I was thinking specifically of Max Tegmark's MUH. He considers
minds to be "subsystems" of the maths - he doesn't say anything
about computations existing in arithmetic. So I think he probably
hasn't developed that aspect of the theory to the extent that you
have, and may not realise the full implications. Have you had any
communication with him? It could be interesting to combine your
ideas.
We have discussed on this list a long time ago. I was astonished
that he does not believe in the quantum immortality,
Interesting. And he is one who is well known for popularizing the
idea of proving MWI by putting a quantum gun to one's head. How did
he justify his disbelief in quantum immortality while at the same
time believe in MWI? What would he think the experimenter will
experience when he gets in the box with Schrodinger's cat?
Tegmark thinks he will survive, if the gun works sufficiently well. if
not he might degrade and eventually ... die. This makes no sense to
me. It is annoying, but we can degrade a lot, yet we can't die (with
just comp, or, ITSM, with just the quantum MWI). With comp, we can
expect jump, and "consciousness phase transition", though.

and is not aware of comp (and mathematical logic). There is a big
gap between physicists and logicians. The book by Pale Yourgrau on
Einstein and Gödel illustrates this very well. The book by Penrose,
which I find very courageous, but erroneous on the Gödel/mind/
machine relation, has considerably augment that gap. Physicists
tends to run away when hearing the word "Gödel" ... many logicians
runs away when they heard the word "reality", or even worst
"physical reality".

If the Mathematical Universe Hypothesis is correct, spacetime (and
everything else) is an emergent feature of maths, which makes it a
secondary feature of a nonphysical, Platonic object, though not
mind.
And if we are digitalizable machine, then the Mathematical Universe
hypothesis is correct for the ontology, and we need only elementary
arithmetic, and physics is a secondary feature, but it *is* a mind
fetaure, with the mind emerging from the computations (existing by
elementary arithmetic).
By allowing an observer to be a non-machine *of some kind*, you can
need richer mathematical theologies/physics, but that's not
entirely clear to me.
The mind itself cannot be entirely mathematical. At least, nor from
inside, where we are living (now), assuming we are machine.
So if we consider both the 3p and the 1p, the mathematical
hypothesis is only 99,9998% correct. The tail of the cow can't go
through the window!

I am shocked to find that so far I have not
found a scientist anywhere that understands
that spacetime, being just lawful behavior (laws)
is platonic (is mind). Perhaps they consider it to be quantum
gravity.
