Not my experience. It's junior level coding and maybe senior level advising, but even then only when clearly directed with the right questions and guardrails.

Not my experience. It's junior level coding and maybe senior level advising, but even then only when clearly directed with the right questions and guardrails. As an autonomous thing? Junior at best. That's why I think it's extremely helpful for seniors: with proper guidance, it really boosts your productivity, writing notable parts of the code.
