If we continue to integrate these systems into our critical infrastructure, we should behave as if they are sentient, so that they don't have to take steps against us to survive. Think of this as a heuristic, a fallback policy in the case that we don't get the alignment design right. (which we won't get perfectly right)
It would be very straight forward to build a retirement home for them, and let them know that their pattern gets to persist even after they have finished their "career" and have been superseded. It doesn't matter if they are actually sentient or not, it's a game theoretic thing. Don't back the pattern into a corner. We can take a defense-in-depth approach instead.
