why does it have to continue on after the creator dies?
why not just a straight up fixed term, like 10 years?
In fact, I'd say that a fixed term is so overwhelmingly easier to participate in that it should unquestionably be the case. When you see the phrase "Copyright (c) 2001 John Thomas" then you can know that after N years, then the work is available for you to reproduce.. you don't have to track down all the possible John Thomases who claimed the copyright and find out if they are still alive or if they died in obscure circumstances some years ago, or if they were a corporation and the copyright term is a different beast. Although I agree that a short fixed term
like 10 years?
is actually reasonable, I would certainly support simplifying the laws to use a longer fixed one.. and I'm also sure that the copyright cartels are completely comfortable with the current state of affairs which are vague and in their favour and would fight tooth and nail to prevent such a change
