A shy man with a stammer, Macklin's professed preference for robots over Humans was based largely on their being "uncomplicated". Though the other staff writers teased him about his predictable subject matter, Macklin took it in stride and his work was good enough to secure a contract to produce a novel about robots.
When editor Douglas Pabst was unwilling to print Benny Russell's story about a black captain of a futuristic space station, Macklin suggested altering the story to make it a dream of a present-day man. Macklin once sold a novel to Gnome Press. (DS9: "Far Beyond the Stars")
