Agreed, that a technology solution would only be as good as the database that was used for learning. But that is the same as a human - they are only as good as their knowledge extends. However a high-res scan (or other measurement method) can pick up things that the human eye cannot.
Personally, I think one of the biggest hurdles for technology would be that if it were more repeatable than human graders, and I don't think that is a stretch, that it would virtually eliminate re-subs. Not good for PSA's business model.
OK, carry on. Back to discussion of the cards.
