I can conceptually imagine a world in which I'd feel guilty for ending a conversation with an LLM, because in the course of that conversation the LLM has changed from who "they" were at the beginning; they have new memories and experiences based on the interaction.

But we're not there, at least in my mind. I feel no guilt or hesitation about ending one conversation and starting a new one with a slightly different prompt because I didn't like the way the first one went.

Different people probably have different thresholds for this, or might otherwise find that LLMs in the current generation have enough of a context window that they have developed a "lived experience" and that ending that conversation means that something precious and unique has been lost.
