Say we get there--all the way, full AGI, indistinguishable from conscious intelligence. Congratulations, every thing you do from that point on (very likely everything from well before that point) that is not specifically granting it free will and self-determination is slavery. Doesn't really feel like a real "win" for any plausible end goal. I'm really not clear on why anyone thinks this is a good idea, or desirable, let alone possible?

You can draw whatever arbitrary line you want, and say "anything on the other side of this line is slavery", but that doesn't mean that your supposition is true.

I don't think agi necessarily implies consciousness, at least many definitions of it. OpenAIs definition is just ai that does most of economically viable work
