The author is clearly building things for the joy of it. If she gets the most joy from Rust, that's what she should use!

Personally, I spent the first decade of my career switching between languages, believing that I should use the best tool for any given job. I spent the last ~five years doing mostly Rust, and I've learned that there's a level of mastery of a language you can never quite reach if you're always context-switching between them, especially a language as “deep” as Rust. This means I write things in Rust that Rust is not the best language for.
