There are downsides to any situation. E.G:
- cost
- available resources for education and work
- adding one more obstacles for different cultures to be able to understand each other
I'm french, and in my country, language protection is a big thing.
It's also why we have such a terrible ability to speak english, which create way more problems than it solves.
Language preservation is overrated. Sure, it's nice. But compared to one day, having the entire earth speak the same language, be able to communicate and understand each other better? Small price to pay.
It get why they do it. Mongolia is a very peculiar culture, and I don't think it benefits much from mondialisation. Quite the contrary. And it's a way for their society to break from a painful part of their history.
But to me, it seems, at least on the long run, a step backward. Every time a language dies, like latin or summerian did, we gain uniformity. There are enough source of diversity in humanity to not need to add it to the very structure we use to exchange information.
Granted, the cyrillic alphabet is not very universal, but it is certainly more common than the traditional mongolia alphabet.
Now since I don't live there, I may be missing some crucial informations. Maybe the population still massively use the old alphabet unofficially and it makes sense. Maybe the use of the cyrillic alphabet brough problems I can't see.
So of course, I'm not the right peson to judge the situation.
But I wanted to bring a counter point to this the enthusiastic parent comment. We tend to react in a very emotional way when it's about culture, and I'm not sure it benefits our specie.
