I like the comparrison of the AI coding agent to the steak machine. But it is not just about machines scaling better - the laundromat can wash clothes better than a human would. Similarily the AI agent's performance can EXCEED one of a human engineer for simple, well-defined tasks (eg. go over all of the subpages and check that the latest push didn't break something).

Hiring AI cooks is not a problem imo, as long as the human glances over everything that they serve.
