On the demise of Arabic

"Just how dire is the crisis facing Arabic? Is it in danger of becoming merely a language of religious ritual, as some have wondered, or are these the laments of language purists who, like Ibn Manzur in the 13th century, are inclined to see the glass as half-empty? Arabic is, after all, the language of 300 million people, a language of literature and culture, politics and scholarship, not to mention religion. How could it possibly be in danger of extinction?
