SpaceX founder Elon Musk stated that in a future interplanetary civilization, wealth and economic value will not be measured in traditional dollars, but according to the laws of physics. In his view, the development of robotics and space technology could completely transform the familiar financial system, rendering paper and digital money obsolete. The billionaire shared these insights on the podcast The Builders hosted by his biographer Walter Isaacson.

Transition to Physical Metrics

According to Musk, the future monetary equivalent could be based on fundamental physical quantities, among which he highlighted power, mass, and energy. The billionaire noted that currency will be measured in metrics such as watts and tonnage. Such a radical transformation could completely overturn the foundations of the global economy, where the US dollar currently acts as the primary global measure of goods, wages, and assets value.

Criticism and Economic Challenges

At the same time, industry experts note that the practical implementation of such a system will require a complex mechanism for comparing resources. Specialists emphasize that while watts reflect power and mass shows the amount of matter, neither of these physical parameters directly accounts for the actual scarcity or usefulness of a specific product.

Artificial Intelligence and National Debt

During the same podcast, the entrepreneur touched upon macroeconomics, stating that the large-scale deployment of artificial intelligence and robotics is the only realistic path to solving the US national debt problem. He reached this conclusion after serving as a special government employee in Donald Trump's administration in 2025. Furthermore, Musk predicts a gradual decrease in his own net worth due to tax extractions, although the Bloomberg Billionaires Index currently estimates his fortune at approximately $921 billion based on stakes in Tesla and SpaceX.

Significance of Space Transformation

Musk's reflections on the physical basis of future currency reflect a global shift in understanding the economics of the space era. Amid plans to turn humanity into an interplanetary species and develop long-term philanthropic initiatives, traditional financial instruments begin to appear limited. Moving toward energy and mass metrics may become an inevitable stage in the development of a technologically advanced society, where survival and expansion depend on pure physics rather than the issuance of banknotes.
