In the ASSA(*) realm I can give sense to this. 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(***)).

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.
(***) UDA: see for example
