The real source of concern perhaps is the 90% chance AI is used to kill 90% of humans. Just crash the global economy and supply chains and see how quickly major metro areas run out of food and gas.

And as someone else pointed out, it will almost certainly be at the intentional direction of a human or humans, not the paper clip maximizer.

The paperclip maximizer is also at the intentional direction of a human or humans.

It's not "AI surprises everyone by having a thing for paperclips", it is "idiot tells AI to maximise paperclips no matter what, and then it does exactly what it was told, more competently, tirelessly, studiously, and unquestioningly, than any human would ever be".
