Someone told me that money is worthless because it is no longer backed by gold. I asked them why gold is any more useful and they said because it is valuable. So I ask this at the chance of being called ignorant as I know little of its actual use...what value does gold have beyond jewelry? Does it have any industrial applications (other than the ole 'anti corrosion' sillies)? Even things such as diamonds, iridium, tungsten, silver, copper, platinum, etc have some value that goes beyond looking at and calling it pretty...what use does gold serve us?
