But that does this *mean*? These are just a bunch of words. You could as
well write
"It means that when you colmüd the pööl of ämpod with itself you get
the pööl of trübda, or the pööl of the pööl of ämpod.".
If you just have a bunch of words without being able to make sense of them,
everything you "derive" from it will just be whatever you happen to
interpret in a bunch of non-sensical words.```

Yeah, so I ask what is the meaning of being realist about it? I can't see
any. The only meaning is when we work with countable objects, or
measurements, which indeed follow some rules that mathematics describe.

We could as well say that our definitions make the answer to that question
well-defined, even if we haven't yet figured out what the answer is. This
doesn't mean that the answer describes an independently existent entity.
I agree that our definitions make sense and describe something, but they are
not a thing in and of themselves. In my view numbers are valid descriptions
of a certain aspect of reality, but this doesn't mean they have any
independent aspect. That is, I don't think our mathematical formulation of
numbers describe numbers as a thing of itself, but rather are a particular
expression of regularity in awareness.

OK, but why would one believe in mathematical realism? It seems more
plausible to me that abstract entities seem to have their own life because
they mirror the life of the non-abstract enitities; but they have no life of
their own. I've never seen evidence of a number apart from countable things
and measurements. The axioms of numbers are just non-sensical (or mere
symbols, open to all interpretation) if not interpreted with respect to
measurements, or countable objects. What does 1+1=2 describe, if not that
one thing and another thing, which are concrete objects that do not
interact, give two things of the same kind.
I treat numbers as a locally (not in terms of space obviously) valid theory
of our world - OR as symbols being capable of representing everything (just
as all other things like apples) -, and I haven't yet seen evidence that
it's more than that.

The funny thing is that if you don't give any plausible meaning to numbers
as thing in and of themselves, apart from countability or measurements, you
are just pulling things out of your imagination. Of course you can derive
everything from something that can represent everything (of course it is
possible to represent whatever you wish with the symbols of mathematics).
I have nothing against imaginative use of symbols, but please don't pretend
it has a solid foundation other than that, if you can't even give a

You didn't see my point. The actual thing I was referring to was not an
concrete physical object, but the object of your theory, the supposed
"numbers". As long as you don't give a explanation of what they are, apart
from mere definitions that could mean anything, of course you can derive
everything from that unexplained mystical thing.

It doesn't help to agree on elementary propositions if they could mean
anything. Or it does, but than we should acknowledge that we just interpret
whatever we wish into something that is so vague as to mean anything. Of
course I am willing to accept 1+1=2, it sounds good. But if you derive
something precise from that, you should be able to say what exactly that
means, otherwise you just showed your ability to interpret symbols that are
so broad as to mean anything in abitrary ways.

concrete things. If they do, you wouldn't need to resort to concrete things
to show what they mean.

But then they make no sense as the basis of a TOE, which includes
non-discrete, non-countable, non-measureable, non-comparable,... things.
You need to use Gödel to make sense of it, by using numbers to represent
things beyond them. But then you use numbers as representations, which is
"cheating", as representations can represent anything, which somehow makes
the use of numbers totally empty. It is not even wrong to do, though it
seems to go beyond the axioms of the numbers. Where is the axiom that
numbers can represent things (for example mathematical symbols?).

I am just seriously doubting that there is a 3-thing. What is the evidence
that numbers are a 3-thing that exists apart from the 1-perspective?
I agree with your conclusion that "The "real"  reality with comp is
epistemological". But I think that ulitmately ontology=epistemology, if we
define knowledge broad enough. The only thing in existence is
self-knowledge, or better (self)-awareness.

You are, too, so how do you know of an "outside"? I think it is WAY more
plausible (or rather the only plausible alternative) that there is none,
because I (We), are the only thing that exists, without an outside view.
Outside view exist relative to persons (objects within consciousness), not
relative to consciousness (which is I, or we).

I can accept that, but they exists secondarily to existence itself, which is
not an intellectual construction at all. They are a particular view on
existence, and they don't exist on their own. And therefore COMP does not
make sense, or rather is misleading, because it pretends to "just" use
numbers (or other equivalent constructs), where really it just uses numbers
to talk what is beyond them.

Of course, everything we can speak of is an idea. I am not speaking of
reality as an idea, but reality as reality itself.

But it seems natural to me.

None. Or "What is is what is". Existence is self-existent, and
self-revealing as awareness. There is no theory for it, as it is an absolute
creative singularity which escapes all theories in a way that every new
theory creates even more things to explain. It has to be that way, because
theories itself are just a representation appearing within awareness, and
therefore cannot capture awareness (which I treat as the ultimate reality,
as it is the only thing which undoubtably exists).

Yes, and my point is that this is just your interpretation of what COMP
means. We could just as well say that saying "yes" is just a bet with no
further consequences. Your reasoning depends on vague and quesitonable
assumptions, and therefore is not necessarily valid.
"Yes, doctor" itself is vague. What is "me"? What is an "experiential
change", and what constitutes awareness of an experiential change - it seems
to me that experiential change always occurs, making it already impossible
to substitute without an experiential change. Also I am critical of AR, as I
explained above.

No. The mandelbrot set as a meaningful entity is not made of definitions,
but of geometrical interpretation of the definitions, which are of course
possible and very meaningful.
And Gödel's discover is in my opinion better expressed with "The
arithmetical reality is FAR beyond ANY attempt to define it, as soon as we
use arithmetics to point to the transcendent reality, which of course is
beyond definitions". But this has *nothing* to do with arithmetics in
particular. It is just as true that the kööpül reality is FAR beyond ANY
attempt to define it, for just the same reason. Nothing can ultimately fixed
by any definition, even the simplest logic can't define it's own basis, as
it is not even clear what true, or false means. Every definition relies on
something that is beyond definitions, and thus no definition is meaningful
on its own.

OK, the point is that it is just a definition, and as such doesn't mean
anything without our interpretation.

It doesn't matter. You get the same problems I described above with other
universal systems (they are just other bunchs of definitions).

This is all nice and well, but I am precisely questioning your goal.
Actually many of your conclusion sound good and right to me, but it doesn't
have to do anything with digital mechanism in particular. You are just using
the fact that universal systems are useful for representing EVERYTHING. I am
only critizing your claim that this has to do anything with (abstract)
universal systems in particular.
