People need to understand that OpenAI is not a publicly traded company. Sam is allowed to be outrageously optimistic about his best case scenarios, as long as he is correct with OpenAI's investors. But those investors are not "the public", so he can publicly state pretty much anything he wants, as long as it is not contradicting facts.

So he cannot say "OpenAI made 20B profit last year." but can say "OpenAI will make 20B revenue next year." Optimism is not a crime.

I am not a lawyer, but it is possible he can say whatever he wants without consequences to public because OAI is not a public company.
