Many of the people on this list (in common with a lot of western
philosophy at least since Descartes) are hoping to construct their
existence measures on the bedrock of the objectively decidable
self-awareness.  They've built very interesting structures, but you
may notice there's been no progress at all on stabilizing the
foundation.  Instead we have on this list the same debates that
endlessly, repetitively and inconclusively flood comp.ai.philosophy,
never mind philosophy journals and books.

Gerard O'Neill, the late Princeton physicist best known for his space
colony studies, once said that if you met a race that insisted that
logical developments must be built step by step from a firm
foundation, you could be pretty sure they were planet dwellers.  Races
that live in space realize that it's perfectly OK to build structures
that have no foundation at all.  They can be circular and unsupported,
yet if you spin them they'll have gravity just like the ponderous
planetary piles!

I think your insistence on the absolute underpinning of an objective
consciousness is just planet-bound thinking.  Bruno's, Juergen's,
Russell's or Max Tegmark's analyses can just as well be built on
arbitrary selections of what's conscious (Turing test passers?
biological brains? red-haired people? teddy bears?).  The teddy bear
universes may have different probabilities than the biological brain
universes or the Turing test universes, but so what?  Each is as
likely to be self-consistent as another.

i.e. You don't have to give up the goals of this list just because you
don't believe there is an objective fact of the matter to

Don't need it, don't want it.

So does a lookup table.  Just ask it, it will tell you all about
its complex motives and internal mental life.

Groundhog!  I make no such assumption.
