Making it a stupid design, yes.

Edit: putting your massive heat generating data center (beyond what most DCs will do) in support of AI in Texas is stupid.

Closed loop systems absolutely have other options in design, which ive mentioned in another comment chain.

As terrible as they are as companies, meta, apple, and others have made much more appropriate decisions - like locating their big load DCs in cold climates, partnering with the locale to make use of the heat being generated, removing the need for power to be used to perform those tasks - making them not only efficient designs, but compared to putting a DC in Texas like a dipshit (or LA, or NV, or anywhere else with a hot climate), makes the whole thing better for the environment.

Yes, its a stupid design.
