I agree entirely, and I think it's worthwhile to note that it may not even be the LLM that has that behavior. It's the entire deterministic machinery between the user and the LLM that creates that behavior, with the system prompt, personality prompt, RLHF, temperature, and the interface as a whole.

LLMs have an entire wrapper around them tuned to be as engaging as possible. Most people's experience of LLMs is a strongly social media and engagement economy influenced design.
