Ultimately physics is just set of well defined rules (algorithms) and

More and more information is being shown to be a critical property
universe, in entropy, the holographic principle, quantum mechanics,
laws of information carrying capacity, extreme physical information
is not unreasonable, therefore, to consider the universe has some
The ultimate description of anything is information. Information
described in terms of anything else. You might say the map is not the
territory,. but I would argue that a map that is accurate in every
detail is the territory. There would be no way for any observer to
distinguish between the two. You might consider Ockham in the
thought experiment: Imagine there are two universes, one is the
universe in which we live, another is informational representation
in math. If observers in the informational version are as conscious
and I (I know you would say they are not but stay with me) then they
also consider their universe to exist physically, there is no way
to tell one way or the other.
Now if an informational universe is shown to exist in math, what is
reason for postulating our universe is somehow different? In what
"physical" different from an "informational" one, what does being
mean and what does it add which is not already there in the identical
informational one? Everything that happens in the physical universe
happens in the informational one, they have all the same laws, and
evolution through time. What distinguishes the "informational
atom" in the informational universe from the "physical hydrogen
atom" in the
physical universe? I imagine you will say something like "It has to
physical to be real", but I have never seen a convincing argument
perhaps you could provide one?
Hi again on this fine Saturday when I should be gardening.
You can 'imagine' whatever you want about the word 'information'.
It's missing the point.
Here in the _real_ world, where 100% of AGI research is using real
computers (or hardware computation of a model eg FPGA) to implement
an AGI. That is, to implement an actual instance of cognition. The
goal is the equivalent of human cognition. I'll spell it out
properly because it seems to me, after 10 years of intense effort,
that I've finally found a simple achilles heel, where the belief
system is shown to be inconsistent. That is, there is persistence
with a belief in X in spite of empirical evidence that X is false.
Like pulling Pinocchio the puppet's strings and then really
believing it creates a real boy.
==================== EL PROOF
1) We have only 1 benchmark natural general intelligence (NGI): the
2) Specific physics exists in the brain. The physics of cognition.
This is the physics of action potential propagation (AP) resonating
with a large, unified electromagnetic (EM) field system. The
relationship between AP production to EM field production is _not_
1:1. More than one EM field is consistent with one set of AP
transmissions. Call it AP/EM physics of cognition. It's what we have.
3) In the artificial instantiation of fire by humans, the physics of
combustion is retained. In the artificial instantiation of flight by
humans, the physics of flight is retained. And so forth. Without
exception. (except in AGI!). By extension, the way to artificial
cognition is to retain the physics of cognition. AP/EM physics.
4) If computing can literally duplicate human cognition, then by
extension, computing the laws of combustion should create flames.
REAL FLAMES. That is the logical result of a belief that computing
the physics (or worse, an abstraction of it) of cognition leads to
That does not follow. Flames are not representational. Some things are
Turing emulable, and others are not.
False. You can emulate digital computations exactly. You just beg the
question. You prove your premise.
5) The computation of the physics of flames has been computed _to
death_ for decades. NO FLAMES resulted. In general, no instance of
computation of a physics model of X ever resulted in X.
In a very Popperian way, we have experimentally already falsified,
decades ago, a hypothesis that that computation can produce human
6) A claim that a computer can deliver human cognition is false. QED.
To continue to believe that a Turing-based computation of a model of
cognition is cognition is thus empirically falsified and has been
for a long time. This is GAME OVER for purely computational AGI. Not
in a formal sense, but in a technological investment sense
consistent with every other instance of technological instantiation
of a natural phenomenon. What sort of idiot would you have to be to
invest in a new kind of match, where you try to light your cigarette
with a computation of the physics of combustion ... because that is
exactly what investment in computational AGI is doing.
The AGI research community has it completely backwards. Using fire
lead to a theory of combustion. NOT the other way around. Ditto for
cognition. We do not have a theory of cognition. We will get one by
building the AP/EM physics of cognition and exploring. Just like
elsewhere, computation of models is useful. But it's NOT an instance
of cognition. It can't be. We've proved it empirically already. The
AGI community is, in some sense, researching cognition. However,
that research cannot be claimed to ever be an actual instance of NGI-
style cognition. Because of that reality, we need to re-frame
expectations and investment directions.
IMPORTANT NOTE. Your 'it's information' thinking can be completely
right and it changes nothing, because computers are not manipulating
it. They are manipulating human metaphors for information in a
'physics-independent' way. So you can retain your particular
'information-centric' view of the universe AND believe that
computers won't create cognition. The two views are quite
compatible. This is all about the correct route to knowledge and
Sweet clarity at last.
I don't know why I didn't see this argument before. I guess I'm a
bit thick. Off to the garden.
