NY Times

Perhaps the best way to predict how society will react to so-called wearable computing devices is to read the Dr. Seuss children’s story “The Butter Battle Book .”
The book, which was published in 1984, is about two cultures at odds. On one side are the Zooks, who eat their bread with the buttered side down. In opposition are the Yooks, who eat their bread with the buttered side up. As the story progresses, their different views lead to an arms race and potentially an all-out war.
Well, the Zooks and the Yooks may have nothing on wearable computing fans, who are starting to sport devices that can record everything going on around them with a wink or subtle click, and the people who promise to confront violently anyone wearing one of these devices.
I’ve experienced both sides of this debate with Google’s Internet-connected glasses, Google Glass. Last year, after Google unveiled its wearable computer, I had a brief opportunity to test it and was awe-struck by the potential of this technology.
