Data centers create some construction jobs while they are being built but not much after that. A few people to keep an eye on things, swap out failed equipment, accept deliveries.
I think the news is misleading people on the number of jobs it will create. I mentioned data centers not creating many jobs to my dad, a news junkie in Michigan, and he said he read it would create over 1k jobs. That must have been including temporary construction jobs.
Google's data center complex in Council Bluffs, IA is one of the largest in the world and it employs ... 250 people excluding temporary construction/expansion jobs.
