Thank you. Indeed, the top-down/bottom-up view of education is analogous to the efficiency of breadth-first vs. depth-first searches in different problems. Depends on what you want to achieve. The reason I use these is I think a lot of suffering comes from (or can be defined as) churning on deep-node problems without information from higher level concepts, and a notation that "locates" meaning in an broader ontology can relieve some of it, and yield new understanding. I think this is a theme Ted Chiang is on to as well, as it appears in the literary world as well as STEM.
