This is true.
Well by fix, it could be like DJspiderize said could be a reversal of emp it would be difficult but worth it,
and yes i think it would be like tron i guess or kinda like how anti matter moves.
Plus it could seek out broken parts if you erased part of pscn nscn and such it would go through the metal and slowly begin to repair it from inside or outside.
ps sorry i was away from forums so couldnt respond ok.
It would be way too hard to code, I think.
