Elon Musk Says Money Won't Matter by 2036. Here's Why He's Wrong

Elon Musk told The Economist that by 2036, AI and robots will produce so many goods and services that money itself becomes irrelevant. "What do you need money for in that case?" he asked.

The Tesla CEO argued that the ratio of money to goods and services determines inflation, and that a massive surge in output would let governments issue checks without causing prices to rise. "These things were relevant in the past–they will not be relevant in the future," he said.

The logic has a problem. Musk treats money as a simple counter, a token that tracks the volume of stuff in the economy. That view misses the demand side of the equation.

People hold cash not just to spend it but as a store of value. When the economy becomes more productive, the demand for money itself can rise. If it does, the purchasing power of each unit increases, and the simple ratio Musk cites gets pulled in two directions at once. An increase in the quantity of money pushes prices up. An increase in the demand to hold money pushes them down. Which force wins depends on relative magnitudes, not just the production line.

There is a deeper issue. Musk's vision implies that a more productive economy reduces the need for exchange. The opposite is true. When production becomes more complex and specialized, the number of potential trades explodes. Steel makers need software. Chip designers need lithography machines. No one can barter their way through a supply chain that spans 20 countries and 500 firms. Money makes that calculation possible.

The Austrian economist Ludwig von Mises called this the problem of economic calculation. Without a common medium of exchange, there is no way to compare the value of a truckload of rare-earth magnets against a month of cloud compute time. The more sophisticated the capital structure, the more essential money becomes, not less.

Musk's other claim – that governments can just mail checks to displaced workers – assumes that technological change creates a fixed pool of jobs that shrinks over time. History suggests otherwise. The mechanization of agriculture eliminated millions of farm jobs in the 20th century and created millions of others in machinery, logistics and food processing. The same pattern repeated with the internet, which killed retail jobs and created roles in e-commerce, digital marketing and cloud infrastructure.

Workers using better machines can produce more per hour, which tends to raise wages over time. The conflict between capital owners and labor is not the zero-sum game Musk's stimulus-check solution implies. The real question is not whether money will exist but whether the transition to a more automated economy distributes its gains broadly enough to avoid political backlash.

That is the question Zanny Minton Beddoes, The Economist's editor-in-chief, pressed on. She asked Musk about higher taxes on the rich and, more pointedly, "Otherwise, what do people live off?" Musk did not answer that question. He said the treasury should simply issue checks. Beddoes raised the inflation objection. Musk replied that inflation is "simply the ratio of money to goods and services" and that a 1,000% increase in output would make deflation the risk, not inflation.

A 1,000% increase in output within a decade is not a forecast. It is a thought experiment. If it happened, the demand for money would shift in ways no one can model. The U.S. money supply more than doubled between 2020 and 2022. Inflation spiked even as supply chains strained to keep up. The ratio Musk cites did not hold in that real-world test because velocity and demand for cash balances moved unpredictably.

Money matters precisely because it is not just a unit of account. It is a store of value, a medium of exchange and the basis for economic calculation. The more productive the economy, the more complex those functions become. Musk's 2036 vision eliminates the problem by eliminating the mechanism. That is not a forecast. It is a category error.

The interview ended without resolving the contradiction. If money does not matter, why send checks? If it does matter, the ratio argument is incomplete. Musk's answer – that checks are a transition policy – punts the question. The transition is the hard part. And the hard part is about distribution, not production.
