This is neat. I think there's a way around it tho. What if you can division the futures high entropy states into k, lower entropy states, and subdivide those, and so on. Substructure. Information about some of those substates can flow back from the future and be detected by observers in the present, IMO. It's not easy, but it's possible and it happens. There's still signal. The bandwidth is not nearly as much as the flow from past to present, but it's still more than any single observer can possibly hope to ingest, so some details of the future can be reconstructed by some observers in the now.
