I don't remember this being the narrative at all. Almost as soon as LLMs could produce useful code the narrative I was hearing among devs was "Seniors + LLMs means you'll need less juniors."

And the narrative from companies (sometimes requiring the smallest amount of reading between the lines) is "You'll need less human employees, period."
