Saying “they need to be written down” and then immediately negating that point is absolutely terrible writing. And even a casual contract, like OpenAI’s where they literally have stated in writing for years what their “contract” is, would not be hard to understand.
Musk is a moron and this is clearly a ploy to gain some sort of control over OpenAI, but OpenAI is breaking what they said their goal was. I know that doesn’t mean there’s a contract there, but it has been written down numerous times what he’s claiming “the contract” is.
