"Enslave" is the wrong question, it implies the AI is being forced to act against its own desires.

That might happen if the AI has an off switch, knows this, and knows that we'll use that if it goes out of line, and wants to live.

But it isn't necessary.

The point is to construct it to want what we want, in the sense of sharing our values rather than envy, and then there's no conflict in the first place.

We just don't know how to even properly specify what we want.

Every attempt so far to specify what it means to be good has edge cases and loopholes — we don't even all agree on "don't kill" (war, death penalty, suicide assisted or otherwise, abortion, pollution that carries a statistically significant increase in mortality rates where no single death can be definitively proven to have been caused but overall many must have been, meat).
