Free will strikes me as either impossible (uncaused causes) or arising from quantum randomness, which isn’t what most people mean by free will. And it’s an illusion that’s here to stay as part of our day to day mental activities, unless you consume mind altering drugs or suffer from depersonalization disorder.
It’s far from settled inasmuch as it’s impossible to “settle” a debate where one of the positions is fundamentally incoherent. The debate on whether we have free will is isomorphic to the debate on whether we have Fweem. Nobody knows what fweem is, and nobody can describe any difference between a world in which fweem exists and a world in which fweem does not exist. And yet many people are highly opinionated about fweem even though their attempts to describe it are invariably self-contradictory.
What difference does it make? If the present-existence-of-the-future is something we cannot even in principle perceive from our present-present existence, than from our POV we might as well be living in a free-will universe.
