It's out of your control. Art and copyright. And everything.

Writing in the free world | Salon Books:

"If you make stuff, it is not yours to command its destiny in the world. God help you, you should be grateful if it has one. It's fantastic if anyone cares. Every artist should be constantly reminding themselves how lucky they are if people are even bothering in the first place.

...I don't think 50 or 100 years after my death, someone should still have say over what someone makes of this stuff. It certainly doesn't follow. As Lawrence Lessig likes to point out, you can't provide incentive to a dead creator to make more art by offering him a copyright."
