Would robot librarians do better?

Eric Roger Green Has A Column in The Denver Post:

There is no proof that one can have a truly balanced library collection based on all the ambiguities involved. Librarians will continue to receive collection challenges, which they should. We need to communicate that there is no perfect system. Our patrons must also understand this as well. We can challenge our patrons to take responsibility for this process. We might achieve a respectable, but imperfect representative collection. Or would robot Librarians do better?
