In India, a local educator is making efforts to preserve the language of the Juang people — a small ethnic group whose language is on the verge of extinction. To do this, he uses modern technology: recording videos in his native language and publishing them on YouTube. According to the educator, such recordings can become more than just an archive of words and phrases — they can be genuine cultural heritage, important not only for the Juang people themselves, but for all of humanity as a whole. Languages of indigenous and minority peoples often disappear along with their last speakers, taking with them unique knowledge, traditions, and worldviews. The use of video platforms to document rare languages is becoming an increasingly common practice among activists and researchers around the world. This approach makes it possible not only to preserve linguistic material for science, but also to draw wider public attention to the problem of disappearing linguistic diversity. Furthermore, the availability of videos on the internet allows members of the diaspora and young members of the Juang people themselves to learn about their native language and culture, even if they live far from their historical homeland. The initiative of an individual enthusiast demonstrates how digital technology can help address one of the pressing problems of our time — the loss of linguistic and cultural diversity on our planet.
