To me this is not really a matter of whether or not we have libertarian free will. In fact I think we don’t and need not posit it to explain anything. My point is perhaps more that when we talk about “determinism” it’s often mixed up with ideas about a clock-work universe that flows forward in a particular way that we can calculate in advance, but the computation is so complex that the only way to do it is to actually let time advance so the computation plays out in the real world, and thus although the present and future may be linked to the past it can’t be known as well as we can possibly know it until we get there.
