The natural evolution of this technology is to insert it into human communication channels and automatically transform raw thoughts into something better for the other end of the channel. "Better" is open to interpretation and going to be very interesting in this new world, but there are so many options.
Why not a version of HackerNews that doesn't just have commenting guidelines, but actually automatically enforces them? Or a chrome extension that takes HN comments and transforms them all to be kinder (or whatever you want) when you open a thread? Or a text input box that automatically rewrites (or proposes a rewrite of) your comments if they don't meet the standards you have for yourself?
