1. It's the simplest theory: "MWI" is just the
Schrodinger equation, nothing else. (it doesn't say
Schrodinger's equation only applies sometimes, or only
at certain scales)
2. It explains more while assuming less (it explains
the appearance of collapse, without having to assume
it, thus is preferred by Occam's razor)
3. Like every other successful physical theory, it is
linear, reversible (time-symmetric), continuous,
deterministic and does not require faster than light
influences nor retrocausalities
4. Unlike single-universe or epistemic
interpretations, "WF is real" with MWI is the only way
we know how to explain the functioning of quantum
computers (now up to 51 qubits)
5. Unlike copenhagen-type theories, it attributes no
special physical abilities to observers or measurement
devices
6. Most of all, theories of everything that assume a
reality containing all possible observers and
observations lead directly to laws/postulates of
quantum mechanics (see Russell Standish's Theory of
Nothing
<http://www.hpcoders.com.au/theory-of-nothing.pdf>,
Chapter 7 and Appendix D).
Given #6, we should revise our view. It is not MWI and
QM that should convince us of many worlds, but rather
the assumption of many worlds (an infinite and
infinitely varied reality) that gives us, and
*/explains /*all the weirdness of QM. This should
overwhelmingly convince us of MWI-type everything
theories over any single-universe interpretation of
quantum mechanics, which is not only absurd, but
completely devoid of explanation. With the assumption
of a large reality, QM is made explainable and
understandable: as a theory of observation within an
infinite reality.

You forgot #7. It asserts multiple, even infinite copies
of an observer, replete with memories, are created when an
observer does a simple quantum experiment. So IMO the
alleged "cure" is immensely worse than the disease, CI,
that is, just plain idiotic. AG *
There are many atoms, many planets, many solar systems, many
galaxies, many Hubble volumes, and it is believed many
universes. On what basis are you so certain there aren't many
histories? (That is, other states in the wave function that
are predicted to be there by our well established scientific
theories, but which the theory explains we cannot see or
interact with except in very limited controlled manners)?
If you find MWI distasteful you might prefer to think of it as
the many-minds interpretation as described by Heinz-Dieter
Zeh, or the "zero-universe interpretation" as explained by Ron
Garrett: https://www.youtube.com/watch?v=dEaecUuEqfc

I think you are hung up on the "creation", I think it is
conceptually easier to grasp under the understanding that it
is all already there. If you look at the homepage of Wei Dai
(who founded this e-mailing list
<http://www.weidai.com/everything.html> 20 years ago) he
outlines what he calls "a very simple interpretation of
quantum mechanics
<http://www.weidai.com/qm-interpretation.txt>" which is
basically this: all the states are already there.
*Sounds like Super-Determinism proposed by t'Hooft, and referenced
yesterday by Brent, which proposes the universe knows beforehand
what kind of experiment Joe the Plumber will perform. Too
ridiculous for my tastes, and of course untestable. IMO, one of
the "achievements" of quantum theory is to make otherwise
intelligent persons totally gullible in what they believe as
plausible. AG*
I agree with you about super derterminism being too ridiculous to
believe. But super derterminism is a different animal from "block
time". Super derterminism is the idea that the universe conspires
against all experimenters and knows what they will measure before they
measure it, and chooses values they will measure to make things work
out. It's reminiscent of Descartes evil demon. It requires an evil God.
You've anthropomorphized the universe. The universe doesn't conspire or
do anything, it just is. Experimenters are just physical systems (as
they are in MWI) so it's not strange that in a deterministic theory (and
MWI claims to be deterministic) their actions should also be determined.
But block time, the idea that the future points in time are as real as
past and present points doesn't need super derterminism. It's actually
implied by special relativity.
Block time plus MWI means universes aren't created, they're all
already there. We just are able to differentiate which one(s) we end
up in when we measure something.
What color is your toothbrush? Before the memory enters your
consciousness you're in a super position of possibilities.
That's over extending a metaphor. It's putting consciousness back into
collapsing wave functions.
Brent
Once you remember now you've isolated yourself to those universes
where it has the particular color you remembered. That's all it is.
