What will happen when robots become smarter than humans – will they want to kill us? His name is Ilya Sutskever and he believes that super intelligent machines won't hate us, but they will prioritise their own survival. Think about the way we treat animals. We're fond of them but we don't ask their permission to build a road; it'll be like that. His analogy is an extraordinary moment in this doom-laden documentary about the future of AI from Norwegian film-maker Tonje Hessen Schei – an eye-opening film if your anxiety levels are up to it. Another interviewee jokes that AI is being developed by a few companies and a handful of governments for three purposes – "killing, spying and brainwashing" and the film then briskly rattles through the worst-case scenarios facing human civilisation.
