Elon Musk predicts that in 4-5 years, running large-scale AI systems in space will be more cost-effective due to free solar power and easier cooling compared to Earth. However, Nvidia's CEO Jensen Huang believes that the challenges of massive AI data centers in space make it more of a dream for now. Musk highlights the escalating power and cooling requirements for AI clusters on Earth, stating that achieving terawatt-class AI demand is unattainable on Earth's grids. Challenges such as temperature swings and radiation make it difficult to establish AI data centers in space, with Huang referring to the idea as a dream due to various obstacles that need to be overcome.
