Good job indeed. Good job at writing the prequel to the new "Repo Man" movie.
Having just seen it, I made the same connection - but I came to a different conclusion. It just makes the movie look more stupid. I mean it already looked pretty poor. The story might have worked if it was made 30-40 years ago, but with medical science where it is - the thing looks pretty anachronistic.
While I was watching it, a number of things jumped out at me as silly. One of them was the cybernetic nature of all the implants - and therefore their ability to be "repo'd" at all. "Replacement organs aren't going to be mechanical" I thought to myself, and mentioned to my friend, "they are going to be biological and derived from your own cells".
This achievement pretty much bears that out. There would be no use in taking back what is essentially a "custom" organ - like this kid's trachea. It is of no use to anyone else because it uses his cells. The best you could hope for in that sort of vein (no pun intended..) would be to take it out, restrip it, and reseed it with someone else's cells. Or transplant it the traditional way (say, if it was a kidney).
But I am betting artificial scaffolds will be developed in short order (they are already working on them), and they'll be able to just fabricate organs from scratch. This will be cheaper and easier than donors anyway. People waiting for transplants are very expensive to the system - cooking one up and getting them out of the hospital fast will appeal to even the most evil CEO.
I think the future will be a bit brighter than the movie portrayed - at least in terms of artificial human organs.
