The lesson
A full crew of machines
One night last month, my pub ran a full crew of machines. One took the bookings. One watched the stock. One answered the phone. One planned the delivery runs. Not one of them was a person, and the bowls still came out right. A team of agents with different jobs, passing work to each other. The industry calls it a multi-agent system.
Specialists passing the bowl
Specialists pass the plate. One agent knows the bookings, one knows the kitchen, one knows the suppliers, and each passes its part along, the way a cook, a server and a bookkeeper run one pub. The trick that makes it safe is the fences. Each agent works inside a guardrail. The booking agent may not change prices. The stock agent may not order more than the budget. The phone agent may not promise anything the kitchen has not confirmed. And over every fence stands one more rule: the human. When a decision is big, unusual or hard to undo, the agent stops and calls me. The industry calls it human-in-the-loop.
Where crews already work
Crews already work around you. A bank where one agent checks the payment, another checks the address, another checks the account history, and only then the transfer goes through. A hospital where one agent reads the scan, another checks the records, and a doctor reads both before signing. Same shape: specialists passing work, fences around each, a human at the gate.
Autopilot, or call me?
Three jobs land on the bar tonight. Job one: a regular asks for his usual bowl. Job two: a booking asks to change the date on a party of 20. Job three: the till does not balance at closing. Which job does the crew finish alone, and which two do they bring to me? I give you three seconds.
Pause here for three seconds.

… The usual bowl, alone. The party of 20 and the till, to me.
The crew knows the fence. The bigger the stake, the sooner an agent should stop and call a human. That is not weakness. That is the design.
