Building those datacenters and keeping them operational involves massive amounts of highly skilled blue-collar labor.

You seem to suppose the building of those datacenters - even the power plants behind them - won't soon be automated. Almost as if robotics isn't happening.

I don't get it, why would operating a datacenter needs massive amount of high skilled blue-collar labor. Datacenters are resource hungry. With so much automation in place I don't think there would be a need for large pool of labor.
