Maybe a "Paircast[0] for lecture notes"-type application could help with this. Records audio, maybe even transcribing it (if high enough quality), while also tracking how the notes relate to the audio across the time of the lecture.

As for lectures in the past, it is a shame we may have lost them, as it seems to me (purely speculatively) that the lectures from the 70s and 80s seemed to make a whole different class of programmers to the ones of today. Or maybe it was the tinkering and not the lectures, who knows.
