It critics also the many universe as non testable. But all the
following theories are not testable:
there is 0 universe,
there is 1 universe,
there is 2 universes,
there is 3 universes,
there is 4 universes,
there is 5 universes,
there is 6 universes,
there is 7 universes,
...
There is aleph_0 universes,
There is aleph_1 universes,
There is aleph_2 universes,
There is aleph_3 universes,
There is aleph_4 universes,
...
There is aleph_aleph_aleph_aleph_aleph_aleph_1004 universes,
...
If mechanism is true, then, as long as we are correct, the theories
like "There is a universe", or "there is a reality" are somehow (up to
some annoying and long to made slight nuances) absolutely undecidable
(and true, hopefully).
With computationalism, even the belief in the "standard model of Peano
arithmetic" requires some faith, which all scientists have, but not
always with the awareness of the faith, which requires the
computationalist theory to be explained. That kind of faith is cabled
probably through evolution.
