The difficulty I have in understanding and interpreting this is that everything which is contemporary to "us" and comparable in scale to "us" seems to have the same basic coupling to the rest of the world. that goes for a singlecell amoeba and for me and for the solar system. We all depend on (what is needed for us to do what we do) the same macroscopic variables and processes. We, collectively, are the observer. I cannot imagine an alternative collection of entities. So I cannot imagine a different overall direction of time.
