I wonder if LLMs will stimulate ASCII formats for more things, and whether we should design software in general to be more textual in order to work better with LLMs.
I've had AI create ascii-art (Nethack-style) dungeon diagrams when I asked it to write me a D&D adventure. Last time I tried it these dungeon diagrams were completely nonsensical, but that was a few years ago.
I think ASCII art in particular is generally a weak point for LLMs; maybe they could do better if they used an image model. Other ASCII syntaxes using matched { } delimiters seem like they would be easier.
