Elon Musk's new plan to save humanity from AI

Elon Musk has a new plan to protect humanity from artificial intelligence -- if you can't beat'em, join'em. In October 2014, Musk ignited a global discussion on the perils of artificial intelligence. Humans might be doomed if we make machines that are smarter than us, Musk warned. He called artificial intelligence our greatest existential threat. Now he is hoping to harness AI in a way that will benefit society.
