As I am writing this:
There are 255 million websites and 152 million blogs online, 35 hours of video are uploaded to Youtube every single minute, 119 millions tweets are posted every day...
It is estimated that a week's worth of the New York Times contains more information than a person was likely to come across in a life time in the 18th century.
3000 scientific articles are published every day, that's about one every 10 seconds.

My point? There is much more information that is getting produced than one person can possibly absorb. And it just gets bigger and bigger. We are living in exponential times...
