And what’s really silly is just how little energy costs are as a % of total data center costs(below 10%). Redundancy costs alone would be multiples of that. @SpaceX

Quoted context

These are the quoted author’s words.

Elon’s pivot to space data centers has the exact same smell as Full Self Driving being “next year” since 2016. The idea sounds amazing. The physics does not. On Earth, data centers dump insane amounts of heat into air and water. In orbit, there is no air to carry that heat away. You are basically stuck radiating waste heat into space, which means enormous radiator surfaces. AI data centers are not cute satellites. They are power hungry GPU furnaces. Then comes maintenance. GPUs fail. Power systems fail. Cooling systems fail. Networking fails. On Earth, technicians replace parts constantly. In orbit, every failure becomes dead mass or a space mission. Could space compute happen eventually? Sure. But selling it as an imminent pivot is classic Musk timeline theatre. Maybe in ten plus years.
