It will be interesting to watch silver prices in the long term (20 years),as it's supply will be getting lower,while some important industrial applications will unlikely to ne replaced quickly enough.
I think Silver is the straw that will break the camels back, it’s hard to know if it will be in 1 or 50 years but it’s fungible and affordable while also having increased industrial usage. At this point it is almost at parity for industrial consumption as it was in the 90s when silver was used to develop analog film. It’s certainly true that topological insulators may replace silver in many electron transfer applications. That being said medical uses due to the way it kills micro organisms through sulfur attraction, and it’s thermal properties, will possibly continue to expand industrial consumption.
