I like that the article present two different points. One is that the Internet is a reflection of the socioeconomic reality of the world. Languages with less, or just poorer speakers are less represented. The lack of representation causes a feedback loop that also makes access information harder for poorer communities. Being aware of this reality helps us to understand the challenges that less connected societies have to work with.
The other important point, is to look forward on how the Internet can help to preserve languages for future generations. We are in an unique place were we can save human culture for future generations to study.
I know the feeling from my travels thru China. I was able to access Internet, but the language barrier was always present. It was an interesting experience to see how many non-English speakers experience the Internet.
