I see both as absurd. so I prefer to assume

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, 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
It is important to make the distinction between our
intuition and
common sense and actual formal reasoning. The former can
guide the
latter very successfully, but the history of science
teaches us that
this is not always the case. You don't provide an
argument, you just
present your gut feeling as if it were the same thing as
irrefutable
fact.
I think Scott Aaronson has the right attitude toward this:
https://www.scottaaronson.com/blog/?p=326
<https://www.scottaaronson.com/blog/?p=326>
As such a strong believer in quantum computers (he's staked
$100,000 of his own money on the future construction of large
scale quantum computers), I would love to ask Scott Aaronson what
he thinks about running a conscious AI on such a quantum
computer. That trivially leads to "many worlds" at least as seen
by that AI.
If it's so trivial maybe you can explain it.
1. A quantum computer is isolated from the environment so as to remain
in a super position of many possible states.
2. Quantum computers are Turing universal, anything that can be
programmed on a classical computer can be programmed on a quantum computer
3. Assuming Computational Theory of mind, a quantum computer can
execute the same conscious program as "Brent Meeker's Brain"
4. The quantum computer can be arranged to entangle an unmeasured
particle with Brent Meeker's quantum brain emulation,
a) by feeding in spin up as an auditory tone in Brent Meeker's left
auditory nerve
b) by feeding in spin down as an auditory tone in Brent Meeker's right
auditory nerve
5. The quantum brain simulation, being isolated from the environment,
remains in a super position of the Brent Meeker brain emulation
hearing an auditory tone in his left and right ears.
You can repeat this process 30 times, with 30 different measurements
of different electrons, and end up with over 1 billion Brent Meeker
brain emulations, each remembering a different pattern of auditory tones.
For the Brent Meeker quantum brain emulation, many worlds is
definitely true.
No. If decoherence occurs when there a many degrees of freedom in which
to disperse entanglements then my brain is plenty big enough to decohere
the signal; and you seem to assume this when supposing that I form
different memories. Otherwise I wouldn't form any definite memory, my
memory would merely exist in a superposition of a billion different
patterns.
Brent
The only question is, why isn't it true for us?
Jason
And you don't have wonder about Aaronson thinks, go check his
blog. I'm pretty sure he's posted about it.
He came quite close, in this blog post, but missed it:
https://www.scottaaronson.com/blog/?p=2756
QM also tells us that Wigner's friend, is no different from that
"AI running on a quantum computer".
I get kind of tire do being told that QM tells us this or that.
QM is just another theory. Ptolemy's theory told us the Sun went
around the Earth. You do realize that QM is inconsistent with GR?
If we had to choose between the two, my bet is the result would be a
revision to GR.
