SpaceX CEO Elon Musk says AI compute in space will be the lowest-cost option in 5 years — but Nvidia's Jensen Huang says it's a 'dream'

Elon Musk argues that terawatt-scale AI computing will soon be impossible to power and cool on Earth and must move to orbit. But despite abundant solar energy and radiative cooling in GEO, launch mass, radiation-hardening, and networking challenges make such space-based data center only a distant dream.
