>a great way to get out of the old determinism v. free will debate
How exactly?
1. Chaotic processes are deterministic. What's special about them is the extreme difficulty of making accurate predictions because of sensitivity or complexity.
2. Even random processes aren't free in any reasonable sense of the word. A random process can't 'choose'.
3. Free will is impossible. To truly choose is impossible. All processes are combinations of deterministic - in theory predictable - and random - unpredictable even in theory - processes. Neither is free and there is no room for anything besides those concepts.
Free will is bullshit. It doesn't even not-exist. 'Free' in this context doesn't even refer to anything coherent that could exist or not-exist. Free will is an impossible concept.
