Free, capable AI tools meeting billable-hour time pressure produce the same result in every firm we walk into: people are already using them, and nobody has written down what's allowed. That isn't a discipline problem. It's what happens when a useful tool arrives faster than the policy governing it.
The professional obligations don't wait for the policy, though. Duties of competence, confidentiality, and supervision of staff apply to AI-assisted work the same way they apply to everything else — and when something goes wrong, the difference between an isolated mistake and a systemic supervision failure is usually whether anything was written down beforehand.
