Eddie, your answer is quite thoughtful and experienced and you can tell that mine is somewhat shallow due to me picking up music late in life.
I agree our brains should be #1 on our lists and that brain science is a vast and interesting subject. In theory, I get the right brain/left brain differences but in my brain it's all just one (musically limited but learning) brain

I can also appreciate how music theory would be high on the list for many.
