To your point, I didn't even look at the code.. :) Okay, I looked at the codex code. it's super reasonable -- separation of concerns, operating on a state model, it's not over designed. I did not hate it. I also noted that codex put in a CRT simulator loop which is a nice touch.

I think a year ago this would have taken a lot of back and forth and arguing; to me that's kind of the point of Simon's article -- a lot more just 'works' now.
