‘A race it might be impossible to stop’: how worried should we be about AI?

Scientists are warning machine learning will soon outsmart humans - maybe it's time for us to take note

Last Monday an eminent, elderly British scientist lobbed a grenade into the febrile anthill of researchers and corporations currently obsessed with artificial intelligence or AI (aka, for the most part, a technology called machine learning). The scientist was Geoffrey Hinton, and the bombshell was the news that he was leaving Google, where he had been doing great work on machine learning for the last 10 years, because he wanted to be free to express his fears about where the technology he had played a seminal role in founding was heading.

To say that this was big news would be an epic understatement. The tech industry is a huge, excitable beast that is occasionally prone to outbreaks of irrational exuberance", ie madness. One recent bout of it involved cryptocurrencies and a vision of the future of the internet called Web3", which an astute young blogger and critic, Molly White, memorably describes as an enormous grift that's pouring lighter fluid on our already smoldering planet".
