I agree with this but I prefer weighting things by computation power instead of physics cells (which may turn out to be somewhat equivalent). It's easy to justify this model by assuming that some percentage of the multiverse's computation power is spent simulating all universes in parallel. See Schmidhuber's paper on this.

Cool -- thanks! Yeah, my proposal is just about how to conceptualize the sample space, but it would be trivial to replace

count(stuff I observe) / count(all stuff)

with

measure(stuff I observe) / measure(all stuff)

for some non-constant measure function.
