John J. Hopfield and Geoffrey E. Hinton have been awarded the 2024 Nobel Prize in Physics for their contributions to the foundation of modern machine learning. The prize recognizes their use of tools from physics to develop methods for storing and reconstructing information, and their invention of artificial neural networks that have revolutionized society. Hinton's work on neural networks in the 1980s laid the groundwork for machine learning technology, while Hopfield's associative memory framework can store and reconstruct images. The pair's research has raised concerns about the dangers of machines that could outsmart humans, as Hinton himself warned in 2023 when he resigned from Google to advocate for the responsible use of AI. The Nobel Prize in Physics is awarded by the Royal Swedish Academy of Sciences, and the prize sum is shared between the winners if there are multiple awardees.

    1. While machine learning has enormous benefits, its rapid development has also raised concerns about our future. Collectively, humans carry the responsibility for using this new technology in a safe and ethical way for the greatest benefit of humankind.
    2. We can recognize images and speech, and associate them with memories and past experiences — billions of neurons wired together give us unique cognitive abilities.
    3. The laureates' work has already been of the greatest benefit. In physics we use artificial neural networks in a vast range of areas, such as developing new materials with specific properties.
    1. This year's laureates have conducted important work with artificial neural networks from the 1980s onward.
    2. When we talk about artificial intelligence, we often mean machine learning using artificial neural networks. This technology was originally inspired by the structure of the brain.
    1. But we also have to worry about a number of possible bad consequences, particularly the threat of these things getting out of control.
    2. If I hadn't done it, somebody else would have.
    3. This will be comparable with the industrial revolution. Machine learning will exceed people in intellectual abilities.
    4. Instead of exceeding people in physical strength, it's going to exceed people in intellectual ability. We have no experience of what it's like to have things smarter than us.
    5. I am flabbergasted, I had no idea this would happen, I am very surprised.
    1. Totally justified and totally courageous on the part of the committee. Because although Hopfield is a trained physicist, Hinton is not.
    2. Hopfield laid the groundwork and Hinton made it usable. He is a visionary. In the 90s, nobody really wanted to think about this new field. But he didn't give up. He is the picture of an inter-disciplinary researcher.
