When AI acts, who signs?
Detailed summarized thinking traces for Claude and ChatGPT are ending, which has made being a human in the loop more challenging, as Ethan Mollick argued in his note on the shift. That matters today because the loss is not abstract. When a system drafts, clicks, edits, uploads, or sends, the visible path between prompt and outcome gets thinner while the human remains the named reviewer.
A second part of the same shift is the product instinct to make the system feel seamless. Hiding thinking traces almost entirely so the AI just does "magic" is being criticized as a move worth challenging, again in Mollick's follow-up. The criticism is not that every internal token must be exposed. It is that work with no inspectable trail leaves accountability in the room but removes much of the material a person would use to check what happened.
The horizon is this month, not some distant forecast. OpenAI is promoting GPT-6.1 Terra as a fast, lower-price model for computer use that understands what's on screen and takes action across apps, according to OpenAI's announcement. Once models are positioned to operate software directly, the old habit of reading an answer and judging only the final text stops being enough. The important unit of review becomes the sequence of actions taken against live systems.
The practical problem is authorship and accountability. If an AI opens a CRM, renames a file, updates a field, copies a number into a sheet, and sends a message, the missing item is not a philosophical window into machine cognition. The missing item is a usable record of what changed, why it was attempted, and where a person should inspect. That is the difference between opaque magic and visible footprints across a desktop.
A prepared person can answer this loss with a narrower demand. Do not ask for every hidden thought. Ask for operational receipts. In practice, that means a short action log attached to any cross-app task: intended goal, tools used, files touched, and state changes made. Those are the pieces a reviewer can reconstruct without pretending to audit a model's full internal process.
This is a better fit for workplace oversight because it matches how responsibility actually works. A manager or analyst rarely needs thousands of tokens of machine reasoning. They need to know what the system tried to do, which applications it entered, what objects it modified, and where the risky step occurred. A compact receipt supports spot checks, rollback, approval gates, and cleaner handoffs between the person who delegated and the person who verifies.
That is also why receipts are a replacement, not a consolation prize. If visible thinking traces are going away while computer-use systems spread, review has to move closer to the action itself. Goals, tool choices, and state changes are inspectable in a way that long generated rationales often are not. They can be compared against the task, the policy, and the result.
This week, ask AI systems that act across apps to return a short action log after each task: intended goal, tools used, files touched, and state changes made. If the model will not show its thoughts, make it show its footprints.
