I agree with you in many ways. Lots of learning can happen much more effectively in a project environment. I would say about 70% of a modern STEM degree can be based on projects. But lectures have their place. A lot of times, you need information transfer from someone who knows a lot to someone who knows little. I am in favor of video lectures with active learning components to self-test yourself. Also, subjects like Mathematics, require a lot of practice of, perhaps, boring questions. While some practice can and should be done collaboratively, a lot of it has to be done individually. There is no substitute for that.
