Each argument could easily fill a book. Some valuable insights are discussed in the linked article, but most of the evidence comes from a series of research papers demonstrating that LLMs perform poorly when confronted with out-of-training distribution prompts. For example, even state-of-the-art LLMs can fail simple tasks like counting the number of "r" letters in the word "strawberry" or fall victim to the reversal curse (e.g., LLMs trained on "A is B" often struggle to deduce "B is A").
