Hold on, I never said completely abolish copyright for nonfiction. I suggested reducing it to 10 or 15 years. Most pop sci will have no economic value after 10 years, so it shouldn't change anything. It's utterly ridiculous that an out of print 1950's textbook by a dead author, is still protected by copyright. How is society benefiting from this arrangement at all?
