But Mary does have all this data in her room - she knows every last interaction of wavelength to eyeball to neurons from her studies. What doesn't Mary know in her room? You're proposing that you can codify that in some special (data-fied, 'factual') way that she couldn't possibly have access to in her room. What is that codification, then? Be specific. If you (we) can't do that, then aren't we just lunatics screaming and uttering and pointing at conscious experience with no ground?
