Is it off-topic to simply say that expert-level explanations of some topics explained meaningfully may make for boring or out-of-reach lessons? Is it useful to learn multiplication before addition? Or exponentiation before multiplication? Or tetration before exponentiation? I mean there's arguments that if addition and multiplication both must be learned then maybe linear combination is a more useful end-state target for the lesson. I'm not begging the question to refute your point. These are important questions, and I worry that society isn't seeking the answers, because as far as I know students still learn "times-tables" even though we have handheld computers capable of, from a photograph: reading, interpreting, and solving math problems from a description, so that those tasks are as contained as an arcane reference like integral lookup tables. I see a world where students instead learn even finer machinery, such as logic, encapsulation, and organization rather than obsessing over whether they can rhythmically remember what 11x12 is for the rest of their lives.
