Musk said 80% of Terafab’s compute output would be directed toward space-based orbital AI satellites, with only 20% for ground-based applications. He argued that solar irradiance in space is roughly 5x greater than at Earth’s surface, and that heat rejection in vacuum makes thermal scaling viable. His conclusion: orbital AI compute could become cheaper than terrestrial alternatives within 2-3 years... I am not really into this betting market thing, but I will put my life savings that orbital AI computing is not cheaper than land based within three years. Today, I believe launch costs are still well over $1000/kg.
