Sure, I think they're neat. I've been inside a few smaller ones but not any true modern hyperscaler style ones. They're big buildings with cool security systems, power setups, HVAC setups. It'd be fun to see inside. Nothing on the level of a nuclear plant, of course, but about as cool as it'd be to tour any big industrial facility, I'd imagine.
Which isn't to imply I'm "pro data center" or whatever but if they're going to build them it'd at least be nice to show people inside. This seems like pretty basic PR stuff that developers of large industrial facilities (again, nuclear plants, hydro dams etc) figured out ages ago.
