“I’m increasingly inclined to think that there should be some regulatory oversight at the national and international level just to make sure that we don’t do something very foolish. With artificial intelligence, we are summoning the demon,” said Elon Musk, CEO of Tesla Motors

I think the fear is less about AI being “evil” in the traditional sense.. but more just not really caring at all about humanity. It would most likely view humans as we view an ant colony that gets in the way of our yard work. “It was for the greater good”.
