I don't think a co-founder would just jump ship just because. That would be very un-co-founderish.

I would also assume that he earns enough money to be rich. You are not a co-founder of OpenAI if you are not playing with the big boys.

So he definitly wants to be in this AI future but not with OpenAI. So i would argue it has to do with something which is important to him so important that the others disagree with him.
