I have not updated explanatory pages of comments but the 2nd page (graphical) of the document below, a published Google document, has been updated. In particular a track of things trying to be cognizant of Harris theory (how human society really works, which isn't pretty) has been added. It is a lot to look at on one page. However it seemed as if having a summary timeline, however imperfect or unblessed, would be a good thing to be able to point to as a trial balloon or proof of seriousness in thinking things through in a pragmatic way.
I have extremely thick skin, so feel free to blast away with critiques if the spirit moves you.
