Elon Musk has shared a bold vision for the future of space exploration, suggesting that the industry's growth could be far quicker than many expect. In a recent discussion, David Holz, founder of the AI image generation company Midjourney, proposed a scenario where if the space industry began modestly in 2030 and its production doubled every year, humanity could reach the "type I" level on the Kardashev scale by 2064 and the "type II" level by 2098. The Kardashev scale is a way to measure a civilization's technological advancement based on the amount of energy it can harness. Even if the growth rate were slower—doubling every two years—these milestones would still be reached by 2096 and 2165, respectively. Musk, however, thinks this timeline is too conservative, predicting that production on the Moon and Mars could accelerate much more rapidly, limited only by natural constraints. Musk has spoken about the idea of a "self-growing" lunar city, where robots would build factories on the Moon using local materials, reducing the need to transport everything from Earth. During SpaceX's first results presentation on August 4, he also described an electromagnetic catapult that could launch payloads into space without traditional rockets. While admitting this idea sounds "completely crazy," he believes it could be a game-changer for space travel. Musk also believes that the energy demands of artificial intelligence will eventually surpass what Earth can supply. He suggests that a lunar base could use solar power to run AI systems, marking an early step toward achieving type II status on the Kardashev scale. However, a study published in Frontiers in Space Technologies in September highlights a major challenge: a city of one million people on the Moon would consume known lunar water reserves in just 2.4 years. With thorough recycling similar to that used on the International Space Station, the water supply would last about a century, but this still presents significant logistical hurdles. Despite these ambitious plans, much remains uncertain. SpaceX's Starship, the massive rocket intended to transport equipment and people to the Moon and Mars, is still undergoing testing. Musk's vision aligns closely with the goals he has set for SpaceX investors: his compensation will only be fully realized if the company achieves a market value of 750 billion dollars and establishes a permanent Martian colony with at least one million residents. For now, the transition from vision to reality remains a work in progress.
