Notation is cool and just right, the more I learned the more I appreciated how great contemporary notation is. Yes it's challenging to read sometines but the subject is challenging too, surely you could try to simplify it for certain applications but you'd lose a lot of flexibility.
Fighting notation is like fighting piano keyboard which is also extremely convenient thing to play compared to other stuff, even to grid controllers.
The fundamental problem in music notation is that it was designed for an 8 note system and we use a 12 note system. It's.. fine I guess, they got those extra four notes in there and millions of people read music with no problems. But it does create a lot of confusion for novice readers who now think those 8 notes are somehow more important than the other 4 or that the sharps and flats are somehow half notes(they are not, all 12 are equally spaced on a log scale) and don't even get me started on the confusing terminology, there are 12 notes in an octet, semitones? a fifth? a fifth of what? it is seven notes or 3/2's there is no 5.
With regard to the piano keyboard, again not terrible, but it definitely is a compromise to fit the mechanical needs of the piano. I really like the design of the chromatic keyboard(ever see an accordion with the big hex grid of buttons, this is a chromatic keyboard), it has the advantage that whatever key you play a song in it has the same fingering, on a piano every key has different fingering, so there is a big skill barrier to changing keys that interferes with employment of such a critical aspect of playing.

Interestingly, the current form of a piano keyboard isn't only way keyed instruments have been laid out.
My mind was blown when I first saw a harpsichord with separate flat and sharp keys for example because I never considered the concept. I grew up with pianos so in my ignorance I never really thought about them being different.
I find conventional Western notation works quite well for communicating notes, rhythms, and basic expression, but it breaks down pretty quickly once you move beyond that. E.g. a lot of the common techniques on electric guitar (bends, palm muting, tremolo/whammy bar stuff, pick slides, slap/thumping, pinch harmonics, raking) don't really have a convenient notational shorthand. That's without even mentioning synthesizers (how do you notate 'gradually increase the filter cutoff here'?) and DAWs, samplers, drum machines. But it's definitely a hard problem: the more information you try to shove into a notational system, the harder it gets for people to keep track of what everything means. Plus you just start running out of easily distinguishable symbols at some point.
