@Eliezer: You say If you took one world and extrapolated backward, you’d get many pasts. If you take the many worlds and extrapolate backward, all but one of the resulting pasts will cancel out!
If this is true, then why do we calculate forward based only on our current configuration? If we took all the many worlds in our possible pasts and extrapolated forward, would they cancel out all but a single future?
