Uh... as someone trying to engineer this stuff, you should know that it can't be hacked if it's just hardwired to the main controls. (ie. your brain tells your arms what to do, and nothing more.)
Not to mention, the phone in my arm would connect to wireless, NOT my brain or prosthetics. There would be a mic somewhere in my throat or something and a built-in speaker in my ear. In any case, my arm would likely still be my arm, just with the added bioelectronics, so there's nothing to hack there.
If we could hardwire, that would be brilliant. I'm still looking at if I can get an internship or something to know more about the exact functions.
As I understand it so far it's never a 1:1 relationship, it's many to many. Whole families of cells in the brain for a single "muscle", and not all of them spike at the same time nor with the same amount.
Now you either need a way of processing that or a way to compensate.
With a fully organic arm just boosted THAT wouldn't be a problem, but crushing your bone to splinters or obliterating your tissue might be (the human body wasn't designed for extreme forces).
As for purely mechanicsl - yes in general if you keep the systems separate there shouldn't be any interference, I'm just saying about if you had a direct link in to the arm system (for updating it or centralising control or something, cheaper if you have one strong chip I guess).
What I'm still more worried about though is actually POWERING the arm. I've not heard anything on that topic. Especially if we're going for futuristically-bionic-strong, it's going to need some workhorse of a motor and a way to power it :/
Another thing I've really wanted to consider is the feedback for the touch (and possibly pain due to the stress on the motor - you don't want to break it) systems.
Again most of this stuff if you have a theory, great. BUT. How do you implement them? An arm needs to be able to move, so maybe have fixed transmission lines within the arms, then flexy cables at joints (a vulnerability)?
It would still probably be more difficult to attack that than the human portion of the body, but I'm not saying it's impossible. I guess I'm just thinking a bit too far ahead and reading too much in to it.
Sorry if I went on a bit of a mad-scientist rant there. Sometimes I tell myself that I like this stuff a little too much.
