There are many other criticisms in the Reception section such as the below excerpt which is a good summary of how I felt about what I read of the book.

> The historian David A. Bell, responding solely to Graeber and Wengrow's arguments about the Indigenous origins of Enlightenment thought and Jean-Jacques Rousseau, accused the authors of coming "perilously close to scholarly malpractice."

They are real scholars but also trying to use their reputation to sling a narrative to sell a book for the masses. I don’t care that some of their Ivy League/anthropology buddies said it was a breath of fresh air, what I read and researched myself said it was a good amount of hot air.
