This is pretty cool! I didn’t know they were recording stuff back in 1980!
Stanford has a nice playlist here.
Naturally it’s full of TeX & Mathematical writing, along with trees and other ‘fun’ CS stuff.
While we are overall drowning in cat videos, and other uh ‘multimedia’ content, it’s still amazing the wealth of information that is available to the world (well the part of the world that can view YouTube).
I have no idea what the licensing is, but it’d be such a shame if it was hosted on additional platforms to make them available to the larger world.
