The findings indicate that language loss is not a modern phenomenon — linguistic diversity peaked at a level roughly an order of magnitude higher than today, and has been declining rapidly over the past one to three millennia. The research combines assumptions about maximum ethnolinguistic group sizes with population estimates to reconstruct this long-term trajectory. ## Full article daily.dev links to this article rather than hosting it.

I doubt that all the languages were unintelligible to each other given that intelligibility is a continuum and the large estimate they postulate (maximum of 40k languages 1000-3000 years ago) > — [fittingopposite on hackernews](https://news.ycombinator.com/item?id=49045661) > It makes sense. If we think about pre-agriculture human societies, you have many small groups occupying different economic niches who may trade, fight, or intermarry with one another but are generally constrained in size and power by a lack of surplus. Lots of opportunity for many different isolated language communities to exist. Sedentary agriculture leads to larger units of society and to more centralized power, which by its very nature erodes linguistic diversity. The existence of trade networks, tax collection, organized religion and the like force people to learn one another's language, and create the concepts of "trade" and "prestige" languages. You can see how this played out in waves in Europe, the Near East, India, China, etc. The remaining places with a high degree of linguistic diversity (in terms of more language families or language isolates) until very recently are those where more traditional human societies lasted longer. For example, Siberia, New Guinea, or Australia and North America before European contact. > — [snovymgodym on hackernews](https://news.ycombinator.com/item?id=49041095) > Human languages aren't just a set of more or less arbitrary conventions relating groups of sounds with meanings. Language is probably humanity's greatest and most advanced technology, making most of the other ones possible. And it's also art and play, a repository of original wisdom encoded in the various etymologies. It steers thinking down certain pathways in ways which are hard to even point to - because it would be a bit like the finger trying to point at itself. They are collectively created artifacts which encode the wisdom of generations. The deeper, wider and more diverse that pool, the more powerful the product. A human language invented by one person or by a group of people cannot ever compare in depth and richness to the languages most people use to communicate and think. > — [pegasus on hackernews · 1 comments](https://news.ycombinator.com/item?id=49041728) > BS. We don't even have training data for the more than 6000 languages in the tail of the distribution. > — [fittingopposite on hackernews](https://news.ycombinator.com/item?id=49045409) > I would expect the opposite, languages converging if for nothing else to please the ear. Just look at unit systems. People go crazy over metric versus imperial units or old outdated units being used. And yet converting between units has never been easier. Many industries invented their own units to fit their use case, but once their products spread to national or global distribution everything gets standardized to the most common unit. > — [AngryData on hackernews](https://news.ycombinator.com/item?id=49045703) **Source threads** - [hackernews](https://news.ycombinator.com/item?id=49038181) · 58 points · 34 comments ## Similar posts on daily.dev - [Medium](https://daily.dev/posts/medium-vrsqfgio1) · Medium · 1 upvotes · 0 comments - [Language Discrimination Improves Linguistic Learning in Multilingual Speech Models](https://daily.dev/posts/language-discrimination-improves-linguistic-learning-in-multilingual-speech-models-szjjq0ump) · Apple Machine Learning Research · 0 upvotes · 0 comments - [AI and minority languages](https://daily.dev/posts/ai-and-minority-languages-fdldafgbu) · thoughbot · 0 upvotes · 0 comments - [Chat, are we cooked?
