But I cannot make the leap from "super intelligent" to "has access to all the levers of social and physical systems control" without the explicit, costly, and ongoing, effort of humans.
I also struggle with the conflation of "intelligent" and "has free will". Intelligent humans will argue that not even humans have free will. But assuming we do, when our free will contradicts the social structure, society reacts.
I see no reason to believe that the emergent properties of a highly complex system will include free will. Or curiosity, or a sense of humor. Or a soul. Or goals, or a concept of pleasure or pain, etc. And I think it's possible to be "intelligent" and even "sentient" (whatever that means) without those traits.
Honestly -- and I'm not making an accusation here(!) -- this fear of AI reminds me of the fear of replacement / status loss. We humans are at the top of the food chain on all scales we can measure, and we don't want to be replaced, or subjugated in the way that we presently subjugate other species.
This is a reasonable fear! Humans are often difficult to share a planet with. But I don't think it survives rational investigation.
If I'm wrong, I'll be very very wrong. I don't think it matters though, there is no getting off this train, and maybe there never was. There's a solid argument for being in the engine vs the caboose.
