People sometimes quote “Anime was a mistake”, and attribute that quote to Hayao Miyazaki. Now, I’m fairly sure itas a joke, but it can be hard to tell with some people.
Assuming it isn’t a joke, there are a few problems with that:
Hayao Miyazaki definitely invent anime, so he can’t be to blame for it.
Also, if that quote isn’t a troll quote, is the point that he thinks it was a mistake to get into producing anime movies? Or did he think anime was someone else’s mistake to begin with? Do people genuinely assume he invented it? There are dummies and trolls alike around the web, after all.
