I think we'll still be using physical buttons/switches 73 years from now, and qwerty keyboards will still exist. The qwerty layout will definitely be around.

I think we'll still be using physical buttons/switches 73 years from now, and qwerty keyboards will still exist. The qwerty layout will definitely be around. Hardware keyboards will be a niche compared to all the other kinds of input types we'll have in the future. I'd like to say that hardware keyboards will be the domain of knowledge work but 73 years is a long time.
