I'm probably going to sound harsh, but diversity of spoken language is way different than diversity of programming languages or frameworks. We need to have a common cultural ground, a shared language: Esperanto was created because the world was deeply culturally divided at the time, nationalist movements and totalitarian mandate of us-vs-them only worked because you have different cultures and languages competing in the same area. Death of languages is not bad. Having cross-cultural exchange and business links probably is the biggest contributor to world peace, all because of people speaking a common language. Having one shared language has numerous benefits : It increases efficiency by eliminating translation and adaptation to each country: instead of making N editions of something for each language you have one. Lack of cultural barrier: you can read sites/books/articles watch movies without subtitles and dubbing, also making content production cheaper and simpler. News and communications become fast and unimpeded by borders and cultures: no need to translate anything. A standard term for something being as precise as the shared language definition: instead of two languages competing for a descriptor word which covers different areas the meaning is made more accurate by settling on a single word. Less of misunderstanding where content can have hidden/insulting meaning in another language due translation(often a quick translation can have subtle mistakes), Diplomacy and travel become easier, with people less alienated from each other. Cultural differences that depend on the language disappear, preventing bias and prejudice for the unknown and foreign. A great counter-example to "benefits of language diversity" is tribes: they have languages unique for each tribe and constant warfare and tensions: us-vs-them mentality preventing progress and cooperation.
