“Writing on a manual [typewriter] makes you slower in a good way, I think. You don’t revise as much, you just think more, because you know you’re going to have to retype the entire fucking thing. Which is a big stop on just slapping anything down and playing with it.”
Typewriter is free software that doesn’t have backspace, delete, or cut-and-paste functions. A la manual typewriter.
Or stone tablet.
