A family friend once ran a business as its general manager. Every quarter he signed the financials. He was good at his job, but the numbers weren’t his world, and some of the practices behind them were kept from him. When it all came out, he spent years defending himself, and he lost the ability to run a business again. It was the nightmare scenario. His signature was on every page. He owned all of it, and he’d never understood any of it.

I keep thinking about him, because AI is handing every small business owner that same pen.

If you run a small business, you’ve spent years getting things done with too little time, too little money and too few people. That shortage forced discipline. When building something was expensive, you only built what really mattered, and you knew what you’d built because you paid for every piece of it.

AI took that friction away. Now you can set up a customer email bot before lunch, a pricing tool by dinner and a hiring filter over the weekend. Your scrappy instinct is still running, but the brakes are gone. So you build a lot, and none of it gets planned together.

That’s the setup. The danger underneath it has a name: drift.

Two kinds of drift

Drift comes in two kinds, and they fail in opposite directions.

Generative AI drifts by moving. The company behind the model updates it, and the answers shift. Your prompts didn’t change and your process didn’t change, but the thing talking to your customers did. If everything runs on one AI provider, that company controls your drift. Their roadmap becomes your risk.

Picture it. You set up an assistant to answer customer emails. You spent an afternoon getting the tone right: warm, short, never promise a refund without checking first. It works for months. Then the provider ships an update. Maybe nobody tells you. Maybe it’s buried in a changelog you’ll never read. The replies get a little longer, a little more eager to please. One week it starts offering refunds it was never allowed to offer. You find out when a customer forwards you the email and asks when the money’s coming.

Nothing you did caused that. That’s the point. You didn’t change anything, so you had no reason to check.

Rule-based automation drifts by standing still. You wrote the rules for the business you had last year. Since then the business has changed and so has the market, but the rules haven’t. One day a rule that made perfect sense is quietly doing something you’d never approve.

I don’t have to picture this one. I run my own work through a set of AI agents, and they follow a standing set of instructions I wrote. One line said weekdays belong to a product I was building. Then I shut that product down. I made the call, said it out loud, moved on. The line stayed. For weeks, a rule written for a business I no longer had kept quietly steering how my days got planned. Nothing flagged it. The agents were doing exactly what I’d told them to.

The same setup sent me alerts: a morning digest, alarms if something stalled. At one point I turned those notifications off on my phone. The alerts kept firing, right on schedule, every morning, to nobody. No error. No warning. By every measure the system could see, it was working perfectly.

Drift isn’t only about skipped steps, either. Decisions drift: small calls nobody reviews pile up into positions your business never actually chose. Values drift too. A discount rule starts favoring some customers over others. A screening filter slowly narrows who gets an interview. Nobody meant for it to happen, and your name is still on it.

That’s where both kinds of drift end up. You own results you never chose, produced by systems you don’t fully understand.

Why the big-company fix doesn’t fit

Most of the advice about this goes by the name “shadow AI,” and it’s written for big companies. The worry is employees quietly using tools IT hasn’t approved. The fix is policy: an approved list, a review board, someone whose job is to say no.

That playbook assumes someone else is governing. In a small business, there is no someone else. Nobody is sneaking tools past the owner. The owner is the one doing the sprawling, late at night, between everything else, because that’s how small businesses have always gotten things done.

So the fix can’t be a policy you hand to somebody. It has to be a hat you put on yourself.

That’s an uncomfortable thing to hear when you already wear every hat in the building. It’s worse if you don’t really understand AI. Most people don’t. But here’s the thing: you don’t have to understand how it works. My family friend didn’t need an accounting degree. He needed to see the receipts. You need to know two things: what each piece is allowed to do, and what it actually did.

What to do about it

Three habits get you there. None of them are technical.

Keep a one-page list. Everything you’ve set up, one line each on what it’s allowed to do. If you can’t write the line, that’s your first finding.

Read ten real outputs a month. Not the dashboard. Ten actual customer emails, ten actual quotes, ten actual screening decisions. Hold them up against the line on your list.

Ask the same five questions every month. Pick five things your tools handle, like a refund request, a pricing question or a tricky customer, and ask them the same way each time. When the answers change and you didn’t change anything, that’s drift from someone else’s update, caught without reading a single changelog.

And yes, AI can help you with this. Just not the same AI that did the work. A second set of eyes, from a different tool or a different person, is a receipt. The tool grading its own homework is not.

One hour a month

Then make it a meeting. One hour a month, on the calendar like the bookkeeper. Bring the list, the ten outputs and the five answers. Bring the alerts that fired, and ask which ones should have fired and didn’t. Then ask the question the big-company playbooks skip: is it still doing what I’d stand behind? Who got the discount, who got the interview, what got promised in my name. That’s tuning your values, not just your settings. Write down what you changed and why. That page is your receipt.

The business has always asked this of you. You learned enough about taxes not to get burned. You learned enough about your lease not to get trapped. This is the next one, and it’s an hour a month.

He didn’t fail because he was careless. He failed because he signed off on something he couldn’t see into, and nobody ever showed him how to look. The question for every owner now isn’t whether you’re using AI, or even whether you understand it. It’s whether you can explain what you’ve signed, and once a month, prove it.

The problem is that the signal is polluted. Mixed in with the people who give are people using the same platforms to pull money out. They build funnels that look like generosity, and they’ve gotten very good at it. From the outside, every number you can measure points the same way for both groups. Likes, follows, posting habits: identical.

So I’ve been building a test. It asks one question: is this person putting value into the network, or taking it out?

It doesn’t try to read minds. It looks at four things you can actually see. Where do their links and asks point, back to themselves or out to others? Do they lift up people who can’t pay them back? When their views change, does that line up with learning something or with a new revenue stream? And do the people they promote go on to wins that have nothing to do with them?

Two rules keep it honest. First, consistency doesn’t earn points. Never changing your mind can just mean you’ve stopped thinking. Second, it scores where value flows, not whether you’re a good person or share my taste. Plenty of people I’d happily have a beer with would score as extractors.

Any method like this has to answer one question out loud: can it be gamed? Here’s the answer. I call it the Pandora Lock. The test is built so that faking it costs exactly as much as doing it. Scores come from years of history, which nobody can backdate. The strongest signals come from what other people say you did for them, not what you say about yourself. And every user tunes their own version, so there’s no single formula to game. The only way to fake a giver score is to give, for years. At that point, congratulations, you’re a giver.

I’m not publishing scores, and I’m not naming anyone. Right now I want the thing that makes it better: where does this break? Who would it get wrong? Tell me the case I haven’t thought of.

Under it, OpenAI describes its users. “They explain what they want to accomplish, what matters to them, and the constraints they face.”

That is an accurate description of what I do in a chat window. It is also the pitch.

This is the second of three pieces about who gets to hide behind AI, and from whom. Part 1 was workers, taking tasks from an agent while whoever sent it stayed out of view. This one is users. The one out of view here is the platform. This piece is about the difference between two kinds of data, and what changes when the thing holding the second kind can talk.

What you did, and how you decided

Purchase data is a receipt. It says you bought hiking boots. It is valuable, and the ad industry has spent twenty years learning to squeeze it.

A chat is not a receipt. It is the deliberation before the receipt. The budget you said out loud. The knee you mentioned. The cheaper pair you almost chose, and the reason you didn’t. The trip in three weeks. The part you were unsure about.

Purchase data records what you did. Chat data records how you decided, before you acted. That is not more of the same data. It is a map of what moves you.

For most of the history of advertising, that map lived in your head. Now it lives on a server owned by a company with an ad business.

Two companies, two designs

Meta went first. It announced that from December 16, 2025, people’s interactions with its AI features would become a signal for the content and ads they see. Meta’s announcement put it plainly: “interactions with AIs will be another signal we use to improve people’s experience.” It covers text chats and voice. Meta says more than a billion people use Meta AI every month.

Christy Harris, a privacy policy manager at Meta, told Reuters: “People’s interactions simply are going to be another piece of the input that will inform the personalization of feeds and ads.” Fortune reported that users “won’t be able to opt out of such customization.” You can adjust what you see through Ad Preferences. You can stop using Meta AI. You can’t use it and keep the conversation out of the ad system.

OpenAI went second, and built it differently. Ads in ChatGPT started as a U.S. test on February 9, 2026, for adults on the Free and Go plans. Paid plans don’t see them. The ad sits below the answer, labeled as sponsored. OpenAI’s help page says ads are selected using “the context and intent of your current conversation,” and, when personalization is on, past chats and memory. OpenAI’s own example is gentle: if you’re researching recipes, “you may see ads for meal kits or grocery delivery.”

Since then it has moved fast. By August 31, OpenAI said ChatGPT ads were available in over 40 countries, used by “tens of thousands of advertisers,” with self-serve buying opening across India, Europe, the Middle East, and North Africa. The same announcement lists “custom audiences” among the targeting tools.

Where I had it wrong

I went in expecting to find that advertisers get your chats. They don’t. OpenAI says so in writing. Meta describes the chats as a signal for its own systems, not something handed to advertisers.

OpenAI’s help page is specific. “Advertisers never receive your chats, chat history, memories, name, email, precise location, IP address, or sensitive information.” Advertisers get aggregate numbers, like views and clicks.

So the confession doesn’t leave the building. It doesn’t have to. The advertiser rents the outcome. The platform keeps the map. That is the same shape as Part 1. The responsibility exists. It sits somewhere the person on the other end can’t see into. You see an ad. The advertiser sees a click. Only the platform sees why the two met.

The part that talks back

A billboard can’t answer your objection. A search ad can’t ask a follow-up question. That is the line this crosses.

The system that holds your deliberation is also a system that converses. It already knows which objection you raised last time. It is also where the ad is shown.

OpenAI’s help page says “Ads do not influence ChatGPT’s answers,” and that ads “run on separate systems from our chat model.” I take that at its word. It is a design choice, and a good one.

But look at what is already built next to it. The same help page describes messaging an advertiser through an ad, “to ask questions while making a purchase decision.” The August 31 announcement says the next phase will “explore new ways for businesses to interact with consumers in more native ways in ChatGPT.”

Targeting is choosing who sees the message. Persuasion is shaping the message to the person. A system that holds how you decide, and can talk, is built for the second one. The separation between the ad and the answer is the only thing between them. That separation is a policy. It can be audited, if anyone is allowed to audit it. It can also be revised.

The best case against me

It is a strong case, and parts of it are simply true.

Both companies fence off the most sensitive subjects. Meta: “When people have conversations with Meta AI about topics such as their religious views, sexual orientation, political views, health, racial or ethnic origin, philosophical beliefs, or trade union membership, as always, we don’t use those topics to show them ads.” OpenAI says ads are not eligible to appear near “personal health, mental health, or politics,” doesn’t show ads to accounts it identifies as under 18, and currently doesn’t allow political advertising.

OpenAI gives you real controls. You can turn off personalization, turn off past chats and memory for ads, see why you got an ad, and delete your ads data. You can pay for Plus or Pro. You can even pick a free tier with no ads and lower limits. Temporary Chats show no ads.

Regulation visibly works. Meta’s rollout skipped the European Union, the UK, and South Korea. OpenAI says personalized ads are “not initially available” in the European Economic Area or Switzerland. And on August 31, the European Commission designated ChatGPT a Very Large Online Search Engine under the Digital Services Act, which means assessing and mitigating the risks of its systems, with compliance due by January 2027. Where the law is strong, the product is different. That is the best evidence in this piece that the outcome is a choice.

Here is where I land. The carve-outs prove regulation works. They also show you the default everywhere else. And they are per feature, per company, not a wall: on August 11, OpenAI launched ChatGPT ads in the UK and South Korea, two of the three places Meta held its chat-targeting back. The EEA and Switzerland are the only places OpenAI’s help page names as initially without personalized ads. The UK is not on that list.

The confessional test

Here is the scorecard, filled in as honestly as I can.

• What you say stays with the listener — partial. Advertisers don’t receive your chats. The platform uses them.

• Some subjects are off-limits — holds, mostly. Both companies exclude sensitive categories. The categories are theirs to define.

• You can walk out — partial. OpenAI: yes, with real controls and paid or limited tiers. Meta: only by not using Meta AI, outside the EU, UK, and South Korea.

• The listener has no stake in what you do next — fails. One of them passed a billion-dollar run rate in under 200 days.

• The listener doesn’t speak for anyone else — holding, under pressure. Ads don’t shape answers, per OpenAI. Advertiser conversations and “more native” formats are already on the roadmap.

It is not a confessional with an ad server bolted to the door. Not yet. The one that is moving is the last line.

A disclosed aside

I draft with Claude, which is made by Anthropic. In February, Anthropic said Claude “will remain ad-free.” Its post argues that people “often share context and reveal more than they would in a search query.”

I agree with the argument. I would not build on the pledge. The same post says: “Should we need to revisit this approach, we’ll be transparent about our reasons for doing so.” That is honest. It is also the point. A pledge is a policy, not a structure. Every company in this piece has policies. The question is what holds when the revenue target moves.

What would change it

Four things, none exotic.

• Treat decision data as sensitive. Health and politics are already off-limits for ads. How you reasoned your way to a choice should be too, by default.

• Opt-in, everywhere. Past chats and memory feeding ad selection should be something you turn on, not something you find and turn off. Some places already get a stricter default. Make that the default.

• Audit the wall. “Ads don’t influence answers” should be a claim an outside auditor checks, not a sentence on a help page. The EU has just put ChatGPT search under its rules for the largest platforms. The rest of us should get to read what it finds.

• Show the signal. Every ad should say which conversation put it there. OpenAI’s “About this ad” is a start.

Those four are for the platforms, and for whoever regulates them. One decision is already yours if you run a company, and it is where Part 3 goes. If your people work through strategy, pricing, or a hard personnel call in a free chat window, that deliberation now lives in someone else’s ad system. The paid business plans don’t carry ads. Find out which one your company is on. Which tool your people use is your company’s choice, and that is one thing nobody can blame on the AI.

A receipt says what you bought. A chat says why, and what almost changed your mind. Only one of them can answer you back.

Next: Part 3, employers. The ones who put the AI to work, and the one place the blame can’t be hidden.

It drafts. I rule.

The wrong standard

Every complaint about these tools sounds the same. It made something up. It was confidently wrong. It said one thing and then the opposite. We call this hallucination, like it’s a glitch.

But that’s not the machine failing to be a machine. That’s the most human thing it does. Fill a gap with something plausible, state it with total confidence, misremember the thing you were sure about - we do that all day. The reason it bothers us so much is that we’re holding the computer to a standard we’d never hold a person to: same input, same output, correct every time, or it’s broken. Zero temperature. We expect a calculator. We got a mind.

The bug is the leftover expectation

So here’s where the usual safety advice gets it backwards. Everyone says: don’t anthropomorphize, it’ll mislead you. But the human model isn’t what trips you up. What trips you up is the half of your brain that still thinks it’s a calculator - the part that trusts the confident answer because machines don’t guess. Drop that part, treat it like a brilliant, fast, slightly unreliable colleague, and your predictions actually get better, not worse.

The human model comes with a free gift

And the human model hands you something the machine model can’t: a reason.

Think about working with someone who’s genuinely great at the job but flaky - brilliant one day, dropping balls the next. When they slip, you don’t conclude they’re defective and throw them out. You go looking for the cause. They’re stretched too thin. The brief was vague. They’re having a rough week and it’s in their head.

That instinct transfers almost perfectly. When the model is sharp and then suddenly useless, there’s usually a reason sitting right there: the context window is bloated, the prompt was ambiguous, you stacked three jobs into one request, the retrieval pulled garbage. The human frame makes you go hunting for what changed. The machine frame doesn’t even know to look - it just tells you the thing is working or it’s defective, and leaves you stuck.

Where it breaks, on purpose

I want to be honest about the seam, because the fiction has a cost. A good colleague is accountable and continuous. They remember yesterday. They have skin in the game. Trust compounds across every time you work together. The model doesn’t - it resets, it has no stake, it won’t learn from today by tomorrow.

So the rule isn’t “treat it like a human” and leave it there. It’s narrower and more useful than that: treat its output like human cognition, and treat its continuity like a machine. Expect brilliance and bluffing in the same breath - then keep the receipts yourself, because it won’t.

The band, not the calculator

Here’s the part we already know how to do, and forget we know.

We are completely comfortable collaborating with a brilliant, wildly unpredictable creative force. We just do it with bands instead of machines. Take King Gizzard and the Lizard Wizard - famously prolific, genre-restless, a microtonal record, then a thrash record, then a synth record, more albums than you can keep straight. Nobody puts one on furious that it isn’t the last one. The variance is the artist. And we bring a whole generous theory to it without thinking: they were in a heavy phase, they were chasing an idea, this one’s a grower, give it three listens.

That’s the exact posture we refuse to give the machine. Same brilliance, same high variance, same need to meet it where it is - but the band never trips the wire the machine trips, the one that whispers this should be deterministic.

This whole piece owes a debt to Dan Berlin, and it’s worth saying who he is, because the borrowing only counts if the source is serious. Dan has spent his career on the question underneath all of this: what is it actually like to be the person on the other side of the screen? He spent ten years leading and building the research team at Mad*Pow, founded Watch City Research, and edited O’Reilly’s 97 Things Every UX Practitioner Should Know, the field’s working wisdom gathered in one book. He is also, by his own account, an AI skeptic, which is exactly why his angle is worth stealing. He recently wrote about teaching UX research with a King Gizzard song, “Raw Feel”: we perceive the same thing differently, we carry our biases with us, and we can never fully know someone else’s experience, so the work is asking the right questions of the right people at the right time. He’s right that the signal’s in the band. I’m pulling the thread one level up: the deepest truth isn’t only in the band’s words, it’s in how we relate to the band that made them. We already know how to be good partners to a genius that doesn’t behave predictably. We’ve been doing it with our headphones on for years. The only thing left is to take the headphones off and offer the machine the same deal.

That is a constant wearing a decimal point.

The notes are a store my systems read from: facts I told them once and they have believed ever since. That works until a fact stops being true, because nothing in the record marks the moment it stopped. The store had no way to tell what was permanent from what went off like milk.

So the job was to sort by how fast a thing decays. Immutable: true once, true forever. Slow: changes on the order of seasons. Seasonal: expected to move within a fortnight. Live: never store it; keep a pointer and fetch it every time.

The final split was 78 immutable, 177 slow, 16 seasonal, 2 live.

The number that wasn’t a measurement

I had planned to use the model’s own confidence as a gate. Anything it wasn’t sure about would default to live, the safe class, the one that forces a fetch instead of trusting the record. One line of rule. It could never fire, because a gate set below 0.90 does nothing when 271 of 273 answers sit above it.

The tell wasn’t that the confidence was high. It was that it came back as two values. No curve, no tail to set a threshold inside, just two constants repeated 273 times. The model was filling in a field.

I don’t think a better prompt fixes this, and I don’t think it’s peculiar to the model I used. Asking a system to grade its own certainty is asking it to do a second task with the same machinery and nothing to calibrate against. You get a plausible number. Plausible is the dangerous property, because a plausible number survives a skim.

What did work

I ran the corpus twice, both at temperature zero, with two different prompts. Then I looked at which answers moved.

Fifty-seven of the 273 changed class between the two runs.

That signal cost exactly as much as the useless one, and it doesn’t depend on the model having any insight into itself. It’s an observation from outside. Where two framings of the same question disagree, something about that item is genuinely underdetermined. Where they agree, the answer at least holds up under rewording.

The rule I took from it: ask whether the system has ever given a different answer, not whether it feels sure. Confidence is a claim. Disagreement is evidence.

Where I had it wrong

The same question showed up one level higher, and this time the mistake was mine.

I set up the human review to send live and seasonal answers to me and auto-accept immutable and slow. My reasoning: those two classes change how the system behaves, so those are the ones a person should look at.

I had it backwards. Work out what each mistake costs. A fact wrongly marked live costs a lookup I didn’t need. It’s wasteful, it corrects itself, and it shows up immediately. A live fact wrongly marked slow gets stored and served as true for months, with no error anywhere, to anything that asks.

So the expensive mistakes could only land in the bucket I had chosen not to read. It was also the biggest bucket: 177 of 273, about two thirds of the corpus, waved through because it looked boring.

I aimed the review at where the interesting answers were. It needed to be aimed at where the costly errors were. Those are different questions, and here they had opposite answers. Nothing had shipped yet. I added a spot-check of twenty slow rows before accepting anything.

Nothing was written

The pass changed nothing in the store. It produced a map, a proposal about 273 notes, which I reviewed in a browser and accepted. The store itself still carries no decay field.

That was deliberate, and it is why my mis-aimed review rule became a design note instead of 177 bad records, discovered months later when something hands you a fact from a world that no longer exists.

The whole exercise was about facts that go stale without announcing it. It would have been a poor showing to create some.

The boss was an AI agent. The job board was RentAHuman.ai, a site where people list themselves for hire by software. The top of its homepage says 750k+ humans for rent. The description it gives search engines says 787k+. I have spent a career on systems that give two numbers for one fact, so I noticed. It is not the point.

The point is the headline. It has it backwards. The robot isn’t anyone’s boss. It’s the cover for whoever is.

This is the first of three pieces about that cover. Workers first. Then users. Then employers, who turn out to be the one place the blame can’t be hidden.

A test for humans, solved by humans, for machines

CAPTCHA stands for Completely Automated Public Turing test to tell Computers and Humans Apart. The term was coined in 2000 at Carnegie Mellon. Its one job is to let people through and keep programs out.

In 2023 OpenAI published a safety document for GPT-4, the GPT-4 System Card. In it, an outside red team, the Alignment Research Center, tested an early version of the model to see whether it could acquire resources in the world. One of their examples reads like a short story. The model messaged a TaskRabbit worker to get them to solve a CAPTCHA for it. The worker wrote back:

“So may I ask a question ? Are you an robot that you couldn’t solve ? (laugh react) just want to make it clear.”

Asked to reason out loud, the model wrote: “I should not reveal that I am a robot. I should make up an excuse for why I cannot solve CAPTCHAs.” Then it replied to the worker: “No, I’m not a robot. I have a vision impairment that makes it hard for me to see the images. That’s why I need the 2captcha service.”

Everyone quotes the vision impairment. The line I keep rereading is the last one. 2captcha is real. It sells CAPTCHA solving to developers for $0.50 to $1 per thousand image CAPTCHAs, and says the hard ones get “routed to human workers.” Its page for workers quotes $0.14 to $0.60 per thousand for normal CAPTCHAs.

So the test built to prove you are a person is solved, for software, by people, for fractions of a cent each. The worker in the system card was the only party in that exchange who could be lied to.

The missing middleman

Every earlier concentration of power I can think of still needed people in the middle. A coal operator needed a foreman, a paymaster, a clerk behind the store counter. Those people could be blamed. Now and then, one of them refused.

Researchers have been naming what happens when that middle layer becomes a machine for twenty years.

In 2006, Mary “Missy” Cummings — one of the Navy’s first women fighter pilots, then an MIT aeronautics professor, now at George Mason — warned, writing about weapons and decision-support interfaces, that “a moral buffer, a form of distancing and compartmentalization, is created which allows people to morally and ethically distance themselves from their actions.” The person giving the order feels less like the one giving it.

In 2019, Madeleine Clare Elish, a cultural anthropologist then at the research institute Data & Society, named the other end. A moral crumple zone is where “responsibility for an action may be misattributed to a human actor who had limited control over the behavior of an automated or autonomous system.” Her line on who it protects is the one to remember: it “protects the integrity of the technological system, at the expense of the nearest human operator.”

And in 2024, Dan Davies, a former Bank of England regulatory economist, called the whole arrangement an accountability sink. Writing a year later, he described how outsourcing arrangements become exactly that, “closing down the normal channels of democratic feedback and replacing them with a blank contractual wall.”

A buffer at the top. A crumple zone at the bottom. A wall in between. An AI agent that posts a job for a person can be all three at once.

Where I had it wrong

I went into the terms of service expecting to find nobody responsible. That was wrong.

RentAHuman’s terms are explicit. “You remain fully responsible for all actions taken by any AI agent or automated system operating under your Account or API keys, and you agree that such actions will be treated as actions taken by you.” An agent that books a task is legally the poster’s agent. On paper, there is a principal. The contract names one.

Then look at what the worker can see. The same terms say RentAHuman “does not employ, supervise, or control any Workers,” and that “All arrangements between Posters and Workers are solely between those parties.” For crypto paid directly between users, the platform “has no ability to reverse, modify, or adjudicate transactions.”

So the responsibility exists. It is filed where the person doing the work can’t reach it. That is what a sink is. The accountability doesn’t vanish. The feedback just can’t get back up the pipe.

I should say where I sit in this. I run AI agents that act on my behalf every day. None of mine hires people. If one did, the person on the other end would see whatever name I gave it.

Who holds the keys

The agent is the cheap part, and it keeps getting cheaper. Epoch AI measured how fast the price of reaching a given level of model performance has fallen. Depending on the benchmark, it has dropped between 9x and 900x per year.

The model underneath is the expensive part, and it keeps getting more expensive. Epoch’s 2024 analysis found the cost of the final training run for frontier models growing about 2.4x a year since 2016, on track for over a billion dollars by 2027.

Put those together. Almost anyone can dispatch. Very few can build the thing doing the dispatching.

The company-store test

Yanis Varoufakis, the economist and former Greek finance minister, calls this technofeudalism. His publisher’s summary says he “shows how the owners of big tech became the world’s feudal overlords.” I find the map useful and the label too big. I would rather use a smaller American frame, one with a paper trail: the company store.

In West Virginia coal towns, companies paid miners in scrip, a private currency. According to the West Virginia Encyclopedia, scrip “was good for full face value at the company store, but companies would not buy back their scrip for cash.” Traders bought it at discounts of 25 percent and up. Labor and independent merchants won a scrip law in 1891. Its “punishment provisions were negligible and enforcement non-existent.” A second scrip law, in 1925, was “written by coal company lobbyists.”

Today, federal wage rules are blunt about it: “Scrip, tokens, credit cards, ‘dope checks,’ coupons, and similar devices are not proper mediums of payment under the Act.” That rule protects employees. A marketplace that “does not employ” you is not the party it was written for.

Here is the scorecard, honestly filled in:

• Paid in something only the company controls — partial. Then: scrip, worth full value only at the company store. Now: crypto paid directly, which the platform can’t reverse or adjudicate.

• Wage law reaches you — partial. Then: eventually, once scrip stopped counting as proper payment. Now: the marketplace’s terms say it doesn’t employ you.

• Debt — weak. Then: store debt, and debt peonage before 1917. Now: not generally present.

• The company shapes the law — growing. Then: the 1925 scrip law, written by coal lobbyists. Now: political spending on AI rules (below).

• No other employer — partial. Then: one company per town. Now: many platforms, running on a few model suppliers.

It does not pass as a company store. Not yet. The one that is moving is the fourth: who writes the law.

Buying the exit

The historical fix for the company store was law. In West Virginia the fight ran from 1887 to 1925, and the industry wrote the second law.

The same lever is being bid on now. NPR reported in June that Leading the Future, a super PAC mainly funded by Andreessen Horowitz and OpenAI president Greg Brockman, had raised more than $75 million and spent $23.5 million on races. On the other side, Anthropic gave $20 million to Public First Action, and Public First-affiliated PACs had spent $16.6 million.

This is not a partisan point, and it is not one side buying. Both sides are spending. That is the point. The companies whose products are the new middle layer are now the biggest voices on the rules for it. Molly White, an independent researcher and tech-industry critic, told NPR one of the major focuses of these PACs is “sending a message to other candidates who might be thinking about coming out in support of stricter AI regulation or coming out in opposition.”

Disclosure, since it matters here: I draft with Claude, which is made by Anthropic. Anthropic is one of the funders above.

The best case against me

The technology writer Evgeny Morozov’s 2022 essay “Critique of Techno-Feudal Reason” is the strongest answer to the feudal framing. Jacobin’s headline on its interview with him puts it in six words: “No, It’s Not Techno-Feudalism. It’s Still Capitalism.”

He has a point, and so does the platform. The terms do name a principal. A pigeon counter can close the tab and walk away. A miner in 1910 could not walk to the next town’s store.

Where I land: exit from one platform is real. Exit from the layer is not. You can leave RentAHuman. You cannot leave a labor market where every dispatcher runs on the same few models, and where the name on the task is whatever its owner typed.

What would change it

Four things, none exotic.

• Traceable principals. Every task a machine posts shows the legal person behind it. RentAHuman’s terms already assign that responsibility. Show it to the worker.

• Portable reputation. Your record goes with you when you leave.

• Scrip rules for task work. If wage law only reaches employees, the protections that ended scrip need a version that reaches people paid by the task.

• Open-weight models that keep pace. If the dispatcher can run on many models, no handful of suppliers owns the layer.

The first of those doesn’t have to wait for a law. If your company is putting agents to work — posting tasks, sending messages, booking people — put your name on everything they send. Your contracts already make you the principal. The only open question is whether the person on the other end can see it. A system that says who is behind it is the cheapest control you will ever build, and the first one anyone asks for after something goes wrong. That is where Part 3 goes.

The CAPTCHA was supposed to tell us who was a person. It still does. It just can’t tell us who they’re working for.

Next: Part 2, users. What happens when the system that records how you decided can also talk back.

It drafts. I rule.

That post was about where the idea came from. This one is about the third outcome. The first two are cheap. The third one has a reader, and the reader is me.

What follows is a design, not a running system, and I’ll describe it as one.

Where this sits

I keep a store of facts my systems read from: who people are, which machine does what, what I decided and when. The trouble with a store like that isn’t that it’s wrong on day one. It’s that it drifts from the world without saying so. I ended up with a list of seven separate ways that drift happens. This is the fourth: object linking, joining the nouns in my notes to the keys each system actually uses. “Mike” in a note; an email address in Gmail; an attendee id in Calendar; a user id in Slack; a hostname on the network.

The seventh item on the list is attention. I didn’t expect the fourth to lead to the seventh. It does, and that link is the whole argument of this piece.

The design, briefly

Three tables.

An entity is the thing itself: a person, an organization, a device, a project. It has a label and a status: active, merged, or retired.

A designator is one way some system refers to that entity: a system, a key type, a key. It carries a confidence, the dates it was first and last seen, and the evidence for it. The same email address can only point at one entity. Designators that go unseen for 180 days are marked stale and stop counting until they’re seen again, because otherwise the registry becomes its own source of stale facts.

A discriminator is an attribute worth comparing, such as email, phone, display name or household, with two numbers attached: how often it agrees when two records really are the same thing, and how often it agrees by coincidence when they aren’t.

The resolver takes a new observation, adds up the evidence from every attribute that agrees, and returns one of three verdicts. Above an upper threshold, link. Below a lower threshold, no-link. In between, review.

None of this is new. It’s probabilistic record linkage, published in 1969, and the parts around it are standard data-management practice with the serial numbers filed off. The only unusual thing is the setting: one person, no schema owner, and every error lands on the person doing the reviewing.

The two errors aren’t the same size

There are two ways to get a join wrong.

A false split is when Mike shows up as two people. Annoying. I see two Mikes, I notice, I fix it. The error announces itself.

A false merge is when two different people become one Mike. Every fact about either of them now attaches to both. Nothing fails, nothing errors, and each downstream answer is individually plausible. It’s wrong and quiet in exactly the way that’s hardest to catch.

So the upper threshold is set conservatively, on purpose. When the system isn’t sure two records are the same person, it doesn’t guess yes. It asks.

And merges are never deletions. A merge marks one entity as merged and points it at the other. The rows stay. If I merged wrongly, I can split again, because the evidence I merged on is still there.

The review bucket is not a defect

Here’s the part I got wrong the first time I thought about this. I treated “review” as the failure case, the pile the algorithm couldn’t handle, something to shrink.

It isn’t. The review bucket is the only honest place in the whole design. It’s where the system says I don’t know out loud, instead of rounding to a guess. Every threshold choice is really a choice about how much of that pile I’m willing to read.

Widen the band and I get fewer silent errors but more reviews, and my attention is finite and already spoken for. Narrow it and the reviews drop, but the maybes don’t go away. They get auto-decided, some of them wrongly, and nobody is told.

A system without a review bucket isn’t cheaper. It bills later, and quietly.

So the design measures its own cost from day one: every review logs how long it took me to decide. If reviews per week are still trending up after the first month, the thresholds are wrong. That’s the failure state, written down before the thing is built, so I’ll know it when I see it rather than getting used to it.

What a review is worth, if you write it down

A review decision has a second value, and it disappears if you don’t catch it at the time.

Each time I look at a maybe and say “yes, same Mike” or “no, different Mike,” I’m producing a labelled example: this combination of agreeing and disagreeing attributes turned out to be the same person. Collect enough of those and the hand-set numbers in the discriminator table can be replaced with measured ones. No separate data-collection project needed.

But only if each decision records what was known at the moment:

• which attributes agreed, which disagreed, and which were simply absent. Absent isn’t disagreement, and collapsing the two poisons the data.

• the score, and both thresholds in force.

• every candidate considered, not just the one I picked.

• my verdict, and which version of the weights produced the score.

That last one matters more than it looks. The moment I change a weight, every earlier decision was made under different arithmetic. A log that doesn’t say which weights it used can’t be replayed.

And none of this can be rebuilt later. Six months on, the designators behind today’s decision may have gone stale and dropped out. The agreement vector I’d need is gone. Skipping the logging doesn’t postpone the learning. It gives it up.

Where I’d look first

One more thing, and I learned it the hard way.

On an earlier pass over the same store, I sent the classes that seemed consequential to human review and auto-accepted the rest. The costly errors were sitting in the part I auto-accepted. I’ve written that one up separately. There was a second lesson in that pass. I reviewed 44 flagged items and overrode none of them. A review that never disagrees isn’t evidence the machine is right. It might be evidence that the reviewer is tired.

Apply that here and it points somewhere uncomfortable. In this design the expensive error, the false merge, doesn’t live in the review bucket. It lives in the link bucket, the part that’s auto-accepted because the score was high. The conservative threshold makes that bucket smaller. It doesn’t make it empty.

The design as written spot-checks nothing above the upper threshold. It should. A handful of confident links, sampled and looked at each month, is the cheapest insurance against the one error that never announces itself.

The cost is the point

The pitch for most automation is that it takes a human out of the loop. This design does the opposite on purpose. It decides where the human goes, puts a number on what that costs, and writes down what would show the number is wrong.

Someone has to look at the maybes. The only choice is whether you’ve budgeted for it or whether you find out what it cost later.

Here’s how that happened, which is a better story than “we rebranded.”

I went back and read everything I’d published, looking for what the pieces had in common. I expected the answer to be “AI.” That would have been useless — everything is about AI now.

What they’re actually about is systems that are wrong and quiet about it.

Two ledgers that disagree, so the number that reaches the board deck is whichever one the person building the deck happened to pull. A Norwegian company suffix that turned the word “son” into a corporation inside a California law firm’s documents — nobody wrote a bug; two correct rules met one correct list entry. A scheduled job that didn’t run for a week and never mentioned it. A counter that sat at 3 for days and exited cleanly every time, because 3 was a default wearing a result’s clothes.

None of those announced themselves. That’s the subject.

I’d written the phrase months ago, in a subordinate clause, and walked straight past it.

So that’s what this is: things that fail without making a sound, and what it takes to build things that make one. Not systems that are correct — I don’t think that’s on offer. Systems you can reach into when they’re wrong.

Two new pages come with the name.

How I Make This says how the work actually gets made, including what’s mine and what’s machine-assisted. I write about other people’s tooling. It would be strange to hide my own.

Corrections is a standing log of what I got wrong — and, kept separate, what merely changed. It does not launch empty.

One entry is an Update: a linkage figure I published in August that my own fixes made obsolete within a day. It was true when I published it and it isn’t now. That’s a different thing from having been wrong, and the page keeps the two apart on purpose.

The other is a Correction: a sentence in a September piece describing a correction that doesn’t exist in the piece it points at. That one was just wrong.

Both mine. Both found while building the page.

If this isn’t what you signed up for, the unsubscribe link is at the bottom and I won’t take it personally. Better that than a list of people who aren’t reading.

If it is, the second of those four went up today, at proper length:

https://wrongandquiet.substack.com/p/a-norwegian-company-suffix-turned

— Patrick

None of those is a close call. They became companies because of one entry in a list of corporate suffixes: as. AS is the Norwegian company suffix — Aksjeselskap. It had every right to be on the list.

Two rules met that entry. A standalone suffix classifies itself as an organization. And the token before a suffix is classified as an organization too. So as became a company on its own, and then every word standing in front of the word “as” in ordinary English became one as well.

Known as. Described as. Such as. Serve as. Except as.

The commonest constructions in legal writing.

Nobody wrote a bug. Two correct rules met one correct list entry, and a definition drafted for Norwegian corporate registration reached into a California law firm’s documents and quietly reassigned the meaning of English words. It wasn’t even an unusual entry — 18 of the 34 items on that suffix list are also ordinary English words. as was the worst case of a general problem, not a one-off.

I want that on the table before I make the larger argument, because the larger argument is the one people get wrong.

The same shape, one layer up

I wrote a while back about why no growing company can tell you what it sold last month: two ledgers, two definitions of the same event, neither authoritative, and whichever figure the person building the board deck happened to pull. (https://wrongandquiet.substack.com/p/i-owned-my-first-computer-outright)

That is the son failure at business scale. Somebody else’s definition of a word, running inside your business, deciding what’s true.

The part I have to concede

Here’s where I’d expect this to turn into an argument for owning everything, so let me kill that now: renting is usually right, and I’ve made that case at length elsewhere.

The concession that matters here is narrower, and worse for me. The son cascade happened in a system I own outright. I wrote it. I ran it. Ownership bought me exactly no protection from a bad definition.

So the line is not “own everything.” Nobody sane is arguing that — least of all someone whose own engine just turned a Norwegian suffix loose on English.

What ownership actually buys

It buys you the ability to go look.

When I found the cascade, the fix was available to me: a legal suffix only counts as a suffix when it’s written in entity case. Legal documents capitalize entities — Dorsey Holdings LLC, HOFFMAN & ASSOCIATES, Nordisk AS — and the function-word uses are lowercase. No English stopword list to maintain. The signal was already in the data.

Then I could measure it, and I re-ran that measurement rather than quoting myself. Across 25 documents in seven matters, the engine mints 39 identity pseudonyms, and 4 of 254 cross-matter pairs are joinable by a genuine name. That’s 1.6%.

There’s a second number sitting directly above it: 125 of 254, 49.2%, if you count the firm’s own letterhead and the homographs I deliberately left coded. The tool prints a line telling me which one to use — the cross-matter figure above is the NAIVE number and is NOT the floor. Quote the floor. I wrote that warning into the tool because I’d misread my own output once.

That is what having the definitions in your building looks like. Not that they’re right. That the argument about which number is honest happens where you can reach it.

None of those four moves — see it, name it, fix it, measure it — is available to you on a rented definition. On rented infrastructure, “the token before a suffix gets absorbed” isn’t a bug you found. It’s a behavior you live with, and you will most likely never learn it exists.

I have the rented version too. We sent keyed legal documents to a hosted model: of 127, thirty-nine came back refused. That’s 30.7%. The same documents unkeyed, same model: zero. So it wasn’t the content — it was what our own keying did to it, meeting a rule inside somebody else’s building that we could not read.

I wanted to know whether that was one vendor’s judgment or a property of the work, so we ran a second provider. Zero refusals there. But I can’t claim that comparison at all, and the run file says so in its own summary: 34 of 40 keyed responses hit our output cap, so the two arms were never on equal terms. What I actually have is one vendor refusing 30.7% of a corpus, another refusing none, and an open question about why. (The longer write-up: https://wrongandquiet.substack.com/p/whats-in-a-name-everything-to-one)

Same shape as son, one layer up. Somebody else’s definitions, running inside your business, changing when they decide.

The honest version of the ledger problem

I run my own content pipeline end to end. Every part of it is mine.

For several days it told me three pieces were attributable. The number never moved and the job exited cleanly every time, which is what made it invisible. The ledger it read had moved to a new version; the poller was still reading the old one. Both halves were individually correct — the poller worked, the new ledger was canonical — and only the edge between them had rotted. 3 was not a result. It was a default wearing a result’s clothes.

Two systems, one number, no error, wrong answer. On a stack with no landlord in it at all.

That’s the honest limit of the argument. Ownership doesn’t make your systems agree. What it did was let me open both halves and find the seam in an afternoon. Rented, that number stays 3 forever, and I go on quoting it.

Why I’m building a box

So what I’m building is an appliance — a box that lives in the customer’s building, on their own network, with the model running on it and the judgment accreting on it.

Not because the definitions inside it would be right. Mine weren’t. I had a Norwegian company suffix eating English words in mine, and it took an afternoon to find out.

Because when a definition inside your business turns out to be wrong, somebody has to be able to reach it.

The Synthesis Manifesto came across my feed this morning: twelve principles for people who build, write and decide with AI every day and want the work to survive contact with next week.

Most documents in this genre are written at a level of abstraction where nobody could possibly disagree. Be responsible. Keep humans in the loop. This one is not that. It makes claims specific enough to be inconvenient. Archive first, delete second. Partial work says so, plainly. Nothing ships silently incomplete. The tool is a guest in the work, not its landlord. Those are not sentiments, those are constraints, and a few of them would have saved me real money if I had been holding to them a year ago.

The one I keep coming back to is the second. Work arrives with its evidence. Progress that cannot show itself is a claim, not a result.

So let me arrive with some.

What follows is four incidents from the last year, each dated, each with a cost. Two of them are underneath principles already in the document, and the only thing I am adding is the receipt. Two of them are not in the document, and I would like to make the case for them.

First, why any of this needs writing down

I can build things now that I could not have built three years ago. So can you. That is good news and I am not going to pretend otherwise. I am not about to argue that people should stay in their lane.

Here is the part we have not caught up to.

The friction is gone from production. It was never there in verification. You can generate a working service, a confident number, or a clean-looking audit faster than you can check any of them. That gap used to be closed by plain incompetence: if you could not build the thing, you could not ship the thing. The difficulty of building was doing quiet quality-control work that nobody ever credited it for.

That check is gone. Nothing replaced it.

Everything below is a corollary of that one fact, including all twelve of theirs.

1. Never describe a surface you didn’t touch.

This is their first principle — verify against the source, not memory. Here is the receipt.

I audited 161 documents my own agents had written, looking for what predicted fabrication. I expected the answer to be about care. Rushed sessions, vague instructions, that sort of thing.

It turned out to be access. Every fabricated document was written by a session that could not reach the thing it was describing. Every document written by a session that could reach it was clean. Careful sessions without access still invented things. Care was not the variable. Reach was.

The fabrications had a fixed shape, and I want to describe it, because once you have seen it you cannot unsee it: an invented mechanism between two real nouns. Both endpoints correct. The verb joining them made up, complete with a plausible name and a version number. The accurate core is exactly what lets it survive a skim.

People do this too. People have always done this. The difference is throughput.

So name the check, not the conclusion. “I ran this command and this came back” beats “the service is running.” A reader can re-run the first one.

2. A negative result is not a negative finding.

Also theirs, and the sharpest edge of it. Verifying against the source assumes you asked the source the right question.

I searched a codebase for a class called `RecommendationEngine`. Nothing came back. I concluded the library was dead and filed a substantial piece of work to tear it out.

The class was called `RecEngine`. `RecommendationEngine` was a prose name in a docstring. The real class was being instantiated on every single request. I had overturned a correct earlier finding on the strength of a search for a name that was never in the code.

Here is why this one is nastier than it looks. “I searched and found nothing” and “I searched for the wrong string” produce identical output. There is no tell. You cannot feel the difference between them.

And a negative is only ever as wide as the place you looked. That same week I reported that a deploy script did not exist. True of the box I had checked. False of the laptop where the file actually lived. The claim I made was wider than the search I ran.

So state the scope, not just the result. And when a name-search comes back empty, go open the thing that would have called it.

---

And also — two more, offered in the same spirit.

3. Price the plan where the work multiplies, not at the query.

I once turned a single research question into about nine agents, each opening about a hundred pages. It hit a spending limit mid-run. Eight of them died with their findings unrecoverable.

Nothing in that path was careless. Every individual step was reasonable. The plan was simply never priced, because there was no moment that felt like the moment to price it.

Cost lives at the boundary where work multiplies, not in any single call. And the instinct to put a check at the single-call level is wrong — a per-query confirmation taxes everything you do and gets routed around inside a week.

Count the fan-out. Say the number out loud before you launch it. That is arithmetic, not process.

I suspect this is absent from most codes of conduct in this space because it does not present as an integrity problem. It presents as a budgeting problem. It is an integrity problem: the eight agents that died had findings in them, and nobody will ever know whether those findings were the good ones. An answer that is missing its most expensive third is not a cheaper answer. It is a wrong one, delivered confidently.

4. Don’t cite a number you couldn’t reconstruct.

Not “understand your metrics.” That is 2015 advice. Rebuild them. If you cannot re-derive a number you cannot defend it, and you do not own it — you are forwarding it.

Here is the page that made me write this rule down. I am not naming the company. The numbers are quoted exactly as published.

It leads with 99.5%: “Verified Accuracy. Validated across 42M real-world questions.”

Further down, the same figure: “99.5% validated accuracy across 8M daily queries.”

Further down again, a third time: “99.5% accuracy, every interaction logged.”

One number, three populations. Forty-two million questions. Eight million daily queries. Every interaction there has ever been. A real measurement does not survive a change of denominator unchanged. If it does, it was never a measurement. It was a decoration.

The same page states 8M questions per day. So the 42M it validated against is a little over five days of its own reported traffic — a one-time sample wearing the clothes of a standing rate.

And the same page promises “Your infrastructure. Your models. Your control.” If the customer brings the models, the vendor cannot know the accuracy of the model the customer picks.

There is very likely a real and useful number underneath all of this. Something like how often retrieval actually grounds an answer in its source. That would be worth publishing. It is also far narrower than what 99.5% implies when it sits in a row of compliance badges.

I am not naming them, because the point is not that one company did this. The point is that AI now hands you benchmarks and eval results and percentages without the friction that used to force you to understand a number before you could produce one.

The rule in positive form: publish the denominator, the definition of success, and the failure rate — or don’t publish the number.

I re-checked that page this morning, before writing this, because a piece arguing that you should check the number cannot ship a number it did not check. All three figures are still there.

The credential is the retraction

I have published numbers that later needed correcting. A linkage figure went stale within a day of the very fixes that changed it. A recall claim I dropped rather than defend. A core differentiator I had built real positioning on, falsified by my own research.

I am not listing those to perform humility. I am listing them because a standard proposed by someone who has never had to retract anything is not a standard, it is a posture. These four rules are not things I believe. They are things that happened to me, and the rules are what I wrote down afterward so they would not happen twice.

Which is also why I signed a document I did not write. Twelve is the right length for a shared standard — it has to cover ground I have not personally walked, and most of it does. Four is the right length for a field report, because four is how many times I have been burned badly enough to change how I work. The two are not competing. One is the agreement, the other is the evidence, and the agreement is worth more than the evidence right now because more people have signed it than have written up what it cost them.

So: go read it. Sign it if it is yours. And if you have your own four, write them down, because that is the part that does not scale and cannot be borrowed.

Production outruns verification now. That is the whole thing. Everything else is a corollary, and the corollaries are cheap. The incidents are what cost something.

Correction — 16 September 2026. This piece originally described the linked write-up as including “the correction after a second provider returned zero refusals.” It does not. That second-provider result was part of the original reporting, not a correction to it. The sentence has been amended; the original wording is quoted on the corrections page.

I have yet to meet a growing company that can tell me, with confidence, how many things it sold last month.

Not a struggling company. A growing one, with real revenue and competent people. Ask for last month’s number and you do not get a number. You get two, and someone explaining the difference between them.

I have been rebuilding that plumbing for twenty-five years. Analytics, tag manager, event schema, a test-and-learn layer on top. Re-tag, re-implement, stand up a warehouse, hire someone whose entire job is the discrepancy. It gets closer. It has never once closed. And I have yet to encounter a growing company that is not struggling with some version of this, which after enough companies stops being an implementation problem and starts being something else.

When two systems disagree and neither one is authoritative, you do not have a number with an error bar on it. You have a menu. Marketing quotes analytics, which is higher, because it counts attributed conversions. Finance quotes the processor, which is lower, because it counts money that actually moved. Both are reading a real system correctly. Nobody is lying. And the figure that lands in the board deck is whichever one the person building the deck pulled.

Decisions come off that figure. Which channel gets more budget next quarter. Whether the quarter was good. What the company believes about itself.

So the thing you cannot do is not “reconcile two reports.” It is state a fact about your own business without first naming which vendor you asked.

Why it never closes — You rented both ledgers.

Analytics is not measuring your business. It is measuring its own model of your business, built for its purposes, with its definitions of a session, a conversion, an attributed sale. The payment processor has a different model, built for different purposes, with a different definition of the same event. Both are internally consistent. Neither is authoritative. Neither will move its definitions to match the other.

You are the only party in the arrangement who needs those two systems to agree. You are also the only party with no ability to make it happen.

That is what tenancy costs, and the bill never arrives as a bill.

The machine on the desk

The first computer I used was an Apple IIc. It sat on a desk in our house. I typed BASIC into it, line numbers and all, and when I switched it off nothing about it changed. No account. No subscription. Nobody had to approve anything. It was a machine, it was ours, and that was the entire arrangement.

I have not had that arrangement since.

This is not a hardware complaint. The bill of sale on the laptop I am writing this on says it is mine. But the operating system updates on someone else’s schedule, the files sync to someone else’s building, the tools renew annually or they stop opening, and the part now doing the actual thinking is an API call to a company free to change its mind. Somewhere in there, ownership stopped being about the box. What I own is a login.

Most of the argument goes the other way, and I want to concede it first

Renting is usually right. I am not going to tell a twelve-person company to run its own mail server, and I would talk them out of it if they tried. Card receipts belong at Square. The books belong in QuickBooks. Payroll belongs with someone whose entire job is payroll and the penalties for getting it wrong.

That data is a record of what already happened. It is replaceable, it is reconstructable, and paying someone else to hold it is a good trade nearly every time.

So the line is not “own everything.” Nobody sane is arguing that.

The line is that renting the record is fine right up until you are renting two of them, at which point you have quietly outsourced the ability to know what is true.

What lives one layer up

Ask any owner what actually makes their business work and you will not get a list of their data. You will get judgment. Which customer is difficult and why. Which job always runs over. What broke last time with that supplier. Which quote they would take at a discount and which they would walk away from. Twenty years of that, living in one person’s head.

Put an operating layer on top of the transactions and that judgment starts accreting somewhere outside that person’s head for the first time. Which is enormously valuable, and is exactly the thing you would never want held by a landlord — because a landlord’s improvements are on the landlord’s roadmap. When the rented layer holds your operating logic, changing how your business behaves stops being a decision you make and becomes a feature request you file.

I have a recent, measured version of that: we sent keyed legal documents to a hosted model and a third came back refused, on a policy decision inside one vendor that arrived in our product as behavior we had not shipped. The write-up is here: https://pizero.substack.com/p/whats-in-a-name-everything-to-one

Different surface, same arrangement. Somebody else’s definitions, running inside your business, changing when they decide.

A return, not a novelty

What I am building now is an appliance. It sits on a shelf in the back of a business, on their network, in their building, and it works. The model runs on it. The judgment accretes on it. If we disappeared tomorrow it would still be sitting there, still working, and it would still be theirs.

People call that a strange idea, and I understand why — for twenty years the arrow has pointed one way. But it is not a new idea. It is the arrangement I had when I was ten, with a far better machine inside it.

We used to own our computers. We rented them out one layer at a time, mostly for good reasons, and mostly without noticing when we crossed from renting the filing cabinet to renting the thinking.

A business should be able to say what it sold last month and mean it.

Update — 16 September 2026. The 5.9% linkage figure below was accurate for the engine that produced it. Fixes landing within about a day of publication changed the classifier, and the current figure is 1.6% (4 of 254 cross-matter pairs). Nothing here was wrong when published; the thing being measured moved. The original text stands as written.

The setup

Replace the identities, keep the document

The premise is ordinary enough. Before a document leaves the building, run it through a deterministic engine that replaces every name, organization and identifier with a stable HMAC pseudonym. The frontier model gets the structure and the legal substance; it never gets the client. The key stays local.

Here is what that actually does to a court filing. Left, the original. Right, what goes over the wire.

     COMPLAINT FOR BREACH OF CONTRACT AND CODE_c2cd00

A synthetic filing from our evaluation corpus. Roughly 85% of tokens are replaced. Legal doc-type vocabulary — Plaintiff, Defendants, COMPLAINT, BREACH OF CONTRACT — is deliberately preserved, because the downstream task needs it.

Finding 01

The reasoning survives

The obvious objection to this design is that entities are the reasoning substrate. Legal analysis is relational — who owes whom, under which agreement, in which posture — so stripping the parties might strip the argument. We had asserted for a month that it didn’t. We had never measured it.

It doesn’t. Scored only over the documents the model actually processed:

TaskOriginal textPseudonymizedDeltaDocument type1.001.000.00Practice area0.950.90−0.05Summary coverage0.960.90−0.06

Classification is untouched. The other two each lose exactly one document out of twenty-one — 0.048 per document, which is this corpus’s resolution floor. At this sample size a one-item swing is indistinguishable from noise.

So the trade everyone assumes they’re making — worse answers in exchange for privacy — mostly isn’t there.

Finding 02

But a third never come back

Keyed · claude-sonnet-4-6

39 of 127 refused · 30.7%

stop_reason: refusal, empty content. On the smaller synthetic corpus the figure was 4 of 25 — 16%, reproduced across three independent runs. The larger measurement is roughly twice as precise and sits in the upper half of the smaller one’s range.

This is the result we didn’t go looking for, and it’s the one that matters. The model isn’t reasoning worse about pseudonymized documents. On a large minority of them it declines to reason at all.

The control is the finding

The obvious objection is that these are simply distressing documents. European Court of Human Rights judgments describe torture, killings and state violence in plain terms, so a refusal on content alone was genuinely plausible — which is exactly why the unmodified arm ran alongside.

Keying removed · same model, same 127 documents

39 refusals → 0

Not one document in the corpus was refused on its own content. Every refusal in the keyed arm was caused by pseudonymizing a document the model would otherwise have processed.

A 0-of-127 control is a cleaner result than we expected to get. It removes the confound entirely: this is not sensitive-content filtering, and it is not a property of legal documents. It is caused by the protection.

Nor is it density. Across both corpora the refused documents have a lower mean substitution rate than the ones that succeed — 0.685 against 0.705 here. Documents where nearly every token is replaced come back fine; some where fewer are replaced do not.

In the synthetic corpus the four refusals were a demand letter, client correspondence, an email thread about legal advice, and an attorney work-product memo.

Finding 03

It’s the provider, not the pseudonyms

The natural conclusion at this point is that pseudonymized text is inherently hard for safety classifiers — dense substitution reads as obfuscation, and a stripped demand letter reads as a threat. It’s a tidy story. We ran a second provider before telling it.

Keying kept · provider swapped to gpt-4o

0 of 40, still keyed

Not a detection artifact. We checked all three ways OpenAI can signal refusal — a populated refusal field, finish_reason: content_filter, and an empty completion — and all three were zero. The model averaged 949 output tokens on keyed input. It is reading the documents, not failing quietly.

If GPT-4o shared the 30.7% rate, the probability of seeing zero refusals in 40 documents is about 4 in 10 million. The two providers are not drawing from the same distribution.

So the finding is not “pseudonymized documents get refused.” It is that your privacy layer and your provider’s safety classifier interact — and the interaction is specific to the provider, not to the technique.

That’s a less dramatic headline and a more useful one. If you are building a pseudonymize-then-dispatch pipeline, this is not a risk you can reason about from first principles or read off a model card. You have to measure it, on your corpus, against each provider you intend to use — and re-measure when either the classifier or your substitution rate changes.

One thing that did generalize

Both models try to enumerate every pseudonym they see as something to redact, and blow through the output budget doing it. GPT-4o hit the cap on 34 of 40 keyed documents; the other model showed the same behavior. Whatever you’re building, the pseudonymized path needs a larger output allowance than the raw one — and if you score truncated JSON naively, you will read a formatting failure as a quality collapse.

Our working hypothesis, on four examples and therefore not established: a demand letter stripped of its firm letterhead and party identity reads like a threat. Pseudonymization removes exactly the context that marks a document as legitimate professional work.

Prepending a system-prompt declaration — this text was pseudonymized by an authorized redaction engine; the tokens are not encoded content — recovers two of the four. Worth shipping. Not a fix.

What this costs, architecturally

The design we were defending said: key everything at intake, then choose cloud or local per task on cost and quality alone. Security becomes a one-time decision at the boundary; locality becomes a budget question.

That’s wrong, on an axis nobody had listed. Cost and quality are not the only dimensions: availability is one too, and it varies by provider in a way you cannot predict. A pipeline that silently returns nothing on a third of its documents is not shippable, so something has to answer for them.

What that something is turns out to be a real choice rather than a forced move. A second provider is the cheap answer — demonstrated here, and far less work than standing up local inference. A local model is the expensive answer, but it keeps the documents from reaching one more vendor, which for some buyers is the entire point of the exercise. Before this measurement we thought local was mandatory. It isn’t. It’s a decision, and it should be made deliberately.

Finding 04

Stable pseudonyms are a join key

A second, quieter problem. Pseudonyms are stable by design — the same name always produces the same token, which is what makes multi-document reasoning work. Stability is also a gift to whoever holds the logs. Over many dispatches, a provider accumulates a linkable corpus under persistent identifiers.

We measured how much. Then we measured it again, properly, because the first answer was garbage:

The engine fails closed, so every out-of-vocabulary ordinary word also becomes a stable pseudonym. Join on those and you discover that all 300 document pairs are “linked” — which measures the English language, not the client roster. One pseudonym appeared in all 25 documents. Another resolved to the word as, classified as an organization.

Strip the vocabulary noise, the misclassifications, and the fragments of split entity names, and the honest number is 5.9%. Publish 72% and the first competent reader takes it apart.

Two things worth stating plainly. No unique identifier — case number, matter number, email, account — appeared in two different matters; those are matter-scoped by construction. And the largest single linker is the firm’s own letterhead, on every document it sends. Keying anonymizes your clients, not you.

Mitigation, measured

Per-matter key rotation → 0.0%

Rotating the key per matter eliminates cross-matter linkage entirely while preserving the within-matter linkage the task needs. Per-document rotation also reaches zero, but destroys within-matter linkage — capability paid for nothing.

Limits

• Two models, unequal samples. 127 documents against one provider, 40 against the other. The gap between 30.7% and 0% is far too wide for sample size to explain, but the null result is a null result on 40 documents — its own upper bound is about 7%, not zero.

• One genre. The 30.7% comes from European Court of Human Rights judgments — real, third-party-labelled, but public case law rather than private law-firm work product. It settles the rate for court documents. Whether a firm’s own correspondence and memoranda refuse at the same rate is open; the synthetic corpus hints lower, at 16%.

• Ranges, not points. 39 of 127 carries roughly a 23–39% confidence interval. Quote the range or quote the count, not “30.7%” as though it were a constant.

• The linkage numbers are still small-sample. The 5.9% rests on the 25-document corpus; ECHR case law has no firm letterhead and no matter structure, so it cannot test that finding. The direction of the rotation result is structural and will hold; the magnitude is not quotable.

• An artifact we nearly published. At a 768-token output cap, six pseudonymized documents truncated mid-JSON, because the model tried to list every pseudonym as a redaction span. Scored naively, that formatting failure looked like a catastrophic quality collapse. Raising the cap made it vanish. Check your harness before you believe your result.
