Climbing the Kardashev Scale: SpaceX AI Satellites and the Terafab

In a SpaceX studio sit-down at the company's Bastrop, Texas facility, Elon Musk and Starlink engineer Ian join a host to connect the dots between Starship, Starlink solar technology, and a bold plan to put AI compute in orbit. Musk frames the effort using the Kardashev scale, arguing that humanity currently harnesses less than a trillionth of the sun's power and must move to space to ascend it. The team outlines three limiting factors to solve at scale, mass to orbit, solar power, and chips, and unveils a draft design for a SpaceX AI satellite delivering roughly 150 kW peak power. The conversation escalates from launching thousands of orbital compute satellites to building a 100-million-square-foot 'terafab' chip factory, and ultimately to lunar mass drivers that could fling AI satellites into deep space, scaling civilization's energy harvest toward a terawatt per year and beyond.
