Copper, Silver, and other Metals
Easing off now, but copper price has spiked quite high.Pre 92 two/pennies are worth far more than their face value, like 2.5-3x. Silver peaked at $3.80 per gram -- https://goldtrack.io/silver. Copper hit $13.53/kg.
It's starting to sink in I think that electrifying everything requires metals, which requires mining, which requires ores high grade enough to be worth mining. Ores we uh don't have. Copper is useful enough I think that we'd still mine it if the only source cost $100/kg, but we couldn't use it liberally. Aluminum is going up too, naturally.
Use what is abundant and build to last
