That doesn’t square well with the fact that notation keeps getting refined and improved. There is no pushback for genuine improvements. Biggest problem here is that there rarely are changes that clearly and meaningfully improve situation over status quo. I gave one example above, but overall, I am not going to take complaints about notation being obstacle to understanding seriously without concrete ways how to meaningfully improve it. You can of course keep complaining that it’s confusing, but without proposals for improvements, you’re actually complaining about the difficulty of substance, not the notation, and it says more about you than about notation.
