This is a very reasonable conclusion, however it raises an equally reasonable question. How does fiction happen?
Let me explain: Free Will is the manifestation that sets appart things that will exist and those that won't, in general, we think in the basis of hypothetical assumptions to understand the universe because we cannot fully experience anything. So Free Will is producing hypothetical situations, and those fictions are implied through each choice but they never actually exist. Its a machine that makes lies. But some lies could've happened, while in deterministic models there is just one thing that happens and contains the rest, what do we do of that things that were potentially possible in opposite to those that could've never happened anyways?
I think there is something inherently disappointing about that, as if our mind placed some sympathy towards missed opportunities.
