I'm following the progress of this package, I would not mind a more modern successor to LaTeX. I'm an academic, and I actually do not mind LaTeX. I find actually writing LaTeX to be fairly natural. But every time I come to the programmatic interface I feel like there's a lot of room for improvement and that's the most exciting aspect of typst.
I cannot, reasonably, start using this for work until journals begin accepting papers in the format. But I am following until either that starts happening, or some workaround exists.
