alt Hacker News> Lectures have been an incredibly ineffective way to learn forever.
Mainly due to shortage of very good lecturers, no? I can not see a better way to cultivate the professional pride than to attend lectures of truly remarkable professors. The style, the manner, the attitude go much beyond the dry proofs. I'm an applied math major.
You're describing your response to a performance, not to a learning opportunity. Is it fun to watch a great performer? Sure. Is that an effective way to learn? No.
Does lecturing have a place in disseminating ideas? Sure. I love that scene from Oppenheimer when he attends Heisenberg's lecture, being exposed to cutting edge ideas directly from the mouth of a truly remarkable professor. Watching that gave me a better appreciation of lecturing's original purpose and historical importance. But that's very different from teaching well-understood concepts and skills.
