The future will still be a surprise when I get there and all it is is the present getting data from the past.
Is the future "real" in that example? Hard to say ... by taking positive action we certainly make it real. One supposes it's a reasonable analogy to the "observer" aspect of quantum theory.... And in that sense I suppose the future in our macro world, is similar to what we can observe in the quantum world. I don't think there's serious doubt that the quantum world exists in some objective sense ... and I think "the future" has many of the same features.
As religious folks, of course, we accept that the "God's eye view" of reality most likely eliminates the distinction between present and past, at least in the way we perceive them.
