Sometimes, I lie awake at night and worry about copyright. I then start worrying if this makes me irreconcilably weird.
I worry both for our American culture, as items have stopped falling into the public domain and becoming available to re-use and re-mix, or simply to re-present for free. If this doesn't seem like a problem, this video on a 6-second drumbeat will blow your mind - especially if you then read this story about an artist being sued for a 1 minute clip of silence making fun of John Cage's 4'33" of silence. The artist ended up settling out of court.
I worry more generally about international trade and development, as we inflict ever-tighter IP regulations on countries we give aid to or trade with - regulations which we scoffed and flouted during our own development.
We're no longer protecting innovation with these laws - we're protecting the first movers (often big, established businesses), and encouraging gaming the patent system to try and get the most generic and sweeping patent accepted.
