I am new to this kind of thoughts, so my questions could be naive. 
Still, I would appreciate if you could help me to understand such a 
statement.


In my understanding, people make models basically to become more 
competitive, in other words, to earn more money. From this viewpoint, 
the statement the model IS reality is a bit puzzling, as in this case 
the model brings actually nothing new. Say it is highly unlikely that it 
will help me to solve my personal problems (well, provided that I have 
free will whatever it means).


Some time ago, I have read

David Chalmers, The Matrix as Metaphysics
http://consc.net/papers/matrix.pdf

Let me make one citation

Importantly, nothing about this Metaphysical Hypothesis is skeptical. 
The Metaphysical Hypothesis here tells us about the processes underlying 
our ordinary reality, but it does not entail that this reality does not 
exist. We still have bodies, and there are still chairs and tables: it’s 
just that their fundamental nature is a bit different from what we may 
have thought. In this manner, the Metaphysical Hypothesis is analogous 
to a physical hypothesis, such as one involving quantum mechanics. Both 
the physical hypothesis and the Metaphysical Hypothesis tell us about 
the processes underlying chairs. They do not entail that there are no 
chairs. Rather, they tell us what chairs are really like.


Along this lines, I would paraphrase that TOE is just Metaphysics. Do 
you agree with this, or you mean something else?

The model is reality is something I'm following from the ultimate

Things get confusing also if, like Brian, (but also logicians in some

Well, that is what I explained to Chalmers in my (public, poster)  
presentation (on UDA) at the second meeting of the ASSC (association  
for the scientific study of consciousness) in 2000 (I think).


But this is true only locally. I cannot distinguish a virtual body,  
from a brain in a vat or from my real body, but with enough time I  
can find the difference, in principle. The deep point is that it does  
make a global difference. If the computationalist hypothesis is true,  
the laws of physics are non computational and have to be derived from  
the laws of numbers, and we can make a comparison. Chalmers, like  
most, still misses the first person indeterminacy, which make the  
matrix-and-only-matrix consequence of comp testable.
Chalmers told me that after a WM duplication the first person is in  
both cities, which is correct *from a third person point of view on  
the first persons, but not from the first person points of view  
themselves, and that is the crucial point to understand that the laws  
of physics have to be secondary with respect to the laws of mind  
(computer science/mathematical logic/machine's theology).


Also, the expression superstring are made of numbers is unclear. If  
computationalism is correct the expression made of has no sense.  
Things are not made of something, they are dreamed by (infinities) of  
computation. The physical worlds becomes the border of the matrix,  
that is a first person plural reality, a partially sharable dream.


Those points are not simple, and that is why I propose a step by step  
reasoning. If computationalism is correct, then the laws of physics  
are generated in a very specific way, which makes the computationalist  
hypothesis testable, and already retrospectively tested.


And by taking Gödel into account (and thus Löb, Solovay) not only the  
quanta get a purely mathematical origin, but the qualia too. Quanta  
appears indeed to be the sharable part of the qualia. Quanta are  
special qualia.
Superstrings are turing universal, so we can use it as a theory of  
everything-physical, if we want, but it is a treachery with respect to  
comp, and it makes you miss the theory of qualia, and the whole  
theology.


Remember that with comp, we can never know that we are awake. But we  
can always know that we are dreaming or sharing a dream. The  
experimental evidences (the quantum) are that we are indeed sharing a  
dream.

What makes a theory effective?
I'm going to be less precise given that my audience has changed in a
way I do not know.
Given a couple of assumptions, which are essentially that (1) reality
is independent of humans (which will imply that a model (in the logical
sense) can be a TOE as defined in this thread) and (2) a model every
model can be embedded within endows that model with a universality that
makes it a candidate for being reality. This is then a brief
description of reality, though I couldn't hope to give all the details
about reality.  I am also working on the hypothesis that a TOE can be
given in an finite/infinite presentation such as found in ZF with
axioms and axiom schemata.
Question: what is the theory with no assumptions?  I know that in
logic, the consequent closure of the empty set of statements is the set
of tautologies, which is not really what I'd call an effective theory.
But what about if we remove all assumptions?  Sounds like chaos to me.
This is connected to all this as I can explain.

In fact, I can prove (1) on the grounds that there is no largest
number.  It took me a while to find this argument.

 is the crucial point to understand that the laws of physics have to be
 secondary with respect to the laws of mind (computer science/mathematical
 logic/machine's theology).

It occurs to me that there could be an ambiguity here, as it is indeed
the case that, whereas there is only one first-person prior to the
duplication, there will be two afterwards.  Hence, as Chalmers says,
there will indeed be a first-person in both cities.  Both will be in a
position to lay claim to the same antecedent memories, but one would
expect their experience to diverge after duplication based on their
individual locations.  Does Chalmers rather claim some sort of ongoing
superimposition of experience after duplication? If so, on what basis?
 Or is it possible that there was indeed some ambiguity of expression
here?

The whole issue of where will I find myself after duplication is in
any case very curious.  Deciding who I am and where I am can only
be post-hoc on the basis of present experience in the context of
memory.  Were I in fact to make a prior bet on where I might find
myself to be post-duplication, presumably of the two first persons who
would eventuate, one would remember predicting correctly his
destination, and the other incorrectly. The question then of why I
might discover myself to be in the position of one of these first
persons and not the other then seems to collapse into the general form
why of all possibilities do I find myself to be occupying this
particular observer moment?.  Fortunately under ordinary
circumstances the issue of two identical three-persons being in a
position to lay claim to the same antecedent first-person memories
does not generally arise, but the problem seems to be the same even
without this.

 Thank you for your answers. We could say that the Universe is made
 of superstrings or we could say that the Universe is made of
 numbers. Chalmers shows that for a human being this basically makes
 no difference.

 Would that be because superstrings are made of numbers?

 This could serve as an explanation as well. Yet, I guess Chalmers wanted
 to show this in the general case.

 Well, that is what I explained to Chalmers in my (public, poster)
 presentation (on UDA) at the second meeting of the ASSC (association for the
 scientific study of consciousness) in 2000 (I think).

 But this is true only locally. I cannot distinguish a virtual body, from a
 brain in a vat or from my real body, but with enough time I can find the
 difference, in principle. The deep point is that it does make a global
 difference. If the computationalist hypothesis is true, the laws of physics
 are non computational and have to be derived from the laws of numbers, and
 we can make a comparison. Chalmers, like most, still misses the first person
 indeterminacy, which make the matrix-and-only-matrix consequence of comp
 testable.
 Chalmers told me that after a WM duplication the first person is in both
 cities, which is correct *from a third person point of view on the first
 persons, but not from the first person points of view themselves, and that
 is the crucial point to understand that the laws of physics have to be
 secondary with respect to the laws of mind (computer science/mathematical
 logic/machine's theology).

 Also, the expression superstring are made of numbers is unclear. If
 computationalism is correct the expression made of has no sense. Things
 are not made of something, they are dreamed by (infinities) of computation.
 The physical worlds becomes the border of the matrix, that is a first
 person plural reality, a partially sharable dream.

 Those points are not simple, and that is why I propose a step by step
 reasoning. If computationalism is correct, then the laws of physics are
 generated in a very specific way, which makes the computationalist
 hypothesis testable, and already retrospectively tested.

 And by taking Gödel into account (and thus Löb, Solovay) not only the quanta
 get a purely mathematical origin, but the qualia too. Quanta appears indeed
 to be the sharable part of the qualia. Quanta are special qualia.
 Superstrings are turing universal, so we can use it as a theory of
 everything-physical, if we want, but it is a treachery with respect to comp,
 and it makes you miss the theory of qualia, and the whole theology.

 Remember that with comp, we can never know that we are awake. But we can
 always know that we are dreaming or sharing a dream. The experimental
 evidences (the

It's even worse (better?) than that. If I read Bruno correctly, he is saying 
that the mere fact that every morning when you wake up you believe you are the 
same I you were before you went to sleep is a contingent observation. It may 
be that one does not have to step into a teleportation device to be duplicated.
