Well, perhaps the sample consisting of "Physicists Michele Simionato
knows" has *some* merit <wink>, but the single serious survey of
"great and good" Physicists' opinions I have read about (sorry, can't
give reference... but I think it must have been either in one of those
flaky books by Frank Tipler, or in Deutsch's "The Fabric of Reality"
that I read about it) revealed that a large majority believed
(essentially -- obviously there are subtleties) in the MWI. Not sure
when that was carried out either, but it was back when Feynman was
still alive.

Perhaps, but that has no relevance to the question of the reality of
multiple universes, of course.

Precisely, and IMHO (as well as, if you want argument from authority,
rather cleverer folks, like Deutsch), it's *YOU* that's confused about
that distinction! This is a hugely important point, so I'm glad it's
that point that you picked out of the detail in this thread. Science
is about reality, not prediction, and the MWI is a theory, not an
interpretation.
Skipping back a bit:
> 4. there are much more interesting things to study.
Certainly people like Deutsch do get quite pissed off that they have
to spend time defending what should be a done deal by now, taking time
away from more productive and interesting Physics work. In fact, he
loudly complains about it in his book, and not just wrt MWI: the same
problem occurs in evolutionary theory, for example (and there is
actually an interesting connection between MWI and natural selection).

But that was *your* joke, Michele! It's merely your *interpretation*
of the data that I really exist -- in *reality*, I'm just a figment of
your imagination <wink>.
(But I guess it's okay to laugh at your own jokes if you're the
solipsist :-)

Already has! :-)
