I interviewed for a position at a data center company near Sacramento (didn’t get it). The facility was nearing construction completion and it was a VERY fascinating tour.
People have NO idea of what is behind the scenes to keep these bits flowing. It is staggeringly complex and sophisticated.

Cool - my first programming assignment was that bank facility - IBM 3083 MVS plus a 370-158 for R&D - did some work on another IBM machine there
Those were great days - learned a tremendous amount
