The fact that it's Rust should be held against the LLM, no for it. Languages with greater type safety are a massive crutch for LLMs (it's also why using an LLM to manage your NixOS install is pretty fucking awesome).

Make it port some Rust to JS, see how that goes.

And Rust isn't a super difficult language to use on a daily basis. Sure, the initial learning curve is obnoxiously steep, but it's arguably easier to use than other languages once you get past that.

The LLM crowd have this habit of equating something that they don't understand with requiring some kind of advanced skill.
