What kind of world are we building for ourselves? That's the question Nicholas Carr tackles in this important, absorbing book. "The Glass Cage" is not just a timely critique of society's growing dependence on computers. It's a riveting story of humankind's entanglement with machines. From the frozen hunting grounds of Inuit tribes to the "augmented reality" of Google Glass, Carr takes us on an unforgettable voyage of discovery culminating in a moving meditation on how we can use technology to expand life's possibilities rather than narrow them.
