My work in the past was on unifying computing with telecoms (i.e. performance), so the scope was "two adjacent industries". I got accustomed to seeing how people could be locked into the paradigm of either one, and unable to properly relate to the other. Only two small groups of renegades independently were working on the "unified theory of timely distributed computation", via RINA and the ∆Q algebra.
The Plan is a bit like this, but has in scope "absolutely every human endeavour and activity". It is so far beyond what most people can relate to, that there is almost no point in trying to describe it. It is often amusing to see aggressive know-it-all commentators make assertions based on the biggest "conceptual universe" they can personally relate to. All I know is that it's happening at a pay grade significantly above where I was at.
I think the smartest people understand that there is only so much knowledge that they can fully comprehend, because the information (scope of human knowledge) is constantly growing, and more than any one being can process. Maybe this is why we have turned into a planet full of specialists, instead of being like the scholars of old, who worked across the sciences and arts.
