On Wednesday, Tesla CEO Elon Musk and Alibaba cofounder Jack Ma took the stage at the World AI Conference in Shanghai to debate artificial intelligence and its implications for humanity. As expected, Ma took a far more optimistic stance than Musk. Ma encouraged people to have faith in humanity, our creativity, and the future. "I don't think artificial intelligence is a threat," he said, to which Musk replied, "I don't know, man, that's like, famous last words." An edited transcript of the discussion follows.

If the robots take over, at least Elon Musk will be able to say "I told you so." The billionaire inventor loves to make the impossible possible, but he is deeply afraid of artificial intelligence (AI). On Twitter this weekend, Musk said that "we need to be super careful with AI," adding that they are "potentially more dangerous than nukes." If that weren't concerning enough, Musk followed up his statement with another tweet that read: "Hope we're not just the biological boot loader for digital superintelligence. Unfortunately, that is increasingly probable."
