Although such a question deserves more attention, I would say that my current *feeling* is that "relative self-measure" cannot decrease with "time". But we must be carefull with the notion of "time" involved here. By "time" I mean something like the number of steps in the execution (real, virtual or just arithmetical) of a universal dovetailing algorithm. It is not physical time. Physical space-time is a higher order first-personal subjective construction. Relations between "DU-Time" and "Physical-(space)-time" exists. There are order preserving map between the branches of Physical-(local)-time and DU-time, but it is difficult to say more than that. And even that is more complex if we take into account the fusing phenomenon (cf George Levy's remark in preceeding posts of this thread).

A measure is needed for explaining the *normality* of experiences, and eventually deriving physics from comp, and showing the consistency of comp with empirical facts. I would not be immortal only if all branches in which some of "my" computationnal state has belong are finite. If just only one such branch remains, I will be there (for the best or the worst).

You argument would only work if the total number of >possible events remains constant, or diminishes with time. Exactly, would I say. To sum up: the immortality question is not linked to the measure problem. Both with MWI and comp, we must solve the measure problem only to prove the consistency of either MWI or Comp with the normal and deterministic empirical evidence. Bruno Bruno
