A lot has happened within the past 500 years. Even the past 100 years. Can you imagine what it would be like to have an infinite amount of data such as video blogs, blogs, facebook profiles, email accounts, etc from people from hundreds of years ago? We'd have videos and audio of people like Leonardo da Vinci. Think about the year 2500 or even 2100+. There will be such a huge amount of data on the people living now. How cool would it be to be able to go back and watch YouTube videos from a few hundred years ago? Sure technology will change a ton by then but I imagine people will do everything possible to preserve data from century to century. I mean, perhaps this very thread will be talked about in schools in 200 years after being pulled from some archive. :lol: How creepy would it be to be able to go back and watch videos of people talking to their friends, read facebook profiles, etc. Whether these things are still around by then is one thing, but I think it's fairly safe to say that they will be archived somehow. Also, just look at the amount of news items that are archived daily on hundreds of thousands (if not millions) of websites? There will be so much stuff to read through (for those who even care) in the future. Talk about the ultimate in exploring past civilizations though. History books in a few hundred years (I say books but for all we know books will be gone by then) will have a ton more information just between now and then than everything we know about the entire world so far.
