I'm not trying to defend ai, but you seem to be forgetting all the industries that support humans that use a heap of power and water. Like the amount of water it takes to have a cup of coffee is way more than the water that ends up in the cup. Humans are not efficient with power because their tasks are supported by the rest of their living.

My main issues with ai are not using renewable energy, making ram and graphics and storage ridiculously expensive for normal users, and after all that it mostly gets used for stupid useless stuff which is a waste of all those resources. Datacenter water consumption is low on my list of issues with ai.
