The hunt for AI.

Marcus Du Sautoy investigates the latest developments in the world of intelligent machines - robots and computers with artificial intelligence. He meets two robots who are developing their own private language and tries to talk with them. He also sees a super computer beat humans at Jeopardy, one of the hardest quiz shows on the planet. But can machines ever have creative intelligence and intuition? If so, they could take over from us. Or will they rather learn to live alongside us, with their own distinct way of thinking?
