- Both scientists expressed surprise at winning in the field of physics
Geoffrey Hinton and John Hopfield have been awarded the 2024 Nobel Prize in Physics for their groundbreaking work in artificial intelligence (AI) and neural networks.
The Royal Swedish Academy of Sciences announced the prize on Tuesday, recognizing the scientists’ contributions to machine learning technology that has revolutionized how computers process information.
Hinton, a 76-year-old British-Canadian computer scientist often called the “godfather of AI,” shares the award with John Hopfield, 91, an American scientist based at Princeton University. Their research in the late 1970s and early 1980s laid the foundations for modern machine learning systems that power many of today’s AI tools.
The Nobel Committee highlighted how Hinton and Hopfield applied concepts from physics to develop methods that form the basis of today’s powerful machine learning algorithms.
Their work on artificial neural networks, which mimic the function of neurons in the human brain, has enabled computers to recognize patterns in large datasets and perform tasks like image and speech recognition.
Hinton expressed surprise at receiving the physics prize, noting that his work is more closely aligned with computer science. “I’m flabbergasted. I had no idea this would happen,” he said when contacted by the Nobel Committee. Hopfield similarly described himself as “astonished” by the award.
While celebrating their achievements, both scientists also addressed concerns about the rapid advancement of AI technology. Hinton, who recently left his position at Google to speak more freely about potential risks, warned that AI’s growing capabilities could pose significant challenges for society.
“Quite a few good researchers believe that sometime in the next 20 years, AI will become more intelligent than us, and we need to think hard about what happens then,”
Hinton cautioned. He compared the potential impact of AI to that of the Industrial Revolution, noting that it could bring enormous benefits in areas like healthcare and productivity, but also carries risks if not properly managed.
Hopfield echoed these sentiments, drawing parallels between AI and other transformative technologies like nuclear energy. He emphasized the importance of developing ways to control AI systems and prevent potential disasters.
The Nobel Prize in Physics is typically associated with discoveries in fundamental physics, but the committee’s decision to recognize AI research underscores the growing importance of the field in scientific advancement.
Ellen Moons, a member of the Nobel Committee, explained that neural networks have not only advanced physics research but have become deeply embedded in daily life, citing examples like facial recognition and language translation.
The prize, which includes a cash award of 11 million Swedish kronor (approximately $1 million), will be officially presented at a ceremony on December 10. Both Hinton and Hopfield expressed hope that the recognition would bring more attention to the importance of AI safety and ethical development.
