Honestly, there are some nasty problems looming on the horizon in terms of sustainability for the otaku lifestyle. Even disregarding the immediate problem of nuclear war with North Korea which threatens to nuke the birthplace of the otaku lifestyle and US, Japan is really the only country where we get this degree of high quality doujinshi, manga, anime, light novels, visual novels, and eroge. These are the roots, so to speak, of the otaku lifestyle.
The roots of the otaku lifestyle need to be spread across the globe for a sustainable future. I am personally interested in this occurring because pretty much everything that I care about entertainment-wise has some kind of influence from Japan.
In terms of problems facing such a spread that I know of, there are several.
The first is that the Japanese art quality is considerably higher than the rest of the world's. There needs to be some sort of learning "framework" transplanted from Japan to the rest of the world to bring up the rest of the world's art quality. The world's overall lack of art skill is a significant roadblock that needs to be addressed.
The second is cultural. People need to get over their absurd fear of sexuality, goddammit. 2D hentai never hurt anyone, and censoring it is retarded. Get rid of the Japan censorship law while you're at it, that thing's dumb.
The third is copyright. The current copyright rules in a lot of places is retarded; there needs to be greater protection for fan-created content to provide a monetary incentive for artists and people to get good at art, produce doujinshi, and overall raise the global art quality through the roof. DMCAing fan-content is retarded, improve the copyright laws please.
The fourth is, you guys need to actually spread this shit around the globe. Take this through Twitter, Facebook, whatever you guys are using to communicate in this day and age. TELL EVERYONE. I'm asking you guys for help because I'm a hermit who has basically no contacts and has no idea where to post this. So I decided to post this here. There needs to be a discussion about this.
tl;dr make the world's art quality better by getting a "framework" for improving art quality from Japan, tell the world to get over its stupid fear of sexuality, and improve rights for fan-created content by improving the stupid copyright laws. And TELL EVERYONE about this. Retweet, etc. There needs to be a discussion about this.
