Western music notation is designed for efficient reading of western classical music. It is neither designed for easy writing, nor for easy reading of arbitrary music.

Well, we can agree on that, for sure. Western music notation feels a lot more biased than e.g. mathematical notation, and I think there are "language" aspects to it. Most spoken languages at some point are not very logical, and they could make small tweaks to be more logical, but they don't. I think WMM is like that, and there's nothing I have seen so far that makes it universal and absolute. In particular, I think there could be alternative music notations that preserve all the qualities of the classic western one, but improve on the "pay off" efficiency (it would be quicker to learn). E.g. there is nothing inherently accidental about the accidental notes. People just happened to favor C major for whatever historical reason. And favoring major and minor scales, by the way. Music today is far more diverse and we need music notation that breaks those biases.

I am equally triggered by claims that WMM is perfect and you just need to accept it and practice until you're good. :))))))
