>If people are using it presumably they're getting some value out of it which means that most objections to datacenters are NIMBYism and not some kind of principled stance.

No, one does not follow from the other. I might campaign against the building of a road because I believe the funds could be better spent on something else. If the road is built, am I a hypocrite for using it? No. The road is already there. Whether I use it or not, the funds are already spent. I may as well use it.

Something can be positive under a narrow lens, and a negative under a broader one. There's no hypocrisy in acknowledging both realities.

>Datacenters are fine.

Datacenters and AI are distinct things. Someone can be in favor of one and not the other, with no contradiction.
