And some day in the future, gold will be absolutely worthless.....
Ezekiel 7:19 They shall cast their silver in the streets, and their gold shall be removed: their silver and their gold shall not be able to deliver them in the day of the wrath of the Lord: they shall not satisfy their souls, neither fill their bowels: because it is the stumblingblock of their iniquity.
Its possible to make real gold out of another metal, but it requires a nuclear reaction and is much more expensive than just digging up gold.
This is just a badly written article. This concerns treating copper so it behaves like gold in electronics, thereby making them cheaper.
