I have some idea, yeah. Call centers employ a lot of people, as do book-keeping, HR and retail checkouts. It’s not going to code or engineer any time soon, taking a statistically decent guess at what you do, but the percentage of the non-Lemmy population that does that sort of work is tiny.
Manufacturing depends heavily on the specific job. Obviously machining is easily automated (if not the loading and maintenance of the CNC machines themselves), and basic assembly can be too, but once non-rigid or variable materials come into the picture it all gets harder, and any kind of uncontrolled environment seems to make it impossible.
