I will get this time, but here are my objections to the first step
and the stipulated assumptions of comp. I understand that the point
is to accept the given definition of comp, and in that respect, I
have no reason to doubt that Bruno has accomplished what he sets
out to as far as making a good theory within comp, and if he has
not, I wouldn't be qualified to comment on it anyhow. From my
perspective however, this is all beside the point, since the only
point that matters is the actual truth of what consciousness
actually is, and what is it's actual relation to physics and
information. Given the fragile and precious nature of our own
survival, I think that implications for teleportation and AI
simulation/personhood which are derived from pure theory rather
than thorough consideration of realism would be reckless to say the
Step one talks about teleportation in terms of being reconstructed
with ambient organic materials. If comp were true though, no
organic materials or reconstructions would be necessary. The
scanning into a universal machine would be sufficient.
That is step 6.
I haven't even gotten to step 2 yet. I'm reading "In the figure the
teleported individual is represented by a black box. Its
represented by a white box appearing at the left of the arrow" from 1.
Taking this to the China Brain level, the universal machine could
be a trillion people with notebooks, pencils, paper, and erasers,
talking to each other over cell phones. This activity would have to
collectively result in the teleported person now being conjured as
if by incantation as a consequence of...what? The writing and
erasing on paper? The calling and speaking on cell phones? Where
does the experience of the now disembodied person come in?
As you illustrate here, plausibly not on the physical means used by
the brain. Step 8 shows that indeed the physical has nothing to do
with consciousness, except as a content of consciousness. Keeping
comp here, we associate consciousness with the logical abstract
So the person's consciousness arises spontaneously through the
overall effort-ness behind the writing, erasing, and calling, or
does it gradually constellate from lesser fragments of disconnected
Consciousness does not arise. It is not in space, nor in time. Its
local content, obtained by differentiation, internally can refer to
time and space, but that's particular content of an atemporal
consciousness. I would say (no need of this in UDA).
Step one talks about annihilation as well, but it is not clear what
role this actually plays in the process, except to make it seem
more like teleportation and less like what it actually would be,
which is duplication. If I scan an original document and email the
scan, I have sent a duplicate, not teleported the original.
Right. Classical teleportation = duplication + annihilation of the
original. That's step 5, precisely.
You understand the reasoning very well, but we know that the problem
for you is in the assumption.
Yes, the assumption seems to presume physicality to disprove
At some place, yes. In a reductio ad absurdum.
and presume consciousness to explain consciousness.
Yes. Like we presume (at some metalevel) anything we want to explain
(from some other realm). It is not a lott, but science works that way.
We don't know the public truth. We can only make clear our hypothesis
and reason, and propose tests.
Computation seems to have nothing to do with either one of them in
comp other than the fact of the plasticity and aloofness of comp can
be seen as a sign that it is neither mind nor matter. It still
doesn't answer the question of why have appearances of mind or
matter at all?
Comp is used to formulate the problem in math. Then we can see the
general shape of the solution, which is a reduction of physics into
arithmetic, with the advantage that we get a clear explanation of the
difference of qualia and quanta. And we can test the quanta.
If there is a reason, then that reason is the nature of the cosmos,
not the filing and organizing system that indexes it's activities.
Why? A program or piece of information is not nothing. It asks
works, can be paid for, can be precious and rare, etc.
I have problems with all three of the comp assumptions:
yes, doctor: This is really the sleight of hand that props up the
entire thought experiment. If you agree that you are nothing but
your brain function and that your brain function can be replaced by
the functioning of non-brain devices, then you have already agreed
that human individuality is a universal commodity.
It can't ask for anything by itself though.
We are the ones to whom the significance relates.
Actually God told me yesterday that we are wrong on this. Only the
jumping spider can do that.
Information is nothing but an experience that can be remembered and
transmitted to other experiencers through formation.
Church thesis: Views computation in isolation, irrespective of
resources, supervenience on object-formed computing elements, etc.
This is a theoretical theory of computation, completely divorced
from realism from the start. What is it that does the computing?
How and why does data enter or exit a computation?
It is a discovery by mathematicians.
And it is a valid discovery in the context of mathematical theory,
but it doesn't translate to the realism of subjectivity and physics.
Physics, or not physics are not among the hypothesis. More in the

We search the reason. You say "for no particular reason" without
providing a reason.
Arithmetical Realism: The idea that truth values are self
justifying independently of subjectivity or physics is literally a
shot in the dark. Like yes, doctor, this is really swallowing the
cow whole from the beginning and saying that the internal
consistency of arithmetic constitutes universal supremacy without
any real indication of that. Wouldn't computers tend to be self-
correcting by virtue of the pull toward arithmetic truth within
each logic circuit? Where do errors come from?
They come from the inadequacy between belief and truth.
Incompleteness makes this unavoidable at the root, and that is why
the logic of Bp & p is different from the logic of Bp, despite G*
proves Bp -> p. G does not prove it, so correct machine already
knows that they might be incorrect "soon enough".
Your last paragraph confirms you are still thinking of machines and
numbers in a pre-Godelian or pre-Löbian way, I think.
I admit that I have only a wisp of understanding about modal logic
and Gödelian-Löbianian ideas, but I feel like even this surface
understanding is enough to tell me that it is ultimately a red
This is self-defeating.
These concepts seem to just be about self-reference - maps of maps
with no territory. Great for simulating some aspects of thought,
because indeed, thinking has to do with copying copies and
intellectual grammar, but feeling doesn't.
The machine knows that, already. Feeling and first person notion have
no 3p representation at all. For logical reason, explainable with the
These are ways of mentioning how ideas are mentioned. In reality,
this sentence does not refer to itself. There are only characters,
or pixels, or optical phenomena here. The significance does not

This has already been commented. You confuse the 3p self-reference and
the 1p self-reference. I think.
