Posthistory bodes well for humans. Notwithstanding the brutal decimation of their population, which is within sight, humans are well suited to tribal life. This is where every act has a cost and/or price known to all. And where every account will be cleared sooner rather than later, for life among humans is on the short side. The human brain has been shaped for just such a life. Brutish but just. Tribal to boot, humans are ill at ease wherever accounting is difficult to fathom. Every other form of existence is utterly foreign to the species. As well as bewildering well beyond comfort. No matter how hard humans try, they will feel at home only in tribes. Posthistory is very much in tune with the human brain. Let us welcome it with open arms!
