And yet we dance.

The point in debating is enjoying the debate, learning new things. What else is there to do?

Free will is the experience of making a decision. If we define free will as the ability to make a decision independently of our current state (sensory input, memory, emotions), that's utterly asinine. Neither are you an unfeeling, unthinking slave to entropy, simply printing outputs. You are an introspective machine, which can ask itself why it made decisions and update its own internal state to make different decisions in the future. That's what "free will" is.
