In the history of fiat or government-produced paper money, no fiat money in history has ever survived, all are now museum pieces.
The reason is that fiat money is produced (without the discipline of gold) in any quantities a government desires.
When an economy slows (as now) or when a nation goes to war (which is always wildly expensive, as now) the temptation to print the needed "wealth" becomes overwhelming.
Eventually, the world distrusts man-made "money." In the end, each new issue of fiat money dies. The fate of the US dollar will be no different. Which is the real reason why we hold gold for the long-term.

I have seen many people debate whether gold is a bet on inflation or deflation. As I see it, it is neither. Gold does well when monetary and fiscal policies are poor and does poorly when they appear sensible. Gold did very well during the Great Depression when FDR debased the currency. It did well again in the money printing 1970s, but collapsed in response to Paul Volcker's austerity. It ultimately made a bottom around 2001 when the excitement about our future budget surpluses peaked.
Prospectively, gold should do fine unless our leaders implement much greater fiscal and monetary restraint than appears likely. Of course, gold should do very well if there is a sovereign debt default or currency crisis.
