They won't. It will only help accelerate the move towards concentration to national languages (Standard Chinese in Taiwan and China, French in France, etc.) Why would anyone put the effort to learn a "small" language when it can be translated automatically for understanding?
The way to preserve a language is putting humans in the loop. Creating content in that language; interestingly more and more shows are produced in Taiwan in or using non-Mandarin languages as a political way to mark a difference with the big neighbour. And having government support, notably at school (at young age) by allowing partial or total teaching in the language to be preserved.
