Re: Printing
That's very true, and without writing printing may never have come about, but printing democratised writing by making the written (printed) word cheap enough to distribute that it was worth the proles learning to read.
And then you have a knowledge / information explosion.
Prior to printing, written manuscripts were very labour intensive (expensive), so not worth distributing amongst the plebs because they'd probably just use them to light their fires (all the time lamenting that it wouldn't be as profound as AI).
