Elon Musk just told a group of America's governors that we need to regulate AI before it's too late

But there is something that really scares Musk: Artificial Intelligence, and the idea of software and machines taking over their human creators. He's been warning people about AI for years, and today called it the "biggest risk we face as a civilization" when he spoke at the National Governors Association Summer Meeting in Rhode Island. Musk then called on the government to proactively regulate artificial intelligence before things advance too far. "Until people see robots going down the street killing people, they don't know how to react because it seems so ethereal," he said. "AI is a rare case where I think we need to be proactive in regulation instead of reactive. Because I think by the time we are reactive in AI regulation, it's too late."
