Agree that note-taking impairs the purpose of lecture which is to impart 1-2 key thoughts/derivations. I'd take this to the logical extreme and claim university lectures are largely vestiges of a past when the replication and distribution of monographs was expensive, and audiences were often the speaker's peers who could benefit from live interaction. The advent of the internet and the commoditization of post-secondary education have dissolved these two motivations, and the fact that colleges charge the same tuition for recorded lectures during COVID-19 belies the longstanding "dirty" secret that college is more a third-party seal of approval than a place of genuine learning.
