In the future world, the two smartest groups may head in two completely opposite directions: one group goes back to the primitive. They return to family, nature, the body, faith, and real relationships, seeking answers in eternal, unchanging human nature. The other group rushes toward the future. They throw themselves into AI, robots, brain-computer interfaces, and a new productivity revolution, creating a new civilizational order out of the unknown. One moves backward, the other moves forward. But they share one common point: they no longer believe in the old world’s rules of the game. One seeks the source of civilization, and the other explores the next stop of civilization.
