Harari (history, Hebrew Univ. of Jerusalem) recaps the cognitive, agricultural, industrial, and scientific revolutions from Sapiens, his previous best seller, to highlight a shift in the locus of divinity, from shared beliefs about nature to gods to social systems and, ultimately, to humankind itself. He posits that current efforts to cure disease, disability, and death will result in biological augmentation that creates a human species beyond Homo sapiens and that this will necessarily happen along socioeconomic lines. Humanistic systems currently holding sway, such as capitalism or socialism, will disappear if humans no longer are subject to scarcity or disease. Accepting the current idea that all change is controlled by deterministic algorithms (social, biological, or computational), Harari foresees a future of data-driven technological utilitarianism if we continue to off-load decision-making responsibility to artificial intelligence. This work is speculative, obviously, and posits that if something is technologically possible, we will try it, not that we will succeed. It leaves readers with questions about consciousness and conscience and whether unrestricted data flow will necessarily lead to wisdom. VERDICT While still appealing to those of a political, historical, or anthropological bent who enjoyed Sapiens, this title will be equally thought provoking to biologists and technological futurists.
