> My reaction when I hear this is that those people are being paid entirely too much money if an LLM can do their job.

That feels like such an unnecessarily cynical view to me. First, parent comment didn't say they are using LLMs to "do their jobs". Frankly, I feel that if you're a knowledge worker and aren't using LLMs at least part of the time, you're likely being inefficient. E.g. LLMs don't replace my skill as a software developer, but they sure make it faster to learn new libraries/technologies faster.
