> ...ask a musician if they are really in the weeds of why the instrument is producing music (the physics behind it!). They are probably aware that it's vibrating air, but, in general, they won't know the theory behind it.

A big difference is that, unlike computing, their instrument probably won't stop working because of some subtle change to physics introduced by a seemingly-unrelated change made to the universe by some other party in the musical instrument / air / molecules / atoms / quarks "stack". Theirs is a world with some assurance of stability.

Ours is a field built upon shifting sands. Knowing what the foundations are that the edifice you've constructed sits upon allows you to affect repairs when it crumbles unexpectedly.
