I wonder at what point these arms are going to get better. I suspect it'd be a lot easier to train a prosthetic arm when there is still a physical arm to be attached. Doing this before a replacement should really cut down on the 'rehabilitation time'. Perhaps, in the scenario, it is better to just leave to current arm attached and give a prospective cyborg a third arm rather than replacing the current arm.
