Elon Musk said building factories on the Moon and Mars is necessary to establish a future economy beyond the use of dollars [1].

This vision represents a fundamental shift in industrialization, moving manufacturing from Earth to other celestial bodies to expand the scale of human wealth. Musk said such an infrastructure is a prerequisite for the creation of a multi-planetary economy.

Speaking Sunday, Musk said it is "not impossible" to become the first quadrillionaire in human history [3]. However, he noted that this level of wealth — reaching 1 quadrillion dollars [3] — cannot happen within the current economic framework of Earth. He said that the development of lunar and Martian industrial sites must come first to enable this growth.

Regarding the timeline for these projects, Musk said, "We will have factories on the Moon within 20 years" [2]. These facilities would serve as the foundation for a broader economic system that operates independently of traditional terrestrial currencies.

While the technical challenges of lunar manufacturing are significant, Musk said the move is a logical progression for humanity. The proposal involves not only the Moon but also Mars, creating a network of production hubs across the solar system [1]. This expansion would allow for the extraction and processing of materials in space, reducing the reliance on Earth-based resources.

Musk has consistently linked his goals for SpaceX and Tesla to the broader objective of making humanity multi-planetary. By establishing a manufacturing presence on the Moon, he said that the global economy could transition into a cosmic economy [3].

Musk's focus on lunar factories highlights a transition from exploration to exploitation of space resources. By proposing a 'quadrillionaire' economy, he is signaling that the next phase of capitalism may rely on the discovery and industrialization of extraterrestrial materials, which would fundamentally alter global markets and the definition of wealth.
