Chatbots’ memory functions have been the subject of online debate in recent weeks, as ChatGPT has been both lauded and lambasted for its references to users’ past conversations, with some users controversially treating it as a therapist and others experiencing mental health struggles that some are referring to as “ ChatGPT psychosis .”
