Apple chief: driverless car venture is 'the mother of all AI projects'

Apple has shed new light on its top-secret driverless car project, as chief executive Tim Cook described the challenge of building autonomous vehicles as "the mother of all" artificial intelligence projects. Cook said Apple was ploughing resources into developing technology to control driverless vehicles, although he refused to rule out the Silicon Valley firm building its own car at some point. The Apple boss spoke as shares in his company and other US tech firms came under pressure this week amid investor concerns that a sector-wide boom is losing steam. Cook attempted to restore faith in Apple's ability to strike out into new territory by giving his most detailed comments yet about a car venture that has been shrouded in secrecy. "We're focusing on autonomous systems," said Cook in an interview with Bloomberg TV.
