Because the complaints about the power and water usage of AI are mostly motivated reasoning. I don't like AI, therefore I'm going to find a reason not to like it. I Listen, if it's Greta Thunberg pointing out that AI datacenters use a lot of resources, yeah, I'm willing to listen. But when the voices saying "but what about all the water/electricity is wasting" is coming from individuals I know personally haven't previously given a shit about the planet or conservation or recycling and have made fun of me for reusing things instead of throwing stuff into the garbage, I'm sorry, but those complaints from those individuals fall on deaf ears. Not saying you are, just a theme I've noticed with people in my life.
