This series has been going on for a while now, for three other parts surprisingly.
The others (available here) discussed the creative evolution of film and music, and how they have incorporated the work of everything previous to create something new.
This one discusses the evolution of ideas, and how we all want to own what we’ve done. Intellectual property is from my head, so you can’t steal my work because I thought of it.
Essentially, creativity is being ruined by our own want to own everything we’ve ever done.
