I don't see the theory. What do you ask us to agree on, if only for  
the sake of the argument.
In the conclusion I don't understand the last sentence, which seems to  
me a proposition for abandoning theorizing in that field.

No, comp is a "theology" in which you believe that you can survive a  
concrete artificial brain/body transplants.
comp does not attempt this, it presupposes a level where it can be  
done. Among the first consequences appears the fact that such an  
attempt provably necessitates an act of faith.

Being successful here means only being able to explain (physical)  
observations. It is already successful in explaining the existence of  
sensations, and in situating quanta with respect to qualia.

Not at all, the comp theory, thanks to its Church Thesis part, and  
some mathematical logic, is particularly cautious in distinguishing  
the representation and the represented, and what will and will not  
depend on the choice of representations. By definition of comp we bet  
that there is a digital representation correct with respect to the  
most probable local universal number, or computation, but the comp  
theory, which is just computer science/number theory/mathematical  
logic will still take the many nuances into account.
For example: it is a theorem, not depending of the choice of any  
representation that all universal machines have to have a local  
representation to develop a third person notion.

Comp explains, or if you prefer, the Löbian machine can already  
explains, about simpler Löbian machines, why those simpler machine  
cannot represent their notions of truth and consciousness.  
Consciousness of machine M is not representable by machine M.
Comp provides a theory of consciousness, and this theory prevents us  
to represent our consciousness, except by betting on a sufficiently  
low level description and making an act of faith. A Löbian machine, I  
recall, is a universal machine which can prove (in technical weak  
sense) that she is universal. Most known Löbian machine are Peano  
Arithmetic and Zermelo Frankel Set Theory.

It is a theorem in arithmetic. It is a reason, in the sense that if  
you agree with some axioms of arithmetic, you can agree that those  
universal numbers exist, and contemplate a sequence of unexpected  
facts about them.

OK. No problem.

Hmm... I refer often to another result by Gödel, or similar discovered  
by Blum and others in computer science, that universal machine/number  
are infinity accelerable, and that lobian machine can shorten  
arbitrarily the length of infinities of theorems. Consciousness can be  
related by the inference of self-consistency, and it makes the machine  
able to add that consistency as new belief leading to a new machine  
provably more powerful, in its communicating or proving abilities, in  
the length or speed of proofs, and the same occur for its anticipating  
abilities, by a theorem of Royer.
Consciousness has probably developed with the relatively self-moving  
entities for letting them anticipate their neighborhoods more and more  
quickly. Comp explain both the role of consciousness and the reason  
why we cannot really defined it or capture the notion in any formal  
theory. Consciousness escapes representation, but feed on  
representations.

Assuming comp:
 From the third person sharable ontology you are right. First the  
numbers, then consciousness.
 From the first person point of view it is the contrary. First  
consciousness, then the numbers.
Both view, although contradictories, fit well with what a Löbian  
machine can already explain about itself.
(and fit well with Plotinus amanation/conversion transform

Machines/numbers cannot represent conscious experiences. They may live  
them, assuming comp.
They can represent piece of computation, but, those are not  
computation, they are representation of computation. No consciousness  
there. It is a key point to get UDA-8 (the movie graph, MGA).

?

It explains why machine can feel consciousness uncaused, like if they  
could remember in a first person way their belongness to arithmetic.  
Lobian machine can explain a "strangely similar" for simpler or  
actually any "definably correct by definition" Löbian machine. They  
can study themselves and explore their ignorance space.

I think this is what comp explain the best, thanks to the (rather  
incredible) discovery of the universal machine(s), and then by the  
work of Gödel, Löb, Solovay, for those universal machines which know  
their are universal.

I reduce the mind-body into a body problem.

What I say is just: oh look, if brain works like machine then we have  
to justify the appearance of physical laws by numbers only". This is  
UDA. And then I add, "oh look thanks to Gödel, Löb and Solovay we can  
already chat with the Lobian machine, and ask her opinion, and she can  
already explain some feature of physics, up to now confirmed by  
Quantum Mechanics.

Of course. Without theory (axioms) we cannot explain anything. But  
here the unexplained laws are just succession, addition, and  
multiplication. Without them or equivalent, we just cannot get them.

Any one believing that the concept of prime number makes sense,  
already believe in the theory. With comp, we can say that the theory  
of everything is already taught in high school, although not presented  
in that way, of course.

Comp forces us to (re)define physics as what is first person  
observable by ALL universal machine.
Physics loses its status of fundamental science, but is elevated as  
sharable laws of arithmetic ("seen from inside").
All the rest is contingent geographies.

They are uncaused "physically", but comp explains their logic- 
arithmetical origin, which is beyond time and space. Indeed time and  
space appears as inside first person psycho-theo-bio-logical category  
(a place where people can easily fight on voacabularies).
Consciousness is a mathematical phenomenon, a fixed point of self- 
doubting, an elementary belief in a reality if not the reality of the  
doubter.

Comp can make the conscious experience much more fundamental than the  
Aristotelian materialist usually think, yet consciousness is  
arithmetically "caused". It is an attribute of universal machine (in  
an even weaker sense than usual) related to their ideal self- 
consistency. It generates the belief in a reality, and the infinities  
of corrections which ensue.

Together with succession, addition and multiplication. In classical  
logic.

I don't think so at all. On the contrary, I even distinguish a  
computation and a representation of a computation, like I distinguish  
numbers and their relation with representations of numbers and  
representations of their relations. It is where mathematical logicians  
have an advantage, because such distinction is the key to comprehend  
most results in logic.
I know some have still problem with this in step 7 and 8, and that's  
why I propose a few math and logic.

I am afraid you underestimate mathematical logic. I would defined it  
here as the science of the relation between realities and their  
possible representations. Comp makes possible to, exploit this to put  
many light on the hard problem of consciousness. It explains there is  
a an unbridgeable personal third person gap, and how the first person  
can bridge it, yet.

I did not see the relation with consciousness. Physicsts, thanks to  
Everett and decoherence explains rather well the disappearance of the  
observable white rabbits, and this in a elegant way (phases  
randomization of waves of coherent interactions), this may explain why  
apparently we live in a quantum universal machine. My point is just  
that if you "say yes to the digital medication", then we have to  
justify that quantum universal machine from a sum on all classical  
computations.

Bit from qubit, is already understood,
I say comp gives an inverse, Qubit from bit, and that its main  
usefulness is that the inverse is enriched by its distinction between  
the sharable quanta and its incommunicable qualia extension. This is  
AUDA where the modalities are given by two mathematical theories of  
self-reference G and G*.

Assuming comp you can no more invoke quantum fluctuations, you have to  
derive them from universal specification. That works not too bad.

I don't like the idea to consider matter as fundamental, 'cause I want  
an explanation there.
I don't like the idea to put consciousness as fundamental, ' cause I  
want an explanation, there too.

I like numbers and their relations as fundamental, because many  
persons can share them, and tshare heir beliefs on them, and yet  
numbers and their relation have been discovered to lead to  
uncomputable richness. Besides, betting on comp makes me bet that I  
am , well not really one of them, but (one of them) multiplied by  
infinities.

Comp invites to study theoretical computer science.

And computer can already shows us the infinite complex border of a  
simple universal thing, like an iterated enlargement of the Mandelbrot  
Set:
