It is beginning to look like the future is treating Rust as an optimization pass. Write your program in a higher-level language like Typescript, Go, Python, etc. and then have LLMs compile that to Rust.
From the OP post it costs tens of thousands of dollars to do that compile.
Not really, the future are natural languages, with some markdown files for formal specification, yaml or whatever, and then Assembly gets generated directly.
3 GLs are going to slowly fade out as LLM tooling improves, and coding looks increasingly as envisioned by 4 GLs advocates.
Just give the LLM requirements and have it output rust. Just like giving a compiler a text file and it outputs machine code.
