I've got one. I'm working on a cryptographic identity system in rust. One of the stricter iterations of it demanded creating a public version and private version of each type. The best way to accomplish this is a procedural macro. I don't know if you've written proc macros by hand in rust. I have, years ago, and it was somewhat torturous. I didn't want to relearn to do it all over again and spend what would have taken weeks (this is a side project) to gain a skill I will easily forget in a month or so. So I had an LLM code it for me. This is a really great use for it: it's not building any strong logic or doing any IO, it's simply writing code that generates other code, and is entirely verifiable and testable. It built it for me so I could spend those weeks working on higher level logic and p2p syncing protocol stuff that actually matters for the project.

I want to make it clear that I'm an LLM luddite. I mostly find the things distasteful and obnoxious. But there are definitely use-cases where they can do what's essentially bitch work and save a lot of time that would otherwise be a waste. It's a tool that can be used for specific things. I don't use them for everything.
