I stopped reading it the moment Graeber starts to misinterpret the Upper Paleolithic burials as “princly” and casts communal buildings or monumental structures of the era as evidence of social hierarchy. Well, the book certainly stands head and shoulders above anything Harari, but it still strikes me as written to support Graeber's political views. It also makes the common error of judging prehistory by comparing it to apparent remnants of similar societies that survive to this day, which are, however, already an amalgamation of, or were heavily influenced by, many (surrounding) cultures that existed during history -- see e.g. Shinto which is nowadays a full fledged polytheism, but nevertheless exhibits clear signs of its animistic roots (and is thus considered to be an indigenous animistic nature religion, which is quite an oxymoron), etc.
