We were discussing about the current state of affairs. Of course I am not stupid to think what I said in my original reply if we are taking about an LLM trained on “perfect data”
But that was not the premise.
Fwiw, ChatGPT-4o can write a lengthy essay as to how pigs don't have wings and couldn't fly to the moon even if they did, but if we're more interested in them being nothing more than just a statistical model and that those mere statistics can't possibly result in something that looks like reasoning then we've got to disregard the fact that it "knows" that pigs don't have wings.
Of course pigs having wings is a stand in for whatever else wrong thing that LLMs might "believe", so I agree it's very important for everyone that uses an LLM to understand their limitations especially around hallucinations, but where there are books written about how flat the Earth is and are in the training data, the current state of affairs is that ChatGPT and Gemini both know it's not flat. That Google search AI results, which is a different model, is telling users to use glue on pizza, or to drink urine only serves to say that Google Search's bot using Reddit as unannotated training data is as representative of LLMs as a human with a mental/cognitive disorder.
