Yuval Noah Harari did not invent Big History, but he updated it with hints of self-help and futurology, as well as a high-altitude, almost nihilistic composure about human suffering. He attached the time frame of aeons to the time frame of punditry—of now, and soon. His narrative of flux, of revolution after revolution, ended urgently, and perhaps conveniently, with a cliffhanger. “Sapiens,” while acknowledging that “history teaches us that what seems to be just around the corner may never materialise,” suggests that our species is on the verge of a radical redesign. – The New Yorker
