most mathematicians and theoretical physicists don’t know what the business end of a spanner is, either. mechanical engineers have a fighting chance at knowing, and tradie apprentices assuredly do. This is less surprising simply because those disciplines and their relative abstraction hierarchies are older, more well understood, and more clearly delineated. CS is less than a century old.
