There is an interesting news these days. A medical blogger posted, 'The sky is falling! After DeepSeek, the patient questioned my treatment plan, and I was so angry that I checked the guidelines again and found that they had been updated...' As of 14:00 on the 23rd, the post has received 152000 likes and nearly 30000 comments. And there is more than one similar news story. The chief physician of neurosurgery at a hospital in Beijing shared an experience of using DeepSeek to assist in the diagnosis of complex brain tumor patients and highly praised DeepSeek's performance. He believes that DeepSeek's level of handling in-depth medical problems is comparable to that of experts from provincial tertiary hospitals, and patients can trust the information it provides. At certain levels, AI has indeed demonstrated tremendous potential, even capable of replacing healthcare workers and providing professional diagnosis and treatment advice. It is also suggested that some medical workers may rely so heavily on AI that it has become a problem. Of course, it is not realistic to say that AI can replace professional doctors at this stage. The experience and examination that clinics rely on cannot be realized by AI. For example, how could AI touch a patient's body? So, although some hospitals have introduced AI, they still remain at the level of watching movies and organizing records, far from reaching the stage of 'the sky has fallen'. But AI has indeed deconstructed 'professional knowledge' at a considerable level. People used to believe that knowledge groups like healthcare workers possessed profound professional knowledge that was difficult for outsiders to understand. But AI objectively dispels its charm and restores it to its most primitive form - information. As long as enough information is mastered, professional knowledge can be constructed and professional judgments can be made. This is not just healthcare, almost all fields invaded by AI are undergoing the deconstruction of professional knowledge. For example, people suddenly realize that AI can write beautiful articles. Literary writing, which originally had a certain mystical and genius meaning and was accustomed to using mysterious colors such as "shocking wind and rain" and "crying ghosts and gods", can also be achieved by AI. This once again demonstrates that all self proclaimed professional knowledge may have a prototype in front of AI - when there is enough information mastered, professional knowledge will no longer have barriers, and all mystery will be extinguished. AI may bring about a knowledge revolution, deconstructing professional knowledge but also forcing people to redefine it. Traditional "memorization" and information acquisition no longer have advantages in the face of AI. So, what form of professional knowledge should humans possess? This may be a form of 'knowledge of information judgment'. AI can provide a series of diagnosis, treatment, and medication plans. Can humans choose the most suitable one? AI can write lengthy and beautiful articles, can humans find a valuable one? AI can integrate very comprehensive and professional information, but the value of this information may ultimately need to be defined by humans. As an interesting news in the past few days, a poetry publication has publicly published an article condemning the contributors who use AI to write and exposing some of the articles suspected of being created by AI. This may indicate that AI is not yet as intelligent, and the articles created are ultimately revealing their true capabilities; But there is another possibility that 'humanity is awakening', as people are no longer easily misled by dazzling rhetoric. Eventually, people can make valuable judgments from the stack of 'professional knowledge'. In short, the progress of AI is astonishing, and professional barriers are becoming increasingly lax; But humans must also evolve to reshape the gap in human knowledge and adapt to the future context of zero threshold professional knowledge.
