This is a fine, enlightening interview. While we can expect hyperinflation to hit eventually (or even soon), the fact that Kirby points out, that the money has already been printed / created, is truly unsettling.
That means that hyperinflation will not begin and then get out of control AFTER they hit the PRINT button, but that the powers-that-be have already lost control, and that when the SHTF, it will spread far and wide very very quickly.
And, of course, in the 1930s, Weimar Germany had to print and then distribute its hyperinflating marks. Now all they have to do is go "click."
As for bitcoin being a bubble, I recently read that .... "Bitcoin is not a bubble. It's the pin." :-)
