Question: In their goal of designing "moral machines," Wendell Wallach and Colin Allen argue that we do not need to develop artificial moral agents that have full moral agency. We saw that they believe that machines need to have only functional morality to be able to accomplish their objective of building moral machines. What do Wallach and Allen mean by "functional morality" and how is it different from full moral agency? Do you agree with their claim that questions about whether AMs can be full moral agents actually distract from the larger goal of researchers in machine ethics who aim to build machines that are capable of "acting appropriately in morally charged situations?" Explain.
