And objectively observe that observation of that particular phenomenon going

We'll never get anywhere with that approach, we need to use a different
tactic and we have one, behavior.

As you say this can have practical considerations, but I can find absolutely
no evidence that the way information is represented has any philosophical
ramifications at all.

Exactly, good qualia makes our behavior smarter and unlike consciousness,
intelligence can be tested for. They've improved a lot in the last few years
but even now no machine can do a job like picking ripe strawberry's as well
as a human, so I think it's safe to say that a machine's qualia of red is not
as rich as a human's. Yet.

I don't understand your objection, all information is abstract.

And a human brain can put a hole in a tape in the context of other holes and
so obtain information from that tape, but obviously machines can do this too,
that's why punched tape was invented and that's why feeding such a tape into
a machine does not produce random output.
>Red is like red, there is no other meaning required.
I agree, some things can not be reduced further, and I can give another
example. Intelligence produces consciousness, no explanation why is required
or possible.

Searls's Chinese Room is a foolish thought experiment that teaches us nothing.

Nothing to do with it?! I think it has everything to do with it, good thing
too because that's all you'll ever know for sure about the subjective
experience of another person or machine. If I'm wrong about consciousness
then random mutation and natural selection would never have bothered to come
up with it, but I know for sure that it managed to produce it at least one
time because I'm conscious, I have a strong hunch you are too.
I'll never be able to prove it, but I think the best way to make progress in
this area is to just forget about consciousness and concentrate on
intelligence, because you'll get consciousness anyway and free of charge.
That's the tactic Evolution took, in fact nature found that intelligence was
a much harder nut to crack than consciousness. The emotional parts of our
brains are very old, little different from that found in many other animals,
the higher brain functions, like logic and simulating the future so we can
make plans, operate in much more recently evolved parts of the brain.
Conscienceless is a dime a dozen, intelligence is not, If nature found one
to be much harder to produce than the other, why would the opposite to be
true when we design our machines?
