Musk says Facebook's Zuckerberg naive about AI

Silicon Valley baron Elon Musk insulted rival billionaire Mark Zuckerberg on Tuesday, escalating a tech wizard war of words over whether robots will become smart enough to kill their human creators. "His understanding of the subject is limited," Musk said in a tweet about the Facebook Inc founder whose algorithms and other technology revolutionized social media and won 2 billion monthly active users. Previously, Zuckerberg was asked about Musk's views on the dangers of robots. In his response, Zuckerberg chided "naysayers" whose "doomsday scenarios" were "irresponsible." Zuckerberg and Musk, CEO of electric car maker Tesla Inc. and rocket company SpaceX, have been waging a debate at a distance over the past few days on the dangers of artificial intelligence.
