Now imagine that this is not facebook's AI trying to get more engagement, but a global AI that has humanity's best interest as a goal: preventing wars and famines, greater good for greater number sort of thing. What if the ultimate good AI decided that the best way to achieve it was by killing off a handful of possibly innocent people every year. It's not even necessary to kill future Hitlers, just find one random dude in Minnesota that would tip the balance and push him to off himself. I think this would make for a great novel, kind of a mashup of Asimov's robots and Ada Palmer.
