Robots take on, without complaint, the tasks we can't be bothered with. Take the drudge out of our time-tight lives. Clean our floors, build our cars, have sex with us. All without a blink of their glowing eyes. The ultimate submissives, they follow our bidding unquestioningly. They can be custom-designed to cater to your every twisted desire and they'll never grass you up. Plus you don't need to feed, pay or compliment them. In theory, man and robot sounds like the perfect combination; all the pleasure of human contact without any of the hassle. But as droids get ever more advanced, our relationships with them become complex.
