I think it's reasonable for beardozer to wonder if copper will be replaced.
Graphene is a far superior material for conducting electricity. You need a lot less of it to do a lot more, so weight reduction too.
However... manufacturing processes, supply chains, suppliers, clients, electrical interfaces, qualified technicians, inter-operable components etc etc etc will take many years to establish. Graphene is also difficult to manufacture and very expensive, so it's probably decades before it's used in preference to copper, if ever.
Currently, there's very little copper in warehouses. Demand is going to be global (not just China). Exploration/discovery to production takes many years. Rambler produce. +beardozer, I think you should hang around for a year or two.
