It's completely trivial when you compare it to livestock agriculture's water usage (and even more trivial when looking at overall environmental damage), yet mysteriously 99% of people clamoring against GenAI's water usage have never opened their mouths about that. Or ever skipped a hamburger due to it. It's a joke. There are a hundred other good reasons to criticize GenAI, go pick one of those. The truth is that people are embarrassed of the real main reasons they dislike GenAI, yet they shouldn't be. Unlike this one, they're perfectly valid reasons.
I've known this for a long time and ironically this very article proves me right. The article is straight LLM slop, right from the mouth of GPT, Gemini or Claude. It's overt. Out of all 30 articles on the current HN frontpage, this one is by far the highest % LLM-written of all of them - I took the time to skim through each of them. This tells you all you need to know. With this in mind it's poor behavior to accuse GP of all people of astroturfing.
