Neural networks will degenerate in the process of learning from their own hallucinations, and humans will degenerate in the process of applying the degenerated neural networks. This process is called "neural network collapse". https://arxiv.org/abs/2305.17493v2 It can only be countered by a collective neural network of all the minds of humanity. For mutual validation and self-improvement of LLM and humans, we need the ability to match the knowledge of artificial intelligence with collective intelligence. Only the CyberPravda project is the practical solution to avoid the collapse of large language models.
