I completely agree, yes. But you are missing the more important point
which is, if this theory can be falsified, as you are doing, you simply
need to come up with a variation on the theory, till you get one the
experimental science effingly proves is the one. It has a large part to
do with both what has the quality, and how these qualities interact with
the binding mechanism. It could be that only neurons and, and
neurotransmitters can have and bind together qualitative properties.
And that we will never find a way to integrate stuff like CMOS,
qualitatively, directly, as you predict. But, again, what matters, is
the general framework where you can determine what does, and what does
not have qualia, and it is not different than the rest of science, as
long as you include this qualitative information that is intrinsic, and
not just zombie information being interpreted as if it was the real thing.

But you are leaving out the binding system. The only way what you are
claiming could be true is if there is no theoretically possible way to
do what you are assuming can't be done. But there are many theoretical
possibilities which could bind, effingly, multiple qualities, so you are
aware of redness and greenness, at the same time, and that you can know
the difference because of this qualitative binding. The neural wave
theories that Steven Lehar talks about are just one example of many
possible theories that can bind together waves, over areas of time and
space, which falsifies what you are claiming, that you cannot bind
together things like this, to be aware of both of them, qualitatively,
at the same time.

Again, I completely agree with this. But the higher level testability,
qualitatively, still applies. When you are aware of redness, there must
be something, that is detectably causing you to be aware of this. And
there must be something that is detectably different than this, which is
reliably responsible for us being aware of greenness.
Since no functionalist, ever gives any possible way to reliably detect
this difference, even if it is an obviously falsifiable difference, it
makes it hard to use functionalist theories to talk about the more
important part of how to falsifiably detect what is, and is not
responsible for redness. All you need to do is replace glutamate, with
whatever you could possibly predict is detectably responsible for redness.
I've tried to find any possible way to detect, functionally, what is
responsible for redness, and how this could be different than some
functionalist greenness, but I can't, without it being circular, and not
defined anywhere. If you can provide any way to test for this, I will
be glad to include the predictions you provide, along with the different
predictions being included with materialist theories, so we can both
leave it to scientific demonstration to prove, which is right. But till
you can provide how to test for what you are claiming, there isn't much
I can do. Seems to me you must admit that if a materialist theory,
works, and you can use waves, or anything else to bind them together, as
you predict can't be done, you must admit that functionality would be
scientifically proven wrong.
And the same is true for detectable functionalism. But, we must first
find, either theoretically or experimentally, some reasonable testable
theory which is detectably responsible for us experiencing a redness
