Yes. Although it makes sense in QM only because QM justifies that some
possibility have more weight than others.
Now a universal turing machine (in the mathematical sense) cannot
distinguish ersatz linguistic worlds (cf David Lewis) from "real" one,
and this asks already for a "MWI" interpretation of arithmetic.
It less clear that some world will be less weighted (and that is what
we call the hunting of white rabbits).
