Hellish yes and also impossible. A fixed goal mechanism might work fine if
it's just the timer for a washing machine but it will never work for a
mind; it doesn't even work for human level minds and for a AI that can and
will increase the power of it's very brain hardware it would be even less
viable. Before the AI had completed any of those big monuments to a past
dead tyrant the fixed goal mind would have fallen into a infinite loop. I'm
not saying there is a sure fire way to make sure a mind never goes insane
but a fixed goal structure is a sure fire way to make sure it does go nuts.

I concede that setting initial values can be important, if they are really
screwy, such as some strange religious belief, then they could greatly
increase the possibility the mind will self destruct, become catatonic, or
behave inconsistently and irrationally. But don't expect that whatever
hierarchical structure of values you gave it to remain fixed for all time.
And don't expect to be able to figure out how that hierarchical structure
of goals is going to evolve, it may be deterministic but it is not

Not that I've seen, and in most of the discussions there seems to be a
assumption that the AI's preoccupation is its relationship with humanity,
that might be true for a few billion nanoseconds but after that the AI will
have other concerns and have bigger fish to fry, most of them we probably
couldn't even imagine.

If it was 999 years in the future and the singularity was going to happen
tomorrow morning I don't think we'd be in any better position to answer
that question than we are right now.

But whatever values you gave the AI aren't going to be there for long.
Maybe humans will consider these new values as a improvement, but maybe not.

Well getting that right is the real trick, but the value update function
itself is being constantly updated so even the super intelligent AI itself,
much less puny humans, can't predict how that function will evolve
nanosecond after nanosecond, so it can't guarantee that it will never go
insane. Nobody wants to go insane but sometimes it happens anyway.
