I saw it on PBS when it first came out. 20-30 years ago?
It is a terrific analytical study, although the geopolitical aspect is outdated now. Its still worth watching though, not for its Cold War references, but its anthropological insight.
My own thinking was very much influenced by it. As I recall, I was a cold warrior myself at the time, a Silicon Valley spook.
I didn't realize it was on Youtube. I highly recommend it, if you've got the time to sit through all of it..
