I was hoping he'd touch on how writing is "embodied" or "extended" cognition, ie how it allows for manipulation and reorganization of ideas in ways that are functionally similar to what occurs within the mind a la Clark and Chalmers' “Otto’s notebook” thought experiment (in which an Alzheimer's patient has written all of his directions down in a notebook to serve the function of his memory).
Or how the thoughts we have as we are writing shape our understanding, and so we come out with not only a written composition, but a new frame of mind; AI generated writing allows us to preserve our frame of mind—for better or worse!
There is something to be said for the ways in which coding, too, is an exercise in self-authoring, ie authoring-of-the-self.
