The problem is there are metals that don't fit the Band Theory of Electrical Conductivity. Tungsten and Bismuth come to mind and they are both metals.

The
plastic that conducts electricity at room temperature isn't a metal either even though the metal in it is what provides the conductivity. Your point?
I should mention given the development of polycarbonates changes the whole dynamics of cybernetics. You get things closer to the Westworld TV series then what we think of cybernetic and there was evidence that most of the events take place in 2052.
