Perhaps the LLM itself, rather than the role model you created in one particular chat conversation or another, is better understood to be the “spirit.”
As a non-coder who only chats with pre existing LLMs and doesn’t train or tune them, I feel mostly powerless.
You realize in regards to only using and not training LLMs you are in the triple 9 majority right. Even if we only considered so called coders

Another way you can think of it is that when you're talking to an AI, you're not talking to a human, you're talking to distillation of humanity, as a whole, in a box. You want to be selective in what portion of humanity you are leading to be dominant in a conversation for some purpose. There's a lot in there. There's a lot of conversations where someone makes a good critical point and a flamewar is the response. A lot of conversations where things get hostile. I'm sure the subsequent RHLF helps with that, but it doesn't hurt anything to try to help it along.
I see people post their screenshots of an AI pushing back and asking the user to do it or some other AI to do it, and while I'm as amused as the next person, I wonder what is in their context window when that happens.
This is an aside, but my impression is that it is a very selective and skewed distillation, heavily colored by English-language internet discourse and other lopsided properties of its training material, and by whoever RLHF’d it. Relatively far away from being representative of the whole of humanity.
