I think people are kind of kidding themselves here. For Go and Python, two extraordinarily common languages in production software, it would be weird for me at this point not to start with LLM output. Actually building an entire application, soup-to-nuts, vibe-code style? No, I wouldn't do that. But having the LLM writing as much as 80% of the code, under close supervision, with a careful series of prompts (like, "ok now add otel spans to all the functions that take unpredictable amounts of time")? Sure.

Don't get me started on testcase generation.
