Nicholas Carr, author of the book "The Shallows: What The Internet Is Doing To Our Brains" argues the Internet is robbing us of contemplation.
The way the brain works has been altered each time a new medium is introduced, and he claims that the Internet is the "most effective mind-mutating technology of all time". Due to new innovations such as Twitter and the iPad, people are now used to surfing and skimming short bits of information, and this reduces their attention span and depth of thinking.
"We're not just losing the capacity for those modes of thought. We're redefining them as expendable. If we don't see this as a problem, then there won't be solution to it."
