It's vastly more comforting to believe in an imminent robot apocalypse than the truth: the things that will destroy us are extensions of the unsexy but obvious problems all around us. We are not doomed in one grand way, but a thousand petty small ways.
Certain kinds of smart people tend to have a "sexy apocalypse" problem when it comes to thinking about risk. E.g. skynet turning everyone in paperclips, while bad, is also *kind of cool and fun* at the same time. Where the reality is that most actual disasters are both stupid and disappointing.
