Wolfram's ability to create interesting visualizations is fantastic. But I seem to feel underwhelmed at the significance of his discovery.
In short, he says that the Second Law of Thermodynamics is a consequence of the fact that we as observers are computationally bounded and cannot perceive all the details in the the lower-level, computationally irreducible physical systems around us.
Yet this does not seem enormously different, or perhaps not different at all, than the standard account in statistical mechanics in which the observer is considered to be coarse-graining over the fine details of the system which are too complex to track.
What is new in Wolfram's approach other than using computation-related labels to describe the situation? For example, his 'computationally bounded' observer is just the standard 'coarse-graining', right?
