Electric cables at very easy to make in metal, in fact I'd wager 90%+ at least are made of copper in the whole world.

Electric cables are made from insulation (plastic) and wires (metal). Wires use metal, insulation typically does not, so it's NOT easy to make a whole cable out of metal.

Do you mean silicon or silicone? The former isn't a very good candidate for flexible cable insulation. The later is a form of plastic.

If I say humans are made of polyester you wouldn't correct me? You usually meet them wearing insulation too.
