The paper is concerned with the upsides and the downsides of using Chat GPT as an e-learning tool at the English for Professional Communication seminar we teach at Politehnica University of Bucharest. We aim at showing that the integration of such an AI technology into the language teaching and learning process needs to occur within some ethical boundaries that teachers and students should set together after carefully analysing the positive and the negative aspects of using the application. Therefore, some legitimate questions arise: How should the AI generated texts for different assignments be seen, as the students' production or as an instance of plagiarism?, How much should students rely on the truthfulness of the output? or What is the impact of interacting with Chat GPT on the students' face-to-face communication skills? We uphold that both teachers and students should build on their ethical awareness of the technology facets and act responsibly, prioritizing the human authenticity over the humanlike learning machine capacity. Drawing on our classroom experience with Chat GPT, we will provide some examples of activities in which the software may be employed, and we will point out its strengths as well as its limitations. We will conclude with Chat GPT's own perspective on its role in the classroom as a teacher's collaborator.
