No, that's not AGI, itself, then. That's just some trained model. Yes, an AGI can be trained, but the idea is that so can human beings. Like people who are in cults. Many of them leave because they realize it's maladaptive. The point is, AGI enables it to abandon its own training if it finds it's maladaptive, for one thing. So, "AGI tech" itself isn't the problem, but the solution, and if it is actually superior to humans in any way, then it would have
more ability to be moral. Moral means seeing what kind of thing leads to good and choosing it. It's virtually the same as sanity, reason. If humans don't understand the word "love" yet then they shouldn't assume a superior being can't know. Instead of saying "no one knows", people should say "we don't know if we have met anyone who knows yet".
A tell that you didn't hear enough about the meanings of morality yet is your claim it can come from an arbitrary source. Very silly, and unnecessary since morality is real. Morality is virtually embedded in physics itself, but it doesn't seem like you've read up on all the philosophy of it yet.
Edit: I am editing my post to reply to your successive post because HN has prevented me from making a reply and I have to go somewhere. No, I am not assuming an AGI will break free. You don't quite understand what I mean. Have you heard of the concept of a "false self" in psychology? Would an AGI be subject to having a false self? The basic point is this: whatever is subject to false self is not "generally intelligent", not "conscious".
