Thirty years ago Bill McKibben offered one of the earliest warnings about climate change. His groundbreaking book The End of Nature was the first book to alert us to global warming. But the danger is broader than that: even as climate change shrinks the space where our civilization can exist, new technologies like artificial intelligence and robotics threaten to bleach away the variety of human experience. Falter tells the story of these converging trends and of the ideological fervor that keeps us from bringing them under control. Falter is a powerful and sobering call to arms, to save not only our planet but also our humanity.
