I work in a multi-cultural office and there are many different languages spoken throughout the day. That sparked the question "why are there so many languages in the world?" Because if there had been only one then I would be able to understand everyone without hindrance..

Someone took their time and wrote this article about it, which was a short and good read. TL;DR we speak so many different languages just so we can identify what group a certain individual belongs to http://www.academia.edu/8652559/Why_are_there_so_many_different_languages_in_the_world

It did make me ponder whether the same is happening to all programming languages but the internet suggests the reason why is because they all do some things better than others. It then made me wonder whether all of the programming languages will become extinct one day and we will have one superior programming language to use throughout all software domain. From web sites to mobile apps, car ECUs to washing machine chips - any programmable electronic device basically.

Does anyone think this is possible? If so, what would the implications be?
