edit: I couldn't figure out why I was a little confused reading this, but it's because there is no one coherent answer in this article.
edit: I asked because the article doesn't answer that, aside from a small sampling. And the phase before this seems to be from only a couple of years ago ("Aaron Leitko wrote a 2011 Pitchfork feature about it called 'Positive Destruction'.") I don't know SF, but I've seen gentrification up close a few times in larger US cities, it usually takes longer. Hence my question.
Something like BBC/PBS "Universe" stuff from the late 90's aged very well because they are snapshots of discoveries and problems that now are not nearly as exciting anymore, but they tell you a lot about the very recent history of the subject. This goes for a lot of other subjects, whether it's art, or math, or history. Documentaries can be historical documents in themselves, just check out "Civilization" from 1970 (I think), or "The Human Animal" from 1994.
Soundtrack, narration opening, editing, those all hold clues to trusting or not trusting the content, and it's pretty easy to establish credibility and historical context early on. But they can also be the equivalent of an amazing lecturer.
Edit: one obvious addition to the biography section would be "The Quest For Tannu Tuva", parts of an autobiographical interview with Feynman, on YouTube as well. Edit 2: "The Strange Life and Death of Dr. Alan Turing" from 1992 as well.
