I've been recording everything I say and hear for the past 5 years, with the idea that eventually I'd be able to transcribe it and run all sorts of amazing analysis and insights on the data. Thought, learning and vocabulary evolution. AI replicas. Digital immortality.
Everyone is walking around with a microphone and camera in their pockets. Recording video of people is still too visibly creepy (until we have cameras hidden in RayBan-style sunnies), but recording audio from your pocket is something you can do without causing a shitstorm around you (*yes, legally you should tell people you're recording them).
So we launched a startup a few years ago called Lifebox: http://lifeboxapp.com, but even now it's still too ahead of its time. Obtaining funding was impossible. Once we move past this era of privacy concerns into a sousveillance culture, it's inevitable that everyone will want to record and stream their lives 24/7.
