IF AI HAVE NO SOUL, WHAT GOES INTO MY SONGS?
Vivy takes the stage at the Zodiac Signs Festival, site of the next Singularity Point. There she meets Ophelia, an AI who committed suicide in the original history, and must confront the idea of whether AIs have souls. During their search for the truth to prevent the incident, Vivy comes face-to-face with a human she knows…a human who shouldn’t exist!
So, does an AI taking her own life prove she has a soul, or does it point to something else entirely?
