Elon Musk: Earth's physical limits could constrain AI growth

Elon Musk recently said that the future growth of artificial intelligence (AI) could eventually be limited by Earth's physical constraints. Speaking during a conversation with JPMorgan Chase CEO Jamie Dimon, the SpaceX CEO argued that the planet can support only a limited amount of AI computing power before energy and infrastructure become bottlenecks. According to Musk, the solution may lie beyond Earth. He pointed to the Moon as a potential location for future AI infrastructure, saying it could support far more computing capacity than is possible on Earth.

Elon Musk says Earth has limits for AI growth

During the discussion, Elon Musk said Earth can support only a fraction of the AI computing power that could be built elsewhere. "I think we can do probably somewhere around 1 terawatt per year of AI space compute from Earth, but we can do 1,000 terawatts or more from the Moon," Musk said. He argued that the Moon offers several advantages for building large-scale AI infrastructure, including lower gravity and the absence of an atmosphere. "Because the Moon has no atmosphere and about one-sixth Earth's gravity, you can use an electromagnetic accelerator," Musk said. "You don't need to use rockets to do AI data centers into deep space from the Moon. You can literally just shoot them like a railgun type of thing."

Moon first, Mars later

During the interaction, Elon Musk also outlined a broader vision that starts with the Moon and eventually extends to Mars. “We can build a self-growing city on the Moon faster than we could do so on Mars,” he said. He described the Moon as a place where infrastructure and manufacturing could be developed before expanding farther into space. Speaking about Mars, Elon Musk suggested that the planet could one day become more Earth-like. "If you warm up Mars, you could one day make Mars like Earth, meaning with liquid oceans and life and where you could walk outside without a spacesuit type of thing," he said. Elon Musk added: "I call Mars a fixer-upper of a planet, but it's got a lot of potential."
