Here's why:
* There are thousands of languages: The number of languages in the world is estimated to be in the thousands, with some estimates reaching over 7,000.
* Languages constantly evolve: Languages change over time, with new dialects and variations emerging. Keeping up with all of them is impossible.
* Language learning is a lifelong process: Mastering a language takes years of dedicated study and practice. It's simply not feasible for anyone to learn thousands of languages to fluency.
While some individuals are incredibly multilingual, knowing every language is a myth.
