In recent years, the use of AI to write papers has become increasingly popular. It is very common, and many universities have developed tools to check for AI-generated content. Now, in addition to the original requirement for plagiarism checks, there is also a requirement for AI detection in graduation theses. Previously, when I was writing my thesis, I also used AI, but I found that when using AI to search for relevant literature, some of the literature it presented did not actually exist; it was fabricated. I was thinking about AI.
