Under every single LaTeX themed post there is someone suggesting typst. Why use something open, if you can use something proprietary? /s
The compiler is open source: https://github.com/typst/typst
And maybe because LaTeX is a pain to work and debug? So please don’t tell me that you have never been frustrated with it.
What are you using it for? Did you publish anything written in typst? Edit: this is a genuine question.
