The old, damaged arm snaps off, the new one snaps on: problem solved. Time was it would have been a trial, with doctors and operations and pain and suffering. Don’t get me started about what health care used to be like.
Now both arms are new, and both legs are still like-new, still under warranty. All of my internals are upgrades, and not cut-rate stuff either, only the top-of-the-line: when you work for GovSec you get the hookup.
But most of my head’s organic; the brain is still totally ‘factory’. It’ll be years before I have to go full-on ‘droid.
