Elon Musk is afraid that machines are getting smarter and smarter and he worries that they are an existential threat to humanity and may decide that they can rule over us or even worse, get rid of us. Leo thinks Musk has watched too many movies. Rodney Brooks, an artificial intelligence expert from MIT, said most people worried about that aren't working in AI, and he says that they aren't too worried because AI is too hard to perfect. Most are limited machines who can't move beyond their programming. It's a thin veneer of what looks like AI, but in reality, machines are pretty dumb. So it's too soon to start talking regulation.
