In Only 4% of Languages are used online, Priceonomics reports on the paper “Digital Language Death”, by Andreas Kornai.
The article mentions that the internet is a potential threat to many languages. If a language is unused in this domain, it may suffer a loss of function and prestige.
It makes an interesting point that the internet situation is not a normal case of language decline, but the reverse: whether languages will "establish themselves as viable options for digital use."
In investigating online language use, the article states: "A language’s Wikipedia presence was one of the most important indicators of its ability to leap into the digital age." Which is interesting, considering that Even Hindi Falls Behind.
