I think this question is not absolute. We can't say whether it is good or bad. It has two aspects. Otaku culture refers to staying at home and focusing on your own things, such as surfing the Internet and playing games.
But I think with the development of economy and the strengthening of internet technology, we can know all kinds of things happening outside without going out, so many people are increasingly reluctant to go out and choose to stay at home.
Especially for teenagers, many primary and middle school students often stay at home to play games, computers and mobile phones during winter and summer vacations or weekends. They won't go on holiday. Parents let them go out to play, and they don't want to go out. They prefer to stay at home and play games.
That's my brother. Before, when he didn't have a mobile phone to play, he often went out to play football and various games with his classmates. But with the mobile phone and the Internet, he goes out less and less.
Sometimes he doesn't even want to go shopping. Therefore, otaku culture does have many bad effects on young people who have no ability to distinguish right from wrong.
Teenagers are not psychologically mature as adults. There are many good things and many bad things on the Internet. They don't know what is good and what is bad. Therefore, parents should teach their children to surf the Internet in a civilized way.
Parents should also strictly control their children's time online and playing games, and don't let their children indulge in the internet and have no intention to study.
It is said that the network is a double-edged sword, which brings us a lot of convenience, but also brings us many adverse effects.
However, the development of otaku culture has also produced many new jobs and provided more job opportunities for many people. Some people who are engaged in creativity and e-commerce often work from home.
