Part of GM's downsizing means selling off thousands of out of date industrial robots. I imagine one working for a carnival as the engine for a wicked cool ride. But, as the lyrics go, how does it feel? Things to play with include rudimentary intelligence, a high level of strength and danger, working for carnies, giving joy to kids, and missing all the other robots it used to work with at the factory.
Also, could be a parable of retrained, out of work, union employees. Or a general midlife crisis moment for the robot.
