Could a generative AI chatbot have a real relationship with a person? Allison Pugh, a sociologist, argues no: “there is no human relationship when one half of the encounter is a machine,” she writes. In her argument, Pugh describes how care-focused generative AI platforms–such as the ones being used in education, medical, and therapy settings–damage human relationships by making people feel both invisible and disconnected from each other.

The other side is not evil: Kurt Gray on how fear drives political divides
