I'm trying to understand why this comment got downvoted. My best guess is that "if you're in the loop, something is wrong" is interpreted as there should be no human involvement at all.

The loop here, imo, refers to the feedback loop. And it's true that ideally there should be no human involvement there. A tight feedback loop is as important for llms as it is for humans. The more automated you make it, the better.

Yes, maybe I goofed on the phrasing. If you're in the feedback loop, something is wrong. Obviously a human should be "in the loop" in the sense that they're aware of and reviewing what the agent is doing.
