Don’t think anything can actually replace the power and expressiveness of keyboards and text interfaces- that’s always going to be the bottom layer for a productive setup (i.e., you need to actually be able to write code, write shell scripts etc to control your machine, etc).
Guess what I really want is just some kind of Unix machine that hums along 24/7 in the background, with many different paradigms for interacting with it when you don’t have (or want) a standard keyboard and display. Putting a display over my face feels like a giant leap in the wrong direction
