Some scholars have recently stated that: “We believe that AI ethics will develop such that it will become clear that the field is inherently interdisciplinary” (Kazim, E., & Koshiyama, A.S., 2021). Others have echoed these sentiments in various ways. My aim is to reflect upon this vision of interdisciplinarity, and ask: should AI ethics become interdisciplinary, will it become so given the history of similar efforts in other tech disciplines, and what tensions or inherent characteristics of AI as a branch of technology development and of ethics as a branch of philosophy, might prevent interdisciplinarity? I will concentrate primarily on the potential interdisciplinary relation between AI development and ethics as philosophy, but stray somewhat into other disciplines also. I will conclude by offering some reflections on what it may take to bring ethics into interdisciplinary engagement with tech development, e.g. the philosopher will have to learn tech knowledge proportionately to the tech developer learning ethical knowledge.
