“Idea” means figure or form in Greek. Alter3 and Alter4, which represent the world of ideas and phenomena as defined by Plato, are installed facing each other on the stage, and their faces and expressions are projected onto the screen. Alter3’s every spoken word is converted into movement by GPT, with everything down to its movements controlled, while Alter4’s responses to the volume, pitch, and density of the music played by Shibuya and the oscillators attached to its body are modulated to generate periodic movements. The entire script is generated by GPT, which has also learned all of Plato’s works and Karl Popper’s criticisms of Plato. How are these things possible, and what kind of conclusions did they reach?
