But in recent years, as the Tel Aviv area has increasingly become a target of rocket attacks, the building has been judged unsafe.

In addition, Israel sits on two seismic faults that in the event of a major earthquake would leave only the lobby of the existing center intact.

The vault, 50 feet down, is cocooned in concrete and steel, and has a separate air supply and filtering system. Moshe Noyovich, the engineer overseeing the project, said the inventory of blood components stored in the vault should suffice for four or five days of war.

Scientists are only beginning to guess why the vaccine’s profile is improving with the passing months.

Levels of antibodies skyrocket in the first few weeks after immunization, but then rapidly wane. The J.&J. vaccine may produce antibodies that decline more slowly than those produced by the other vaccines, some research suggests. Or those antibodies may become more sophisticated over time, through a biological phenomenon called affinity maturation.

Perhaps, some researchers suggest, the vaccine offered a more robust defense against the Omicron variant, responsible for the huge increase in infections over the past few months. And studies have shown that the vaccine trains other parts of the immune system at least as well as the other two vaccines.

“It is a shame that we don’t have more direct study of outcomes among people who received J.&J.,” she said. That is in part because fewer people got the vaccine than the mRNA vaccines, she said, but also “because we’re relying on other countries generating data.”

Still, the data so far suggest that two doses of the J.&J. vaccine had an effectiveness of about 75 percent against hospitalization with the Omicron variant, comparable to the protection from the Pfizer-BioNTech vaccine. The researchers presented the findings last month at the Conference on Retroviruses and Opportunistic Infections in Denver.

Although the trial looked only at people who got two doses of the Johnson & Johnson vaccine, it suggests that the vaccine may make an excellent booster for people who initially got two doses of an mRNA vaccine, experts said.

Most religious faiths instruct us to welcome the strangers we encounter, and there’s good reason for this. If we engaged only with the people we knew, our world would be small.

That leap of faith toward the unknown other is what allows us to grow beyond the family unit, tribe or nation. Everyone you converse with who is not a biological relative — your best friend, neighbor, lover, spouse or even that chatty taxi driver from last weekend — was a stranger before you spoke to that person. Anytime we ignore strangers in our vicinity, whether because of fear, bigotry or the everyday convenience and efficiency of digital technology, we weaken that contract.

Far from random human inconveniences, strangers are actually one of the richest and most important resources we have. They connect us to the community, teach us empathy, build civility and are full of surprise and potentially wonder.

the small, transactional relationships we create by talking to strangers are important pillars of our social and emotional well-being.

“We have all these kinds of people who populate our lives, who we aren’t that close to and we don’t share our deepest, darkest secrets with,” said Dr. Sandstrom, who forces herself to speak to strangers every day, despite identifying as an introvert. “But they form this tapestry that when we’re not there, our life feels kind of empty.”

A study published last fall showed that despite our fears of awkwardness, deep, meaningful conversations with strangers are not only easier than expected but also left participants feeling better about themselves.

In some ways, our recent aversion to strangers is a byproduct of technological evolution. Sure, newspapers and magazines, cassette players and televisions were all potential distractions, but none of them fully normalized ignoring other people in the way that smartphones have. E-commerce sites and third-party restaurant delivery apps incentivize us against entering stores and restaurants filled with strangers

Then came the pandemic, and suddenly, each physical encounter with a stranger carried the potential of death. We were ordered to stay home, avoid public spaces and to speak only within our trusted bubbles.

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.

While sex is a category that refers broadly to physiology, a person's gender is an innate sense of identity. The factors that go into determining the sex listed on a birth certificate may include anatomy, genetics and hormones, and there is broad natural variation in each of these categories. For this reason, critics have said the language of "biological sex," as used in DeSantis' proclamation, is overly simplistic and misleading.A 2017 report in the journal Sports Medicine that reviewed several related studies found "no direct or consistent research" on trans people having an athletic advantage over their cisgender peers, at any state of their transition, and critics say postures like DeSantis' will only add to the discrimination that trans people face, particularly trans youth.

So far this year, Iowa and South Dakota have approved legislation banning transgender women and girls from participating on sports teams consistent with their gender at accredited schools and colleges. And last year, Alabama, Arkansas, Florida, Mississippi, Montana, Tennessee, Texas and West Virginia enacted similar sports bans, infuriating LGBTQ advocates, who argue conservatives are creating an issue where there isn't one.

Whether North Korea has mastered the technology needed to send an intercontinental nuclear warhead into space and then guide it back through the earth’s atmosphere to its target is still unclear.

North Korea’s short-range ballistic missile program has made big advances.

When North Korea resumed missile tests in 2019 following the collapse of the Kim-Trump talks, the tests featured three new missiles that used solid fuel, military experts said.

The North has also stockpiled thousands of tons of chemical and biological​ weapons​ ​agents​ that it can deliver with its missiles​​.

“My first and biggest wish is that we had known early that Covid-19 was airborne,”

, “Once you’ve realized that, it informs an entirely different strategy for protection.” Masking, ventilation and air cleaning become key, as well as avoiding high-risk encounters with strangers, he says.

Instead of washing our produce and wearing hand-sewn cloth masks, we could have made sure to avoid superspreader events and worn more-effective N95 masks or their equivalent. “We could have made more of an effort to develop and distribute N95s to everyone,” says Dr. Volckens. “We could have had an Operation Warp Speed for masks.”

We didn’t realize how important clear, straight talk would be to maintaining public trust. If we had, we could have explained the biological nature of a virus and warned that Covid-19 would change in unpredictable ways.  

In the face of a pandemic, he says, the public needs an early basic and blunt lesson in virology

“The science is really important, but if you don’t get the trust and communication right, it can only take you so far,”

and mutates, and since we’ve never seen this particular virus before, we will need to take unprecedented actions and we will make mistakes, he says.

Since the public wasn’t prepared, “people weren’t able to pivot when the knowledge changed,”

By the time the vaccines became available, public trust had been eroded by myriad contradictory messages—about the usefulness of masks, the ways in which the virus could be spread, and whether the virus would have an end date.

, the absence of a single, trusted source of clear information meant that many people gave up on trying to stay current or dismissed the different points of advice as partisan and untrustworthy.

We didn’t know how difficult it would be to get the basic data needed to make good public-health and medical decisions. If we’d had the data, we could have more effectively allocated scarce resources

For much of the pandemic, doctors, epidemiologists, and state and local governments had no way to find out in real time how many people were contracting Covid-19, getting hospitalized and dying

Doctors didn’t know what medicines worked. Governors and mayors didn’t have the information they needed to know whether to require masks. School officials lacked the information needed to know whether it was safe to open schools.

people didn’t know whether it was OK to visit elderly relatives or go to a dinner party.

just months before the outbreak of the pandemic, the Council of State and Territorial Epidemiologists released a white paper detailing the urgent need to modernize the nation’s public-health system still reliant on manual data collection methods—paper records, phone calls, spreadsheets and faxes.

While the U.K. and Israel were collecting and disseminating Covid case data promptly, in the U.S. the CDC couldn’t. It didn’t have a centralized health-data collection system like those countries did, but rather relied on voluntary reporting by underfunded state and local public-health systems and hospitals.

doctors and scientists say they had to depend on information from Israel, the U.K. and South Africa to understand the nature of new variants and the effectiveness of treatments and vaccines. They relied heavily on private data collection efforts such as a dashboard at Johns Hopkins University’s Coronavirus Resource Center that tallied cases, deaths and vaccine rates globally.

With good data, Dr. Ranney says, she could have better managed staffing and taken steps to alleviate the strain on doctors and nurses by arranging child care for them.

To solve the data problem, Dr. Ranney says, we need to build a public-health system that can collect and disseminate data and acts like an electrical grid. The power company sees a storm coming and lines up repair crews.

If we’d known how damaging lockdowns would be to mental health, physical health and the economy, we could have taken a more strategic approach to closing businesses and keeping people at home.

t many doctors say they were crucial at the start of the pandemic to give doctors and hospitals a chance to figure out how to accommodate and treat the avalanche of very sick patients.

The measures reduced deaths, according to many studies—but at a steep cost.

The lockdowns didn’t have to be so harmful, some scientists say. They could have been more carefully tailored to protect the most vulnerable, such as those in nursing homes and retirement communities, and to minimize widespread disruption.

Lockdowns could, during Covid-19 surges, close places such as bars and restaurants where the virus is most likely to spread, while allowing other businesses to stay open with safety precautions like masking and ventilation in place.  

If England’s March 23, 2020, lockdown had begun one week earlier, the measure would have nearly halved the estimated 48,600 deaths in the first wave of England’s pandemic

If the lockdown had begun a week later, deaths in the same period would have more than doubled

The key isn’t to have the lockdowns last a long time, but that they are deployed earlier,

It is possible to avoid lockdowns altogether. Taiwan, South Korea and Hong Kong—all countries experienced at handling disease outbreaks such as SARS in 2003 and MERS—avoided lockdowns by widespread masking, tracking the spread of the virus through testing and contact tracing and quarantining infected individuals.

Had we known that even a mild case of Covid-19 could result in long Covid and other serious chronic health problems, we might have calculated our own personal risk differently and taken more care.

Early in the pandemic, public-health officials were clear: The people at increased risk for severe Covid-19 illness were older, immunocompromised, had chronic kidney disease, Type 2 diabetes or serious heart conditions

t had the unfortunate effect of giving a false sense of security to people who weren’t in those high-risk categories. Once case rates dropped, vaccines became available and fear of the virus wore off, many people let their guard down, ditching masks, spending time in crowded indoor places.

it has become clear that even people with mild cases of Covid-19 can develop long-term serious and debilitating diseases. Long Covid, whose symptoms include months of persistent fatigue, shortness of breath, muscle aches and brain fog, hasn’t been the virus’s only nasty surprise

In February 2022, a study found that, for at least a year, people who had Covid-19 had a substantially increased risk of heart disease—even people who were younger and had not been hospitalized

respiratory conditions.

Some scientists now suspect that Covid-19 might be capable of affecting nearly every organ system in the body. It may play a role in the activation of dormant viruses and latent autoimmune conditions people didn’t know they had

 A blood test, he says, would tell people if they are at higher risk of long Covid and whether they should have antivirals on hand to take right away should they contract Covid-19.

If the risks of long Covid had been known, would people have reacted differently, especially given the confusion over masks and lockdowns and variants? Perhaps. At the least, many people might not have assumed they were out of the woods just because they didn’t have any of the risk factors.

Labour’s troubles don’t end there. For months Starmer and his shadow cabinet have tied themselves in knots attempting to answer what appears to be a rather basic question: can a woman have a penis?

Starmer’s failure to articulate a simple position has put him on a collision course with feminist groups and his own MP Rosie Duffield, who has claimed that the party has a “women problem”

he says: “For 99.9 per cent of women, it is completely biological . . . and of course they haven’t got a penis.”

According to the 2021 census, 262,000 people in Britain — 0.5 per cent of the population — stated that their gender identity was different to their sex registered at birth. Of those, 48,000 — 0.1 per cent — identified as a trans woman.

Starmer says: “Look, of course I’d want to know. I say that as a parent. I would want to know and I think the vast majority of parents would want to know. That’s why we have to have national guidance on it and they should try to make it cross-party, because it’s not helpful to parents or schools to have this as just a toxic divide when what’s needed is practical, common sense advice.

He adds: “There are some people who identify as a different gender to the one they are born with. It’s a very small number and that is why the Gender Recognition Act was passed [in 2004].

“To recognise that they need legal support and a framework and most people don’t disagree with that, and that’s the framework within which we ought to look at these issues. But simply turning it into a toxic divide advances the cause of no one, the cause of women or those that don’t identify with the gender that they were born into.

And it’s also a pattern of behaviour of the last ten years which is now turning everything into a toxic culture, when it possibly can, which is the last resort of politicians who have nothing substantive to say on the issue.”

On the subject of children, Starmer, who has a son and daughter with his wife, Victoria, is also clear that there is a need for greater transparency from teachers

only 39 out of 140 English secondary schools were “reliably informing” parents when pupils identified as trans or questioned their gender.

In an attempt to win back the support of gender critical campaigners and MPs, Starmer is eager to stress that there will be “no rolling back” on women’s hard-won rights, saying: “I think there is a fear that somehow there could be the rolling back of some of the things that have been won. There are still many battles that need to go ahead for women and I don’t think we should roll anything back. I think we should go on to win the next battles for women. And that is a very important sort of starting point for this debate.”

he is clear that in order for Labour to overturn the Tories’ majority — which was a historic 80 seats at the 2019 election — it will require him to stick to his three-part plan for power: to change the party, expose the government’s failings, and have the answers to the challenges facing the country.

“You’ve got to have a race strategy. And my strategy was that you’ve got to be in the leading pack as you go round the track three and three-quarter times. But you shouldn’t hit the front too early

each time you go round the lap, there are people on the side going: go faster, pump harder . . . And what we’ve had to do over the last three years is to keep the discipline, which is that we have got a strategy, we are operating to it and there is such a determination to get us over the finishing line, which would be such an incredible achievement if we can go from the disastrous defeat of the 2019 election into power.”

second, the people inventing them think they are potentially incredibly dangerous: ten percent of them, in fact, think they might extinguish the human species. They don’t know exactly how, but think Sorcerer’s Apprentice (or google ‘paper clip maximizer.’)

One pundit after another explains that an AI program called Deep Mind worked far faster than scientists doing experiments to uncover the basic structure of all the different proteins, which will allow quicker drug development. It’s regarded as ipso facto better because it’s faster, and hence—implicitly—worth taking the risks that come with AI.

That is, it seems to me, a dumb answer from smart people—the answer not of people who have thought hard about ethics or even outcomes, but the answer that would be supplied by a kind of cultist.

(Probably the kind with stock options).

it does go, fairly neatly, with the default modern assumption that if we can do something we should do it, which is what I want to talk about. The question that I think very few have bothered to answer is, why?

But why? The sun won’t blow up for a few billion years, meaning that if we don’t manage to drive ourselves to extinction, we’ve got all the time in the world. If it takes a generation or two for normal intelligence to come up with the structure of all the proteins, some people may die because a drug isn’t developed in time for their particular disease, but erring on the side of avoiding extinction seems mathematically sound

Allowing that we’re already good enough—indeed that our limitations are intrinsic to us, define us, and make us human—should guide us towards trying to shut down this technology before it does deep damage.

The other challenge that people cite, over and over again, to justify running the risks of AI is to “combat climate change,

As it happens, regular old intelligence has already give us most of what we need: engineers have cut the cost of solar power and windpower and the batteries to store the energy they produce so dramatically that they’re now the cheapest power on earth

We don’t actually need artificial intelligence in this case; we need natural compassion, so that we work with the necessary speed to deploy these technologies.

Beyond those, the cases become trivial, or worse

All of this is a way of saying something we don’t say as often as we should: humans are good enough. We don’t require improvement. We can solve the challenges we face, as humans.

It may take us longer than if we can employ some “new form of intelligence,” but slow and steady is the whole point of the race.

Unless, of course, you’re trying to make money, in which case “first-mover advantage” is the point

I find they often answer from something that sounds like the A.I.’s perspective. Many — not all, but enough that I feel comfortable in this characterization — feel that they have a responsibility to usher this new form of intelligence into the world.”

here’s the thing: pausing, slowing down, stopping calls on the one human gift shared by no other creature, and perhaps by no machine. We are the animal that can, if we want to, decide not to do something we’re capable of doing.

n individual terms, that ability forms the core of our ethical and religious systems; in societal terms it’s been crucial as technology has developed over the last century. We’ve, so far, reined in nuclear and biological weapons, designer babies, and a few other maximally dangerous new inventions

It’s time to say do it again, and fast—faster than the next iteration of this tech.

Cambridge Students’ Union recently published a guide titled ‘How to spot Terf ideology’. It suggests that sex is neither natural nor binary, but rather a social construct and a ‘colonial fiction created to oppress trans people’

The guide goes on to claim, falsely, that ‘Terfs spend a lot of time working with the far-right.’  The Union’s Women’s Officer proudly announces in her manifesto that ‘Terfs aren’t welcome here’.

It is not uncommon for students to comb through a classmate’s social media and bully them in private messages. This can progress to more threatening behaviour. 

A gender-critical student at Cambridge was traumatised after her peers discovered an online article in which she expressed her views on sex. It cited her sexual assault as a reason for her reservations about allowing males into women’s spaces. For holding these views, she was publicly shamed and harassed. In the first year of what should have been a rewarding university experience, she became a pariah within her college

Helen Joyce, author of the best-selling book Trans: When Ideology Meets Reality, was recently invited to speak at Gonville and Caius College by Professor Arif Ahmed. This event sparked a furore. In an email to Caius students, the college’s Master and another academic described Joyce’s views as ‘hateful’ and wrote that: ‘Individuals should be able to speak freely within the law…However, on some issues which affect our community we cannot stay neutral’. Ahmed was blocked from using the college’s intranet to publicise the event.

Hundreds of students vehemently protested Joyce’s speech. Yet, in their report of the event, the student newspaper, Varsity muddled up what Joyce actually stood for. The paper suggested Joyce believes that ‘gender is not a social construct and is immutably linked to sex’, the very opposite of her thesis.

At one of this country’s most prestigious universities, women who hold perfectly reasonable views are terrorised into silence. Gender-critical students and academics are ostracised. A university that prides itself on academic rigour is letting down its students.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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