"For documents whose source is likely to be shared or handed over to other pe ople, writing in TeX rather than expecting them to learn a new language is still good citizenship."
Conversely, my entire interest in Typst is have an input format more efficiently read by AI. We've passed the inflection point where one can responsibly only write for humans.
Typst is Markdown-adjacent, while PreTeXT is XML-adjacent. More characters but even easier for AI to process. I'd switch for the HTML and ePub support, but no syntax coloring for code blocks?
