I really enjoyed Factfulness and in general enjoy his work and talks. But I would recommend also reading some of the criticism it received. Some really interesting discussions came from the publishing of that book
"Factfulness actually employs a biased selection of variables, avoids analysis of negative trends, and does not discuss any of the serious challenges related to continual population growth. A policy based on the simplistic worldview presented in Factfulness could have serious consequences."

Or am I misremembering?
