I'm arguing that a screw is not the same thing as a nail because when you
hammer a screw it doesn't go in as easily as a nail and when you use a
screwdriver on a nail it doesn't go in at all. Sometimes the hammer is a
better tool and sometimes the driver is. As humans, we have a great hammer
and a decent screwdriver. A computer can't hammer anything, but it has a
power screwdriver with a potentially infinite set of tips.

Have you tried thinking about it another way? Where does 'mapping' come

Maybe you do. Maybe a lot of people do. I don't think that I do though. I
think that a game can be played directly without abstracting it into

I don't doubt that this game is likely to be solved eventually, maybe even
soon, but the fact remains that it exposes some fundamentally different
aesthetics between computation and intelligence. This is impressive to me
because any game is already hugely biased in favor of computation. A game
is ideal to be reduced to a set of logical rules, it's turn play is already
a recursive enumeration. A game is already a computer program. Even so, we
can see that it is possible to use a game to bypass computational values -
of generic, unconscious repetition, and hint at something completely
different and opposite.

Sure, but mine doesn't pretend to be as it calls the whole notion of
falsifiability as a criteria for addressing awareness into question. Strong
AI though is a bet that awareness can be constructed through logic, and
logic, especially digital logic, is all about the exclusive supremacy of
true/false positions. I don't think that Strong AI is a bad goal if it
drives curiosity and development - my beef with AI is completely
incidental, I generally am happy with computer science and consider it one
of the few healthy parts of civilization that remains. I only argue against
Strong AI because when I argue for this new picture of
mind-matter-information unification, the argument that fights back is
rooted in these assumptions about information states being concretely
real...information states which we have knowingly contrived for the purpose
of developing technology. We invented the Gigabyte and now we worship it as
a mechanical anti-God. It's more of a public service than anything else to
try to point out why that may actually prevent us or side track us from
understanding consciousness. Strong AI may not really want to understand
consciousness, and that's fine, but for those who do want to understand the
physical phenomenon of awareness, they are being led down a dead end path
by some very smart, very enthusiastic minds.
