“Homo Deus” takes off where “Sapiens” left off it is a “brief history of tomorrow.” What is the natural culmination of the scientific revolution, Harari asks. Humans acquired the capacity to interrogate and manipulate the physical, chemical and biological worlds, resulting in even more potent technological advances that surround us today. The second - the “agricultural revolution” - allowed humans to domesticate crops and animals, enabling us to form stable societies and intensifying the flow of information within them. From the birth of a slight, sly, naked ape somewhere in the depths of Africa to the growth, spread and eventual dominance of that species over the world, “Sapiens” split the story of humankind into three broad “revolutions.” The first, the “cognitive revolution,” resulted in humans acquiring the capacity to think, learn and communicate information with a facility unprecedented in the animal kingdom. Historians, scientists and academic pedants carped about its audacity of scope - but the book, modeled after Jared Diamond’s “Guns, Germs, and Steel” (a book that also received its share of carping and academic envy), presented a sweeping macrohistory, often marvelously. “Sapiens: A Brief History of Humankind” was an attempt to write a genetic, anthropological, cultural, social and epistemological history of humans over the last 100,000-odd years. To understand how Harari arrives at this conclusion, we might turn to his earlier book. It is not the specter of mass extinction that is hanging over us. There is no reason to think that organic algorithms can do things that nonorganic algorithms will never be able to replicate or surpass.” In Harari’s telling, the human “algorithm” will soon be overrun and outpaced by other algorithms. “Organisms are algorithms,” Yuval Noah Harari asserts in his provocative new book, “Homo Deus.” “Every animal - including Homo sapiens - is an assemblage of organic algorithms shaped by natural selection over millions of years of evolution. . .
