I'm going to be honest: I lost interest halfway through the introduction and scrolled through since Stephen Wolfram is notorious for this kind of approach. The fact that the term "grammar" occurs exactly zero times in the entire articles makes me feel like he is just reinventing the wheel without regard for prior work and is simply phrasing (some) physics in terms of generative type-0 grammars and then playing around with that notion without putting forward any actionable hypotheses.

So a question for those of you who did read it properly - am I missing something with that assessment that would make this worth the ~1 hour to really read it?
