Father of wearable computing +Steve Mann, who briefly wrote for me when I was at About.com, says he was assaulted by employees in a Paris McDonald's, because they didn't like him wearing his gear.

It's unclear why they were offended by his headset, but perhaps the fact that it records what he sees was a point of contention. 

What will society be like when everyone is wearing AR glasses 24/7 so everything you say and do is on film? Will people still go to the movies? Will they attend confidential meetings? Or will secrets themselves become obsolete?
