No one is going to buy glasses that only show ads, that's obvious. They'll start out with something useful like glasses that recognize people and show you their public Facebook profile info. Or you look at things and it will identify what it's made of. Or show you a recipe of a dish you see in the restaurant. Later on, when everyone's hooked they'll start showing these "relevant ads" when you look at things. Slowly at first but over time it will become a torrent. I'm going to torch these things publicly in the street if this ever becomes a reality.
