One thing we *do* know for sure is that Harry Potter universes --
*literal* HP universes -- are computable, since the special effects
in the Harry Potter movies were computer generated!
Therefore the problem with everythingism is that it predicts *too much*
weirdness. (And, as I am forever pointing out,
materialism-contingency-empiricism [*] doesn't exclude quantum
fuzziness or many
worlds, providing there are contingent facts about how much fuzziness
and how many worlds).
[*] my term for the non-everythingist philosophy.
