Humans will love, marry robots by 2050

An artificial intelligence researcher predicts that robotics will make such dramatic advances in the coming years that humans will be marrying robots by the year 2050.

Robots will become so human-like -- having intelligent conversations, displaying emotions and responding to human emotions -- that they'll be very much like a new race of people, said David Levy, a British artificial intelligence researcher in his book, "Love and Sex with Robots".
