I believe the future can easily affect the past as much as the
   past the future. The final form giving clues for how it *might*
   become, like echos.

   But as in fate or destiny in a fixed sense, or "no free-will" as
   in a Science sense? No.

   More like possible future selves calling backwards in time.

   Otherwise, it's series of choices based on constraints provided.

   Mind you, there is a _lot_ of freedom within the constraints.

   [example constraint: gravity. Having eyes. Using language. All
   constraints. But we work well within them]
