Starcloud plans 88,000 satellites to move AI compute into orbit

In a video conversation, Philip Johnston, cofounder and CEO of Starcloud, explains a plan to relocate AI data centers from Earth to space using a constellation of 88,000 satellites. The discussion covers the technical hurdles of cooling powerful chips in orbit and shielding them from radiation, as well as how SpaceX's Starship could reduce launch costs and make orbital compute economically viable.

Johnston predicts that within a decade, most new compute capacity will be built in space rather than on Earth. The conversation also touches on broader themes including the Fermi paradox, AI risk, and humanity's long-term expansion into the cosmos, including a speculative mission to Alpha Centauri.
