SpaceX's $1.25 trillion xAI acquisition signals ambitions to launch orbital data centers, joining Google and startups like Lonestar and Starcloud. Projections suggest 2035 timelines for cost-competitive launches, assuming $200/kg payloads via Starship.

Even with radiation and cooling solved, satellite scalability remains a fantasy. Training frontier AI requires hundreds of thousands of GPUs—launching equivalent satellites risks Kessler syndrome and orbital debris catastrophes.

In-space upgrades are impossible, demanding entirely new satellite fleets per hardware cycle. Meanwhile, ground-based solar energy costs keep falling, making space data centers economically obsolete before they even launch.

Why the hype? SpaceX eyes an IPO, while xAI burns cash daily. Investors bet on selling 'up' before reality sets in—long timelines offer ample room for speculation without accountability.
