What accounts for substitution level? Is it a hard threshold whereby Pinocchio becomes a real boy suddenly, or is it a gradient of escalating qualia? Either way seems insufficient for the same reason that vanishing or absent qualia seem unlikely. If Pinocchio spontaneously opens his eyes one day as a fully realized human being, that would have odd subjective problems (do they project a simulated history in their memory or do they know that they came into existence today but know everything about the world and their own lives?) or do they gradually come online with morbid in-between states of tortured semi-consciousness without means to express or relieve their discomforts? > > > You would agree though that a ventriloquist does not transfer > > the ability to feel, see, and understand to his dummy, I assume, so > > doesn't that mean that the difference between a wooden dummy and a > > machine capable of human feeling is just a matter of degree of > > complexity. > > No. The dummy should behave the same in presence and absence of the > ventriloquist.

It sounds promising, but without an example it's oblique to me. It's critical acclaim of an idea that I haven't been able to get out of the intriguing packaging. Isn't there some natural language example you can give me of the theory - without variables or big picture generalizations? Can you tell me a story about one particular number and why it has developed a belief, or one particular qualia that is explained by a particular computation theory? > > >> I think the hard problem is 99% solved, and 100% metasolved.

Cumulative entanglement is a way of encapsulating or recapitulating computation (sort of literally 'coming to a head') - but, I don't think it gets to the heart of the matter at all. It doesn't address the qualitative quality of qualia. To say that consciousness has a role in a machine universe is putting the cart before the horse. It is the machine that has a role in supporting consciousness. To say that consciousness has a role in computation is to say that a screenplay has a role within a movie set, but that the stage and props are primitives from which movieness arises. > > > It diminishes the relevance of how significance is achieved through > > qualia, minimizes the intensity of biological commitment to survival > > and things like the difference between pain and pleasure. > > I have no clue why you say so.

But you shouldn't you refute the use of Newton physics to predict weather when people suggest that there is no problem in doing it?
