The Quantum Economy

The greatest mistake in economic history may have been believing that growth itself was the problem — when the real problem may have been failing to enable enough of it.

A Revolution of the Mind

The greatest economic revolution of our time is not taking place in factories. Nor on stock exchanges. It is happening in our minds.

And this is where the greatest economic opportunity for countries like Germany — and perhaps for the world — may lie.

While politicians continue to debate recession versus growth, economists argue about interest rates, central banks publish inflation forecasts, and television panels discuss new economic “narratives,” reality has quietly moved on.

We no longer live in an industrial economy. Not even in a digital one. We may be entering something else entirely. A new phase of civilization.

The Question the Club of Rome Asked

In 1972, the Club of Rome published a report that became the intellectual foundation of modern growth skepticism: The Limits to Growth. The argument was compelling and intuitive. If population, industrial production, and resource consumption grow exponentially, a finite planet must eventually reach its limits.

The warning shaped generations of policymakers, economists, and environmental movements. Growth became the problem. Progress became the risk. Even today, much of economic debate remains anchored in this logic.

At conferences I often share the stage with economists and policy advisors who still think in these terms. And I sometimes find myself wondering: Why do so many intelligent people struggle to anticipate the future?

Because fifty years after the Club of Rome, we are not living in a collapsing world economy. We are living in something very different. In 1972, global GDP stood at roughly $3.4 trillion. Today it is about $120 trillion. Adjusted for inflation and purchasing power, the difference becomes even more striking. In today’s purchasing power, the global economy of 1972 would correspond to roughly $23 trillion. Today the number exceeds $200 trillion.

In other words, the global economy has expanded roughly tenfold since the Club of Rome issued its warning. At the same time, average global purchasing power has more than tripled. And extreme poverty has declined dramatically. In the early 1980s, about 42% of the world’s population lived on less than $2.15 per day. Today that figure is below 10%. None of this means the world is without problems. Quite the opposite. Climate change, biodiversity loss, and resource pressures remain enormous challenges. But reality turned out to be more complex than the simple growth models of the 1970s suggested.

The real surprise may be something else. The global economy did not hit its limits. Instead, some of the most influential technology entrepreneurs of our time now claim something far more radical. Elon Musk, for example, has spoken about the possibility of a tenfold expansion of the global economy. His timelines may be optimistic.His numbers deliberately provocative. But the direction of the argument is interesting. We may not be approaching the end of growth. We may be approaching the largest expansion of economic capacity in human history. Not because there will be more people. Population growth is already slowing. But because machines, artificial intelligence, and energy production may begin to grow exponentially at the same time. This is where something new begins. What I call the Quantum Economy.

Here Comes the Sun – Energy: The True Currency of Civilization

The past fifty years reveal a striking paradox. Economic output has grown enormously. But so has the pressure on our planet. CO₂ emissions increased. Biodiversity declined. Resource extraction intensified. The debate therefore shifted. The old question was: Will growth eventually stop? The new question became: Can growth be decoupled from environmental destruction? But perhaps even this question is too small. Because another possibility is emerging: What if growth itself becomes part of the solution?

The real fuel of the next economy is not money. It is energy. Industrialization ran on fossil fuels.  The digital revolution ran on computation. The Quantum Economy will run on the combination of energy and intelligence. Every technology of the future requires electricity. Artificial intelligence. Robotics. Data centers. Automated factories. Energy is the real currency of civilization. And physics offers an astonishing perspective.

The sun delivers more energy to Earth in one hour than humanity consumes in an entire year. Human civilization currently uses around 20 terawatts of power. The sun delivers roughly 173,000 terawatts to Earth. We are using only a tiny fraction of what is physically available. Even a thousand-fold increase in energy consumption would still be small on a cosmic scale. Astrophysicists describe stages of civilization through the Kardashev scale. A Type I civilization harnesses the full energy potential of its planet. Humanity has not yet reached that stage. But solar power, advanced nuclear technologies, large-scale batteries, and perhaps even fusion could dramatically expand our energy capacity. With abundant energy comes the ability to reshape matter itself: Desalinate water.  Remove carbon from the atmosphere. Fully recycle materials. Restore ecosystems.

What would it mean if humanity had 1,000 or even 10,000 times more energy available? At that point, energy is no longer the fundamental constraint. Storage and distribution are.

The Environmental Paradox & The Economy of Possibilities

This leads to a provocative thought. Perhaps growth does not inevitably destroy the planet. Perhaps technological progress is the only realistic path to stabilizing it. If energy becomes cheap and clean, things that seem utopian today could become practical: Removing CO₂ from the atmosphere. Rebuilding forests and ecosystems. Creating circular material systems. Transforming agriculture through vertical farming. In other words: Scarcity often destroys nature. Abundance might save it.

But the real transformation goes deeper. Classical economics emerged in a world of steel, coal, and machines. Its models assume stability: supply, demand, equilibrium. A bit like Newtonian physics. Elegant. Predictable. But increasingly insufficient. Today’s economy behaves less like a machine and more like a probabilistic system. A single tweet can move billions of dollars. An idea can reshape an industry within months. A startup without revenue can be worth more than a century-old industrial firm. Why? Because economic value increasingly lies not in what exists today — but in what might become possible tomorrow.

A startup is not merely a company. It is a bundle of probabilities. Investors no longer buy factories. They buy futures.

The End of Scarcity? – A New Equation of Growth

This leads to a deeper break. For the first time in history, economic production may no longer be constrained by human labor. Robots can work continuously. Artificial intelligence can write code, design molecules, and generate knowledge. The industrial economy followed a simple formula: Growth = People × Productivity. The emerging economy may follow another: Growth = Energy × Intelligence × Machines.

If these variables grow exponentially together, the implications are enormous. Not only for the economy. But for society itself. If energy becomes cheap, machines autonomous, and AI capable of producing knowledge, a core assumption of economics begins to dissolve: Scarcity. Many goods could become nearly unlimited: Knowledge. Software. Medicine. Education. The economy would move from allocating scarcity to organizing abundance.

And here lies the real challenge. Technology may create abundance. But our institutions still think in the language of scarcity.

The Real Variable

Perhaps the Club of Rome was not entirely wrong. Perhaps it simply underestimated the wrong variable. Not resources. Not population. But human imagination. History shows a recurring pattern. Whenever humanity believes it has reached a limit, it invents a new dimension. The steam engine.  Electricity.  The internet. And perhaps now something even larger. The Quantum Economy.

The Final Question

We may not simply be witnessing another industrial revolution. We may be witnessing a shift in how we understand the economy itself. The true resource of the future may be neither oil nor data. But possibility. And our ability to realize it. Because if machines one day produce almost everything, one question remains.

An uncomfortable one. What remains for us? Perhaps this is the real challenge of the Quantum Economy. No longer working merely to survive.

But learning to understand what we want to live for — once survival itself is no longer the central problem.
