> Without public domain, there is no advancement, as future authors cannot build upon earlier works. Uhh, literature does not work like technology. Authors can and do create entire universes out of whole cloth. Of course, they will be influenced by countless other works, but copyright has no bearing their unless it's a barefaced rip-off. In fact, I would guess that most creators want to create their own work rather than build on top of others'. Firstly, because of ego, because the work would be all their own. Secondly, this allows the maximum amount of creative ability without being shackled by a backstory that they had no influence on.
