Google clearly didn't anticipate the class and cultural conflicts that define the Glasshole.
The geek who thinks he is riding The Wave of The Future and pulling the rest of the world along with him, like it or not, is a very big part of the problem.
1 The frame should be easily folded and pocketed like any ordinary pair of glasses.
I spent the strangest of Christmases lit by the glow of the cell phone and tablet --- --- an obsession with the gadget so strong it destroyed any sense of a dinner with family and friends.
2 The geek will want a next-generation Glass with HD displays and cameras, front and rear facing, night vision, more sensitive microphones, better battery life, gigabytes of storage, unrestricted apps, including facial recognition with Internet connectivity, etc., etc., etc.
None of that is going to happen in the consumer market until the issues of privacy and respect for others are resolved first --- and hiding behind the geek's favorite legalisms ---"public space!"--- and memes like "Privacy is dead!" will bury Glass six feet under with no hope of resurrection.
The camera must remain visible. There can be no doubt when it is in use.
I would be very strongly tempted to insist on a warning when the audio and video feed is being streamed to the net or being interpreted --- augmented --- by internal or external apps.
3 The geek will predictably cry "Censorship!" Political correctness. But allowing AO apps into the Glass store would be disastrous.
Who wants to live in a society populated by wandering cyborgs staring vacantly into space.
There is no straight line from the introduction of the cellular telephone of the eighties to the placement of an all-knowing chip in our heads in the 22nd century, With each technological breakthrough we consider [what has been lost and what has been gained] Then we react.
Google Glass is the creepy innovation we didn't want.
