"When this story first appeared, the fans detested it. I read it over, perplexed by their hostility, and could see why: it is a superdowner story, and relentlessly so. Could I rewrite it, I would have it end differently. I would have the man and the robot, i.e. the ''fasrad'', form a partnership at the end and become friends. The logic of paranoia of this story should be deconstructed into its opposite; Y, the human-against-robot theme, should have been resolved into null-Y, human-and-robot-against-the-universe. I really deplore the ending. So when you read the story, try to imagine it as it ought to have been written. The fasrad says, 'Sir, I am here to help you. The hell with my sales pitch. Let's be together forever.' Yes, but then I would have been criticized for a false upbeat ending, I guess. Still, the ending is not good. The fans were right."〔Second Variety, Citadel Twilight, 1991, p. 413, ISBN 0-8065-1226-1〕
