Stark warnings from artificial intelligence researchers that advanced forms of the technology could wipe out humanity have raised questions over whether governments are moving fast enough to regulate it.

What are the potential dangers of "superintelligent" computer systems, and should we be worried?

What's the worst-case scenario?

AI experts have long described the threat as critical.

In 2023, hundreds of AI scientists and industry figures, including the heads of top U.S. labs, signed a "statement on AI extinction risk" calling for the issue to be treated as seriously as pandemics or nuclear war.

If an out-of-control future AI deems that humans are obstructing its goals, it could use robots to "synthesise and spread novel pathogens", said Stuart Russell, computer science professor at the University of California, Berkeley.

Or it could "convince people to initiate nuclear war, including by hacking into early warning systems", Russell, a prominent voice on AI safety, told AFP.

Such existential fears do not concern current AI systems, he stressed. But as the technology improves it could take lethal action beyond........
