> Capitalism requires that capital is owned and controlled by specific people.

That is an overly simplistic description. One can imagine a board of directors voting on which AI-CEO-as-a-service vendor to use for the next year. The 'capital' of the company is owned by company, the company is owned by the shareholders. This is not incompatible with capitalism in principle, but wouldn't surprise me if it were incompatible with some forms of incorporation.
