2-3x sounds like a very low estimate.

There’s so much data center capacity being built all over the Earth. Thousands of large projects across US / China / Europe / Middle East. It would be astonishing if something that’s never been done before could be so cost-competitive immediately.

Starlink wasn’t the first time LEO communications constellations were attempted. Multiple 1990s projects did it (Iridium, GlobalStar…) and went bankrupt.

It took 30 years to make the concept work. SpaceX investors seem to be assuming the space data center business will be immediately viable.
