As for the emergent path, that is the standard explanation of human intelligence—not saying it’s right—the argument is that artificial intelligence, housed in silicon bodies, the net or anywhere (in theory it could be atoms interacting.) Consciousness is viewed either as side effect of intelligence or a continuing mystery.
The inhabiting path I’m approaching from another angle.
The question is not whether AI can inhabit something else, but whether something else can inhabit AI. Are there types of consciousness that can inhabit AI? I think that’s an open question. Given that we could impute consciousness of the lowest sort to a rock or a can opener—either on the inhabit path or the everything is consciousness path (a third path but quite common these days), I’m not sure why code is an insufficient basis for consciousness. Not saying the simulation hypothesis is true, but your position almost amounts to an a priori claim that it is necessarily false.
I do think it is an open question. I’m quite prepared to accept that souls and consciousness by some sort of lock and key system can only attach to certain types of substrates. In my opinion, science and logic can’t quite get us there yet, but I’m curious whether someone with deep access to those truths has some hints to drop.
I want to know the answer(s) because the claim of consciousness is go to be coming fast, and I don’t have an answer.
