What I really hate about these sorts of stories and attending discussions is that we all pretend we know what "free will" is, when no one has ever come up with satisfying definition (just look at the Wikipedia page). My humble opinion: all hand-wringing about lack of free will should be put on hold until we can answer the following question: In what way will an entity that has free will behave differently than both a fully deterministic entity and an entity that is deterministic excepting occasional random events? I have yet to see either an answer to that question, or a definition of free will that leads to one. Until then, I consider all speculation and meditation on the "revelation" that we have none to be a tale full of sound and fury, signifying nothing.
