Hammerstein's matrix works because armies have rank, evaluation, and consequences. The classification is useful because there's a system behind it that can observe, judge, and act.

But if "stupid" just means can't adapt and repeats what it's told, that's every script and cron job ever deployed. We used to call that automation. Humans can be stupid too, and we don't fire all of them. We put reviews, audits, and liability around them.

AI agents have none of that. A junior dev who breaks prod gets a postmortem. An agent that modifies 50 files gets a git revert. The problem isn't stupidity. It's that there's no structure around it.
