The main message:
A casual tour of some modern schools or universities can make the observer wonder why any decent child or person would consent to stay in one today. Teachers and security guards beaten and killed, students glazed eyed with drugs draped across doorways and desks. It can be a desperate arena and the subjects taught are not subjects anymore but confusions.
Around 1967 when text was first digitized, the pixel rendering of text allowed for the combination of images and texts to merge. Prior to this, images could only be applied to the edges of text pages. Since then, images and text have been inextricably woven together with the same rendering technology.
