What would happen if someone invented a machine that could create an exact duplicate of anything? That is the simple but remarkable premise of Damon Knight’s classic 1959 novel, A for Anything. “The Gismo,” as the machine is known, seems like it will end poverty and need forever. But of course, things are not that simple. Like any truly great work of science fiction, Knight’s novel boldly pursues the ramifications of his premise. What will people do if there is no longer any need to work for anything? What happens if this device is spread carelessly throughout the world (it can even duplicate itself!).
