Nicholas Carr’s authors an opin entitled, "Is Google Musing Us Stupid."
Carr argues that the Internet is changing the way we process information: “What the Net seems to be doing is chipping away my capacity for concentration and contemplation,” he writes. “My mind now expects to take in information the way the Net distributes it: in a swiftly moving stream of particles. Once I was a scuba diver in the sea of words. Now I zip along the surface like a guy on a Jet Ski.”
