The feature that rearranges the labor market isn’t intelligence. It’s copy and paste, and nobody talks about it because it doesn’t sound like a threat.

Think about what hiring a person actually involves. You find them, which takes months. You pay them, forever. You train them into your systems, your history, your particular way of doing things, and that investment sits in one head that goes home at six and eventually leaves for a competitor. Every good organization is a machine for slowly turning money into a small number of people who know things, and the whole structure of management exists because those people are scarce, expensive, and mortal.

Now do it the other way. Train one capable system on your systems, your history, your particular way of doing things. Then make a thousand of it. Not a thousand trainees who each need the same explanation. A thousand identical instances, each already knowing everything the first one learned, all available at once, all willing to work Sunday. The unit economics of expertise, which have been the same since guilds, break at that sentence. Expertise stops being something you grow one person at a time and becomes something you provision.

Look at what falls out of that. The most expensive thing about knowledge work has always been that knowledge sits in individuals: it has to be transferred by conversation, it decays, and it walks. Copying deletes all three problems in one move. The senior person who knows why the ledger reconciles that odd way in the Spanish subsidiary is currently a risk you manage with documentation nobody reads. In the other version, that knowledge is a file, and every instance has it, and it never retires.

Then there’s the pricing, which is where it gets genuinely strange. A human’s cost has a floor made of rent and food and a life. That floor isn’t negotiable, it isn’t a market outcome, it’s biology and dignity. The cost of an additional instance has no such floor. It’s the cost of the computation, and computation has been getting cheaper for as long as anyone reading this has been alive. So one side of the labor market has a hard floor set by what it takes to keep a person alive, and the other side has a curve that keeps falling. Those two things are not competing on the same axis. They’re barely in the same conversation.

I’m deliberately not going to tell you today what this does to wages. That’s a later part of this series and it deserves its own stretch. What I want you to hold now is only the mechanism, because the mechanism is where the intuitions break and the conclusions come later on their own.

Now the objections, and they’re substantial. Instances aren’t free, and anyone who says they are hasn’t seen an infrastructure bill. Running many capable systems at scale is expensive today, sometimes wildly so, and the energy has to come from somewhere real. Reliability is worse than the demos: a thousand copies of something that’s wrong in a subtle way is a thousand times the wrongness, arriving faster than anyone can check it. And plenty of work isn’t knowledge work at all. Fixing a boiler in an old building requires hands, judgment about a specific rusted thing, and a conversation with the woman who lives there, and none of that is solved by having a million of anything.

Also, and this cuts against my own case, cheaper inputs have historically created more work rather than less. When something gets radically cheaper we tend to want vastly more of it, and the extra demand has always found people to employ. That has been true for two centuries and I’d be foolish to bet against it lightly, which is why a doubt post later in this series takes it seriously rather than waving at it.

But I’d note what’s different in the pattern this time. Every previous wave replaced a task and left the worker holding a different task. The thing about a general system with copies is that when it takes the new task too, there’s no third place to stand, because standing somewhere new was always the escape route and it was always powered by the one thing we had that machines didn’t, which was the ability to learn something else.

Tonight’s exercise, and it’s uncomfortable by design. Work out roughly what your employer pays for an hour of you, all in. Then list what you actually did in your last three working hours, honestly, including the meeting that didn’t need you. Now imagine bidding for that same work against something that already knows everything you know, doesn’t sleep, and can arrive in whatever quantity the job requires. Don’t answer whether you’d win. Answer what you’d have to be offering for the question to even be close.
