I did find him to be a hell of an interesting thinker and someone with very interesting ideas, but to me, the whole book had a smell of overconfidence and incredibly weak standards of evidence. Very much in the "well I observed this phenomena, went for a walk and though deeply and clearly the reasons is X", followed by a tower of (interesting) conjecture built on top of X.
I put it down to coming from the economics culture rather than a more rigorous scientific culture.
