We would do well to recall that Nick Bostrom is one of these thinkers. He first gained renown from his fiendishly constructed "we are The Matrix argument", in which he went from

The REAL problem is that so many people seem to think this is real thought, even profound thought, rather than superstitious twaddle. We look back at medieval theologians who worried about how many angels could dance on the head of a pin and think, "How silly." Yes, it's silly, but it seemed real enough to advanced thinkers at the time. These fears of superintelligent evil computers are just as silly. Get over it.
