@ eli: nice series on lob's theorem, but I still don't think you've added any credibility to claims like "I favor the human one because it is h-right". You can do your best to record exactly what h-right is, and think carefully about convergence (or lack of) under self modification, but I think you'd do a lot better to just state "human values" as a preference, and be an out-of-the-closet-relativist.
