not sure what’s the point of using/highlighting rust here. low-level language for a high-level application with IO-bound latency.

View on HN

- It is possible to write Rust in a pretty high level way that's much closer to a statically-typed Python than C++ and some people do use it as a Python replacement

- You can build it into a single binary with no external deps

- The Rust type system + ownership can help you a lot with correctness (e.g. encoding invariants, race conditions)

Codex is also in rust, no other modern language can compete. Maybe another older low level language. It's perfect for this kind of application.

I think the point is, what does it add to the discussion mentioning the language it is written in?

This is a rust trait. Titles farm karma like that because "Presenting: myapp" vs "Presenting: myapp written in rust", the latter will receive more attention.
