The world is not going to go back to using gold as a currency. As jakethesnake points out. There is a limit to how much gold there is. And if they find new ways to mine more it will affect the price of the resource.

There is more debt in the world than there are assets, there is more services and commodity's to buy in the world than there is gold.

Countries and even regions will continue to have fiat currency's. If we don't then the fianancial fakery of the world will implode. There is more debt than there is money. Every time a car is purchased more debt than wealth is created. It will come to an end one day. But its those guys that fill up vans with fertilizer and park them in front of government buildings that are propagating fear. And this discussion is not very far from that level.

Anyway I can wax eloquently about all of this because its been said that this can all affect the price of my shares in SI. Just not today by the look of it and not off topic.

Shall we continue?
