I visited the site that you mentioned, and Irish is "endangered", they say. Yes, it's sad but true that many of the world’s languages are described as being “on the verge of extinction.” But unfortunately, this is inevitable, especially in our era of globalization. Many people start using foreign, more popular language, cause it has its advantages. I live in Ireland, but, for example, I write my crypto blog in English, because that way I can reach a much larger audience. But that doesn't mean I don't use Irish in everyday communication..
