Just as the powerful capabilities of literacy effectively displaced primary orality, so too is it not only likely but inevitable (?!) that literacy will be displaced by a more powerful tool, capability or capacity.

"Post Literacy" is the phrase used to capture the possibility of rich human communication that exceeds (and hence replaces) visible language (writing and reading) as the dominant means of the understanding and exchange of ideas.

Post Literacy, as explored here, is not a decline from literacy into some new dark age but rather the beginning of a transformational capacity as yet unimagined.

And, yes, the irony of having to use visible language to explore all this is not lost on me!
