Artificial intelligence systems could cause "major" incidents within two years without adequate steps to make them safe as capabilities grow, Google's DeepMind chair Demis Hassabis said on Wednesday. Speaking at an AI conference in Dublin, Hassabis described recent incidents as "early warning shots" fired by systems that "aren't that powerful yet." "So the incidents aren't that major, but they could be looking into next year and the next couple of years if we don't do more work as an industry and individually as companies and governments on securing these systems," he said.
