Write a philosophical treatise analyzing the concept of moral agency in artificial intelligence. Compare and contrast functionalism and interpretivism in the context of AI decision-making. Specifically, address the following: If an autonomous vehicle makes a split-second decision to sacrifice a passenger to save a group of pedestrians, can the AI be held morally responsible? Discuss the necessity of consciousness for moral agency and evaluate the framework of 'forward-looking responsibility' versus 'backward-looking responsibility' in the context of autonomous algorithms.
