I have been using TeX/LaTeX for ages and today same issues hinder the user experience like multiple decades ago - cryptic error messages, complex pipeline, lack of the proper Unicode symbols support out of the box, and so on.

Nowadays, with Typst existing, it's vital for TeX ecosystem to solve these issues, since none of them are present in Typst. Projects like Tectonic would solve this for TeX, but they lack enough hands and (maybe) financial support.

Otherwise, using TeX only makes sense nowadays only if 1) you already have some templates 2) some features are still missing in Typst 3) you are just forced to use TeX/LaTeX for whatever reason.
