A correction and a question

In my new book, I use the Japanese word “otaku” to describe a special kind of obsession. Alas, my source for this was overeager and mistranslated otaku. It turns out that otaku means, “a person with an obsession.” Sort of like a geek. Forgive me please.

As for my question, my google research can’t find the answer, so maybe you can: Were there paper airplanes before the Wright Brothers? Do we know who invented them?
