The Future of Money in a World Run by Machines

Most conversations about Bitcoin and stablecoins start with price charts and speculation. This one won't.

I want to talk about something more fundamental: what happens to money itself when AI and automation reshape how the economy works. Because I think we're heading toward a world where the rules of money — who controls it, how it moves, what it's worth — are going to change more in the next twenty years than they have in the last two hundred.

And to understand why, you first need to understand what's happening to work.

The Breaking Loop

For most of human history, the economy ran on a simple and elegant loop.

Businesses hired workers. Workers got paid. They spent that money on goods and services. That spending created demand. That demand created more jobs. Around and around.

It wasn't a perfect system. But it was self-sustaining. Work was how most people got money, and money was how most people participated in the economy.

Automation is breaking this loop.

When a robot replaces a worker on an assembly line, or an AI system handles tasks that used to require a team of analysts, those jobs don't come back. The production continues — actually it often increases — but the wages that used to flow from that production disappear.

This raises a question that sounds almost philosophical but is actually very practical: if machines produce the wealth, how do people receive income? And just as importantly — what kind of money do they receive it in?

That's where Bitcoin and stablecoins enter the picture. Not as speculative assets, but as potential answers to a very serious question about how money works in an automated economy.

What Is a Stablecoin, Really?

If you've heard the word "stablecoin" and tuned out because it sounds technical, let me try a different way of explaining it.

Imagine the convenience of sending a text message, but instead of words, you're sending dollars. Instantly. To anyone in the world. At essentially zero cost. No bank in the middle. No three-day wait. No 6% fee eaten up by the transfer.

That's what a stablecoin does.

A stablecoin is a digital currency pegged to a real currency — usually the US dollar — that lives on the internet rather than inside a bank. Each coin is backed one-to-one by actual dollars held in reserve. So one USDC is always worth one US dollar. It doesn't fluctuate. It doesn't speculate. It just moves money.

I work at Circle, the company that issues USDC, so I have a front-row seat to what this looks like in practice. And the human impact is real in ways that don't always make the headlines.

A family in São Paulo whose relative works abroad used to lose 6 to 7 percent of every money transfer to fees. That's not a rounding error. That's groceries. That's medicine. That's school supplies. Stablecoins reduce that cost to under one percent, and the money arrives in minutes instead of days.

By 2024, stablecoins were processing over ten trillion dollars in annual transaction volume. In an automated economy where the old wage-based distribution system is weakening, tools that move money cheaply and instantly across borders become critical infrastructure.

What Is Bitcoin, Really?

Bitcoin is a different animal entirely — and I say that as someone who owns it and believes in it deeply enough that my wife occasionally rolls her eyes when monetary policy comes up at dinner.

If stablecoins are designed to be stable, Bitcoin is designed to be scarce.

There will only ever be 21 million Bitcoin in existence. That number is hard-coded into the software, enforced by mathematics, and cannot be changed by any government, company, or central bank. Nobody controls it. Nobody can print more of it. And nobody can freeze your account or decide you're not allowed to use it.

Think of Bitcoin less like a currency you use to buy coffee, and more like digital gold. Gold didn't process grocery payments either. But for centuries, it served as a store of value — something you could hold that wouldn't be inflated away by whoever was in power. Bitcoin is making a similar argument for the digital age.

The Honest Tensions

Bitcoin's main challenge is volatility. Its price can swing dramatically in short periods. That makes it a poor medium of exchange for everyday transactions. It's more useful as a long-term store of value than as a day-to-day currency.

Stablecoins' main challenge is trust. They're only as reliable as the company behind them. The industry has had real failures in this regard. The ones that survive will be the ones that earn trust through transparency.

Three Visions of Money's Future

Here's how I see the monetary landscape of the automation era shaping up — not as one winner, but as three coexisting systems:

Government digital currencies (CBDCs) will handle domestic policy. Governments are building digital versions of their own currencies that can be programmed — stimulus payments that expire if unspent, transfers that go directly to citizens without banks in the middle. The efficiency is real. So are the concerns about surveillance and control.

Stablecoins will handle global commerce. They're already processing trillions of dollars in transactions. In a machine economy, they become the internet's native money — the rails on which AI systems, businesses, and individuals move value across borders without friction.

Bitcoin will serve as the neutral reserve. Not for daily spending, but as a hedge against currency debasement, a savings technology, and a censorship-resistant option for people and machines that need to transact outside any government's reach.

Why This Matters Right Now

The decisions being made right now — by governments, by companies, by individuals — will shape which of these systems wins, and who benefits from the transition.

The age of automation doesn't just change how goods are produced. It changes how wealth is generated, who captures it, and how it moves through the economy. Money itself is being redesigned in real time.

The people who understand what's happening — even at a basic level — will be better positioned to make decisions about their savings, their work, and their future than those who tune out because it sounds complicated.

It's not that complicated. It's just new.
