What? Surprised? Wasn't the worst thing about wishes the moment when they come true? At least, that's been so in the folklore of any culture I know of, there's always a story of wishes being granted, and then turning out to be something the wisher didn't intend. There's something deeply ingrained in our collective conscience about this - and I'm not surprised the motif has made its way into SF.
