Here’s a great preview video, just released, and that’s trending right now of Google Glass showing more of its features: including the previously un-communicated ability to translate live.

Shopping, in its most essential form is social –  one person buying from another  . But what if they don’t understand each other?

Google Glass to the rescue – with it’s translate feature (check @ 1.42), saving shoppers from awkward moments when shopping abroad in a language you don’t speak.

So if, as Matt Ridley in his excellent TED talk argues, helping more people to engage in commercial exchanges drives social evolution, making societies smarter, more advanced, and prosperous – then Google Glass could be a very ‘social’ product. (Google, do whatever you have to brand this feature as BabelFish; it’s far closer to the original idea than Yahoo!’s web service).
