Think about this. Making language and learning language take us so so so so so long time. But every society has it. Because language was essential ( is this too obvious thing;;? ) . To be fluent in one language, at least we usually have to study for over two years. And then we only can communicate a bit in that language. If someone starts another language from scratch, the process starts again..... like the vast infinite universe !!!
Something nobody talks about is with that lady in the charlie chaplin film. If she had a modern phone THEN WHO TF WOULD SHE BE TALKING TO?? ITS 1928 WITH NO CELLPHONE TOWERS.
