Beyond total capture: A constructive critique of lifelogging

What if we could digitally capture everything we do and see? What if we could save every bit of information we touch and record every event we experience? What would such a personal digital archive be like, and how might it affect the way we live? This vision of a complete “lifelog” is the holy grail for many technologists and researchers who consider us to be on the brink of an “e-memory” revolution.
In the past few years, capturing “Memories for Life” has become a U.K. Grand Challenge in Computing (http://www.nesc.ac.uk/esi/events/Grand_Challenges/proposals/), and many research programs today are dedicated to developing technologies to support the archiving of vast amounts of personal data.
