Nice question, ambivalents, and thanks for the recommendation, yesenadam. Very cool. I just started watching the first video of Sapolsky's lecture and found it to instantly capture my attention. I'm going to stick to this series. By the way, studying Sapolsky could also help with the forum question recently in Ask: HN about explaining things well to people.
His lectures look like a neat place to get a deep anthropological grip on things.
It's accessible to laymen, no prior knowledge needed. It covers so many different fields and levels of knowledge ("buckets" Sapolsky calls them), different ways of explaining human behaviour. By the signals in their brain, or the hormones in their blood, or what happened that day, or their childhood, or their genes, or evolution of humans etc. Also looks at other animals. A lot of touching/funny/inspiring/poignant stories about scientists in the field(s). Sapolsky is an amazing lecturer/raconteur.

The famous "You and your research" is one lecture in this, but every one of them is fascinating. History of computers, AI, codes, n-space, digital filters etc etc. Mainly it's great seeing how his mind works, his thinking style. (I've since read a few of his books, and I love how they're soaked with practical experience, in the same way these talks are. It's all stuff he's lived.)
