A NOBEL physics prize winner warned today of the speed of artificial intelligence (AI) development, saying we need to be “very careful” and “very thoughtful.”

British-Canadian scientist Geoffrey Hinton said the pace of change in AI is “much faster” than he expected and there has not been enough time to complete the research he believes is required.

His work has laid the foundations for technology that allows computers to mimic human intelligence, but his recent efforts have centred on advocating for safer AI.
