Compute Wants to Leave Earth: A Manifesto for Orbital Infrastructure
McDonaghMatthew · x · 2026-09-01
Matt McDonagh publishes a manifesto arguing that orbital compute will become one of the defining infrastructure projects of the next decade, explaining why Earth is becoming the expensive option.
Core Arguments:
- Redesign, Not Relocate: The goal isn't strapping a Virginia data center to a rocket, but redesigning the entire compute stack (power, cooling, networking, hardware) around orbital advantages.
- Earth's Disadvantages: AI compute is an infrastructure project limited by the semiconductor supply chain. Building on Earth faces physical limits and rising costs.
- Orbital Advantages: Space offers natural cooling environments (though heat transfer differs), potential unlimited space, and solar power. While challenges like radiation hardening and repair exist, they can be solved through architectural redesign.
- SpaceX's Role: The vision depends heavily on SpaceX transforming orbital access from a launch service into a global industrial logistics network.
The thesis suggests this will begin with inference, agents, and space-native workloads, driven by Earth's physical constraints.
