I find some inconsistencies in your post: > qubitstring containing all of the possible information-states implied in > such a long bitstring,...< possible, of course, to OUR knowledge (imagination). Anthropomorph thinking about the MW.
> Let Ui be an "internal-time-ordered" set of information-states > s1,s2,...,s(now) comprising an observable universe.< How 'bout the Uis where 'time' has not evolved? Excluded? Observable by what means? We have a pretty narrow range in mind. Would you restrict the MWI to our cognitive inventory of 2004? Does that mean that the MW was "smaller" in 1000 (with the then epistemized contents of cognition)? >... must be informationally consistent (not law violating) in conjunction ...< what "law"? presumed omniscient? Just malicious remarks. I appreciate to try and to criticize. I have no better ones.

Eric mentioned lately the group-evolution, in which respect altruism (moral thinking?) is not out, but go 1 step higher - still within the earthly biosphere - and morality turns into "foodchain". Dine or dined. There is no "goal" only change. Survival is a result. Human groups can identify what is good for them. E.g. to eat animals and plants - fellow living creatures.
