I'd argue that any such mapping of inputs and outputs, (fully mapping our mind) would equally describe to a system that is not conscious. In other words, the whole analysis could as well be describing a zombie that behaves like us but does not have experiences.

Put another way, it would fail to capture why that system (our brains) produce any experiences at all. I know this is disputed, of course. But I basically think the hard problem is a real thing: https://en.wikipedia.org/wiki/Hard_problem_of_consciousness
