There are now more than 7,000 languages in the world, but only more than 10 are spoken by the largest and most widely spoken. By this century, more than half of all languages will have disappeared, and 80 to 90 percent will be extinct within the next 200 years. With 80 percent of the world’s population speaking 83 major languages, the dominant language is devouring more vulnerable languages, and language seems to be going through a unification war! So which language will eventually unify the world’s languages?
So which language will eventually become esperanto in the future?
The answer is that no other language can do that.
In the future, although the number of people learning a particular language will vary and decrease, it will only play a secondary role in the eventual unification of all languages into esperanto.
If English is to become esperanto, it will have to be an english-speaking country to rule the Russian arabic-speaking region of China. Chinese will not become esperanto unless the Germanic and Slavic peoples give up their languages. These are all small probabilities for the foreseeable future. Therefore, no language can replace other languages as the only esperanto in the future.
