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?
