This book is about the history of Apple, Amazon, Facebook, and Google, unvarnished and unspoken. The secrets of their triumph – and the secrets that the corporations themselves have chosen not to advertise. The extraordinary trust of billions of users – and the subtle manipulations behind it. Never-before-seen computer algorithms – and the true goals they pursue… What are we grateful for, and why is it too late to curse the Quartet? And what tomorrow will be like in a world that plays by its rules.
