And if we take reductionism as a strongly supported axiom (which I do), then necessarily any explanation of consciousness will have to be describable in terms of data and computation.
This is a tautology.
To me, the “axiom” is no more than a hypothesis. No-one has come up with an alternative that does not reduce to “magic”, but neither has anyone found a physical explanation that does not also reduce to “magic”. Every purported explanation has a step where magic has to happen to relate some physical phenomenon to subjective experience.
Compare “life”. At one time people thought that living things were distinguished from non-living things by possession of a “life force”. Clearly a magical explanation, no more than giving a name to a thing. But with modern methods of observation and experiment we are able to see that living things are machines all the way down to the level of molecules, and “life force” has fallen by the wayside. There is no longer any need of that hypothesis. The magic has been dissolved.
Explaining the existence of subjective experience has not reached that point. We are no nearer to it than mediaeval alchemists searching for the philosopher’s stone.
