To be clear, I am talking about phenomenal consciousness — which is simply the ability to subjectively experience the world and ourselves. This is distinct from metaconsciousness.
Bernardo Kastrup on phenomenal consciousness:
>Our phenomenal consciousness is eminently qualitative, not quantitative. There is something it feels like to see the colour red, which is not captured by merely noting the frequency of red light. If we were to tell Helen Keller that red is an oscillation of approximately 4.3^1014 cycles per second, she would still not know what it feels like to see red. Analogously, what it feels like to listen to a Vivaldi sonata cannot be conveyed to a person born deaf, even if we show to the person the sonata’s complete power spectrum. Experiences are felt qualities — which philosophers and neuroscientists call ‘qualia’ — not fully describable by abstract quantities.
>Some genius comes around with a computer that given the necessary input, provides the solution...but now they do know that it's computable.
Can you give me a concrete example of input/output and how we would validate any output? You are suggesting the that the brain is the program, the physical world is the necessary input, and consciousness is the output (correct me if I'm wrong). But if I wrote a program to make a perfectly accurate simulation of a kidney, would you expect it to pee on my desk? Of course you wouldn't, so I'm not sure why we would expect that of the brain and consciousness.
Going back to your example, which I like, even if we had access to the code, the code is not the actual reality. It is an abstraction. We can dig through the code all we want, but we will never reach electricity and transistors, the true reality of the program. I think this is analogous to our own reality, where we can dig into spacetime at smaller and smaller distances, but never find "true reality". A hint that this is the case is the lack of operational meaning to distances https://www.youtube.com/watch?v=Uz-Ve_1LX8w); the amount of energy required to probe those sizes creates a black hole. So something must* be underlying spacetime. I think that something is phenomenal consciousness, mind-at-large, pure subjectivity, call it what you like. Spacetime is the source code, and phenomenal consciousness is the electricity and transistors.
