Libraries are where people can sit and read and contemplate--and think. Online sources by their very nature are helping lower our patience with reading long, detailed works.
We are getting dumber and dumber, and the rise of the Internet, while providing ample sources of factoids and gotcha! journalism, is training our young people to be sheep. The inability to sit and read and pause to think is not a good thing.
The dumber part is because of unions destroying the education industry. People leveraging the internet are much smarter than they would be otherwise. Give an average person 2 extra hours and an internet connection and they could ace the SAT.
