Summary: The water usage of AI data centres is not a significant environmental issue. While data centres do use water, primarily for cooling, their water consumption is minimal compared to other industries and daily activities. The concern is often based on misconceptions and misleading statistics, rather than a comprehensive understanding of the data and the broader context of water usage.

I see this brought up a lot, and while I understand the concern, I'm always a litle skeptical that it's what people trot out. Keeping this so I can refer back to it, and for further investigation.

There's folk I know who seem to thnk they're experts on how the immune system works, and who offer terrible unsolicited advice any time someone has a cold, or the flu, or whatever. It almost always relates to crap based off their own health-freak bias founded in ignorance.

This should be a good article to start with to tackle such bollocks.
