Harvard University is undergoing an AI revolution, with AI permeating every aspect of learning, research, and daily life, from students to professors. 87.5% of surveyed Harvard students use generative AI, with ChatGPT being particularly popular, as students utilize AI to assist in studying, including answering questions, writing papers, programming, and even reducing interaction time with teachers. However, the proliferation of AI has also raised concerns about fairness, career prospects, and the future status of humanity. In response to these challenges, Harvard is taking measures such as providing free access to AI, establishing usage guidelines, and offering courses.
