As a long time LLM enjoyer I just want to mention https://generative.ink/posts/simulators/ as I think it's by far the most insightful take on the GPT LLMs even though it was from before ChatGPT. It's better than blurry jpeg and stochastic parrot etc.
I think that article is misleading, because a simulator has rules. An LLM is better thought of as a storyteller, because at best it's going to follow whatever implicit rules there are very loosely and let you make rule changes of your own, more like Calvinball. Also, whatever loose rules it has are more literary than mathematical. Plot twists often work.
No, it is clearly not, and that is a very easily testable hypothesis.
Thank you for sharing.
