Two years on - what will language look like in 2021?

As 2011 fast approaches I came across this video of us filmed about two years ago. Over the next decade or so I think the concept of language and protecting language will be ever more challenged and discussed. With new technology quickly allowing text to be translated through applications like google translate, and the latest Augmented Reality apps such as World Lens pushing the boundaries of visual translation it seems only a matter of time the spoken word will be translated on the fly as well. So what does this mean for 'language' and preserving the ones culture?
