Then you would know from direct experience something about your
consciousness that nobody else knows, namely that although the replacement
part reproduces all the inputs and outputs that can be measured in the lab
there must be at least one I/O that can't be measured; and you'd also have
proof that consciousness is not a byproduct of intelligence and that
Darwin's theory was wrong, but unfortunately that proof would be available
only to you. But this is not a new situation, you don't need exotic thought
experiments, in real everyday life you know things with a certainty that
goes beyond mere proof about your consciousness, but although you know it's
true you have no way to prove it to others with mathematical rigor.
