The reason here is not complicated. On the one hand, so-called new ideas can attract people's attention and have the opportunity to become so-called academic achievements, from which those who create achievements can benefit. This gives the so-called experts and scholars the motivation to constantly put forward so-called new ideas and discoveries. Moreover, the more distinctive and striking these so-called new ideas and discoveries are, the most distinctive is the viewpoint of completely subverting the conclusion. On the other hand, our social environment is indeed much more relaxed, and people dare to put forward so-called new ideas. If it is in an era when everyone is guilty and everyone is silent, who dares to do so? However, it should be admitted that these so-called new ideas are not groundless, and many of them still need to be copied, and they cannot be simply regarded as a belief.
