Who was that man wearing super high-tech, $1,500 smart glasses on the New York City subway?
According to a tweet by a guy who got a picture of the mystery glasses-wearer, it was none other than Google co-founder Sergey Brin, wearing a prototype of one of the most highly anticipated new tech products -- Google Glass.
Noah Zerkin, who took the picture and tweeted it, describes himself as a wearable computing enthusiast and "prototyper" on his Twitter profile. He said he just happened to run into the most famous piece of wearable technology Sunday and the man behind it.
Zerkin tweeted a picture of his encounter with Brin, saying "Yeeeah ... I just had a brief conversation with the most powerful man in the world. On the downtown 3 train. Nice guy."
The photograph has since gone viral. It's been used in countless news articles and been re-tweeted more than 600 times. It gives us a glimpse of what we might look like in a few years if smart glasses are a hit.
For the most part, Brin's Google Glass just looks like another pair of eye glasses, unless you're looking really close.
Google first gave us a peek at Google Glass in a YouTube video early last year. The gadget seems to have many of the same capabilities as our current smartphones. The big difference, though, is that we see the data displayed from a tiny screen located on a pair of frames.
Unfortunately for Zerkin, however, he was so caught up in the moment that he forgot to pitch Brin on things he's working on.
"Come to think of it, perhaps I should've mentioned my projects to Mr. Brin," he tweeted. "Or given him my card. Derp."
Of course, the big question remains unanswered: what the heck was billionaire Brin doing taking the subway?
