But AIs don't, and corporate officers must be persons (natural persons, even -- a corporation can't be a corporate officer.)

A person could be made a mediator of AI to overcome it.

Many CEOs are already just trying to operate as a share price optimization algorithm. They don't choose to inject human values into their organizations.

> ...operate as a share price optimization algorithm...

That in itself is not so bad, as extremely long-timeframe constraints (say, >50 years) upon such an algorithm could conceivably be consonant with current decision-making behavior that externalizes many input costs (employee overtime, environmental damage, etc.). Running the algorithm to pay out in very short timeframes (a month to a year) due to most CEOs' anticipated short tenure is what seems to cause undesirable optimizations.

That you don't share their values does not make them non-human

That they are human doesn't mean they cannot be a threat to humankind. ;-)
