Carr's 2010 book, "The Shallows", develops this argument further. Discussing various examples ranging from Nietzsche's typewriter to London cab drivers' GPS navigators, Carr shows how newly introduced technologies change the way people think, act and live. The book focuses on the detrimental influence of the Internet—although it does recognize its beneficial aspects—by investigating how hypertext has contributed to the fragmentation of knowledge. When users search the Web, for instance, the context of information can be easily ignored. "We don't see the trees," Carr writes. "We see twigs and leaves." One of Carr's major points is that the change caused by the Internet involves the physical restructuring of the human brain, which he explains using the neuroscientific notion of "neuroplasticity." In addition to being a Pulitzer Prize nominee, the book appeared on the "New York Times" nonfiction bestseller list and has been translated into 17 languages.
