I found Prof. Goodman and Rayo's discussion on the philosophy of prediction incredibly fascinating. In particular, the final section on determinism and free will piqued my interest in the intersection between science and the philosophy of free will. Prof. Goodman raised the idea that—one day—we might understand the brain at the level we understand astrophysics: that we might be able to predict human behavior with near absolute certainty, down to the next word we say. If I could add a question to this specific conversation, I would ask if pure deterministic understandings are even possible due to the inherent randomness of the physical world? In particular, I would ask about quantum indeterminacy and its implications for determinism.
