Music theory for the 21st century with notation from several centuries earlier. Hmm.... sorry but tracker's table-like views are much easier. And so are most DAWs gantt-like editors. 100 times easier to comprehend than notation having the same not written in three different ways, and then some.
I’m sympathetic to this viewpoint, but most music students in the classroom will be playing instruments or singing rather than working in DAWs.
The instruments, music, and notation all evolved together in a shared tradition that make them well-suited for one another.
The English language is messy as hell, and yet, here we are using it because it's a shared set of rules and symbols that pretty much everyone who wants to join in on this conversation already knows.
Same with staff notation: If you want to communicate music to other people, learning the slightly clunky but universally-known written language is generally the way to go.
