> While this could be done by junior or senior, I think junior usually has the slight advantage in being more AI-native and knowing how to effectively prompt and work with AI, though not always.

But juniors don't (usually) have the knowledge to assess if what the AI has produced is ok or not. I agree that anybody (junior or senior) can produce something with AI, the key question is whether the same person has the skills to asses (e.g., to ask the right questions) that the produced output is what's needed. In my experience, junior + AI is just a waste of money (tokens) and a nightmare to take accountability for.
