I listen to Harari's class and think of the changes as if in a different dimension.
Humankind lives in a world of dreams shaped by words: god, baryon, evil, gravity, ethics, news, travel, terror, carbon, freedom, greed, enemy, consciousness, measurement, family. Some words have interpretations which can be discussed mathematically; we call those discussions science. Some words do not: we call those discussions, humanities. Science does not tell us how to behave, that is the realm of the humanities; however, it gives us information to help us understand and evaluate potential actions.
