Because I think that MWI does not eliminate subjectivism. But,
perhaps, an Everettista may assume the existence of a universal
consciousness, to avoid the fact that different observers see
different components, in the "same" (if this has a meaning) experiment.
I also think (well J. Bell wrote this) that MWI presupposes (branching)
a time asymmetry, a time arrow which is not existent in QM (without
the measurement or the collapse). But I also think that it is exactly
this asymmetry, this irreversibility which prevents communications
or interferences between different "worlds".

No, I'll read it. Thanks.

Well, Peres in his book (page 374) wrote a chapter named "Everett's
interpretation and other bizarre theories". His point is that MWI "merely
replace the arbitrariness of the collapse postulate by that of the
no-communication hypothesis".
