I want to be able to put on a pair of glasses and pull up a 3D diagrammatic overlay of anything I'm trying to fix around the house or in my car, complete with tutorials. If I'm in a hardware store, I want to be able to say what it is that I want and have a path to it highlighted. I want to be able to turn a depressing walk in a crummy downtown neighbourhood into a relaxing walk in the forest. I want to be able to stroll along in that forest talking to someone as though they were walking right next to me even though they are very far away.
This stuff is, technically, not that far off. I just hope a company that respects user privacy gets there first.
