I've spent years watching kids struggle to learn English in school while their native languages fade at home, and I think that's a real problem, not progress. When a language dies, it takes centuries of unique ways of seeing the world with it—like how some Inuit languages have dozens of words for snow but no word for 'time' as a separate thing. But honestly, is there a practical way to stop it when every job listing, research paper, and YouTube tutorial expects you to know English? I'm not saying we should burn the global lingua franca, but I wonder if bilingual education plus real incentives to keep heritage languages alive is too costly for most countries to sustain.
