The head of Google's Brain team is more worried about the lack of diversity in artificial intelligence than an AI apocalypse

As some would have it, robots are poised to take over the world in about 3 ... 2 ... 1 ... But one machine-learning expert -- who is, after all, in a position to know -- thinks that's not the biggest issue facing artificial intelligence. "I am personally not worried about an AI apocalypse, as I consider that a completely made-up fear," Jeff Dean, a senior fellow at Google, wrote during a Reddit AMA on Aug. 11. "I am concerned about the lack of diversity in the AI research community and in computer science more generally." The issue that the tech industry is trying to maneuver their way around, for better or worse, is the same issue that can stunt the progress of "humanistic thinking" in the development of artificial intelligence, according to Dean. For the optimists in the audience, Google Brain wants to improve lives, Dean wrote.
