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:

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.
