The purpose is comedy, haha, but the need I have is to realistically estimate when companion robots (clean) will become conversational. Some of the robots in the book are more mechanical-looking. Some more "human-like," meaning: difficult to discern from humans. It's all for the purpose of serving the story, and I can see your point about where the market is. That is helpful as I can see that if these nonsexual companionship robots come to exist, it will be well after every other area is dominated by more useful robots. Thanks!
