akperma> So stop worry, and say Baruch ha-Shem that Lashon Kodesh is a living language, richly able to absorb new words, and never suffered the fate of Etruscan or Minoan Linear A (languages which never get butchered).
excellent point. BTW, I think theory says that language changes more in the center while preserved more in far-flung provinces. That is why, American English is closer to old English than British (excluding NorthEast that continued communicating with Britain and getting new sounds from the metropolis). This might explain relative fidelity of Teimeni Hebrew.
But, generally, Hashem put us in this world to develop it and humanity, with some side turns, is successful at that, and the language is supposed to give us tools to reflect current reality. Gemorah is full of words related to agriculture. Surely, Amoraim of our times would add words related to math, chemistry, computers, and AI.
