I am an avid listener. I listen between 75-100 hours per month on my iPhone: 60% fiction to 40% non-fiction.
In the demographic Cliff, Dent make a reasoned, well supported argument for his predictions. The first third of the book is very slow because he spends a great deal of time convincing you of his solid record in past predictions -- of course they have worked out well or why would he write another book?
That sarcasm aside, he makes a very convincing argument and it dovetails with other books like "The Next 100 years" and Freakonomics. I think this is a must read -- think it over, his argument does make common sense.
This is my first time ever writing a review. I am taking the time to do this to save you, the stranger I don't even know the horror of this lame and useless book. Hours and hours of droning on about these few boring people who magically were successful after going to Harvard Business School!? Give me a break, this book is insulting to me and to all the men and women who start businesses with little formal eduction, credit cards for financing and their spare room as an office. Instead of this pile of cow dung go read Rich Dad/Poor Dad before you quit your job, The 4 Hour Work week by Timothy Ferris, Rework by Jason Fried, The Happiness Advantage by Shawn Achor, and The Big Leap by Gay Hendricks. Unless you went to Harvard Business school, then read this and call all your friends and laugh about how fun it is to part of the ruling class in this country. Bill Murphy, you have brought shame on your family... fall on your sword.
