Elon Musk sees space as AI’s ultimate frontier. Uninterrupted solar power. No earthly grid constraints. Data centers orbiting Earth, powering the next wave of artificial intelligence. But SpaceX’s own words in a confidential filing paint a stark picture: those dreams rest on unproven tech that might never pay off. The company laid it bare ahead of a blockbuster IPO targeting $1.75 trillion valuation. “Our initiatives to develop orbital AI compute and in-orbit, lunar, and interplanetary industrialization are in early stages, involve significant technical complexity and unproven technologies, and may not achieve commercial viability,” the S-1 excerpt states, as reported by Reuters . Musk pushed the idea hard at Davos. Unconstrained sunlight beyond Earth’s atmosphere makes orbit the “lowest-cost place to put AI,” he said. True in two or three years, tops. SpaceX plans up to one million satellites—each larger than the International Space Station—to form massive orbital compute clusters.…
