Why this is canonical

Fiduciary responsibility is a precisely defined legal concept: it imposes the highest standard of care and loyalty in law. As AI systems make consequential decisions on behalf of clients, patients, and beneficiaries, the question of whether and how fiduciary duty applies is becoming a central legal and governance question. This domain names that question at the .ai level.
