> Part of the issue is that the loudest voices are that 0.01% of authors whose work still has some commercial value decades after its creation.
My favorite scheme is that all copyright last for 10 years by default. You can register it for $100 for another 10 years. And every 10 years after that, the cost goes up by 100x. That way commercial works that are very economically valuable can be protected for a pretty long time, but everything makes it into the public domain relatively quickly.
Maybe the numbers need to be tweaked a bit, but I think the idea is fundamentally sound.
