Probably a fair bit of hubris, sure. But right now it is not possible or legal to operate a company without a CEO, in Norway. And I suspect that is the case in basically all jurisdictions. And I do not see any reason why this would change in an increasingly automated world. The rule of law is ultimately based on personal responsibility (limited in case of corporations but nevertheless). And there are so many bad actors looking to defraud people and avoid responsibility, those still need protecting against in an AI world. Perhaps even more so...
You can claim that the AI is the CEO, and in a hypothetical future, it may handle most of the operations. But the government will consider a person to be the CEO. And the same is likely to apply to basic B2B like contracts - only a person can sign legal documents (perhaps by delegating to an AI, but ultimately it is a person under current legal frameworks).
