In fact, I have been thinking about this problem since I was very young. Recently, it is also popular to check the literature first when encountering problems, because most of the problems we encounter now are experienced by predecessors or have relevant information on the Internet. But the reality is that time will change and people will die. Nowadays, people receive a lot of new information every day, and fewer and fewer people can settle down to study similar events in history, and it is even more difficult to take the initiative to study before the problem breaks out. People will generally say why SARS was infected by eating game 17 years ago, and now it is caused by eating game again. It is likely that the people who bought and sold wild animals were still young or far away from the key outbreak areas, so although there was a similar history, many people have forgotten the pain of that year. When I was a child, I used to think that with such a long history, knowledge could never be learned. Why not invent something like a chip, which can be put into people's brains? This chip is not free, but needs money, and it is based on disciplines. If you have money, you can buy more knowledge about different subjects, which can be called up in your brain at any time, but how to use knowledge depends on your intelligence level. I think that although the current search engine is very developed, it is still more troublesome to search for information. For example, I want to check the origin of "history will not progress, history will only repeat itself", and I checked Baidu and Google. These search operations also take time.
The recent debt crisis also mentioned that politicians don't know what to do when they encounter an economic crisis. Yes, they know that there is the same history to learn from, but few people study it, or the words of the studied experts are too true for everyone to listen to or believe.
