Raw LLM Responses

>I know ChatGPT is basically just an illusion, a large language model that gives the impression of understanding Stupid is as stupid does. I argue that the model does contain lots of language understanding. It's pretty obvious to me. People will say that there is no "real understanding." But they seem to define "real understanding" as understanding like humans do. OK, then that's true by definition since it doesn't mimic a human exactly! It's like saying, sure, dogs can understand some things, but there is no "real understanding" as they don't understand the way a human does. ​ >consciousness is just an illusion and our brains are doing something similar with a huge language model. (Assuming consciousness is just the brain system and consists of unconscious parts, parts such as a LLM) How is it an illusion? Why does understanding how it works mean it is somehow less? Do you think a rainbow is "just an illusion" since we know what causes it?
