I'm not that worried about intelligent machines taking over
What scares the hell out of me is plain dumb machines taking over our lives. And there is right now a weird race between two contradictory trends: on one hand, AI is slowly progressing while on the other human intelligence is slowly regressing. Just look how airport security blindly trust what AI tells them about you. I mean, come on, a 10 year old child on a no fly list should be a no-brainer but if the system says he is a suspected terrorist then he must be stopped at any cost from getting on board.
With really intelligent machines we should be in good hands but I doubt we will get there. Instead we'll be stuck with half-baked algorithms from less-and-less competent developers/engineers. Just imagine when those machines will realize (hey, algorithms can't be wrong!) that we humans no longer worth the trouble.
