If you're actually interested in understanding the arguments for worrying about AI safety, consider reading "Superintelligence" by Bostrom.

It's the closest approximation to a consensus statement / catalog of arguments by folks who take this position (although of course there is a whole spectrum of opinions). It also appears to be the book that convinced Musk that this is worth worrying about.

I recently listened to a pretty good Econtalk with Bostrom about this subject.
