I think Hal Finney and Wei Dai have defended something like this. But in the comp RSSA(**) realm, strictly speaking even the notion of "one" universe (even considered among other universes or in a multiverse à-la Deutsch) does not make sense unless the comp substitution level is *very* low. Stable appearances of local worlds emerge from *all* computations making all apparent (and thus sufficiently complex) world not "turing emulable". Recall that "I am a machine" entails "the apparent universe cannot be a machine" (= cannot be turing-emulable (cf UDA(***)). Bruno For the new people I recall the acronym: (*) ASSA = absolute self-sampling assumption (**) RSSA = relative self-sampling assumption The SSA idea is in the ASSA realm comes from Nick Bostrom, if I remember correctly.
