The whole "waves of differentiation" idea is quite an interesting one and certainly seems to me to be an almost physical description of philosophical concepts like free will and determinism. Perhaps these waves themselves interfering are what gives rise to what we consider consciousness, since what we experience subjectively is changing at every moment. Maybe the only reason we are able to "think" at all and remain "coherent" and "self-subjective" in our own brains is that these waves create images of the past on all their neighboring matter that have a continuous time-evolution. There certainly (to my mind at least) seems to be an element of randomness to thought that feels quicker and less coherent than could be easily explained even by a large-ish number of neurons with a comparable but larger number of interconnections.

I dunno, it seems a little overly-philosophical but surely there are meaningful connections to be made between physical reality and the transience of subjective experience.
