I think it’s a little naive to equate “on-demand learning” with essentially learning frameworks or tools.

I remember early in my career when I got a request to make a graphic slowly start to circle around a user’s mouse as they hovered over an area of the page.

I couldn’t use a tool to solve this problem. I used on demand learning to go back to high school trig and figure out how to animate something in a circular motion.

My point here is that often on demand learning and conceptual preparation merge into the same thing and aren’t mutually exclusive.
