Here's a short story on a similar subject, the ethics of a brain transplant. Won a Hugo in 1973. http://docs7.chomikuj.pl/1852561988,PL,0,0,Frederik-Pohl---T... Ignore the first 2 paragraphs. Its the end of an introduction by Issac Asimov from an anthology of Hugo winners.

Some people appear to be trying to use rational arguments to persuade me that I shouldn't feel creeped out.

You'll fail. Rational arguments reach an entirely different part of my brain.

I don't see why it should be an issue in a world where we already do transplants. It is just more of the same, an iteration, albeit a very impressive advance.

Are you creeped out by the idea of an arm transplant?
