I am not the author but I have used that quote before, and no, I mean it literally. I would prefer any words that came from your own brain over the output of a statistical model. I don't mind if it's short, or didn't take much time, or doesn't have much thought put into it, I want it to be yours. The subtle mistakes in how my interlocutor perceives the world and communicates themselves are the entire point.
I had a case in my job of an HR guy that was so bad a communication everything was super confusing and we always had issues and tension.
Once GPT came out he clearly just copy / pasted LLM output and I was very conflicted because it felt insulting but it was the first time I was actually able to understand what he intended to say...
I sadly would prefer LLM output over prompt because I'm pretty sure the prompting was a process with him he would prompt, get a bad LLM output, seeing the LLM wasn't understanding force him to clarify and we ended up with actually understandable content.
I would rather my reports tell me to fuck off than to generate something telling me to fuck off in polite but insincere terms full of emojis and em dashes. Honesty is valuable.
I too would much rather that, because then I get to know them as unhelpful whining complainers and fire them. That's not a great outcome for that person though.
