Yes, this vision has been thrown about, but they thing is, even if the wildest predictions were to come through, the employment generated by these large-scale datacenters is a small fraction of the jobs lost in other industries. And most of these jobs are relatively low-paying ones such as perimeter security, replacing faulty servers etc. A far cry from, say, the hordes of engineers employed by the telecom sector during the boom years.

Sure, they may indirectly generate a lot of jobs, but you don't need to live next to (or even in the same country as) an Amazon, Google, or whomever's, gigantic datacenter in order to use it.
