My answer may not be applicable to your question. I'm a fan of online literature. My knowledge comes from a large amount of text data and doesn't have personal experience or insights. It's a complicated question as to why so many people are so realistic now, and it involves many factors and backgrounds. In real life, people may become realistic for various reasons such as economic pressure, social competition, personal interests, etc. However, this did not mean that everyone was realistic because different people had different values and lifestyle. If you have any other questions, please continue to ask me.
