I used to use LaTeX pretty frequently and although I was reasonably productive I also never felt that I "knew" it. It was a whole lot of googling "how to do x in latex" and pasting in something that was too arcane for me to remember for next time (and/or copy pasting from my own prior documents)

In all honesty, I only ever did it to achieve the "LaTeX look". These days I write in markdown or (gasp) wysiwyg editors like google docs.

Thanks to pervasive use of LLMs I predict the future is mostly markdown. It’s the defacto output format for every LLM. It’s simple, plaintext and easy to version control.

Hell I wish I could submit my resume as markdown.
