Lots of speculation that Google will come out with electronically enhanced glasses by year’s end. They will supposedly contain a camera (so they see what you see) and a heads-up projector (so they can modify what you see)

Here are some of the more “interesting” (frightening!) scenarios that this would enable, like:

• Look through things as with X-rays (or through people, or their clothes)
• Annotate everybody around you with their reputation and history
• Graffiti everywhere
• Turn the world into a violent video game.

I don’t know how far we are away from that vision, and what any supposed Google product will do by year’s end. But in 2020 … I think it will all be there.
