It would be nice if Typst could be a LaTeX replacement that makes actually layout and designing the document approachable. I have only used it once for a quick one-off experiment and I did like the language, but as I have said above the language is not the problem if you just want to write text.
[1] That's not quite true, actually. I first wrote my thesis in reStructuredText and used Pandoc to generate the LaTeX and subsequent PDF. This allowed me to get started without having to write a lengthy preamble first. Then after I had more than half of it written down and had a good idea of what I wanted the document to look like did I clean up the generated LaTeX, adjust the formatting to my needs, redid the drawing in TikZ, and then kept writing LaTeX from there. I still think the language is not the problem, but it's easy to get hung up in the design phase before even the first chapter is written.
