Musk continues to talk about the dangers of AI, saying he warned President Barack Obama in a meeting years before it was a serious concern. “There is no agreement to limit AI and so there is currently an AI acceleration that’s happening very quickly with a number of companies primarily in the US and with China,” he says. Back in 2015, he recalls, “I had many dinners with many people talking about AI safety” — one of those people was Sam Altman.
