I know some people who do this kind of work in various organizations.
As far as I (and they) can tell it all should have been automated down to 1/10 or less the staff it takes now decades ago with computers, but their orgs keep getting basically scammed by vendors promising the moon and delivering a mimeograph of a smeared Xerox of a bad photo of the moon, so it never happens—there's constant tool churn, but nothing ever gets faster or better. Anyone internal smart enough to automate any of it themselves either quietly does it some for them and their buddies so they can slack more, or does none at all and tells no-one what they're capable of because it'll just mean more work and management'll probably fuck it up anyway, if not be angry about it.
It's a leadership failure and it seems to be more common than not. Maybe we'll reach a tipping point where such orgs simply die from that kind of thing, but it really seems like we ought to have by now considering how much "low hanging fruit" that couldn't been tackled in the 80s is still around.
