This comment is extremely prejudicial[1]. Not only is language a part of people's heritage and culture, which in itself provides value, but also what you've said is incredibly biased and also simply incorrect. For example, both Mandarin and Spanish have more first-language speakers than English[2]. Almost 40 languages have over 50 million speakers, each.
Hard disagree. It is not standard in many parts of the world, it is the cultural identity of many places, and the costs and logistics of changing everything around the world would be asinine. Language is also sovereignty.
On a more personal note, most of the great classics in all forms of art are not in English.
