"We must not forget that it only took the Weimar Republic 4 years to hyper-inflate their currency into oblivion...and that was before the electronic printing press, where billions can be injected by a few simple key strokes."
Agreed. On the other hand, the Weimar Republic did not have the entire world to distribute its currency to, like the US has.
Which makes me realize, that if the world were to panic and try to get out of the widely distributed dollar very fast, also the dollar may indeed collapse very fast. This could probably only happen, if the US were the only one to print money, but as we know the EU, Japan and even China are doing the same.
