The only hope is to instill values that make the desired behavior the outcome of some deeply rooted ethical framework.
We are talking about creating regulation today.
Its absurd to believe we're currently at the level of dependency & intelligence that no other defense will be effective.
Again, i'm much more worried about your perspective of the future has you believe its inevitable that we will build the level of dependency and hand over all control, that the only line of defense is the vague ethics framework we'd be installing right now.
I'd go so far as saying that unlike these hypotheticals, we have historic examples of groups trying to stop conflict by converting/merging some religion or other cultural practices; and while it helps, the rate at which conflicts persists is unacceptably high if you believe failure is existential.
Lets say we figure all that out and we pick a core universal morality. If they are smarter than us than how would we know the alignment worked? We would be unable to detect their lies and schemes.
But I find it much more worrying that you believe internal constraints and training an ethical framework into these models is a valid form of defense against the damage they can and will do.
This sounds like homeopathy on gunpowder to prevent the bullets from hitting children.
