Is there a jurisdiction anywhere in the civilized world that doesn't legally require "natural persons" (legal jargon for a flesh and blood human being) to fill the positions for corporate officers? Those corporate officers can face civil and criminal liability for any wrongdoing even if they are merely meat proxies executing the commands of an AI. Even if some group of fools were willing to sign up blindly to be corporate officers, they would probably betray the mastermind at the first sign of legal trouble.
