Oh, I forgot to highlight the importance of such an idea (observed in an experiment last year:
Onur Holsten & Paul Kwiat).
If Time Symmetry is real, then there is no probability in Quantum Mechanics and no uncertainty either as particle event outcomes are deliberately matched to suit the future reality not yet created. For simplicity, I called it a Floating Point Future (FPF), and the overall process the Floating Point Future Processing (FPFP); it uses metric values through the Calabi-Yau to do it.
