Time for artificial intelligence to get its own code of conduct

For example, what if a self-driving car is programmed to get us as quickly as possible to the airport, but is not concerned with how many pedestrians are injured along the way? Or, say an AI program identifies how to cut costs in a large healthcare system, neglecting to account for how the most vulnerable groups would be affected. As AI becomes responsible for ever more decisions, it will achieve goals more quickly without taking into account the other things that are important to our species.
