At the recent Association of National Advertisers annual conference in Phoenix, Google Chief Executive Eric Schmidt, was asked how long it would take to index all the world's information. In response, Schmidt replied: "We did a math exercise and the answer was 300 years".
There are approximately 5 million terabytes of information out in the world and so far, only about 170 terabytes have been indexed.
Just think, in 300 years every single bit of information will be easily accessible with just a few clicks- and people will still be forming opinions based on U.S. media, tabloid newspapers and what some bloke down the pub told them.
