Since 2001 Microsoft researcher Gordon Bell has been compulsively tracking every bit of personal data that he generates in his daily life, in the interest of finding out just how much digital storage it would take to contain it.
Bell, who works at the Microsoft Silicon Valley Research Group and is calling his project MyLifeBits, has stated that “The problem isn't putting it all in. The problem is getting it out. When I started, I couldn't find anything!” Currently Bell has been able to track all the web sites that he’s visited (221,173), photos he’s taken (56,282), emails he’s sent and received (156,041), documents written and read (18,883), phone conversations had (2,000), photos snapped by a SenseCam hanging around his neck (66,000), songs he’s listened to (7,139), and videos taken by him (2,164). In order to collect all this information he users a desktop scanner, a digicam, a heart rate monitor, voice recorder, GPS logger, pedometer, smartphone and an e-reader.
He does suspect that there’s some need to forget though. Being able to wipe clean difficult memories of the past could be some evolutionary trick. “If you think you should forget, you should,” states Bell. “But for God's sake, keep all the papers you've written and the photos you take. Sometime down the road you might be looking for something and you won't even give yourself the chance of finding it.”
