Ever wondered how Google will look in a few years? Come take a look http://www.nytimes.com/imagepages/2005/10/10/opinion/1010opart.html
or they will forget to renew google.com and will expire on..............: 2011-Sep-14. and will be just "Host not found"
seriously, it won't be long before data storage technology and costs get to the point where everyone will start recording every single conversation they have (like some US presidents have tended to do (to their own detriment (but that's another story (the point is that they could)))) and eventually uploading it or searching through the audio files using google or some other search technology... scary but it will put an end to those silly "you said that yourself" "no i didn't say that" "but you did say that" "i did not say that, i said" "you're insane, i swear you did say that" "no i never said that, i would never say that" types of argument
