is no longer about whether this will happen but when.

Ukrainians are aware of their new superiority in conventional arms and want to press their advantage to the maximum.

Nuclear escalation seems to be a joker that Putin wants to keep in play. What will he do if more retreat and humiliation come his way? The discussion tends to go in circles, focusing on Putin’s megalomania and his habit of surprising people. All of which leaves a room for a disconcerting level of uncertainty. Clearly, Putin intends to keep it that way. So far, the Russian ruler links the preservation of Russia’s “sovereignty” not to successful diplomacy but to nuclear deterrence and, if need be, brinkmanship.

In Moscow, the environment is quite the opposite. Putin, his propagandists and top military no longer say “nuclear war must not be waged”. Instead, they seem to be stoking fears of nuclear conflict. The story of Khrushchev’s gamble and retreat is rarely discussed, and its details have not been digested by the current cohort of decision-makers. Many crucial files still remain secret and forgotten, gathering dust in archives

The Ukrainian offensive, backed by US weapons and intelligence, has become part of a precarious web of international security. Will the Ukrainians push to regain all their lost territory or stop at the border of Crimea? Will they start shelling Sevastopol with US-provided missile launchers? If they do, the pressure on Putin to escalate would increase enormously

Imagine what Kennedy would have done in October 1962 had the Cubans been given the opportunity to shell cities in Florida. If the Kremlin has no more conventional ways to escalate, the temptation to use a tactical nuclear device will grow.

As his delusional gamble in Ukraine produces one military retreat after another, Putin has to find an exit. We simply have no means of knowing what kind of an exit he will choose, and whether it will come with a bang.

Karahan Tepe, and its penis chamber, and everything that inexplicably surrounds the chamber – shrines, cells, altars, megaliths, audience halls et al – is vastly older than anything comparable, and plumbs quite unimaginable depths of time, back before agriculture, probably back before normal pottery, right back to a time when we once thought human ‘civilisation’ was simply impossible.

After all, hunter gatherers – cavemen with flint arrowheads – without regular supplies of grain, without the regular meat and milk of domesticated animals, do not build temple-towns with water systems.

Taken together with its age, complexity, sophistication, and its deep, resonant mysteriousness, and its many sister sites now being unearthed across the Harran Plains – collectively known as the Tas Tepeler, or the ‘stone hills’ – these carved, ochre-red rocks, so silent, brooding, and watchful in the hard whirring breezes of the semi-desert, constitute what might just be the greatest archaeological revelation in the history of humankind.

The solitary Kurdish man, on that summer’s day in 1994, had made an irreversibly profound discovery – which would eventually lead to the penis pillars of Karahan Tepe, and an archaeological anomaly which challenges, time and again, everything we know of human prehistory.

in late 1994 the German archaeologist Klaus Schmidt came to the site of Gobekli Tepe to begin his slow, diligent excavations of its multiple, peculiar, enormous T-stones, which are generally arranged in circles – like the standing stones of Avebury or Stonehenge. Unlike European standing stones, however, the older Turkish megaliths are often intricately carved: with images of local fauna. Sometimes the stones depict cranes, boars, or wildfowl: creatures of the hunt. There are also plenty of leopards, foxes, and vultures. Occasionally these animals are depicted next to human heads.

The obsession with the penis is obvious – more so, now we have the benefit of hindsight provided by Karahan Tepe and the other sites. Very few representations of women have emerged from the Tas Tepeler so far; there is one obscene caricature of a woman perhaps giving birth. Whatever inspired these temple-towns it was a not a benign matriarchal culture. Quite the opposite, maybe.

Urfa man now has a silent hall of his own in one of Turkey’s greatest archaeological galleries. More importantly, we can now see that Urfa man has the same body stance of the T-shaped man-pillars at Gobekli (and in many of the Tas Tepeler): his arms are in front of him, protecting his penis

‘Gobekli Tepe upends our view of human history. We always thought that agriculture came first, then civilisation: farming, pottery, social hierarchies. But here it is reversed, it seems the ritual centre came first, then when enough hunter gathering people collected to worship – or so I believe – they realised they had to feed people. Which means farming.’ He waved at the surrounding hills, ‘It is no coincidence that in these same hills in the Fertile Crescent men and women first domesticated the local wild einkorn grass, becoming wheat, and they also first domesticated pigs, cows and sheep. This is the place where Homo sapiens went from plucking the fruit from the tree, to toiling and sowing the ground.’

People were already speculating that – if you see the Garden of Eden mythos as an allegory of the Neolithic Revolution: i.e. our fall from the relative ease of hunter-gathering to the relative hardships of farming (and life did get harder when we first started farming, as we worked longer hours, and caught diseases from domesticated animals), then Gobekli Tepe and its environs is probably the place where this happened

‘I believe Gobekli Tepe is a temple in Eden’. It’s a quote I reused, to some controversy, because people took Klaus literally. But he did not mean it literally. He meant it allegorically.

This number is so large it is hard to take in. For comparison the Great Pyramid at Giza is 4,500 years old. Stonehenge is 5,000 years old. The Cairn de Barnenez tomb-complex in Brittany, perhaps the oldest standing structure in Europe, could be up to 7,000 years old.

I do definitely know this: some time in 8000 BC the creators of Gobekli Tepe buried their great structures under tons of rubble. They entombed it. We can speculate why. Did they feel guilt? Did they need to propitiate an angry God? Or just want to hide it?’ Klaus was also fairly sure on one other thing. ‘Gobekli Tepe is unique.’

These days Gobekli Tepe is not just a famous archaeological site, it is a Unesco World-Heritage-listed tourist honeypot which can generate a million visitors a year. It is all enclosed by a futuristic hi-tech steel-and-plastic marquee (no casual wandering around taking photos of the stones and workers

Necmi shows me the gleaming museum built to house the greatest finds from the region: including a 11,000 year old statue, retrieved from beneath the centre of Sanliurfa itself, and perhaps the world’s oldest life size carved human figure

‘We have found no homes, no human remains. Where is everyone, did they gather for festivals, then disperse? As for their religion, I have no real idea, perhaps Gobekli Tepe was a place of excarnation, for exposing the bones of the dead to be consumed by vultures, so the bodies have all gone

Aslan tells me how archaeologists at Gobekli have also, more recently, found tantalising evidence of alcohol: huge troughs with the chemical residue of fermentation, indicating mighty ritual feasts, maybe.

he explains how scientists at Karahan Tepe, as well as Gobekli Tepe, have now found evidence of homes.

The builders lived here. They ate their roasted game here. They slept here. And they used, it seems, a primitive but poetic form of pottery, shaped from polished stone. They possibly did elaborate manhood rituals in the Karahan Tepe penis chambe

Yet still we have no sign at all of contemporary agriculture; they were, it still appears, hunter gatherers, but of unnerving sophistication.

Another unnerving oddity is the curious number of carvings which show people with six fingers. Is this symbolic, or an actual deformity? Perhaps the mark of a strange tribe?

Karahan Tepe is stupefyingly big. ‘So far,’ he says, ‘We have dug up maybe 1 per cent of the site’ – and it is already impressive. I ask him how many pillars – T stones – might be buried here. He casually points at a rectangular rock peering above the dry grass. ‘That’s probably another megalith right there, waiting to be excavated. I reckon there are probably thousands more of them, all around us. We are only at the beginning. And there could be dozens more Tas Tepeler we have not yet found, spread over hundreds of kilometres.’

Karahan too was definitely and purposely buried. That is the reason Necmi and his team were able to unearth the penis pillars so quickly, all they had to do was scoop away the backfill, exposing the phallic pillars, sculpted from living rock.

the most remarkable answer of all, and it is this: archaeologists in southeastern Turkey are, at this moment, digging up a wild, grand, artistically coherent, implausibly strange, hitherto-unknown-to-us religious civilisation, which has been buried in Mesopotamia for ten thousand years. And it was all buried deliberately.

At the same time, the share of high school students who say they have had sexual intercourse has fallen 29 percent since 1991,

The share of female teens who did not use birth control the last time they had sex dropped by more than a third over the last decade, according to an analysis of government surveys by the Guttmacher Institute. The share using the most effective form, long-acting reversible contraception (delivered through an intrauterine device or arm implant), rose fivefold to 15 percent. The use of emergency contraception also rose.

“They’re going to school and seeing new career paths open,” said Melissa S. Kearney, an economist at the University of Maryland. “Whether they are excited about their own opportunities or feel that unreliable male partners leave them no choice, it leads them in the same direction — not becoming a young mother.”

Abortion does not appear to have driven the decline in teen births. As a share of teenage pregnancy, it has remained steady over the past decade,

If adolescent girls are more cautious with sex and birth control, what explains the caution? A common answer is that more feel they have something to lose. “There is just a greater confidence among young women that they have educational and professional opportunities,” Mr. Wilcox said.

t women in their mid-30s were nearly 25 percent more likely than men to have a four-year college degree, and at every educational level earnings had grown faster for women than men.

Skeptics see limits in the data and note that the payoff to education is growing.“I strongly disagree with the argument that teen births have no effect on social mobility,” said Isabel V. Sawhill of the Brookings Institution. “It’s a lot easier to move out of poverty if you’re not responsible for a child in your teenage years.”

The debate is more than academic. Some progressives worry that a narrow focus on preventing teen births will undermine broader anti-poverty plans and risks blaming adolescents for their poverty. Other see reducing poverty and teen births as complementary causes meant not to blame young women but empower them.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Berlin, like Washington, has tried to position itself as a concerned friend, intent on ensuring Israel’s long-term security by not allowing it to go so far that it loses even more international backing. But the stakes are high for Germany, too.

The country needs to maintain friendly relations around the world to pursue its own interests, whether Europe is cutting deals with Egypt to curb migration or seeking support for measures to back Ukraine against Russia

this week, Germany’s foreign minister, Annalena Baerbock, said she would be sending a delegation to Israel because as a signatory to the Geneva Conventions, her country “is obliged to remind all parties of their duty to abide by international humanitarian law.”

The sense of diminishing credibility on human rights is particularly strong in the set of developing or underdeveloped countries sometimes referred to as the Global South, a point brought home during a visit to Berlin this month by Malaysia’s prime minister, Anwar Ibrahim.

“We oppose colonialism, or apartheid, or ethnic cleansing, or dispossession of any country, be it in Ukraine, or in Gaza,” Mr. Ibrahim told journalists as he stood beside Mr. Scholz. “Where have we thrown our humanity? Why this hypocrisy?”

polls by public broadcasters in recent weeks show that nearly 70 percent of Germans surveyed felt Israel’s military actions were not justifiable; just a few weeks earlier, the number was around 50 percent.

On the one hand, she said, Germany was calling on Israel not to invade Rafah. On the other, Germany remained one of Israel’s biggest arms suppliers. “We have to really do something to protect these people.”
