A better way to conceive of creativity
Kirby Ferguson: Embrace the remix : Video on TED.com
I wonder how long it will be until we're able to track elements (melody, lyrics etc) in one song to other songs. And by "we" I mean, computers, automatically and without help. There are already sites displaying the make up of actual remixes by artists like Girl Talk - all manually built.
When someone builds an automated version, it'll be interesting to see what happens to copyright law. I imagine we'll be awash in this kind of case for a while. With luck, copyright laws will be softened, rather than strengthened, else creativity become the exclusive domain of companies with large IP portfolios.
