Ron Paul has predicted it pretty consistently for about ~25 years at least and as far as I'm aware the mises institute has agreed with him all of that time. He is probably the most high profile Austrian adherent that I know of and mises the most high profile think tank dedicated to it.
I'd be interested in hearing about all of these academic Austrians who have argued that they are both to be full of shit.
Sure, but first, who are all of these Austrian economists who think Ron Paul, the most famous proponent of their brand of economics, is full of shit and when did they call him out on it?
Ron Paul is a politician, and the Mises Institute (which is not a think tank and not the most high profile Austrian/Austrian-inclusive organization) has largely disagreed, other than Gary North and Doug French, who are both about as low profile and unserious as you can get.
Also, Ron Paul usually doesn't predict hyperinflation, though I would agree that he's very hyperbolic.
