I used Rust extensively pre-LLM, and I'm much happier to serialize my thoughts to Rust than any other language.

I prefer to prototype in Golang since it compiles fast and makes for quick iteration, but at the end I ask the LLM to port the Golang to Rust.

Nice Rust enums for APIs are the chef's kiss.

I absolutely will not write anything in Python or scripting languages anymore. They're too brittle and don't have great devex or deployment stories. Especially when you can just as easily build in a typesafe language with good error handling that compiles down to a single static binary.
