I honestly don't know if you are an AI atroturfing bot. No, I am not being sarcastic. Given this is the top comment and there is no reply, here you go

A responsible human must always verify information. I DW as "secondary l" information source. For instance https://www.dw.com/en/why-does-ai-need-so-much-energy/video-...
tldr: chip immersion uses less water but is more expensive. Water evaporation is the opposite. Datacenters will use the cheapest they can get away with. Water is scarse; evaporated water is as unavailable as contaminated water. Read the information sources.
The explanation about chip immersion is wrong though. It's not a water-saving technique, it's for cooling dense racks more rapidly and maybe saving energy. That warm coolant still needs to be cooled before it goes back through the chips, likely the same way, evaporative cooling tower. Air cooling systems also involve a similar fluid loop, just doesn't go into the chips.
"Since the technology uses synthetic fluids, it requires significantly less water than other approaches." This is like saying that a new car radiator uses less water than an old water-based one, like yeah technically it requires water to work but you aren't boiling it away.
It does mention the real ways to use less water too, either chillers (which use way more power) or running in a colder climate.
I’m not a bot, but maybe I was too quick to not inspect my gut response. I guess I’ll look into it more, maybe this can be a learning experience.
FWIW the comment is just at +2 at the moment, I think it is just at the top of the thread because it is recent and has discussion.

This suggests a simple fix: charge more to the datacenters (not people) for the water, to make the other option competitive.
No need to throw baby with the ... erm, bathwater.
