"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! Quantum mechanics is time-symmetric."

My immediate thought when reading the above: when extrapolating forward do we get cancelation as well? Born probabilities?
