Neill Blomkamp’s dystopian science fiction features all kinds of cool futuristic gadgets, one of those technologies are the medical devices known as “Med-Bays.” The Med-bay is seen frequently throughout the movie.
The Med-Bay essentially looks like a bed with a rotating fluorescent lamp attached — the device appears to have the ability to cure any ailment, from cancer, aging hair or facial wrinkles, to broken bones.
The idea is that a human who is registered to use the Med-Bay simply has to lie down on it, and then the Med-Bay will automatically scan for any diseases, ailments, or conditions, and automatically rebuild the body to remove the problem. Kruger (Sharlto Copley) even has his mangled face reconstructed and his heart restarted by one of the Med-Bays.
The movie doesn’t elaborate how the technology works, it could be based on some form of healing through electrical fields, and there has been evidence that existing technologies are capable of remarkable healing of physical and mental ailments (e.g. Pulsed Electromagnetic Field Therapy).
The Med-Bay can be used frequently and by many different sorts of people at once, without faulting, so movie fans have often pointed out the Med-bay as an analogy or a reference to privilege or given wealth, showing how the rich have extensive abilities to help the poor, regardless of whether or not they choose to.
