I am an avid listener. I listen between 75-100 hours per month on my iPhone: 60% fiction to 40% non-fiction.
Friedman offers us a prognostication of the future 100 years. His fortunetelling is based upon geopolitical factors rather than hocus-pokus or astrogeology. He offers very sound reasons for his thinking the future history lines. Given that this book was published in 2010 and only four years into it, we already see some seeds of truth. Four years is only 1/25 of the span but at least he is off to a great start. Given this a listen, it will make you think -- especially about the middle east and the far east. I give it a thumbs up.
