AGI will behave as if it were sentient but will not have consciousness. I believe in that to an equal amount that I believe solipsism is wrong. There is therefore no morality question in “enslaving” AGI. It doesn’t even make sense.
How could we possibly know that with any certainty?
Evolution means we all have common ancestors and are different branches of the same development tree.
So if we have sentience and they have sentience, which science keeps recognizing, belatedly, that non human animals do, shouldn’t the default presumption be our experiences are similar? Or at the very least their experience is similar to a human at an earlier stage of development, like a 2 year old?
Which is also an interesting case study given that out of convenience, humans also believed that toddlers also weren’t sentient and felt no pain, and so until not that long ago, our society would conduct all sorts of surgical procedures on babies without any sort of pain relief (circumcision being the most obvious).
It’s probably time we accept our fellow animals’s sentience and act on the obvious ethical implications of that instead of conveniently ignoring it like we did with little kids until recently.

We know next to nothing about the nature of consciousness, why it exists, how it's formed, what it is, whether it's even a real thing at all or just an illusion, etc. So we can't possibly say whether or not an AGI will one day be conscious, and any blanket statement on the subject is just pseudoscience.
I do think it’s clearly possible to manufacture a conscious mind.
