When an AI system recommends something and a person acts on it, accountability is straightforward: the person decided. When the system searches, drafts, files, and sends on its own, the decision is distributed across a prompt, a toolset, a vendor's model, and whoever last approved the deployment. Ask who is responsible and you get four plausible answers, which in practice means none.
This is not a theoretical worry for me. Building agentic workflows means watching an autonomous loop do something reasonable-looking for the wrong reason, and realising that no existing document in the organisation says who owns that outcome.
