To be honest, after learning about GPT4 and combining it with my previous experience of using ChatGPT, I feel that the subversiveness it brings may even exceed most people’s cognition, which means that this kind of technology is based on technology and knowledge. The barriers above are gradually isolating most ordinary people from the professional field, and this isolation means a huge cognitive difference. So in fact, every time there was a major technological change, I would have a kind of fear in my heart. This fear also brought a kind of "motivation" to learn. It was out of a very typical old and middle-aged "problem-solving" thinking mode. I am afraid that I will be left behind or eliminated, because I see that some people have really been left behind. And now the emergence of GPT4 tells me that maybe I may also become one of those left behind. #GPT-4
