> to cut out all of the people that never really had an interest in CS

I had assumed most of them had either filtered out at some stage (an early one being college intro CS classes), ended up employed somewhere that didn't seem to mind their output, or perpetually circle on LinkedIn as "Lemons" for their next prey/employer.

My gut feeling is that messy code-gen will increase their numbers rather than decrease them. LLMs make it easier to generate an illusion of constant progress, and the humans can attribute the good parts of the output to themselves, while blaming bad-parts on the LLM.
