P. W. Singer says he is worried about the ethical implications of making “mistakes” with robots, but he also notes a scientist who says, “There’s no real social, ethical, moral issues when it comes to robots.

Then it’s just a product recall issue.” What do you think the ethical responsibility is when a mistake or malfunction related to robotics or drone warfare results in civilian casualties? Which of these two perspectives do you find more compelling, and why?
