Interesting comparison, though I think the 'beings' we perceive on entheogens are just reflections of our own psyche rather than actual self-replicating machine elves from another dimension
I think your dismissal of the doomers concerns is a bit premature, a case can be made that instead of the existing central authorities (however you define them) losing control of the broader population they will instead gain an even greater and more granular level of control. While AI can have a democratizing effect in some areas like art/music/etc., in others it will be the opposite- IE. more efficient dragnet surveillance and autonomous killer drone swarms
