I think there is hope though. Grad students are slowly picking it up, and they are the future of academia. I've seen similar transitions away from Fortran and Matlab as grad students embrace different tools than what their advisors use.
my experience is the opposite. Due to LaTeX's arcane scripting and the lack of interest people have in learning it beyond "it compiles on overleaf", I'm seeing a lot of accumulated superstition. People copying and pasting preambles with useless packages, unused newcommands. Worse, people sometimes use their group's newcommands without being aware of the native functions, e.g. \beginmymatrix replacing \begin{pmatrix}. Even if change is slow, any amount of Typst adoption is good.
For next year, I plan to prepare a thesis template for our university and encourage students to try it instead of latex (most of our students use latex now).
It was released in 2023 and became polished enough to use like last year. Yeah, adoption takes time but the technology is significantly better.
> The problem is also momentum. Do you rewrite 30 years' of CTAN contributions, internal templates/styles and the toolchain off and start again or not?
With latex you have to rely on third party. With typst you can write it yourself (or with an agent), like writing functions is not painful in typst.
