In Brief Answers to the Big Questions, Stephen Hawking explains how Albert Einstein transformed our understanding of the universe.

Before Einstein, matter and energy were regarded as separate things. Einstein’s famous equation, E = mc², revealed something astonishing: mass and energy are fundamentally related. Matter can be understood as a concentrated form of energy.

This insight allowed physicists to simplify their view of reality. What appeared to be multiple ingredients could, at a deeper level, be understood as different expressions of the same thing.

I often wonder whether economics is approaching a similar moment.

For centuries, economists have argued that production depends upon two fundamental ingredients: labour and capital.

Labour is human effort, skill, knowledge, creativity, and time. Capital consists of tools, machines, factories, infrastructure, technology, and financial resources used to produce goods and services.

But where does capital come from?

Every machine was designed by a human mind. Every factory was built by human hands. Every technology emerged from human knowledge accumulated over generations. Even money derives its value from human trust and social cooperation.

This raises an intriguing question.

If capital is itself the accumulated result of past labour, knowledge, and organization, then is labour the more fundamental ingredient of economic life?

Historically, this question has shaped political and economic thought.

One tradition emphasizes the importance of private ownership of capital and the incentives it creates. Another emphasizes the central role of labour and argues that workers should have greater control over the wealth they help produce. Much of modern political history can be understood as a debate over the relationship between these two forces.

Yet artificial intelligence may transform the debate entirely.

For most of human history, capital depended upon labour. Machines could amplify human productivity, but they could not replace human intelligence. Even the most advanced technologies required people to operate, supervise, and improve them.

AI challenges this assumption.

For the first time, humanity is creating systems capable of performing not only physical tasks but also cognitive ones. Machines are beginning to write, analyze, design, negotiate, diagnose, and create. Capital is acquiring capabilities that were once unique to human beings.

This development presents two very different futures.

In the first future, AI becomes concentrated in the hands of a small number of corporations, governments, and wealthy individuals. As intelligent machines perform more economic tasks, the demand for human labour declines. Wealth accumulates around ownership rather than participation. Millions may find themselves excluded from meaningful economic activity.

The result would not simply be unemployment. It could lead to deeper social consequences: declining social mobility, reduced family formation, growing inequality, political instability, and a loss of purpose for many people.

In the second future, AI dramatically increases productivity while its benefits are broadly shared. Technology lowers the cost of essential goods and services. People work fewer hours while enjoying higher living standards. Education, healthcare, and knowledge become more accessible. Human beings gain greater freedom to pursue creativity, learning, family, and community.

The technology itself does not determine which future emerges.

The crucial question is ownership.

Who owns the productive intelligence of the future?

Who benefits from the wealth generated by increasingly autonomous systems?

Who decides how these technologies are deployed?

These questions may become more important than traditional debates between capitalism and socialism. The challenge of the twenty-first century is not merely how to create more wealth. It is how to ensure that technological progress remains aligned with human flourishing.

An economy should not exist merely to maximize output. Nor should technology be treated as an end in itself.

The ultimate purpose of economic activity is to improve human life.

If AI becomes the most powerful productive force in history, then humanity must ensure that it serves people rather than rendering them economically irrelevant.

The defining question of our age may therefore be remarkably simple:

As machines become more capable, will technology concentrate prosperity, or will it democratize it?

The answer may determine not only the future of economics, but the future of human civilization itself.
