A rather trollish and self propagandizing article... aside from what it claims... where are you getting this number of 3 years? Why not 2? Why not 4? It does not give any timeline like that.
No answer your question though... no, it won't. Not in 3, not in 10, probably not even in 30.
If there is a downfall of the US it will not be due to devaluation of currency but the realization of voters that they can use their vote to forcibly seize property from their neighbors... you know, the sort of thing that socialist systems have used for years.
