It’s great that you’re asking these questions but it’s clear that you haven’t done much research on the subject. If you’re genuinely interested in contributing to this field, I’d recommend checking out Stuart Russel’s book Human Compatible. It gives a pretty good overview of where we currently stand on this problem (sans developments in NLP over the past year or two) and gives a good sense of the problems we have yet to solve.
This is worth reading: https://www.amazon.com/Human-Compatible-Artificial-Intelligence-Problem-ebook/dp/B07N5J5FTS
I especially like Stuart's perspective on personalization and ethics.
