One aspect of sex doll hobbies is that real women (and men) have difficulty getting the perfect doll. Some women have beautiful faces, hair or numbers. But few women have all of these qualities in one package. If some dolls are not perfect, we tend to ignore the same flaws as real people. Even if the doll reaches automatic movement and some form of artificial intelligence, no doll will replace humans. On the other hand, no one can provide perfect no-baggage for the doll. Dolls do not have human support requirements, food, drinks, health care, etc.
