>people will say shit like "Why didn't school teach me how to balance a checkbook" as if school didn't teach them basic arithmetic and the ability to read a single paper of instructions included in your checkbook by middle school.
Not sure I agree with this interpretation. It's like responding to "why didn't they teach CS" with "well they taught you discrete math and binary". Specialized instruction on applied mathematics is well worth pursuing. It's arguably the big reason Al many students end up thinking "I'm bad at math". They get no context on what it's really used for.
