Language is a tool to facilitate information exchange. It doesn't matter how "superior" one language is to another for any given reason, if a language provides limited opportunity to exchange information then it is not valuable. The incentives to learn English exist because the value of exchanging information in English is strong in the present-day sociopolitical context, and the malleability of the language played a large role in making that so as cultures and languages blended together in early day America. When translation becomes effortless and/or integrated into society in a near seamless fashion, the distinguishing value of information exchange in the spoken word will be diminished. I have no speculation on the long-term prospects of the written word.
This is a good time to say that I'm not an expert, just a speculating Internet guy who has read (and listened to) relevant information from time to time. If anyone finds this kind of conversation interesting I highly recommend checking out The Great Courses "Language A to Z" audiobook / audio lecture series. It's incredibly fascinating.
