If you estimate that our mechanist level of substitution is so low
that we have to emulate the internal complexity of the neutron, it
means that the substitution level is very low, but the UDA reasoning
would still go through.
Only if the complexity of the neutron behavior is both infinite (or
non Turing emulable) AND relevant for the computation on which your
mind relies "here and now" would the reasoning stop to go through.
To be sure, I really doubt that we have to take into account the
internal aspect of the particles which constitutes our flesh. But the
point is that to stop the working of the UD argument you have to put
infinities in both mind and flesh, and say "no" to the digitalist

6. By Church-Turing thesis, a Turing machine (computer) can process

that to say
the mind is emulable by a computer says very little about a mind, it
essentally says only that that the mind is a process. The analogy
is that a
computer can process information in any possible way given the
programming, just as a record player can produce any possible sound
the appropriate record. Saying the mind is emulable by a computer

It doesn't matter if the process is like parallel programs, networked

a whole bunch of computers running in parallel without any

Thanks for the weekend wishes.
I believe the Brain runs programs, in parallel, but are they the
Mind, and are they able to be run as Turing emulable programs with
impact to one's consciousness?

the Cantor-like diagonalization procedure does not lead outside the

psycholically that price is a relief: it prevents computer

programs, or something else.
Brains and other biological organs and organisms, run parallel
programs. But all digitalizable parallel programs can be made
equivalent with dovetailing on non parallel programs. The UD does
an infinity of programs in parallel, for example. So the brain
parallelism does not change anything unless the brain is not a
digitalizable physical process (but then we go outside the scope of
Digital Mechanism, the theory I am working in).
Theoretical Computer Science is, amazingly enough, something non
dimensional. This of course forces us to explain why dimensionality
seems so important in the physical sciences, or in the observable
sharable (first person plural) realities.
Don't hesitate to ask for precisions.

Yes. The UD is somehow given by the true sigma_1 arithmetical

many proofs. This can be derived from a well known result
that the computable functions are representable in Robinson
arithmetic, or you can use the beautiful work of Putnam, Juila
Robinson, Davis, and Matiyazevitch). This makes it Turing
and makes the UD emulated in Platonia (or in any model of Peano
Arithmetic, that is a tiny part of arithmetical truth).
