That's not the argument though. The argument is "it can be done, the methods to do it are known, but the claims about space being an optimal location to locate our AI datacenters are false and the tradeoffs and unit economics of doing it makes no sense compared with building a data centre on earth somewhere with power and water, preferably not too hot.

But for a more nuanced and optimistic take, this one is good and highlights all the same issues and more https://www.peraspera.us/realities-of-space-based-compute/

(TLDR: the actual use cases for datacentres in space rely on the exact opposite assumption from visions of space clouds for LLMs: most of space is far away and has data transmission latency and throughput issues so you want to do a certain amount of processing for your space data collection and infrastructure and autonomous systems on the edge)
