The one thing the Typst could do to eclipse TeX is market itself to authors outside of STEM disciplines who still possess a willingness to get their hands techy. I view Typst on the high-end of software that can encourage more people who are into the "arts" or "humanities" into coding. I used it once to typeset a booklet and had a lot of fun. One of the benefits of it being new and having an engaged community and being just fun to use is that I got to explore different workarounds to achieve certain layouts, learning more about how it works along the way. Troff is lots of fun too.
