This book will probably get fairly negative ratings, as the readership is bound to be a tech-savvy audience that doesn't like the message.
Don't let that stop you from this masterful manifesto on the dangers we face from whole-hearted acceptance of the internet. Though Keen at times goes a bit far in his critique, the core of the message is on point. We threaten to destroy vast realms of our culture in a careles unthinking shift toward infinite digitization. While being Luddites is no good alternative, we should at least consider the ramifications of the world we are bequeathing for our children.
I don't agree with all of the message, but the book is well-written and powerfully stated. Regardless of your position, whether or not the internet is "the answer", Keen's perspective is a vital one to consider.
