One interesting question is, when deciding to CEV people, from which era to extract the people. Saying that all eras would result in the same CEV is equivalent to saying that there is a fundamental correlation between the course of history and coherence which has but one final telos. An unlikely hypothesis, due to all sorts of things from evolutionary drift - as opposed to convergence - to orthogonality in ethics, to reference class tennis.
So researching how to distribute the allocation of CEV among individuals and groups would be a fascinating area to delve into.
But if CEV doesn't give the same result when seeded with humans from any time period in history, I think that means it doesn't work, or else that human values aren't coherent enough for it to be worth trying.
Hmm, maybe one could try to test the CEV implementation by running it on historical human values and seeing whether it approaches modern human values (when not run all the way to convergence).
Well think about the world in which most of it turns out pretty similar, but some, say 2% to 20%, depends on historical circumstance (and where that is cast once CEVed), I think we may live in a world like that.
That seems wrong.
As a counterexample, consider a hypothetical morality development model where as history advances, human morality keeps accumulating invariants, in a largely unpredictable (chaotic) fashion. In that case modern morality would have more invariants than that of earlier generations. You could implement a CEV from any time period, but earlier time periods would lead to some consequences that by present standards are very bad, and would predictably remain very bad in the future; nevertheless, a present-humans CEV would still work just fine.
I don't know what you mean by invariants, or why you think they're good, but: If the natural development from this earlier time period, unconstrained by CEV, did better than CEV from that time period would have, that means CEV is worse than doing nothing at all.
I used "invariant" here to mean "moral claim that will hold for all successor moralities".
A vastly simplified example: at t=0, morality is completely undefined. At t=1, people decide that death is bad, and lock this in indefinitely. At t=2, people decide that pleasure is good, and lock that in indefinitely. Etc.
An agent operating in a society that develops morality like that, looking back, would want to have all the accidents that lead to current morality to be maintained, but looking forward may not particularly care about how the remaining free choices come out. CEV in that kind of environment can work just fine, and someone implementing it in that situation would want to target it specifically at people from their own time period.
Or else, the humans values we care about are, say, ours (taken as broadly as possible, but not broader than that).
