I agree, and add the reasons you state to ones I already have.

I anticipate that in the future it will, as you say so well,
be shown that "appropriate brain states necessarily lead to
conscious states", except I also expect that by then the
meaning of "conscious states" will be vastly better informed
and filled-out than today. In particular, the concept will
have migrated from a mix of 1st and 3rd person notions, to
entirely 3rd person notions. I speculate that after this
occurs, people won't consider the old 1st person notion to
be of much value (after all, you can't really use it to
communicate with anyone about anything).
But of course, all that is just speculation.

Yes, but I don't think that there is any answer to the "hard problem".
Concretely, I conjecture that of the 100000^5000 or so possible strings
of 5000 words in the English language, not a single one of them solves
this problem. But if so, then even after the scientific problem of
learning what brain circuits are probably necessary and sufficient
to capture all conscious appearing behaviors, then there will still
be people who feel mystified.

I agree that nothing is for sure; yet I'd expect that they'd have
incentives to metabolically survive, and have a will to exert
control over their immediate environments just as we do. So there
would eventually be negotiations, and I'm confident that even
empathy for them would develop.

It's possible that we have reached that point so far as I'm
concerned now; thanks for continuing.
