>Feel free to point to anyone doing these deep dives that specifically tackle the lost knowledge of the early decades of computer science
I skimmed through the video because I don't have two hours but there's no lost knowledge in it, he's going over well known papers from Dijkstra, Hoare or Knuth. The paper he bases most of the talk around Knuth's Structured Programming with go to Statements is his most often cited work, there's a very high chance you'll encounter that early in any undergrad course. So the answer to your question is, pretty much at any local uni with a CS course.
The well known papers are not what the talk is about though. The talk is titled "The root of the root..." specifically to go over the specific and incredibly/almost impossible to find citations those well known papers used and built upon to see what historical insights that might have been lost went into how those papers are now interpreted (or as the video argues, misinterpreted).
