water usage is not the same as water consumption, the meme is funny as shit but some people seem to genuinely think the water that servers use for cooling goes nowhere and just is destroyed and can't be used again for anything else
ChatGPT, and AI in general, uses lots of water for cooling when generating responses. For example, a single response can use 0.3 watt-hours (~1,080 joules) of energy, producing a lot of heat. Longer outputs require more energy.
