Would even an AI disaster on the scale of Hiroshima be enough to make humankind protect itself? I fear not | Timothy Garton Ash

It’s clear here in Silicon Valley that AI is advancing faster than humans’ ability to control it. That means even sober prophecies seem optimistic Here in Silicon Valley, the experts think that within the next couple of years we’ll see an extraordinary takeoff for artificial intelligence. “Welcome to the foothills of the singularity,” as a Stanford University friend greeted me. More prosaically, the imminent breakthrough is described as “recursive self-improvement” – the point at which AI itself trains each successive model of AI, resulting in an exponential development to something which, in many significant respects, is more intelligent than us humans. As Robert Wright puts it in his book The God Test: “Never before has the near-term future … held such a wide array of not-implausible paths for humankind that would be so wildly transformative.” But will this be heaven or hell? Heaven, says Elon Musk, who predicts “an age of amazing abundance” – although he also sees a 10-20% chance of killer robots murdering us all. Hell is more likely according to Geoffrey Hinton, one of the intellectual founding fathers of AI. “My intuition is, we’re toast,” he told an interviewer in 2023. And talking to Sebastian Mallaby, author of The Infinity Machine, a book about the quest for superintelligence, Hinton estimates p(doom) – the probability of human extinction – at 50%, “because I haven’t got a clue how to estimate the real number”. “As soon as evolution [of AI] kicks in, we’re fucked,” he adds cheerfully. But whether it’s God or Godzilla, artificial superintelligence is just around the corner. Timothy Garton Ash is a Guardian columnist..
