For what it's worth, it does bother me how much standard CS tooling and the mindset bred from it is stuck in the paradigm of exclusively textual user interfaces. Linear text has its advantages and value, of course, but, like, we know well by now that not everything is best thought of or manipulated this way; that diagrams and other modes of communication and interaction can be useful. (This has nothing to do with why I'm interested in category theory [it's not that my motivating goal in life was to draw commutative diagrams…], but it's a somewhat relevant thought to the discussion I've had all the same. We as computer scientists talk a lot about trees, and graphs, and this structure, and that structure, and also about human computer interaction, and the importance of design, and yet the only structure we allow ourselves expression via at the end of the day is text, text, text.)
