> Why on earth would you try to rewrite python CRUD apps in Rust?

Because Rust has a lot of incredibly helpful features that make bigger systems far less of a pain to maintain. I work in Java/Kotlin, and my entirely gut-based estimate is that 66% of problems wouldn't happen in Rust.

My big favorites are: - Sane, well-defined, enforced, opt-out error handling - Sane, well-defined, enforced, opt-out handling of "missing" values - Exhaustive switching - WITH usable ADTs (enums) for encoding valid state

None of the web languages I know have all of that.
