I love this idea: Future of Music.
It is a subversive misappropriation of systems for music recommendation and automatic playlist generation to help you find and suggest you remove data from your music collection based on your tastes. And on top of that, the application is created by a co-founder of a commercial music recommendation business!
Can we make a system that will go through my numerous travel photos and delete the ones that are not composed very well, or that do not have interesting enough subjects?
I wonder if a business can be built around this idea.
