MWI realists? How can Many Worlds be Realistic? Realism means things
must not only exist but exist in one and only one definite state
even when they are not being observed; so whatever else it may be
Many Worlds is NOT realistic. And we know for a experimental fact
that Bell's inequality is violated, therefore simple algebra forces
us to conclude that at least one of the following things must be
wrong, perhaps all 3:
1) Realism
2) Superdeterminism
3) Locality
Although I can't prove it's wrong I find it almost impossible to
believe Superdeterminism is true, but Locality might be.

Many Worlds is ANTIMATERIALIST -
https://en.wikipedia.org/wiki/Antimaterialism - to the core:
There is a quantum chip in a computer that randomly produces a 0 or 1.
The computer is hooked to a small guillotine with an electrical switch
hooked to the computer. Under the blade is an apple. If a 0 is
produced ("world" A) , no signal is sent, but if 1 is produced, then
the blade chops the apple into 2 pieces ("world" B).
How much apple is there in A and B combined?
If enough for two apples, the how did the extra matter come from?
If there is the same amount of matter in A and B combined as A and A
alone, then is the 2 halves of the apple in B lying on the table also
one whole apple too?
Or you can interpret the alternate worlds in the same way as in block
time. So, if besides the present moment, the past and the future are
equally real (as suggested by relativity) then all the matter in the
universe that exists at the present moment also exist in the parallel
yesterday and tomorrow world. So, the best way to interpret the
multiverse is to simply assume that all possible time snaps of universes
exist as timeless entities. In classical physics, there is a one
parameter family of parallel worlds with the same information content.
In QM the information present in a world cannot in general be retrieved
from another world, in general one needs to consider superpositions of
different worlds.
