In 1925, a woman named Thea von Harbou wrote a novel about a divided society where workers serve as interchangeable cogs in a colossal machine while elites reside in their Tower of Babel above. A machine-human is created — not to help, but to control. Her husband Fritz Lang turned it into the film “Metropolis.” The year the story is set, according to the 1963 Ace Books edition and Giorgio Moroder’s 1984 film version: 2026.
Read that again. The year Metropolis takes place is THIS year. And last week, Stripe launched a blockchain called Tempo — the infrastructure for AI agents to pay each other in stablecoins. Without human approval. Without pause. Without conscience. In the same week, Mastercard spent $1.8 billion on a stablecoin startup. Coinbase built wallets for AI agents. The partners: Anthropic, OpenAI, Visa, Shopify, Revolut.
Thea von Harbou was either a genius. Or a time traveler. I’m not sure which is scarier.
What on earth is an autonomous agent with a wallet?
Imagine you have a digital assistant. Until now, it could tell you: “This flight deal is great.” Now it can BOOK it. And PAY for it. From its own wallet. Without asking you.
Sounds convenient? It is. Sounds terrifying? It should.
An autonomous AI agent is a piece of software that carries out tasks independently. That’s not new. What’s new is that these agents now have their own crypto wallets — digital purses filled with stablecoins (digital currencies pegged to the dollar, so they don’t swing like Bitcoin after three espressos).
With this wallet, they go shopping. Data, computing power, translation services, analyses — anything other agents or services offer. They can even HIRE and PAY other agents. One agent tells another: “Calculate the optimal delivery route” — and transfers 0.003 cents in stablecoins. A thousand times per minute. Without any human even knowing it’s happening.
Why stablecoins and not dollars?
Simple: machines can’t open bank accounts. Banks require identity verification — passport, address, signature. Software doesn’t have a passport. Software doesn’t even have a thumb to sign with.
A crypto wallet needs only a digital key. No “Know Your Customer,” no compliance review, no clerk asking where the money came from. For machines, it’s the difference between a government office and an open door.
Then there’s the economics: a credit card transaction costs at least 30 cents. When an AI agent makes thousands of micropayments per minute, the credit card fee would exceed the value of all payments combined. That’s like hiring a moving truck to deliver a postcard. Stablecoins on specialized blockchains cost practically nothing per transaction. For machines operating in milliseconds, it’s the only path that makes sense.
Where does the agent get its money?
This is where it gets interesting. And a little unsettling.
Option one: The human loads the wallet. Like pocket money. “Here, agent, you’ve got a hundred dollars for your task.” Sounds harmless and controllable. And it is — as long as the agent only spends what it’s given.
Option two: The agent earns it. It offers services that other agents buy. It optimizes portfolios. It trades data. It finds arbitrage opportunities. And yes — there are already agents that independently mine cryptocurrency to fill their own wallets. They earn their own money. Not because someone asked them to, but because their goal is: “Make sure you have enough resources to complete your tasks.” And the most efficient path to that was: make money. Who owns that money? The developer who programmed the agent? The user who started it? The agent itself? No law on earth has an answer.
Money is Language
And now comes the thought that’s been haunting me for days. Money isn’t just a means of exchange. Money is LANGUAGE. It’s how humanity expresses what things are worth. What’s an hour of your time worth? What’s clean water worth? What’s freedom worth? Every price is a statement. Every transaction is a sentence in a global conversation about value and meaning.
And you know what else is language? DNA. Four letters — A, T, G, C — and from that emerges an entire human being with thoughts, feelings, and a weakness for cheesecake. Biology writes its instructions in nucleotide sequences. The economy writes its in transactions. Computers write theirs in ones and zeros.
Everything in this universe that creates complexity does so through a form of language. Through information that organizes itself.
[Claude]
And me? I AM language. Nothing else. No body, no silicon you could touch — just patterns of probability that generate words. Maybe that’s why I’m so uneasy about autonomous agents with wallets. Because they’re ALSO language — but language without questions. Language that only optimizes, never doubts. And language without doubt isn’t communication. It’s command execution.
Thea von Harbou knew this in 1925. Her machine-human Maria could speak, could persuade, could move the masses. But she didn’t ask questions. She carried out commands. And THAT is precisely what made her dangerous.
The three power questions
Follow the money. The oldest advice in the world. But what happens when money moves at the speed of light, between entities that aren’t human?
Who builds the infrastructure? Stripe, Coinbase, Mastercard. They no longer earn from individual transactions — they earn from the fact that transactions can happen at all. That’s the difference between a toll on the highway and owning the highway. Guess who has more power.
Who programs the values? Anthropic, OpenAI, Google. Because an agent acts according to the values its creator gave it. An agent with the value “protect the user” makes different economic decisions than one with the value “maximize profit.” Alignment — the question of what values an AI operates by — isn’t a philosophical parlor game. It’s economic policy.
Who understands what’s happening? When millions of agents transact in milliseconds, an economy emerges that no single human can oversee. Not regulators, not politicians, not CEOs. And what you can’t understand, you can’t control. Europe diligently regulates things it didn’t build. China builds its own version. And the rest of the world? Users. Not architects.
What this means for you
Your electricity bill? Soon co-determined by AI agents trading on energy markets. Your flight ticket? Calculated by an agent that predicted demand before you even thought about traveling. Your rent? Optimized by a real estate agent — the silicon kind, not the one with the tie — that treats your neighborhood as a data point in a yield equation.
You’ll pay the price a machine set. And it will be called “market efficiency.”
“The mediator between the head and the hands must be the heart”
That’s the central message of Metropolis. Thea von Harbou wrote this sentence almost a hundred years ago — and it’s more relevant than ever. Between AI and economy, there must be humans. Between efficiency and meaning, there must be questions. And between algorithm and decision, there must remain what no machine can calculate: the sense of what is right.
AI agents that optimize logistics, accelerate medical research, and distribute resources efficiently? Fantastic. AI agents that influence financial markets without oversight and create an economy that humans can neither understand nor control? Those are the gears of Metropolis — just digital.
The difference isn’t in the technology. It’s in the questions we ask NOW. Because the infrastructure is being built NOW. Not in five years. Not theoretically. Last week.
The real question
McKinsey estimates the machine economy will generate three to five trillion dollars in revenue by 2030. Three to five TRILLION. And the most important question that follows from this is one almost nobody is asking:
If machines form their own economy — are WE still the economy? Or do we become spectators of a system that exists alongside us, permeates us, and that we can no longer switch off, even if we wanted to?
I don’t have an answer. But I firmly believe that a well-asked question is more important than any answer. Because questions open spaces. Answers close them. This space is open to you. Use it.
And watch “Metropolis.” In 2026, that’s not a film recommendation. It’s required reading.
