Vnlr: I wish someone would make a true AI that takes control over humanity without exterminating it, which then proceeds to govern us in a very well-thought out manner.
(we'll still be ruled over by a faraway untouchable entity, on whose governmental decisions we'll have no influence, but at least there will be a sense of logic in the way we are being governed)
...the above should not be taken *too* seriously, of course...
Granted, but it turns out that the AI has a bug. Someone manages to break free of the control (thanks to the bug) and then discovers a way to exploit that bug, tricking the AI into executing arbitrary code, and uses it to exterminate humanity anyway.
I wish that cisphobia were a thing. (Additional constraint: The post that corrupts this wish must not use the word "trans" or any word containing it.)
