I think this problem goes both ways. So even if we could get some kind of AI to translate the knowledge into verbal statements for us, it would be impossible, or very difficult, for anything resembling a normal human to gain "experiential knowledge" just by reading the verbal statements.

Mary isn't a normal human. The point of the story is to explore the limites of explanation. That being the case, Mary is granted unlimited intelligence, so that whatever limits he encountes are limits of explanation, and not her own limits.

I think the most likely reason that qualia seem irreducible is because of some kind of software problem in the brain that makes it extremely difficult, if not impossible, for us to translate the sort of "experiential knowledge" found in the unconscious "black box" parts of the brain into the sort of verbal, propositional knowledge that we can communicate to other people by language. The high complexity of our minds probably compounds the difficulty even further.

Whatever is stopping Mary from understanding qualia, if you grant that she does not, is not their difficulty in relation to her abilities, as explained above. We might not be able to understand oiur qualia because we are too stupid, but Mary does notnhave that problem.
