Perhaps you ought to watch the movie, "Bicentennial Man". Watch the scenes which feature Galatea, who is a female android. Don't worry, the scenes aren't sexual. At the end of the movie, they show her as she is, acting and looking like a human, well, the character is portrayed by a real human female, obviously. Though, the potential for human-like androids, is awesome. By the way, they are not a colossal waste, especially considering all of the advantages to them, which I have mentioned throughout this thread.
