The goal consists in explaining the no cloning theorem without
assuming physics.
I read your recent paper where you discuss how comp circumvents that
theorem.
But do not understand your argument.
It is equivalent IMO to comp circumventing the uncertainty principle.
Could you discuss this?
The problem is that to explain this to you, I need to know how far you
go in the UD-Argument.
If you have gone through the 8 steps, you should know that all we need
to assume is a (classical, quantum, whatever) universal formalism/
theory, and I use the numbers+add+mult to fix the thing.
Then you know that in that universal formalism, notably in the
arithmetical reality, we can prove the existence of an infinity of
computations (or of finite piece of computations: the first person
will not see the difference) going through your state, defined by some
substitution level. Below the level, and thus in the "apparent
matter", there will be an infinity of computations needed to describe
exactly that matter (the global FPI domain in arithmetic). This makes
a priori the apparent primitive matter non-clonable. The primitive
matter is literally a statistical sum on infinity of histories/
computations, and you need the entire running of the UD to define it
(to get the global FPI). It is not something a priori duplicable.
So, indeterminacy, non-locality, and non-cloning, are, qualitatively,
consequence of the comp hypothesis. QM confirms this (which *proves*
nothing, to be sure).
If our (sharable) level of substitution is exactly the quantum level
(that is for example the position and impulsion of our particles at
the Heisenberg uncertainty level, or just above) then quantum
mechanics will be exactly derivable from comp. If our substitution
level is below the Heisenberg uncertainty level, (we would have a
quantum brain/computer) then things are more complex. As the UD
emulates also all quantum computations, the reversal physics/
arithmetic is still obtained, but QM could no more be the fundamental
theory in physics, and might appear as an approximation of an unknown
theory (something like a non-linear QM). I doubt this from the
evidences both from introspection, biology and physics. If our subst
level is far above the quantum level, then QM can still be derivable
from arithmetic, but some constants can be geographical (and thus
variable in the whole of the physical reality).
We can come back on this. Better to be completely convinced by the UDA
before, as it gives the frame in which address your difficult question.

Yes, things progress. Nice to hear of you George, best,
Of course, we cannot test the first person experience of the rat.
Even if the rat can talk, that would prove almost nothing, but the
human will say "yes" to the doctor anyway, and without thinking to
much on the theoretical consequences of the possible survival.
To stop comp to be *applied*, we should have made glasses illegal
long ago ... Then we can argue that molecular biology confirms the
use of comp by biological system all the time.
