This document discusses Lawrence Lessig's views on intellectual property law and how new technologies have historically been seen as "pirating" existing cultural works. It provides examples throughout history of technologies like the player piano, radio, and VCR that were initially seen as enabling piracy but later were regulated and the law adapted to them. The document discusses DJ Danger Mouse's remix album combining songs from the Beatles and Jay-Z albums and whether such remixes should be considered illegal or if the law should change to accommodate new technologies and cultural mixing enabled by those technologies. It provides several other examples of popular remixes and mashups and questions around who owns the cultural works involved.
