In the Loop and Emptied by It

On night shift at GM’s Lansing Delta Township plant, there was no one upstairs in engineering to call. I was a shift leader. When the line went down, and we had eliminated all the Neanderthal mechanical culprits, and what was left was a controls fault, the radio call went out.

When a trim shop stops at fifty-five jobs an hour, a hundred and fifty people stop with it. Fifteen cars sit in the buffer to chassis. In about fifteen minutes they are gone, chassis starves, and two hundred and fifty more people come to a stop. The plant loses at least five thousand dollars of gross margin for every minute it stands.

Within minutes of the radio call, Grace Major would roll down with her apprentice in tow. Calm. Collected. A reassuring smile. She kept me at bay and kept me informed as needed, so I could send people off early on break to save the losses. And she always found a way to get it running. She was like a talisman.

On October 5, 2026, Walter Isaacson published an essay in the New York Times about Ada Lovelace. He names a camp after her: people who want humans and machines as partners, with the human kept in the loop. Then he asks, “Why should we insist that we humans remain in the loop?” Machines alone often do better, he grants, and competition will push people out. His answer is that people need meaning as well as abundance, so we should favor tools that include us.

I agree with where he wants to go. But “in the loop” is too easy a test to pass.

A person can be in the loop and be emptied by it. The test is which way the knowing runs. If the work leaves the person knowing more, that loop is a bloom. If it carries what the person knows into the machine and leaves the person where they stood, it is a siphon. Both have a human in them, and the books record only what went into the machine.

That’s the argument.

What was on the card

Start where Lovelace started. She wrote that Charles Babbage’s Analytical Engine “weaves algebraical patterns just as the Jacquard loom weaves flowers and leaves.” Before Jacquard, a figured silk took two people at the loom: the weaver, and a draw boy who lifted the warp threads by hand. Jacquard’s loom of 1804 read the pattern from punched cards, one card for every pass of the shuttle. The draw boy was gone.

What was on the cards? Someone who knew weaving had worked that pattern out thread by thread. The card held what a weaver knew, in a form that could be copied and carried to a loom the weaver would never see.

Isaacson notes that Lovelace’s father, Lord Byron, stood up in the House of Lords for the Luddites, and he says they were wrong: by the end of the century textiles employed about ten times as many people. The knitters Byron defended worked on machines every day. Their fight was with masters hiring workers who had not finished the seven-year apprenticeship. Two years after his speech, Parliament repealed the old apprenticeship statute.

The jobs came back tenfold. The seven years, the part that ran into the person, did not.

A century after Jacquard, Frederick Taylor did the same to the machinist with a standard work card, and he was plain about why: “All possible brain work should be removed from the shop and centered in the planning or laying-out department.” In Built to Extract, the Card is the first rung of the siphon.

I should say which side I started on. I came to General Motors in 1989 still writing a doctorate on diagnostic expert systems. At Flint Metal Fab we had huge transfer presses with complicated Unico controllers overhead. When a press went down and the electricians were flummoxed, they flew in a man named Jim from Chicago to troubleshoot it. The expert system I called Trades tried to emulate what Jim knew.

I was there to punch the card. Trades died a natural death. Maybe we cut the diagnosis time for a novice electrician. We still hunted through a labyrinthine basement for spare boards and lost the time anyway. And Jim still flew in. I did not dent that expense much. His tacit knowledge was too vast for my cards.

That was 1989. The cards hold far more now, and Isaacson is right that they will hold more every year. That is why the direction of the flow matters more than it did then.

The apprentice

Grace retired while I was there. After she left we were comfortable, because her apprentice had learned the work under her, right in front of our eyes. His name is Malachi Smith. I have watched him show up to a dead line, two hundred and fifty people waiting, with his laptop on a cart. Quiet, composed, competent. Within minutes we were running again, and it looked like magic.

In May 2026 General Motors published a profile of him. Its title is “On the Line: How Curiosity Turned Malachi Smith into a Controls Engineer.” It says he started as a co-op at eighteen and rotated through quality, maintenance and controls. The curiosity is real. So was his teacher. Grace Major was a true teacher and a completely unsung hero. The profile does not name her.

A controls engineer writes the logic the machines run on. On a plant floor, he is the one who punches the cards. The profile asks Malachi where the best ideas on the floor come from. His answer: the people who touch the equipment hundreds of times a day, the team members and electricians who know every quirk of a station. “Our job in controls,” he said, “is to take their insight, add the technical piece, and turn it into a real solution.”

That is the card-puncher’s job, in the words of someone good at it. My test asks one more thing of it: what comes back to the electrician? A record, or a raise? The profile does not say.

It tells one more story. The laser scanners in the final alignment pits kept missing the labels on the windshields, and every time they missed, an operator scanned by hand. Those operators we
