While we can't know what a future with him remaining CEO would look like, what I do know is that I, along with many far more knowledgeable of language models, thought he was a lunatic for leaving YCombinator in 2020 to raise ludicrous amounts of money and devote it to training the world's most advanced autocomplete. Does that mean he still possesses seemingly prophetic insight into the future of generative models? I have no clue. All I know is that many knowledgeable people (and myself) vastly underestimated him before and we were dead wrong. Even if OpenAI's decision is wrong and he possesses such level of insight, it doesn't matter because it would mean he doesn't need them. If he's a one-trick pony whose vision for the future ends at 2023, then they made the right decision.
