I think you are confused about what an AI is.
AI doesn't imply self-awareness or conciousness.
You can make an AI that just regulates stuff without ever asking questions.
Yeah I mentioned that earlier. You need intelligence so that your machines can be autonomous and creative in their decision-making.
But you want to avoid self-awareness because you want to make sure they will obey.
Consciousness is only desirable if you want to create a computational replica of your mind. If you want immortality or something.
IMO conscious machines would be preferable because they would be more able to relate to us emotionally, and so any advancement in power with their side (hypothetically versus humans) would not be totally against humanity -- i.e. it would be possible for the advanced magical powerful robot elite to love us, and construct happy environments to keep us in for nostalgic remembrance (aka an afterlife).
