    Not if consciousness is the inevitable byproduct of intelligece,
    and I'm almost certain that it is.


If consciousness is necessary for intelligence, then it's not a byproduct. If on the other hand, consciousness is just a useless byproduct, then it could (logically if not nomologically) be eliminated without affecting intelligent.

You seem to want it to be both necessary but also be something that makes no difference to anything (which makes it unnecessary).

I would be most curious to hear your thoughts regarding the section of my article on "Conscious behaviors" -- that is, behaviors which (seem to) require consciousness in order to do them.

    I have no problem with that, actuallyit's very similar to my view.


That's good to hear.

    Right. You could even say that "computer program" is not a noun,
    it is an adjective, it is the way a computer will behave when the
    machine's  logical states are organized in a certain way.  And "I"
    is the way atoms behave when they are organized in a Johnkclarkian
    way, and "you" is the way atoms behave when they are organized in
    a Jasonreschian way.


I'm not opposed to that framing.


        /> I view consciousness as like that high-level control
        structure. It operates within a causal realm where ideas and
        thoughts have causal influence and power, and can reach down
        to the lower level to do things like trigger nerve impulses./


    Consciousness is a high-level description of brain statesthat can
    be extremely useful, but that doesn't mean that lower level and
    much more finely grained description of brain states involving
    nerve impulses, or even more finely grained descriptions involving
    electrons and quarks are wrong, it's just that such level of
    detail is unnecessary and impractical for some purposes.


I would even say, that at a certain level of abstraction, they become irrelevant. It is the result of what I call "a Turing firewall", software has no ability to know its underlying hardware implementation, it is an inviolable separation of layers of abstraction, which makes the lower levels invisible to the layers above.
That's roughly true, but not exactly.  If you think of intelligence implemented on a computer it would make a difference if it had a true random number generator (hardware) or not.  It would make a difference if it were a quantum computer or not.  And going the other way, what if it didn't have a multiply operation.  We're so accustomed the standard Turing-complete von Neumann computer we take it for granted.

So the neurons and molecular forces aren't in the drivers seat for what goes on in the brain. That is the domain of higher level structures and forces. We cannot ignore completely the lower levels, they provide the substrate upon which the higher levels are built, but I think it is an abuse of reductionism that leads people to saying consciousness is an epiphenomenon and doesn't do anything. When no one would try to apply reductionism to explain why, when a glider in the game of life hits a block and causes it to self destruct, that it is due to quantum mechanics in our universe, rather than a consequence of the very different rules of the game of life as they operate in the game of life universe.
