I’m more surprised that it’s not believable for some of management depending on how process driven there job is.

I’ve definitely had roles where I sadly realized I’m automating the QA person next to me well before LLMs were mainstream.

In my experience I think, you would automate enough of a mid manager role that upper management doesn’t care for, and whatever left over responsibilities that couldn’t be automated is split between a high level IC and the next above. Then the bureaucracy sells is as a success.
