Silver is a much better conductor for electricity. In fact it’s the best. Great bar bet factoid.
Gold has all kinds of practical uses but not at 1500 bucks, that’s the problem. Silver is interesting because it has unique properties that don’t allow for substitution with less costly materials. Aerospace applications, plastics production, water purification, certain burn creams, etc.
Silver tarnishes while Gold (the 2nd best conductor) is forever, so any computer chip or such made with silver wouldn't last long, which is why Gold is preferred.
