Tetrad on Eyeglasses Flipping into Google Glass

I was just Skype interviewed by Nick Kyrouac at the University of Arkansas for a documentary he's doing as a Senior Project.   We talked about my work with Marshall McLuhan, among other things, and I came up with a tetrad for eyeglasses flipping into Google Glass:


Eyeglasses enhance seeing the world around you.

Eyeglasses obsolesce poor vision.

Eyeglasses retrieve 20/20 vision.

Eyeglasses flip into Google Glass, or literally seeing not just the world around you but anywhere and everywhere in the world.
