It's a lot better than that. OpenAI is just very good execution of publicly available ideas / research, with some novelty that is not crucial and can be replicated. Moreover, Altman himself contributed near zero to the AI part itself (even from the POV of the product). So far OpenAI products result more or less spontaneously of what LLMs where capable of. That to say that there are crucial CEOs sometimes, like Jobs was for Apple. CEOs able to shape the product line with their ability to just tell apart outstanding from meh things, but this is not the case.
