Why? All physical theories relate to particular measurements.

That's true. So, machines can handle symbols with unspecified meaning,...?

You have not given any physical law. Predicting that some quantum stuff is
going on is not "giving the physical laws".
The UDA may simply not work, if COMP is false. You can't use the hypothesis
that COMP is true to defend that it is refutable!
In order for it to refutable you have to make actual predictions.

No, I am not confusing "2" and 2. "2" can represent a nose, but so can 2 (or
II or ..), just as the word "apple" can represent a nose and an actual apple
can represent a nose (OK, both are quite stupid, but we could do it).
You are supposed  to be acquainted with numbers fundamentally representing
things, since kindergarten. There is no meaning in numbers if they don't
represent anything.
You confuse numbers and what they describe, the numerically describable part
of reality. Numbers are conceptual, and a concept that doesn't represent
anything is empty, meaningless. That's my criticism all along.

Actual existing relatively speaking. Ultimately you are right, what we
really interact with is consciousness itself, only in the form of an apple.
Maybe saying "actual, existing object" was saying too much, and I should
have written "concrete material object".

Of course they are. Rather both numbers and computer science are not useful
in the context of explaining fundamental reality.
This is obvious, really. No computer program makes any sense in terms of our
experience (beyond programing and understanding programs) without something
that converts it output into something experiencable, that can't be itself a
program (a screen, a speaker,...).
As you have programed a lot, you should have noticed that all programs can
be interpreted in many different way if you output them (output something
that is supposed to be sound as a picture, or a text file). The programing
language itself may contain words like "sound", but still this is not
necessarily how the hardware interprets it.
COMP has the same problem, computations don't unambigously define any
experience at all (really every [infinite sheet of] computation could be any
experience when it comes down to it, you can just associate all computations
to the non-numerically describable aspect of the experience), and therefore
it is quite meaningless. Yes, maybe quantum logic can be derived from the
fact that computations don't unambigously define experience , but this
solves no hard problem that isn't already solved, which is expected from a
theory like COMP. Especially as it claims to be able to derive physics.

There is no assumption needed. Smells and roses arise in and out of
consciousness, as you can plainly observe for yourself. If you make a loop
on your computer, nothing will happen in terms of smells and roses. You try
it. Maybe you are convinced after the 100000x try.

It is not a strong statement, since no purely digital brain is possible,
because there are no purely digital things at all. All actual device have an
analog component to them, which is non-turing emulable - simply because they
are not computational.
You could say this is the assumption of something non-turing emulable, and
indeed it is. You simply can't emulate something that is not definable at
all in terms of emulations. It is too fuzzy, there aren't any rules to
describe it. Reality is fundamentally fuzzy, quantum mechanics' "precise
fuzziness" (which can be emulated because it is precise, in terms of
probabilities) is just an approximation (we already know quantum mechanics
can't be completely correct).
What is you argument that reality is not fundamentally non-turing-emulably
fuzzy?

No process in the brain is turing emulable, so I can't find a particular
one.

Nope, I just need to realize that something that is not at all definable
can't be emulated. In order to emulate anything one needs are reference
point that can in some way be described. This is not the case with reality,
even though there are many *approximate* reference points.

You want something that can be mechanically/scientifically describable in
nature which is not turing emulable, which of course will never happen.
Nothing in nature is turing emulable, there is simply no reference point
that could define how to emulate it.
If you restrict your own view to that which is allowed by your own view
(just precisely describable things count), of course no one can show the
opposite.
What is emulable are the numerical rules that we found out it, but this is
just obvious, since all (provable) number relations can be expressed with
every programming language.
But we can't emulate plants or brains as such, as it not even definable what
plants or brains precisely are, so how could one emulate them?

Yes. Bodies are bodies, and therefore not machines in the COMP sense. Even
COMP entails that as far as I understand it (from the 1-p perspective), but
still claims bodies to be turing-emulable for all intents and purpose, which
is a near contradiction, or at least very implausible. It simply wishes away
all non-turing-emulable components (claims them to be just 1-p phenomena).
Why would nature make bodies 1-p non-turing emulable if all relevant aspects
are emulable?

I doubt that this is possible. I think brain in the vats will just appear in
dreams and imagination, and there interaction / entaglement is quite
limited.

Right, because I is consciousness and is not a machine. Of course strictly
speaking direct experience does not contain a statement that I am not
machine, it is simply that I don't call my observation as such "machine",
because that would just be totally confusing.

I simply observe that God is not a theory, and therefore any theory is
insufficient to capture "him", all theories are merely reflection of some
aspect of God. That COMP is more false than other theories is pretty much
just a subjective statement of this person, in that COMP is quite useless in
predicting things. Frankly I think for God every theory is equally false, as
he can't even understand any theory (he doesn't understand, he is aware).

What? You never provided any argument without natural language. Of course,
since no one could understand such an argument.
Other theories don't claim to rely solely on something axiomatly definable
like numbers. All valid physical theories admit that they stem from
observation, which is not definable.

I don't believe that the truth can be known at all, so no, I don't. I think
COMP is a bit mad, but "meaningless" is more of a correct word probably.

This is not a concrete prediction. This is just a statement that a
prediction and a experiment is possible.
I could as well say "my theory of the ??=/-logic produces uncountable of
experiments,... I just yet have no clue what they predict and what the
experiment looks like. But it will be some quantum stuff, as my theory is so
fuzzy, so up to now it is confirmed".

COMP is so fuzzy and meaningless that you can derive anything from it (as
long as it adheres to us being digital machine), so this is no wonder. See,
you even derive that we are no machine, but that this is "only" the 1-p. You
flatly derive a contradiction, and then justify it by making the
contradiction "just" appear from the 1-p of view, as if there is any other
view that matters.
Really this is what the COMP conclusion is: From the 1-p of view, COMP is
false (since I am not a machine from the 1-p of view). So you can only
rescue it by pretending there is fundamentally 3-p of view. I wonder why I,
as having a 1-p of view, should give a damn about what a supposed 3-p of
view says.

Part 2 of sane is a mish mash of vague (eg what exactly is a true belief?)
and incredibly complicated statements. Or, I could say, there is no way I
can understand this stuff, and I doubt anyone really does (you admit
yourself that there are many many big open problems, which really means you
don't understand it in depth, either).
But mainly, you just end with as many open questions as you start with. At
the end, there are no conrete predictions, or even equations, just the
statement "qualia are themselves described by sorts of quantum logics".
Fine, but what do these predict? How do I know they don't just say "Whatever
the qualia is, is the qualia. Whatever is measured will be the measurement.
There are lots of possibilities for both."

This jargon could as well mean "The physical laws are whatever they are.".
If you want me to convince it is more than this, just give a prediction.

Then just use that to make any prediction. How do I know that the result of
these logics are not something entirely trivial, which is for all intents
and purposes a total non-prediction? Even if the logics seem non-trivial,
how do I know that they don't collapse either way, in the end result?

Right, when we are talking about intellectual knowledge I really am

I can't find abstract digital machines outside of my intellect, it is as

But I can't take that situation as meaning, when I then proceed to apply it

That's like saying if reality would be other than it is COMP would be
refuted. With this logic every theory is refutable, just by saying "If
100^100 pink unicorns would live in my garden then my XY-theory would be

But a actual digital brain substitution is not a precisely defined

Honestly, I won't bother to study a theory in much depth that I hold to be
utterly implausible at the start.
You really show a bad sort of professor mentality here. You give me a bunch
of complicated semi-nonsense, which is really impossible to understand (one
may understand technicalities, but these really solve no question at all)
and as long as I don't understand it (forever), you will say I must study
more until I am really able to critisize what you say. But you are unwilling
to discuss the very fundament of your theory (then you claim I don't even
understand stuff from high school or primary school, or maybe at some point,
kindergarten).
That's a nice strategy to be "right", that's for sure. "You just don't
understand it, study more".

A good theory, in my opinion, is open to criticism if you just know the
basics. That's why our good old physical theories are so good. You just need
to know their predictions, and can verify that they have been tested, and
mostly confirmed. And they make no claim to completeness, making criticism
that they are not completely accurate invalid (except someone claims they
are exactly accurate). If I critizise their ontological fundament, one can
simply say that they just make predicitions, and the ontology they use is
just describing what is relatively phenomenological real/significant in
regards to the theory - their ontology is limited to some part of reality
and does not constitute a fundamental ontological claim.

So if your theory is good, you should make predictions (not retrodictions!)
that can be confirmed and you should make no claim that it is a TOE, as this
claim is an implausible claim for every theory (why should it be?).
Especially bad is if you make no predictions and then claim it to be TOE, as
than it is not even falsifiable that it is a TOE (and even worse, you claim
to make predictions which turn out to be non-predictions for all usual
standards of prediction). Also you postulate an ontological fundament that
is very questionable.
Due to all of this, you will face a lot of criticism (or outright
disregard), and that's totally justified in my opinion.
Sorry, I like that you want to rigorously go beyond materialsm, but your
theoretical framework is just not convincing at all.

This is something I can understand. It just doesn't make sense in the

This propositions have actually something to do with measurable qunatities,

I think the main point were I disagree is that anything in computer science
has any meaning at all without relation to concrete things. No machine can
prove anything on its own, it is only our interpretation of their
functioning that makes it possible that they "prove" something.

That's trivial, given that there is no body, if we are immaterial machine,
so the only possibilty is that it appears from them.

First person indeterminacy will be a consequence of every sufficiently vague
theory, as it is more vague to say that the first person events are
indeterminate. This is far too trivial as to be a useful results of a such a
complicated theory, especially for refuting it.

Yes, just like magic gives some picture on the body apparition, "well, it
just appear somehow",

No, I don't, but at least I don't pretend having any intellectual answers.
When I talk as if I did I am just pointing to the obvious, which really
answers no question at all, in a sense that our intellects usually expect an
Just saying "It is obvious" doesn't satisfy our intellect, but that doesn't
make it false.

Fine, this just doesn't relate at all to the supposed results of COMP, where
no "french which are exactly 42 km high, in the year 1998" are mentioned,
neither my bank account.

Then we are using them as symbols, which have nothing to do with numbers in
particular, we could also have phone numbers made out of letters of the
alphabet.
The phone number 20042 is not 2*10021 or 20041+1.
It seems you are confusing symbols and what they represent. :P

Yes, because we can abstract from that. But we can't *completely* abstract
from that, otherwise our numbers aren't numbers anymore, really.

I acknowledge that we can use integers as a programming language (even
though it is as useful as "whitespace"). The problem is that programming
language and their programs have just meaning relative to their particular
uses, like creating and output on the screen (even though some programs may
be of use in many particular cases, but still they need some particular
instantiation). You want to eliminate the output part, which doesn't make
sense to me.
Yes, in an abstract way we can use machine to talk about dreams, but not in
any very much other way than we could with the symbol "." (and then
explaining that "........" means "the dog in my dream", etc...).

I think COMP abstracts so much and is so vague that it becomes meaningless.
Maybe you could replace my "extended" brain with a digital substitution, but
then I am would bet on the substitution level being so low that we would
have to substitute all of my neighbourhood that is at all relevant to me
(including all visible stars, etc...). It would just work because then the
usual immortality of consciousness would make my experience invariant,
because the old world would just cease to exist in one history, being
replaced by a consistent one were no replacement happens. That is, if a
substitution at that level takes place, the requirement of consistency (and
immortality) would lead me into a history were no substitution took place,
and because this history is as consistent as the original the substitution
was "successful".
Isn't this a way to say "yes doctor" that avoids the conclusion? Because I
say "yes doctor" only because I know that actually no substitution takes
place for my future self, as I will be lead into another consistent history
were this didn't happen (even though my past self was being substituted).
And if the substitution actually is not determining at all what will happen
to me, because it *practically* does not happen, the conclusion of COMP does
not follow. I just say "yes" because I don't mind being substituted, not
because I believe it is successful in any way beyond that it doesn't matter
(just as it doesn't matter if I this whole universe ceases to exists, in
which case I will just find myself in another one).
So then I might grudgingly accept that COMP might be true, but won't accept
its conclusion for the reason above.
Uhm, as I think about it, it even has to be true according to my own
assumptions, since the digital substitution, if the level is low enough,
will necessarily end up being without any consequence :D Lol, so I actually
do accept COMP after all. Yet none of it conclusions follow, as they only
follow if I am actually a machine, and not if I just happen to survive being
substituted with a machine (or something arbitrarily else) even when I am
not a machine.
