The role of CEO is going to be different at every company. For many large companies, I imagine most of the role is managing relationships, both internal and external. You have very ambitious and accomplished heads of different divisions that are all fighting for resources, and also probably jockeying for your position. You have to be able to communicate with legal, people ops, finance, comms, marketing, sales, product/engineering, etc, and know enough about each such that you could make decisions about each and hire a replacement for the head of those departments should any of them leave. You also have to manage partnerships with suppliers, manufacturers, contractors, investors, the media, regulators, and politicians. And on top of that, you have to manage the relationship with your employees and convince them that the company is headed in the right direction and they should stay and work hard.<p>No AI that I've heard about is able to manage any human relationship.
