This is like saying functional programming languages miss the fact that application software is written with objects. Alternate approaches to notation aren't meant to supplant traditional notation. It'll be centuries before today's notation goes anywhere. It's very well established and does indeed do a good job of representing traditional western music. New notations just make other styles of music more legible, which makes it easier to compose them, and easier to perform them. There's no competition involved, nor anything being doomed to failure.
