Large corporations are not really very like AIs at all. An Artificial Intelligence is an intelligence with a single utility function, whereas a company is a group of intelligences with many complex utility functions. I remain unconvinced that aggregating intelligences and applying the same terms is valid - it is, roughly speaking, like trying to apply chromodynamics to atoms and molecules. Maximising shareholder value is also not a simple problem to solve (if it were, the stock market would be a lot simpler!), especially since "shareholder value" is a very vague concept. In reality, large corporations almost never seek to maximise shareholder value (that is, in theory one might, but I can't actually imagine such a firm). The relevant terms to look up are "satisficing" and "principal-agent problem".

This rather spoils the idea of firms being intelligent - the term does not appear applicable (which is, I think, Eliezer's point).
