@Withnail1969 Silver and Fiber Optics are better replacements for copper in some applications. Copper is still the generalist king though. It’s unlikely there’s no ability to increase supply though, esp. due to recycling and new technology.

@Withnail1969 en . wikipedia . org / wiki / Peak_copper "Copper is a fairly common element, with an estimated concentration of 50–70 ppm (0.005–0.007 percent) in Earth's crust (1 kg of copper per 15–20 tons of crustal rock).[25] A concentration of 60 ppm would multiply out to 1.66 quadrillion tonnes over the 2.77×1022 kg mass of the crust,[26] or over 90 million years' worth at the 2013 production rate of 18.3 MT per year. However, not all of it can be extracted profitably at the current level of technology and the current market value." The decline in ore quality has been ongoing since the prehistoric era, when copper could literally be obtained by walking around and picking up lumps of it. And yet, somehow, we keep getting more and more copper because we keep getting better and better at it. Again, this doesn't even include recycling or mine reclamation (reopening old mines),
