Steven Poole – On algorithms

Steven Poole – On algorithms: More recently, Gary Marcus, professor of psychology at New York University, offered a vivid thought experiment in The New Yorker. Suppose you are in a self-driving car going across a narrow bridge, and a school bus full of children hurtles out of control towards you. There is no room for the vehicles to pass each other. Should the self-driving car take the decision to drive off the bridge and kill you in order to save the children?

What Marcus’s example demonstrates is the fact that driving a car is not simply a technical operation, of the sort that machines can do more efficiently. It is also a moral operation. (His example is effectively a kind of ‘trolley problem’, of the sort that has lately been fashionable in moral philosophy.) If we let cars do the driving, we are outsourcing not only our motor control but also our moral judgment.
