I can give sense to that. I cannot give 3-sense to the word 
"modern" though, it is a typical (plural) first person expression,
which add nothing to a "scientific" or "axiomatic"  or 3-defensible

So the Great Programmer is not even the UD. The UD, with Church Thesis,
wrote all programs and execute all programs. The problem consists in
explaining appearance of beliefs like "our universe" from possible
(consistent) inside point of views scattered in UD* (UD's work).

The UD is the shortest explanation then. Although a shallow one 
which only permits a (re)formulation of the mind body problem.
With comp the appearance of big bang and cosmos must be explained.
If you make the distinction between 1-person and 3-person you get
an "absolute" form of indeterminism (the self-duplication) making it
possible to define a measure on the consistent extensions, which,
I repeat are scattered in UD*.

You have still not explain to me how you predict your reasonably next
experience in the simple WM duplication. Nor, a fortiori, how the
1-person can take into account the delay of reconstitution
accessed by the UD (which is necessary to do if you want single out 
one program in UD* and one computation. With comp we must take all 
computations into consideration.

more explanations.

Good argument, corresponding to a new version of the old
dream argument. Good argument for comp, but nocturnal dream
recall us also that certainty of being awake relatively to a
neighborhood does not entails that neighborhood is our "true"
neighborhood. Remembering dreams (especially the common non lucid
one) can help to anticipate the possibility of inconsistency (<>[]f,
A theorem of G* which is not a theorem of G, although G
proves <>t -> <>[]f). I mean "<>[]f" is a typical true and anticipable
but non provable proposition by self-observing sound machines.
Both the thought experiences and their arithmetical
translations illustrates our necessary ignorance about which
sheaf of coherent computations we belong to.

Comp, without QM, entails strong form of non trivial 
indeterminacy and non-locality.

Look at http://www.escribe.com/science/theory/m2855
for a purely arithmetical interpretation of Bell original
inequality (cf [] = godel provability predicate,
<> = -[]-, p represent \Sigma_1 sentence (= UD accessible).
Is that inequality violated in the UTM mindscape? Open
question (although there are argument showing that it
would be quite astonishing that those inequalities are
not violated.

Before going into such technics it would help us if you told
us what is wrong with the comp 1-person indeterminism
in the simple self-duplication experiment.
We discuss that before, but I am still not sure to
be able to make sense of your critics.
