While automation is removing some jobs, we are far from a fully automated society. I obviously don't know about the specific job markets where your data centers are, but in general, the ones having the hardest time finding a job aren't the ones with years of work experience in running data centers.

They might have to retrain and if they live in a small town they might have to move/commute to find something new however. This can be hard enough for some people that they won't be happy about it.

In the end, I think it's hard to argue that we should keep being inefficient just to save jobs. History haven't been nice to that kind of companies.
