Avi Parrack is a physics PhD student at Stanford and a researcher at Forethought, where he works on AI, space expansion, and governance. He is the lead author of a recent Forethought report on orbital data centers.

He joined Forethought’s Tom Davidson to discuss:

• What an orbital data center actually is, and why they’re suddenly being taken seriously
• Why the core case rests on cheaper energy from more intense and near-constant solar power
• Why orbital data centers hinge on SpaceX’s Starship bringing launch costs toward $100/kg or below
• Why cooling may actually not be a major issue
• Whether the inability to make repairs dooms orbital data centers
• Vulnerability of space data centers to kinetic attacks, and whether they would cause ‘Kessler syndrome’ debris cascades
• Why model-weight security might actually improve in orbit even as physical vulnerability rises
• If space becomes the cheapest place to scale compute and only SpaceX has the launch capacity, what the means for concentration of power, US–China competition, and the possibility of pausing AI
• Overall cost comparisons with terrestrial data centers
• The longer-run picture: when and how does the post-AGI industrial explosion spread to space?
