Just look at the book testimonials to see how anticipated this book has been: Bill Clinton; Eric Schmidt; Ray Kurzweil etc. it's currently shot to #1 on Amazon for the entrepreneurship category of books.
Love this book and his previous one, Abundance. This one is more practical than the previous, laying out steps for utilizing exponential technology for building businesses.
