Apples CEO Tim Cook speaks out the future of AI

Pixar founder George Lucas might have given the world the word "Droid" before he sold the company to Apple's Steve Jobs but now Apple CEO Tim Cook is making no secret of the fact that he wants the company to play its part in bringing Artificial Intelligence to the world. This week he's been spilling at least some of the beans on Apple's plans for AI, although his vision seems more connected to machine learning rather than the AI technologies that would help to bring droids like C3PO and R2D2. "We see AI as being horizontal in nature and running across all our platforms and products," said Cook, following on to say, "we see it being used in ways that most people don't even think about." That sounds grandoise – and, at first sight, it sounds like they have something amazing up their sleeves. So just what kind of unexpected use cases was he talking about?
