Ai Researchers Say Elon Musk's Fears 'Not Completely Crazy.'

High-tech entrepreneur Elon Musk made headlines when he said artificial intelligence research is a danger to humanity, but researchers from some of the top U.S. universities say he's not so far off the mark.

"At first I was surprised and then I thought, 'this is not completely crazy,' " said Andrew Moore, dean of the School of Computer Science at Carnegie Mellon University. "I actually do think this is a valid concern and it's really an interesting one. It's a remote, far future danger but sometime we're going to have to think about it. If we're at all close to building these super-intelligent, powerful machines, we should absolutely stop and figure out what we're doing."

Musk, most well-known as the CEO of electric car maker Tesla Motors, and CEO and co-founder of SpaceX , caused a stir after he told an audience at an MIT symposium that artificial intelligence (AI), and research into it, poses a threat to humans.
