Both neoreactionaries and other people want a functional society, they just disagree on how to get it; both transhumanists and religious people want to live forever, they just disagree about whether life extension or preying to get into the best afterlife is the best way to go about it. Perhaps they have the same terminal goals? OTOH if religious people have 'faith' as a terminal value and atheists do not, then yes, this may be more of a problem. If people have 'other people follow my values' as a terminal value, this could be a very large problem.

I think that one of the problem with CEV is that we still have to say who's values we want to extrapolate, and it almost defines the outcome. For example CEV of values of C. elegance is not equal to human values. The main problem here is how we defined to be human. Here are most value groups differ. Will we include unborn children? Neanderthals? I mean that different value system have different definition of human beings, and "human CEV" is different for green party member who include all animals in "humans", and to neo-something who may exclude some people from definition of humans. So AI could correctly calculate CEV but to the wrong group.
