This is false. Even in Everettian QM there are only two possible
outcomes for each spin measurement: this leads to two distinct worlds
for each particle of the pair. Hence only 4 possible parallel
universes. Where do you get the idea that there are infinitely many
parallel universes? This is not part of Everettian QM, or any other
model of QM. But even if you can manufacture an infinity of
universes, you still have not shown how this removes the non-locality
inherent in the quantum formalism.
Bruno's ontology is all possible computations, so he's already assumed
(countably) infinite worlds. When there are only four or two outcomes
of an experiment it just means his worlds are divided into four or two
equivalent subsets.
That might very well be the case. But then that has absolutely nothing
to do with Everett or quantum mechanics. Bruno's long-held claim is that
Everett's many worlds obviate the need for non-locality. But he has
never been able to produce a coherent argument to this effect. It is
always this bullshit about an infinite number of worlds -- as if that
made any difference at all.
I think Bruno should really face up to the fact that his "comp" has not
produced any coherent quantum theory, so he should just stop making
unsubstantiated claims about what his theory does or does not say about
the facts of quantum mechanics. If Bruno wants to make claims about
Everettian QM, then he should confine himself to that well-defined
theory, and not keep obfuscating by referring to his own idiosyncratic
ideas.
