Yes, Harari echoes this term in some of his speeches, asking what to do with the “useless class of people” that emerge in the wake of the AI Revolution. Instead of asking whether we should be evaluating the materialistic “usefulness” of human beings in terms of the purely economic value they generate, or even whether we should be pursuing technologies that will create these conditions, he satisfies himself with questions about how to keep the “useless people” out of the way with drugs and the Metaverse.
That, and the idea that humans are now programmable and the concept of free will is over. He and his son-of-a-Nazi mentor, Klaus Schwab, want to turn you into the Borg. Literally.
Harrari is a class A megalomaniac and psychopath. Study him if you like, but never let that fact slip your mind as you read his psychotic musings.
