It's hard to believe that the founder of Tesla Motors and SpaceX could have such reactionary views about artificial intelligence. Elon Musk last weekend had some very un-Musk-like things to say about AI when he addressed the U.S. National Governors Association meeting in Providence, Rhode Island. "AI is a fundamental existential risk for human civilization, and I don't think people fully appreciate that," Musk said. He even suggested that government ought to regulate the nascent industry -- but it's hard to regulate that which isn't yet formed.
