What made it possible for the human species to conquer the world, build a global digital economy, and still want more? What drives technological progress and economic growth in the long run and on a global scale? And how will technological progress, economic growth, and the overall prosperity of human civilization unfold in the future?  This book sheds new light on these big questions by incorporating findings from physics, anthropology, psychology, history, philosophy, and computer science in a brand-new theory of economic growth. Looking back across the millennia, it identifies five major technological revolutions which have transformed humankind's capacity to process energy and information-the cognitive, agricultural, scientific, industrial, and digital revolutions-and characterizes the new avenues of economic development which they have opened while also exponentially accelerating growth.
