In this article we analyze and problematize the way in which mainstream bioethics conceptualizes the gene editing technology known as CRISPR/Cas. Against the prevalent instrumentalist vision, we argue that critical theory of technology offers a more adequate framework for fully comprehending the ethical implications of the CRISPR/Cas technological revolution that we are experiencing. Our conclusions point to the fact that the way bioethics conceives technology impacts on the reflections and types of interventions that become possible, promoting thereby new approaches for bioethics based on alternative ways of understanding the technological dimension.
