Isn Colemak doomed to irrelevancy like Esperanto?
The main difference is that in order to communicate you need other to find other people that speak the same language. You don’t need to make other people switch keyboard layouts in order to use Colemak. It takes significantly less time to learn a keyboard layout than it takes to learn a language. I’m hoping Colemak will eventually overtake Dvorak, but unfortunately QWERTY will continue to be the standard forevermore.
