> Any one noticed how Sam sometimes intentionally tries to attack his own work? For example, he has said GPT-2 was very bad, GPT-3 was bad, and GPT-4 is okay. He also fed the AI doomers by talking about AGI dangers and how the world needs to watch out for a future AI catastrophe.

That is the opposite of criticism. It all translates to "GPT-(n+1) is going to be super awesome".
