Query: Great Insight on how the world will change

Most of us have some inkling of how the communications revolution might affect the way we work and play in the future. Cairncross extends those thoughts and comes up with a series of conclusions that you may or may not agree entirely with, but surely are thought provoking. Good summary of the key points on the first few pages, all of which are expanded with good reasoning in later pages. If you like the style of the Economist, you'll like this book.
