mitex is an option [1]. There's no way I could learn another notation, at this point.

I'll only say that learning typst is easier than learning LaTeX.

It also has first class support for unicode (as does LaTeX via some packages) which if combined with a suitable keyboard layout makes both writing and reading math source code infinitely more pleasant :)
