Typst fixes pretty much every problem LaTeX has.

It replaces the macro language of LaTeX with a python/rust like language, which couldn't be easier to write.

The markup language has a markdown like syntax which makes writing simple things simple. And allows for complex, but easy to comprehend operations when useful.

It has good tooling, with helpful error messages and is not arbitrarily limited on memory or font support. (I know some LaTeX engines do not have that problem anymore, but even the Idea of competing engines with different feature sets is somewhat ridiculous)

I have used it a lot, for many different things.
