This. It's also hilarious how bad LaTeX actually is at maths despite it being overwhelmingly used for exactly that purpose. Instead of worrying about mathematical semantics, you constantly have to make typesetting decisions. There are workarounds (use your own custom, semantic commands), but still. And yet, everything else seems to be even worse.

Disclaimer: I have been using LaTeX (mostly XeLaTeX) for over a decade for most of my writing, mathematical and non-mathematical, although nowadays I often do so via Markdown+pandoc. Also, at my last company we had to parse mathematical formulas typeset in LaTeX and understand their structure... it was a nightmare.
