Why Underwater Data Centers Are a Fever Dream and Space Compute Is Science Fiction

The Unconventional Deployment Myths — Submerged, Orbital, and Other Expensive Distractions

Every few years, someone publishes a breathless article about Microsoft’s Project Natick — the subsea data center experiment — as evidence that underwater compute is the future. Every few years, someone proposes space-based data centers as the solution to terrestrial infrastructure constraints. These ideas travel well on LinkedIn. They travel nowhere in the real world.

I want to be precise about why. Not dismissive — the engineering behind both concepts is genuinely interesting. But interesting engineering and viable infrastructure architecture are different things, and the AI era cannot afford to confuse them.

Project Natick: What Microsoft Actually Learned

In 2018, Microsoft deployed a 12-rack, 864-server data center pod in 117 feet of water off the Orkney Islands in Scotland. Project Natick Phase 2. They retrieved it in 2020. The results were published, celebrated, and then quietly filed away.
