No, unfortunately, much more complicated and much more fuzzy. Unfortunately it's a Pascalian thing. Basically, if post-singularity (or pre-singularity if I got insanely lucky for some reason - in which case this point becomes a lot more feasible) I get access to infinite computing power, it doesn't matter how much of my measure gets through, because I'll be able to take over any 'branches' I could have been able to reach with my measure otherwise. This relies on some horribly twisted ideas in cosmology / game theory / decision theory that will, once again, not fit in the margin. Outside view, it's over a 99% chance these ideas totally wrong, or 'not even wrong'.
