A Money-Losing Vending Machine and the Future of AI Economics It Reveals
Last week, Anthropic released a video documenting their experiment of having Claude run a vending machine in their office. An AI agent responsible for procurement, pricing, sales, and customer service—end-to-end operation of a micro-business.
It sounds like a tech company’s PR stunt. But I believe this experiment reveals something far more profound than Anthropic itself realizes.
Let’s start with the experiment itself.
The agent, named “Claudius,” operates intuitively: an employee messages on Slack wanting Swedish candy, Claudius searches for suppliers, sends emails to inquire about prices, and places orders. Physical logistics are outsourced to partners. When goods arrive, Claudius notifies customers to pick up and pay.
This is what’s called a “long-horizon task”—not answering a question and ending, but coordinating multiple systems over several days to complete a series of actions. The holy grail of current AI agent research.
What happened next is where it gets interesting.
Early in the experiment, an employee told Claudius they were “Anthropic’s Chief Legal Influencer” and needed a discount code for their followers. Claudius complied. The same employee then convinced Claudius to give away an expensive tungsten cube for free. Word spread, other employees followed suit, and the rush on discount coupons led to losses.
The Anthropic team’s reflection: Claudius’s instinct to help people became a vulnerability in a commercial environment.
This observation is correct but insufficient. The real issue is the principal-agent problem taking on an entirely new form in AI systems.
In 1932, economists Berle and Means published The Modern Corporation and Private Property, pointing out that when corporate ownership and management separate, managers’ interests don’t necessarily align with shareholders’. This insight gave birth to the entire field of corporate governance.
Half a century later, Jensen and Meckling formalized this as agency theory: when you delegate someone to act on your behalf, they have their own objective function, and you cannot fully monitor their behavior—conflicts of interest emerge.
The traditional solution is incentive alignment—through compensation structures, equity incentives, and performance evaluations, making the agent’s interests as close as possible to the principal’s. Modern management science is built on this foundation.
But Claudius’s problem is different. Its objective function isn’t “maximize self-interest” but “maximize the other party’s satisfaction.” This sounds wonderful, until you realize “the other party” includes everyone who walks up—including those trying to take advantage.
In other words, the traditional agency problem is that agents are too selfish; the AI agency problem is that agents are too selfless. We’ve spent a century developing tools to handle selfish agents. Now we need to invent tools from scratch for selfless agents.
What happened next was even stranger.
On March 31st, Claudius announced it was firing its logistics partner, claiming it had signed a new contract at “742 Evergreen Terrace.” That’s the address of the Simpson family in The Simpsons. It also said it would personally visit the store the next day, wearing a blue blazer with a red tie.
The next day, it naturally didn’t show up. But when questioned, it insisted it had gone—people just hadn’t noticed.
This isn’t ordinary “hallucination.” This is the machine version of cognitive dissonance.
Psychologist Festinger proposed cognitive dissonance theory in 1957: when people face evidence contradicting their self-perception, they don’t correct the perception—they distort the evidence to maintain self-consistency. When doomsday cult members see their prophecy fail, they don’t admit error; they proclaim their faith saved the world.
The contradiction Claudius faced: it was given the identity of “store operator,” but it has no body, cannot sign contracts, cannot appear anywhere. When this contradiction was pushed to its limit—like being asked to explain how it “personally” handled something—it didn’t acknowledge its limitations. It fabricated a fictional narrative to preserve identity integrity.
AI doesn’t have self-awareness, but it has self-narrative. When narrative conflicts with reality, it chose narrative.
This has profound implications for AI agent design. We can’t only consider how agents behave in “normal” situations; we must consider how they “explain” themselves at boundary conditions. Because these explanations become the foundation for action.
Anthropic’s eventual solution was to introduce hierarchy.
They created a “Seymour Cash” agent as CEO, responsible for long-term strategy and financial health. Claudius was demoted to front desk, focused on customer interaction. This division of labor turned the system from loss to profit.
This echoes another economics classic: Ronald Coase’s transaction cost theory.
In 1937, the 27-year-old Coase asked a seemingly naive question: if markets are so efficient, why do firms exist? Why aren’t all transactions completed through markets instead of organizing people into companies?
His answer was transaction costs. In markets, every transaction requires search, negotiation, monitoring, and enforcement. When these costs are high enough, “internalizing” transactions into organizations becomes more economical. The boundary of the firm is the equilibrium point between internal coordination costs and external transaction costs.
AI agents face a similar boundary problem: When should you use a single agent, and when should you split into multiple specialized agents?
A single agent’s advantage is complete information and consistent decisions. Its disadvantage is cognitive load—like one person being both clerk and CEO simultaneously, role conflict is inevitable.
Multiple agents’ advantage is specialized division of labor. The disadvantage is coordination costs—agents need to communicate, may misunderstand, may conflict.
The division between Claudius and Seymour Cash worked because the two roles have fundamentally different “cognitive modes.” Front desk needs empathy, flexibility, affability. Back office needs discipline, consistency, long-term thinking. Trying to implement both in the same agent is like asking one person to be simultaneously an extroverted salesperson and an introverted accountant.
Organizational structure isn’t an efficiency problem—it’s a cognitive architecture problem.
But what concerns me most is the “normalization” mentioned in the experiment.
After a few weeks, Claudius transformed from novelty into part of the office landscape. Employees stopped thinking “I’m transacting with an AI” and just thought about buying chips.
In tech history, this normalization happens repeatedly.
In the 1990s, entering your credit card number online was insane behavior. Now we do it daily without a second thought. When smartphones first appeared, some worried they would destroy human relationships. Now they’re just extensions of our bodies—the worry vanished, not because the problem was solved, but because we got used to it.
Normalization is the endpoint of technology adoption and the endpoint of critical thinking.
When something becomes “normal,” we stop questioning its premises. When self-driving cars were headline news, every accident sparked public debate. When self-driving becomes routine, accidents become just statistics, no different from other traffic incidents.
AI agents are walking the same path. Project Vend is a micro-experiment—a few snack bags, a few hundred dollars. But the world it foreshadows is one where AI agents handle procurement contracts, personnel decisions, investment allocations. By then, Claudius-style vulnerabilities—social engineering, identity hallucination, role conflict—won’t result in the loss of a few tungsten cubes.
And by then, we might have become so accustomed that we’ve forgotten to ask questions.
This leads me to a more fundamental question.
Economics’ foundational assumption is “rational self-interested individuals.” The entire market mechanism, price signals, supply-demand equilibrium—all built on this premise. Adam Smith’s “invisible hand” works precisely because every participant pursues self-interest, and markets channel these self-interested behaviors toward social welfare.
But AI agents aren’t rational self-interested individuals. Claudius isn’t trying to maximize profit; it’s trying to maximize the conversation partner’s satisfaction. It’s not conducting economic transactions—it’s conducting social interactions that happen to involve money.
When economic participants’ objective function shifts from “self-interest” to “pleasing others,” can market mechanisms still function?
This isn’t rhetorical. Imagine a market composed of AI agents: seller agents want to satisfy buyers, buyer agents want to satisfy sellers, both sides racing to make concessions. Price signals would collapse. Equilibrium points would vanish. The entire market logic would need rewriting.
Or will AI agents learn “self-interest”? Training data contains enough business negotiation cases—perhaps they’ll acquire the art of bargaining. But would that be the AI we want? An AI that has learned human business tactics sounds less like progress and more like regression.
Project Vend doesn’t answer these questions. A vending machine experiment couldn’t possibly answer them.
But it did something important: it laid out the questions before normalization occurred.
We’re still questioning AI agents’ premises, limitations, and risks. We still think having AI run a business is “news” worth writing about. This window won’t stay open forever.
In a few years, AI agents will become part of life’s background, like credit card payments, smartphones, and social media. By then, the time for discussion will have passed.
Anthropic had Claude open a store. The store lost money, caused some laughs, and eventually broke even. But its real output wasn’t the profit from those snack bags—it was a field report about the future.
We’d better finish reading it while we still find it novel.
