I don't think that's a good analogy. In your example, we still end up with a perfect "copy" of all the data and behavior. When it comes to subjective perception, there's simply no way of even "copying" the information by simply writing it down. * (caveat follows below) So, in the Mary example, no matter how much she "reads" about the color red, she really would not "know all there is to know" about it. * Now it might be possible to encode a neural state on paper, and if you have a machine that can "apply" that state to your brain, then you can read that paper, enter codes in the machine, and let the machine "fix" some neural state in your brain so you can experience the same "thing". At least it seems like this should be possible in principle. Although it might not be practical .. depending on how perception is "implemented" in the brain.
