It all hinges on the petrodollar, which is far far more unpredictable than the basic math of currency inflation. We would already see a DOA dollar if not for their ability to export monetary inflation overseas and put it into the world reserve where the bubble potential is an order of magnitude larger.
If the petrodollar/world reserve currency status of the US Dollar fails, or there is some dramatic move away from it, the US Dollar will have at most 3 months (after that 'event') before a severe monetary crisis here in the US. (I usually say 6 weeks to 3 months). If the petrodollar/world reserve currency status of the US Dollar does not fail, then math is still math and even exporting the bubble it will still reach critical mass within 5 to 10 years. I'm not the only one who can do the math, so I expect that the rest of the world will not wait 5-10 years to unhook...but if they DO, and if the petrodollar DOES keep surviving indefinitely, then the collapse of the US Dollar in 5-10 years will take down the entire planet...or at least all those countries still trading primarily in dollars.
So yeah, there is an unpredictable human element to this: the endurance or failure of the petrodollar. I expected something like the India/China move around May instead of July. I expected by August, that the first country would start migrating all their international transactions from the dollar to the new currency (in this case the Renminbi) and that a second major country would join them. That may take until September/October now. It remains technically possible that the world will keep hanging on to the dollar anyway, but I consider that unlikely, since right now THEY are getting hurt by the Fed's monetary inflation even more than we are, and I don't think that the rest of the world is going to sit idle while the US slowly feeds them arsenic.
