This is the same kind of logic that leads to whiteboard algorithm questions. Music theory and musicianship are not the same thing. There are many many great musicians who only enough to make the sounds they want to make. Sure they might be better if they took the time to learn, but not necessarily.
I’m curious if you are a musician? This description of music theory (whiteboard algorithms) feels really off to me (feel free to look at my sibling comments as to why).
If it’s your experience as a musician I would like to understand why.
