The Final Upload: Why the Future of Data Centers Is in Space - Philip Johnston, CEO and Co-Founder, Starcloud

In this episode, I sit down with Philip Johnston, co-founder and CEO of StarCloud, a pioneering company at the forefront of orbital data centers. Philip makes a bold prediction: within 10 years, all data processing will be in space—and he’s on a mission to make that happen.

We dive into the game-changing advantages of space-based data centers, including unlimited solar power, passive cooling, and scalability—all of which could make terrestrial data centers obsolete. Philip breaks down the economic and engineering realities of launching massive compute infrastructure into orbit, tackling key challenges like thermal management, radiation shielding, and space debris.

He also shares insights into:

🚀 The role of optical communications and its potential to overcome bandwidth limitations.

🌍 The environmental impact, explaining why space-based computing is actually more sustainable than Earth-based data centers.

🛰️ The first steps—StarCloud’s upcoming launch and how their modular approach will scale computing in space.

🤖 The future of robotic maintenance and how humanoid robots could soon service infrastructure in space.

🧠 And yes, we even get into Dyson Spheres and Matryoshka Brains—the ultimate endgame of intelligent civilizations.

This conversation is a fascinating deep dive into the future of computing, energy, and space infrastructure. If you think the cloud is the future—think bigger.
