Geoffrey Hinton hopes the prize will add credibility to his claims about the dangers of AI technology he pioneered
4 min
The newly minted Nobel laureate Geoffrey Hinton has a message about the artificial-intelligence systems he helped create: get more serious about safety or they could endanger humanity.
“I think we’re at a kind of bifurcation point in history where, in the next few years, we need to figure out if there’s a way to deal with that threat,” Hinton said in an interview Tuesday with a Nobel Prize official that mixed pride in his life’s work with warnings about the growing danger it poses.
The 76-year-old Hinton resigned from Google last year in part so he could talk more about the possibility that AI systems could escape human control and influence elections or power dangerous robots. Along with other experienced AI researchers, he has called on such companies as OpenAI, Meta Platforms and Alphabet -owned Google to devote more resources to the safety of the advanced systems that they are competing against each other to develop as quickly as possible.
Hinton’s Nobel win has provided a new platform for his doomsday warnings at the same time it celebrates his critical role in advancing the technologies fuelling them. Hinton has argued that advanced AI systems are capable of understanding their outputs, a controversial view in research circles.
“Hopefully, it will make me more credible when I say these things really do understand what they’re saying,” he said of the prize.
Hinton’s views have pitted him against factions of the AI community that believe dwelling on doomsday scenarios needlessly slows technological progress or distracts from more immediate harms, such as discrimination against minority groups .
“I think that he’s a smart guy, but I think a lot of people have way overhyped the risk of these things, and that’s really convinced a lot of the general public that this is what we should be focusing on, not the more immediate harms of AI,” said Melanie Mitchell, a professor at the Santa Fe Institute, during a panel last year.
Hinton visited Google’s Silicon Valley headquarters Tuesday for an informal celebration, and some of the company’s top AI executives congratulated him on social media.
On Wednesday, other prominent Googlers specialising in AI were also awarded a Nobel Prize . Demis Hassabis, chief executive of Google DeepMind, and John M. Jumper, director at the AI lab, were part of a group of three scientists who won the chemistry prize for their work on predicting the shape of proteins.
Hinton is sharing the Nobel Prize in physics with John Hopfield of Princeton University for their work since the 1980s on neural networks that process information in ways inspired by the human brain. That work is the basis for many of the AI technologies in use today, from ChatGPT’s humanlike conversations to Google Photos’ ability to recognize who is in every picture you take.
“Their contributions to connect fundamental concepts in physics with concepts in biology, not just AI—these concepts are still with us today,” said Yoshua Bengio , an AI researcher at the University of Montreal.
In 2012, Hinton worked with two of his University of Toronto graduate students, Alex Krizhevsky and Ilya Sutskever, on a neural network called AlexNet programmed to recognise images in photos. Until that point, computer algorithms had often been unable to tell that a picture of a dog was really a dog and not a cat or a car.
AlexNet’s blowout victory at a 2012 contest for image-recognition technology was a pivotal moment in the development of the modern AI boom, as it proved the power of neural nets over other approaches.
That same year, Hinton started a company with Krizhevsky and Sutskever that turned out to be short-lived. Google acquired it in 2013 in an auction against competitors including Baidu and Microsoft, paying $44 million essentially to hire the three men, according to the book “Genius Makers.” Hinton began splitting time between the University of Toronto and Google, where he continued research on neural networks.
Hinton is widely revered as a mentor for the current generation of top AI researchers including Sutskever, who co-founded OpenAI before leaving this spring to start a company called Safe Superintelligence.
Hinton received the 2018 Turing Award, a computer-science prize, for his work on neural networks alongside Bengio and a fellow AI researcher, Yann LeCun . The three are often referred to as the modern “godfathers of AI.”
By 2023, Hinton had become alarmed about the consequences of building more powerful artificial intelligence. He began talking about the possibility that AI systems could escape the control of their creators and cause catastrophic harm to humanity. In doing so, he aligned himself with a vocal movement of people concerned about the existential risks of the technology.
“We’re in a situation that most people can’t even conceive of, which is that these digital intelligences are going to be a lot smarter than us, and if they want to get stuff done, they’re going to want to take control,” Hinton said in an interview last year.
Hinton announced he was leaving Google in spring 2023, saying he wanted to be able to freely discuss the dangers of AI without worrying about consequences for the company. Google had acted “very responsibly,” he said in an X post.
In the subsequent months, Hinton has spent much of his time speaking to policymakers and tech executives, including Elon Musk , about AI risks.
Hinton cosigned a paper last year saying companies doing AI work should allocate at least one-third of their research and development resources to ensuring the safety and ethical use of their systems.
“One thing governments can do is force the big companies to spend a lot more of their resources on safety research, so that for example companies like OpenAI can’t just put safety research on the back burner,” Hinton said in the Nobel interview.
An OpenAI spokeswoman said the company is proud of its safety work.
With Bengio and other researchers, Hinton supported an artificial-intelligence safety bill passed by the California Legislature this summer that would have required developers of large AI systems to take a number of steps to ensure they can’t cause catastrophic damage. Gov. Gavin Newsom recently vetoed the bill , which was opposed by most big tech companies including Google.
Hinton’s increased activism has put him in opposition to other respected researchers who believe his warnings are fantastical because AI is far from having the capability to cause serious harm.
“Their complete lack of understanding of the physical world and lack of planning abilities put them way below cat-level intelligence, never mind human-level,” LeCun wrote in a response to Hinton on X last year.

Subsidised minivans, no income taxes: Countries have rolled out a range of benefits to encourage bigger families, with no luck
7 min
Imagine if having children came with more than $150,000 in cheap loans, a subsidised minivan and a lifetime exemption from income taxes.
Would people have more kids? The answer, it seems, is no.
These are among the benefits—along with cheap child care, extra vacation and free fertility treatments—that have been doled out to parents in different parts of Europe, a region at the forefront of the worldwide baby shortage. Europe’s overall population shrank during the pandemic and is on track to contract by about 40 million by 2050, according to United Nations statistics.
Birthrates have been falling across the developed world since the 1960s. But the decline hit Europe harder and faster than demographers expected—a foreshadowing of the sudden drop in the U.S. fertility rate in recent years.
Reversing the decline in birthrates has become a national priority among governments worldwide, including in China and Russia , where Vladimir Putin declared 2024 “the year of the family.” In the U.S., both Kamala Harris and Donald Trump have pledged to rethink the U.S.’s family policies . Harris wants to offer a $6,000 baby bonus. Trump has floated free in vitro fertilisation and tax deductions for parents.
Europe and other demographically challenged economies in Asia such as South Korea and Singapore have been pushing back against the demographic tide with lavish parental benefits for a generation. Yet falling fertility has persisted among nearly all age groups, incomes and education levels. Those who have many children often say they would have them even without the benefits. Those who don’t say the benefits don’t make enough of a difference.
Two European countries devote more resources to families than almost any other nation: Hungary and Norway. Despite their programs, they have fertility rates of 1.5 and 1.4 children for every woman, respectively—far below the replacement rate of 2.1, the level needed to keep the population steady. The U.S. fertility rate is 1.6.
Demographers suggest the reluctance to have kids is a fundamental cultural shift rather than a purely financial one.
“I used to say to myself, I’m too young. I have to finish my bachelor’s degree. I have to find a partner. Then suddenly I woke up and I was 28 years old, married, with a car and a house and a flexible job and there were no more excuses,” said Norwegian Nancy Lystad Herz. “Even though there are now no practical barriers, I realised that I don’t want children.”
Both Hungary and Norway spend more than 3% of GDP on their different approaches to promoting families—more than the amount they spend on their militaries, according to the Organization for Economic Cooperation and Development.
Hungary says in recent years its spending on policies for families has exceeded 5% of GDP. The U.S. spends around 1% of GDP on family support through child tax credits and programs aimed at low-income Americans.
Hungary’s subsidised housing loan program has helped almost 250,000 families buy or upgrade their homes, the government says. Orsolya Kocsis, a 28-year-old working in human resources, knows having kids would help her and her husband buy a larger house in Budapest, but it isn’t enough to change her mind about not wanting children.
“If we were to say we’ll have two kids, we could basically buy a new house tomorrow,” she said. “But morally, I would not feel right having brought a life into this world to buy a house.”
Promoting baby-making, known as pro natalism, is a key plank of Prime Minister Viktor Orbán ’s broader populist agenda . Hungary’s biennial Budapest Demographic Summit has become a meeting ground for prominent conservative politicians and thinkers. Former Fox News anchor Tucker Carlson and JD Vance, Trump’s vice president pick, have lauded Orbán’s family policies.
Orbán portrays having children inside what he has called a “traditional” family model as a national duty, as well as an alternative to immigration for growing the population. The benefits for child-rearing in Hungary are mostly reserved for married, heterosexual, middle-class couples. Couples who divorce lose subsidised interest rates and in some cases have to pay back the support.
Hungary’s population, now less than 10 million, has been shrinking since the 1980s. The country is about the size of Indiana.
“Because there are so few of us, there’s always this fear that we are disappearing,” said Zsuzsanna Szelényi, program director at the CEU Democracy Institute and author of a book on Orbán.
Hungary’s fertility rate collapsed after the fall of the Soviet Union and by 2010 was down to 1.25 children for every woman. Orbán, a father of five, and his Fidesz party swept back into power that year after being ousted in the early 2000s. He expanded the family support system over the next decade.
Hungary’s fertility rate rose to 1.6 children for every woman in 2021. Ivett Szalma, an associate professor at Corvinus University of Budapest, said that like in many other countries, women in Hungary who had delayed having children after the global financial crisis were finally catching up.
Then progress stalled. Hungary’s fertility rate has fallen for the past two years. Around 51,500 babies have been born there this year through August, a 10% drop compared with the same period last year. Many Hungarian women cite underfunded public health and education systems and difficulties balancing work and family as part of their hesitation to have more children.
Anna Nagy, a 35-year-old former lawyer, had her son in January 2021. She received a loan of about $27,300 that she didn’t have to start paying back until he turned 3. Nagy had left her job before getting pregnant but still received government-funded maternity payments, equal to 70% of her former salary, for the first two years and a smaller amount for a third year.
She used to think she wanted two or three kids, but now only wants one. She is frustrated at the implication that demographic challenges are her responsibility to solve. Economists point to increased immigration and a higher retirement age as other offsets to the financial strains on government budgets from a declining population.
“It’s not our duty as Hungarian women to keep the nation alive,” she said.
Hungary is especially generous to families who have several children, or who give birth at younger ages. Last year, the government announced it would restrict the loan program used by Nagy to women under 30. Families who pledge to have three or more children can get more than $150,000 in subsidised loans. Other benefits include a lifetime exemption from personal taxes for mothers with four or more kids, and up to seven extra annual vacation days for both parents.
Under another program that’s now expired, nearly 30,000 families used a subsidy to buy a minivan, the government said.
Critics of Hungary’s family policies say the money is wasted on people who would have had large families anyway. The government has also been criticised for excluding groups such as the minority Roma population and poorer Hungarians. Bank accounts, credit histories and a steady employment history are required for many of the incentives.
Orbán’s press office didn’t respond to requests for comment. Tünde Fűrész, head of a government-backed demographic research institute, disagreed that the policies are exclusionary and said the loans were used more heavily in economically depressed areas.
Government programs weren’t a determining factor for Eszter Gerencsér, 37, who said she and her husband always wanted a big family. They have four children, ages 3 to 10.
They received about $62,800 in low-interest loans through government programs and $35,500 in grants. They used the money to buy and renovate a house outside of Budapest. After she had her fourth child, the government forgave $11,000 of the debt. Her family receives a monthly payment of about $40 a month for each child.
Most Hungarian women stay home with their children until they turn 2, after which maternity payments are reduced. Publicly run nurseries are free for large families like hers. Gerencsér worked on and off between her pregnancies and returned full-time to work, in a civil-service job, earlier this year.
She still thinks Hungarian society is stacked against mothers and said she struggled to find a job because employers worried she would have to take lots of time off.
The country’s international reputation as family-friendly is “what you call good marketing,” she said.
Norway has been incentivising births for decades with generous parental leave and subsidised child care. New parents in Norway can share nearly a year of fully paid leave, or around 14 months at 80% pay. More than three months are reserved for fathers to encourage more equal caregiving. Mothers are entitled to take at least an hour at work to breast-feed or pump.
The government’s goal has never been explicitly to encourage people to have more children, but instead to make it easier for women to balance careers and children, said Trude Lappegard, a professor who researches demography at the University of Oslo. Norway doesn’t restrict benefits for unmarried parents or same-sex couples.
Its fertility rate of 1.4 children per woman has steadily fallen from nearly 2 in 2009. Unlike Hungary, Norway’s population is still growing for now, due mostly to immigration.
“It is difficult to say why the population is having fewer children,” Kjersti Toppe, the Norwegian Minister of Children and Families, said in an email. She said the government has increased monthly payments for parents and has formed a committee to investigate the baby bust and ways to reverse it.
More women in Norway are childless or have only one kid. The percentage of 45-year-old women with three or more children fell to 27.5% last year from 33% in 2010. Women are also waiting longer to have children—the average age at which women had their first child reached 30.3 last year. The global surge in housing costs and a longer timeline for getting established in careers likely plays a role, researchers say. Older first-time mothers can face obstacles: Women 35 and older are at higher risk of infertility and pregnancy complications.
Gina Ekholt, 39, said the government’s policies have helped offset much of the costs of having a child and allowed her to maintain her career as a senior adviser at the nonprofit Save the Children Norway. She had her daughter at age 34 after a round of state-subsidised IVF that cost about $1,600. She wanted to have more children but can’t because of fertility issues.
She receives a monthly stipend of about $160 a month, almost fully offsetting a $190 monthly nursery fee.
“On the economy side, it hasn’t made a bump. What’s been difficult for me is trying to have another kid,” she said. “The notion that we should have more kids, and you’re very selfish if you have only had one…those are the things that took a toll on me.”
Her friend Ewa Sapieżyńska, a 44-year-old Polish-Norwegian writer and social scientist with one son, has helped her see the upside of the one-child lifestyle. “For me, the decision is not about money. It’s about my life,” she said.
