CEV is supposed to refer to the values of current humans. However, this does not necessarily imply that an FAI would prevent the creation of non-human entities. I'd expect that many humans (including me) would assign some value to the existence of interesting entities with somewhat different (though not drastically different) values than ours, and the satisfaction of those values. Thus a CEV would likely assign some value to the preferences of a possible human successor species by proxy through our values.

An interesting question, is the CEV dynamic? As we spent decades or millennia in the walled gardens built for us by the FAI would the FAI be allowed to drift its own values through some dynamic process of checking with the humans within its walls to see how its values might be drifting? I had been under the impression that it would not, but that might have been my own mistake.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
