I don’t see any downside at all if it’s layered on top of some other (very capable) keyboard-driven UI that can do all the same things.
there doesn’t need to be a keyboard. just good hand gestures which can’t be performed by accident, and good face recognition software. if apple headset will have this, I’m gonna bankrupt.
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
