The extremely dumb thing here is that the water use is totally fine. California alone uses ~11 TRILLION gallons of water per year for farming. And so what, that water cycle returns via precipitation (assuming we don't go so hard to fuck up the aquifers, but you know what I mean). The water is fine. Plus that farm water runoff is even kinda hazardous, with pesticides etc. It's still fine
This is a totally recyclable resource. You can probably use it to water plants after it's been through the data center, or it may have just evaporated away as part of the cooling process
Meanwhile, the obvious dart to throw is the fact that the power need is absolutely ridiculous and only growing, leading to every major tech company investing extensively in energy tech. Eventually they will become a new generation of utilities that supply power (and compute) to everyone. So the opportunity is to force them to reinvent energy in a clean way rather than, say, burning an utter shitton of oil to do it
