An intelligence that reasons this way would be, in human terms, batshit insane and completely immoral. So, it seems unlikely that many or maybe any humans would experience it as "otherwise benign" if it had power over their lives.

And if we do get an all-powerful dictator, we will be screwed regardless of whether their governing intelligence is artificial or composed of a group of humans or of one human (with, say, powerful AIs serving them faithfully, or access to some other technology).
