I was intrigued by the implications that the Rat Thing created. A machine with biological components? In a way it is a feat of genius. In another way, it's a cruel, damaging proposition.
Creating a machine with biological components brings up a few unanswered questions as to its origin and function. First of all, where do these organs come from? It's apparent that the Rat Things have organic components derived from canines of sorts. Have these organs been ripped out of living animals to empower these new mechanical creations? If so, that certainly says something about the ethics and animal rights of the time. Taking organs from a recently deceased older dog probably wouldn't work because the organs would have been already "worn out" in a sense. If the organs didn't come from a living animal, where else could they have come from?
Perhaps it is possible that they could clone organs for the Rat Things. Better yet, what if they could simply grow organs? It'd be efficient, controlled, and there would always be spare components on hand for when pre-existing rat things take injuries/damage. This still doesn't answer the issues of ethics though, which we argue about even today. If this still isn't the case, then where do these organs magically appear from?!
The next issue is getting the biological components to function with the technological ones. This is an entirely new ballgame. You can't just put a heart in a machine and expect it to beat. There has to be some sort of method of combining the mechanics of the Rat Thing with the organs it has been set up to function with. What method this is, I don't know at this point...
I suppose the Rat Thing could be considered an actual possible creation of the future, but the ethics behind its design would slow down its creation.
