Query: all flash no substance

After reading this book all I can say is "so what?". Yeah sure the world is changing, fast, old rules don't apply, heard that a 1000 times before, but what the authors fail to do is give insight into what might work, where they think this fast paced future is taking us. The only insight was is borrowed quotes and clichés. Kinda like reading cotton candy.
