PARAGRAPHThe authors rely on exhaustive research and extensive interviews with top scientists, innovators, and captains of industry to explore how four emerging forces-exponential technologies, the DIY innovator, the Technophilanthropist, and the Rising Billion-are conspiring to solve our biggest problems. Diamandis and Kotler examine the stunning impact these forces are having on categories of critical importance while establishing hard targets for change, laying out a strategic road map for governments, industry, and entrepreneurs, and giving us plenty of reason for optimism. Since the dawn of humanity, a privileged few have lived in stark contrast to the hardscrabble majority. Conventional wisdom says this gap cannot be closed. But it is closing-fast.
