In his white paper titled "Why do we do astrophysics? ", author David W. Hogg delves into the implications of large language models (LLMs) gaining the ability to design, execute, write up, and referee scientific projects in the field of astrophysics. He presents a set of agreed-upon facts about what astrophysics is or should be, touching on aspects such as novelty, people-centrism, trust, and clinical value within the profession. Hogg explores the various benefits that astrophysics brings to individuals, science, universities, and society at large including considerations of love, weaponry and personal development. He strongly argues against both extreme approaches and emphasizes the importance of developing moderate policies in navigating the integration of LLMs in astrophysical research. This thought-provoking paper raises critical questions about how advancements in technology may shape the future of astrophysics.

Abstract: At time of writing, large language models (LLMs) are beginning to obtain the ability to design, execute, write up, and referee scientific projects on the data-science side of astrophysics. What implications does this have for our profession? In this white paper, I list - and argue for - a set of facts or "points of agreement" about what astrophysics is, or should be; these include considerations of novelty, people-centrism, trust, and (the lack of) clinical value. I then list and discuss every possible benefit that astrophysics can be seen as bringing to us, and to science, and to universities, and to the world; these include considerations of love, weaponry, and personal (and personnel) development. I conclude with a discussion of two possible (extreme and bad) policy recommendations related to the use of LLMs in astrophysics, dubbed "let-them-cook" and "ban-and-punish." I argue strongly against both of these; it is not going to be easy to develop or adopt good moderate policies.
