Or, just saying, we should eat babies because they are abundant and full of healthy nutrition for adult humans. [1]

Just because an idea has some factors in its favor (Space-based datacenter: 100% uptime solar, no permitting problems [2]) doesn't mean it isn't ridiculous on its face. We're in an AI bubble, with silly money flowing like crazy and looking for something, anything to invest it. That, and circular investments to keep the bubble going. Unfortunately this gives validation to stupid ideas, it's one of the hallmarks of bubbles. We've seen this before.

The only things that space-based anything have advantages on are long-distance communication and observation, neither of which datacenters benefit from.

The simple fact is that anything that can be done in a space-based datacenter can be done cheaper on Earth.
