I see no way it could ever be proven or disproven that X causes qualia Y,
at least not proven to be true in anyone except for me.
And even then the proof would only be available to me.

Yes and that something it's doing is communicating between the
In most people the
has formed a connection between the 2 hemispheres for their entire life.
But if corpus callosum is severed, as they are in split brain
experiments, it's as if there were 2 individuals in the same body. If you
and I could communicate as well as the
callosum can then we'd be the same person, and so John Allsop (or Brent
Clark) might know what the others red quale was like, but Brent Allsop and
John Clark still wouldn't.

I can't prove it but it seems to me that subjectivity, like experiencing a
red or green quale, would require some minimum amount of complexity, and a
molecule is just too simple for that.

Yes, a primate needs to be able to tell red from green because ripe red
berries are good to eat but unripe green berries are not. But if our red
and green qualia were the opposite of the other neither of us would have an
advantage over the other. As long as consistency is maintained one qualia
label is as good as another.

Being smarter gives you a evolutionary, having a subjective experience
does not. And yet Evolution produced me and I know for a fact I have a
subjective experience, therefore I conclude consciousness must be a
byproduct of intelligence just as a spandrel is the byproduct of an arch.

I'm not certain what you mean by that. Behavior and qualia are not the
same but if Darwin was right then one is the inevitable consequence of the

The 2 quales are caused by different physical things (wavelengths of
light) so they form different mental labels (different combinations of

The 2 different wavelengths of light must have different mental labels,
otherwise you couldn't tell the difference between red light and green
Until you start providing some specific falsifiable examples in your
predictions, it's hard to know that you are talking about anything other
than just hand waving
Except for behavior nobody can or will ever be able to make a falsifiable
prediction about the subjective experience of other people. If you don't
make it an axiom that intelligent behavior and consciousness are linked
then there is every reason to believe rocks are as conscious as you are.
