Why are Cajun French and English dying languages?

So I have been reading about Cajun French and thats dying because of language shift, where the language is not being passed down to younger generations. Language shift is where a generation speaks a language, then the next generation speaks the native language and also the language of whatever place they are living in, and then the generation after that loses the native language and speaks only the language of the new country. And when a language loses native speakers and is not used in everyday life it stops changing and subsequently dies.

Dialects arise from pockets of people being isolated from larger population. Cajun French came from French speaking settlers in the New World who’s language evolved separately from the rest of the French speaking world. Now that people can travel and communicate to anywhere in the world this sort of isolation no longer occurs. I would expect all of our current languages to evolve into a single language in the coming centuries. The rate that languages borrow words from each other is quicker now than ever. A while back I noticed that I was seeing the German word schadenfreude (pleasure in the misfortune of others) more frequently and had to look up it pronunciation. I expect all the languages to slowly form one.
