Technology of the written word

I should go and work in the library more, as it's there that interesting things pop out of my head. Here's one, thinking about literacy, society, technology and the future:

Is it our goal to widen literacy participation to the point at which 100% of the population are actively taking part in the literacy practices that will define our places in such a society? What would such a society look like and sound like? What is the technology of the written word now making possible?
