How hard is it to build orbital data centers, actually?

This article explores the technical challenges of building orbital data centers, including launching, heat dissipation, radiation, and latency. SpaceX envisions a constellation of 1 million satellites to power GPUs for data center services, with Elon Musk stating much of the technology is already developed for Starlink. While the physics are sound, the economics and massive technical hurdles remain a subject of debate among industry experts.
