Elon Musk says artificial intelligence is a bigger threat than North Koreaand a "fundamental risk to the existence of human civilization." He predicts a global race to develop artificial intelligence will result in World War 3.
Top Silicon Valley tech executive Sam Altman, who is president of Y Combinator, says that both Musk and Zuckerberg are right.
"Like many other arguments, both sides are correct," Altman tells CNBC Make It.
"It could be the greatest thing ever," he says. "I really do believe that, if we could eliminate a huge percentage of human suffering with AI.
"I also believe there will be down sides. Any super powerful technology is good and bad."
