It's not about effectiveness; lectures are the added value that the university system provides to the educational process. I don't need to be paying thousands a year to have someone point out the best videos to watch online, or to pick problem numbers from a math textbook, or to come up with project ideas, or any of that. The whole point of lectures is for experts to share their knowledge. Universities are (ideally) a funding mechanism to ensure that there is enough capital to support those who want to teach, and they generate the capital by keeping many of those lectures private. I would 100% rather watch a live person give a talk than burn out my eyes on another online video where I can't even ask real time questions.
