I'm not sure either matter to be honest.
It's cool sure, powerful also... but when anybody has access to both vector-based editor and raster-based editor ... but also tools that incorporate them, e.g. rich text editors ... but also entire toolchain going from compilers to libraries all the way to Web based notebook with their editors and running environment that can then output printable artifacts, I don't think there has to be "the" way. They might be a more popular way within a certain zeitgeist but... does one project has to "replace" another one?
I guess I don't really get the passion some people have for "perfect" rendering. I'm fine with just text, then just readible equations below it, then an OK looking graph. I don't actually care if any of those are pixel perfect. I don't get it.
IMHO in terms of actual knowledge transmission reproducibility and interactivity are way more important. They might not look as good and in fact introduce a TON of complexity but I believe it's better than yet another system that is slightly better looking while being slightly easier, for those people with a specific mindset, to setup and use.
PS: still both Gribouille and Typst are cool projects! Just want to make sure I'm not sounding critical against those efforts.
