This letter to the editors takes a deeper look at the validity and ethics of authorship of a recently published article in Nurse Education in Practice in which authorship was shared with a chatbox software program, ChatGPT (https://doi.org/10.1016/j.nepr.2022.103537). In particular, a closer assessment is made of the authorship of that article from the established principles of authorship as delineated by the ICMJE.
