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.

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.
