I read about typst a few weeks ago. I no longer make math- or formatting-heavy documents anymore, but if I had had this while I was in university, I would've loved to use it.
LaTeX is nice, but there's some things that are an absolute pain to get right or make them look like you want to.
And just the effort of painting every one of those pixels one by one, it's not like we have some magic tool to fill an image with the same color and call it a day.
