The abos are not so innocent as the liberals want to portray them after all.
Here's the thing: the upside of inventing a writing system is world domination; the downside is finally having to admit in public that you are a real ass (and always have been).
In the above, "you" is a set of nesting dolls, innermost being the fifty-year-old white male technocrats of western European origin who treat Wikipedia as their private, personal playgrounds (thence to aging white European males, white European males, white males, whites altogether, etc.)
Here's the second thing: after a society invents writing, soon the society has written myths (with serious legacy entrenchment) that innocence preceded the current sad state of affairs (how-far-I-have-fallen porn, not that the larger consequences can't be remedied by kneeling under the right cumulus cloud for a thoroughly abject sixty seconds).
Society will re-invent writing over and over again (movable type, Movable Type) before the reversal of true illumination makes the least headway: that the human asshole apogee was attained circa the advent of the original edged weapon.
As far as the abos go, they all need to repeat to themselves "there but for the grace of God go I", unless they think their ancestors truly enlightened enough to not have had even the most remote possibility of inventing any form of written record, whatsoever (best if you're not much past the wreathie leafy loin cloth, because any loose thread threatens to quipu a long record, and then immediately you're on the outie asshole train along with every other post-prehistoric posse of mugs, pugs, and thugs).
