Elon Musk: forget North Korea, AI will start World War III

Tesla (TSLA) and SpaceX's CEO wasn't making doomsday predictions because North Korea is testing nuclear weapons. What's got Musk much more worried about world war is artificial intelligence. North Korea "should be low on our list of concerns for civilizational existential risk," Musk said in one of a series of posts on Twitter (TWTR, Tech30) early Monday. "Competition for AI superiority at national level most likely cause of WW3 imo," Musk said in another tweet, using the Internet short-hand for "in my opinion." The dire prediction was in response to a recent comment from Russian President Vladimir Putin.
