Language as a whole offers a solution to the communication problem, in fact the most effective solution yet.
A compelling argument is that because the parents of a generation passes on a shared common language to their children, that the language will grow healthily into the new generation.
While this is true, what happens when the generation of parents pass on an altered common language, simply put, what happens when the language ‘evolves’ and grows locally instead of globally? This means the solution to the problem becomes localized, eventually spawning a new dialect or pseudo language with its own mannerisms, terms, words and even slang.
A language is roughly defined by how we use it and there is no imperial arbiter of the English tongue to keep these ‘variations of literary and vocal -topology’ in check. Attempts have been made but ultimately a static and or final result of such attempt will become a relic as the language progresses.
Nonetheless an antique language can still be significant through heritage. A lot of scientific terms are inherited from the Latin language which isn’t spoken widely anymore. It now works as a base to trivial scientific concepts and theories. If we follow the science, we can see the historical significance of Latin that is still very present in the modern English language even after Latin has died out.
I read somewhere that 90% of scientific research papers are first published in English and then maybe eventually translated into other languages. This implies that whatever happens to English it will ever truly die out.
