Why scientists have set Doomsday Clock closer than ever to end of the world, thanks also to AI

The Bulletin of Atomic Scientists has moved its symbolic Doomsday Clock one second closer to midnight, with artificial intelligence aka AI emerging as a new existential threat alongside nuclear weapons and climate change.

The clock now stands at a mere 89 seconds to midnight – the closest it has ever been to the metaphorical point of global catastrophe, since 2022, when the clock was set to 90 seconds to midnight after Russia invaded Ukraine.
