Currently, there are three methods for creating circuits using graphine. Smashing, spraying and now vapor grown. If the graphine is perfect and I mean, every carbon atom utilizing its four bonds to connect to another carbon atom, we get pretty close to super conductor. These sheets per the nature article are at ~280Ohms resistance.
Once we have the ability to reliably "print" sheets with circuits, we come to the point of refining our circuits for each application and we can then get away from "central processing" for further imporovements.
We have a long way to go with this technology but the future looks bright.
