~Theoretically, you could figure out every book you've ever
   read, every TV show and movie you've ever seen, every website
   you've ever visited. Also theoretically, you could trace back a
   large percentage of the names of people you've ever known, from
   school, work, neighborhood, online. Then to each you could make
   sublists of "What makes this [x] meaningful to me?" and add
   things until you can think of no more. Where you could go from
   there, I don't know honestly. But there's a lot of potential
   data collection that could make such an effort partially
   possible. Of course, the same two people can read the same
   books, TV shows, movies, know the same people, have nearly
   identical experiences yet are entirely different. Still, it
   could be an interesting project. == Quite true - yet what about
   the subconscious influences? There could be underlying
   assumptions that guide the rationalizing process that you might
   not be directly cognizant of but could be revealed by knowing
   the entirety of influential input. Perhaps things you haven't
   used yet. Something from a movie you saw when you were 10 that
   hasn't yet been needed - its influence not required just yet,
   but one day its significance shows itself through life
   circumstance. That sort of thing. For a decent AI, it would not
   only have to capture the present and the past but would have to
   be able to predict potential futures. ==
