Ha! I love it. That notion -- that the future becomes the past -- reminds me of the Ted Chiang story Story of Your Life.

I'm open to probablism. Right now I'm trying on determinism and seeing if it fits. So far so good; I've not heard a single argument that convincingly refutes determinism, mostly just kneejerk reactions caused by the persuasion of the illusion of free will and the perceived implications of letting it go. However, your argument seems like it's giving determinism a run for it's money... but I might not have fully grasped it.

You're saying that the future becoming the past is incompatible with cause and effect?

Perhaps I should re-read...
