One of the major issues dividing the critics was whether Carr"s claim that the Internet has shortchanged our brain power is, essentially, correct. Many bought into his argument about the neurological effects of the Internet, but the more expert among them (Jonah Lehrer, for one) cited scientific evidence that such technologies actually benefit the mind. Still, as Lehrer, in the New York Times Book Review, points out, Carr is no Luddite, and he fully recognizes the usefulness of the Internet. Other criticism was more trivial, such as the value of Carr"s historical and cultural digressions-from Plato to HAL. In the end, Carr offers a thought-provoking investigation into our relationship with technology-even if he offers no easy answers.
