Opinion Alert.First, the article states this is not the most powerful computer available. It is a pathfinder that could lead to more powerful computers.Second, it is a trade off between hardening and cost.Third, it is more powerful than any other computer on board. It will speed research on the station if it works.
Wouldn't cooling capacity be a massive problem too? The radiators have a limited capacity and computing generates a lot of heat. To the point that large data centres are being moved to the Arctic.
Short phasing time this opportunity.

Why would they ship that set of grid fins to the East coast?
