This is false. Evaporative cooling systems consume significant amounts of water and do not reuse it. They can't anyway, recondensing the water would release all the heat they removed by evaporating it.

> Data centers use very little water, right down to none if they want. And state-of-the-art hyperscale data centers really are operated by AIs.

There are many, many reasons to oppose datacenters. Not the least is they're there to drive inequality to ever-greater heights and they're 21st century version of the toxic waste dump (put 'em where people are weak and marginalized).

But water use is a very simple argument, and sometimes you have to pound on those to get through to the general public that's not immediately affected.

Source on that water claim? Everything I've seen suggests the opposite.
