WorkThe story, in brief

How would AI data centers in space even work? A former NASA robotics chief explains

Nobody is talking about where the next 10 exaflops of compute lives. Spoiler: not on Earth.

Why it matters

As AI infrastructure demands push against terrestrial power and cooling limits, space-based data centers are moving from sci-fi to serious engineering discussion—with real implications for where the next generation of AI training happens.

The key facts

9 to know

  1. Space-based power generation + heat rejection model eliminates Earth-bound thermal/electrical constraints

  2. Only data transmission returns to Earth, reducing infrastructure footprint

  3. Former NASA robotics expert lends credibility to feasibility discussion

  4. Addresses fundamental AI capex bottleneck: power and cooling, not compute itself

  5. Shifts long-term AI infrastructure strategy conversation beyond terrestrial data center buildout

  6. Space data centers could eliminate heat rejection problem by radiating directly into space

  7. Only data payload would return to Earth, reducing transmission constraints

  8. Former NASA robotics chief consulted on feasibility

  9. Addresses fundamental infrastructure bottleneck: power density and thermal management on terrestrial grid

The Emerging M&A Map For AI Agent Security

As agents move from pilots to production with real system access, enterprise security models are breaking. The M&A map is forming around who controls agent permissions, monitoring, and governance — a new class of identity management problem that practitioners need to architect for now.

AI privacy budgets: Ask for the calculation, not the claim

Enterprise AI buyers are accepting privacy budget numbers without verification. This deep dive explains what questions to ask vendors about federated learning privacy claims, and why the gap between contractual promises and operational evidence is where real exposure lives.

Andrew Kelley Interview: Why He Built Zig, Banned AI Contributions, and Moved Zig off GitHub

Open-source governance is shifting in response to AI-generated contributions. Zig's formal ban and migration off GitHub signals broader industry concern about code quality, maintainer burden, and the cultural impact of automated submissions — a flashpoint for how AI changes the work of software development.
