Perhaps not trivial in chip interconnects, but it's fairly abundant and a rather workable material in general (hence the bronze age). Faraday probably wouldn't

Perhaps not trivial in chip interconnects, but it's fairly abundant and a rather workable material in general (hence the bronze age). Faraday probably wouldn't have gotten very far if copper was a gas at room temperature or only occured in trace amounts and there were no other ductile, solid conductive materials on Earth.
