[ExI] Why stop at glutamate?

The insistence of Jason, I, and others in "PATTERNS is all what there is"
has its foundation in our training as physical scientists.
It is clear from studying modern science patterns are what is fundamental
in nature. In physics, we go further and in fact, we say everything is
fields which is an even more abstract concept.
You bang on the table and say "but it is hard" and I tell you it is all EM
fields in the table that repel fields in your hand. Y
You are looking for something concrete when it is all abstract fields. You
can measure them, you can manipulate them but there is nothing solid. Also,
patterns are where the information is. When we insist that redness is just
a neural pattern we really mean it.
This is important, VERY IMPORTANT, because as I said before it is about
modeling. If you know how to model something you can recreate it. I gave
the example of the experiments of Berger where he could reproduce memory in
a chip by reproducing the patterns (he calls them spatio-temporal patterns)
that memory consists of.
Models also tend to be as simple as possible. If I can get the same result
with fewer components then that is a great model.
Human physiology is often a Goldberg machine, physiological processes are
overcomplicated, they go in a roundabout way to get some desired
results, and very inefficient. We can improve the efficiency of some
processes, for example, memory or even consciousness by understanding what
is essential and eliminating the rest. That is what modeling is about.
Can you stop for a moment and reflect on that and tell us how that
understanding of what brain stuff really fits in your understanding of
"quality of redness"? To me is completely incompatible because it is not
about glutamate or any other physical substance but just the patterns, just
the relations. These relations can be recreated digitally and you can
re-create any brain stuff including the sensation of color.
Do you understand why this is a big deal? It is a completely different
vision of how the universe works. This is why we believe computers can be
conscious because it doesn't matter what they are made of. If they have the
right patterns then they can do whatever the human brain does.
