The keyboard and screen UX was established in the 1970s. I've been using a keyboard and screen to work with computers since the 1980s. I am quite sure I'll be using a keyboard and screen until I retire. And probably 50 years from now, we'll still be using keyboards and screens. Some things just work.

Touch screens, voice commands, and other specialized interfaces have and will continue to make sense for some use cases. But for sitting down and working, same as it ever was.
