I can't wait until the computer programs we make are smart enough to organize, sort, and put forward this information, with large amounts of understanding, at a moments notice. There is so much information, spread around, about all our lives, our pasts, the things that define who we are, especially with facebook and so on being a thing. It may well be that in the future a random person can just find any person and get a somewhat realistic idea of who they really were, what the times were like, what drove us to act. Right now, it's such a massive amount of information, and so few real structures or man-hours are set up to deal with their organization that it's all going to waste. I get the feeling that "machine learning" type dealing with all this will be the next huge thing to hit society.
Isn't that the problem the semantic web is supposed to solve for us? That's if anyone can be bothered to implement and use it. It seems too difficult and too time consuming to do it manually, so I think the only way it can work is if AI becomes good enough that we can start automatically categorising things like video, pictures, speech and text. There is some progress there, but it's still al long way from becoming mainstream and accessible to all.
