Could Joyal’s encyclopedic knowledge be encoded in software? Probably. But no one would make enough doing so to put a Rolls in the driveway. It’s just too small a category. The same is true of Claire Bustarret’s work. Johns Hopkins Magazine reports that Bustarret “has made a career out of knowing paper like other French people know wine.” Her ability to determine from a sheet’s texture, feel, and fibers when and where the paper was made is extremely valuable to historians and art authenticators. Maybe what she knows could be put in a database, and her analytical techniques could be automated. But in the meantime, she would have learned more.
