I think it is a momentum problem. You learn to use a keyboard when you are young/inexperienced, because you need to learn something, and then learning something new is hard and slows you down, so you stick with what you know. It's doubly hard to both create a new layout and learn it.

I would offer ‘swipe’ keyboards as one example of something new. “better” is subjective, they are certainly not faster than normal typing, but offer much more flexibility for typing with one hand. But even then they still rely on the old qwerty layout. Not sure how widely adopted they are but they come standard on IOS and Android keyboards

I would argue that the DataHand/Svalboard counts.
