All of the irrigated golf courses combined use more water than all of the US data centers combined.
DCs, new golf, new homes, new alfalfa, new ranching - the math isn't there.
Tech people saying ignore the water problems are saying implicitly that AI, despite showing up late in line for access to a resource that's an old, old problem in the western US, is more important than hearth and home considerations fighting for the same dwindling resource.
The average western farmer/rancher, their own judgement and contributions to this problem aside, definitely love coastal tech people sniping their pre-colorado compact water rights via all that goes into getting water rights like that.
same if increasing alfalfa farming was increasing significantly
it's harder to stop something that already exists (shutting down existing golf courses or alfalfa farms has consequences for the local communities) than to stop something from coming into existence in the first place
