Scaled up slightly, we use it to build plenty of internal tooling in our video content production pipeline (syncing between encoding tools and a status dashboard for our non-technical content team).
Using it for anything more than boilerplate code, well-defined but tedious refactors, or quickly demonstrating how to use an unfamiliar API in production code, before a human takes a full pass at everything is something I'm going to be wary of for a long time.
