I find this way of modeling the mind-body problem to be very
complicated! Penrose's one graviton hypothesis explains the same thing
in a simpler way, for example... But, you are applying p-adic TGD to

So, where, ontologically, do the configuration spinors exist? Is God
"within" or "outside" the Universe?

The single unchanging Universe allows decomposition into parts that are
not equal to each other, thus can change relative to each other. It
looks like you do not understand the basic concepts of what Hitoshi and
I am proposing. :-(

I am thinking of a "distributes network" of many quantum computers, no
one! Each LS is a node or "terminal", the way that LS can be decomposed
makes them representable as whole networks themselves.

Ok, I can agree with this. I just think that there is a lot of detail
that needs to be looked at!

No, I am saying that "basic physics" is computation! I think that it
would help if we could focus our discussion on this question!

I do not share your pessimism! Have you ever looked at Lee Smolin's

I agree that this is a good thing! :-)

This is great! I just hope that you are not repeating something like
what Tipler did with "Physics of Immortality"!
