A few weeks after the launch of the AI chatbot ChatGPT, Darren Hick, a philosophy professor at Furman University, said he caught a student turning in an AI-generated essay."All of a sudden you have someone who does not demonstrate the ability to think or write at that level, writing something that follows all the requirements perfectly with sophisticated grammar and complicated thoughts that are directly related to the prompt for the essay," he said.Christopher Bartel, a professor of philosophy at Appalachian State University, said that while the grammar in AI-generated essays is almost perfect, the substance tends to lack detail."They give a statistical analysis of how likely the text is to be AI-generated, so that leaves us in a difficult position if our policies are designed so that we have to have definitive and demonstrable proof that the essay is a fake," he said."The confession was important because everything else looks like circumstantial evidence," he said."
