why use latex (and this is coming from someone who prefers Word to latex):
- much better tooling than any other format
- much more discussion on various problems you'll hit.
- much more training data for chatgpt and other LLMs, so your personal assistant can help you with latex syntax. good luck getting that level of support for typst or any other new programming language.
- network effect -- if your professor only knows latex, you can't use typst. and professors are slow/reluctant to adopt new shiny tech. if it has worked in the past 50 years, why change it?
