> Putting it bluntly, on-demand learning is excellent for learning tools, but it sucks at learning concepts. This looks a false dichotomy to me. Concepts can be learned on demand as well. Talk to any professors in a theoretical STEM field (I assume their learning is as conceptual as one can get), be it maths, physics, stats, CS, or something, they would advise their grad students not to spend too much time reading through the tombs before starting research. Instead, they would ask their students to learn the concepts along the way when doing research. Of course, one needs to have solid foundation to learn concepts quickly along the way, but it does not conflict with the effectiveness of learning on demand. What matters is what to learn on-demand and how.
