History has recorded hundreds of currencies that now are worth nothing, the only difference with the US dollar its that is going to be a worldwide event
No it probably won't (I mean, it might result from a worldwide event, but it won't likely cause one.)
Most likely, other than being caused by a global catastrophe, is that the center of global finance gradually shifts elsewhere long before the US dollar becomes worthless, and if that ever happens, barely anyone (outside of the US, especially) notices much.
