Brainpower is so yesterday -- leave it to AI

Smart people are starting to worry about the brainpower of machines. A recent report from Harvard said the emergence of artificial intelligence as a weapon poses as much game-changing potential as the airplane and the nuclear bomb. They worry it could give small countries and terrorists the long-range strike capability of a superpower, the ability to crash our cyber systems and create a channel for fake news that would overwhelm our understanding of what's real and what's not. Elon Musk, the Tesla/Hyperloop/SpaceX dude prone to the grandiose, thinks unchecked artificial intelligence could become an existential threat to mankind. If we're not careful, he warns, we'll end up in a world where humans answer to machines and not the other way around.
