Cut my editing time per article from 4 hours to 90 minutes once I stopped reviewing every paragraph and started spot-checking only the sections where the agent had low confidence scores. The trap was treating myself as a gate on every sentence instead of a gate on the 20% that actually needed a human eye.
We cut first-response time from 40 minutes to under 2 by routing tickets through Intercom Fin, but the trap was letting it close tickets on its own. It started "resolving" billing disputes by confidently quoting the wrong refund policy. Now anything touching money or cancellations gets flagged to a human queue, and the bot only drafts the reply. Two agents review what used to take six people to answer.
verification step still eats more time than the drafting it replaced
The "human in the loop" framing breaks the moment you scale past one reviewer: on my 12-person team, routing every agent action through a person just moved the bottleneck from writing code to approving diffs, and people rubber-stamp at 40 PRs a day. The real choice isn't human-in-the-loop versus autonomous, it's deciding which actions are reversible enough to never need a human at all.
