When "Lo and Behold," Herzog's documentary about the Internet, came out in 2016, he did a screening at Stanford. Afterwards some undergrad crypto bro asked him for his opinion about Bitcoin. Herzog replied that he was anti-Bitcoin because he needs cash - untraceable, hard cash - to keep existing, as sometimes when making his films he needs to do crimes such as paying bribes to local officials. The entire auditorium went silent. Still the most effective way to shut up a crypto bro I've ever seen
