What is so great about having many different languages? It is sad when cultural heritage is lost because it was written in a language no one speaks anymore. But this problem is caused by having many different languages. In a parallel reality, where the culture spoke the same language as other countries, the cultural heritage would not be lost. It is sad when a group of people is discriminated or has fewer oportunities, because they cannot use their language. But again, in a parallel reality, where these people didn't grow up speaking a different language, the problem doesn't exist. If you could magically change the world so that it would have 10× more languages, 10× more scripts, and 10× more USB connector types, would it make the world a better place? If not, then why changing it in the opposite direction wouldn't make it better? When a language disappears today, it is bad because we lose information, and because the last users of the language have a problem communicating. But if you could magically change the past to replace that language by English centuries ago, there would be no lost information and no suffering users. And if we could agree on a common language today, we would be magically changing the future just like that. (Esperanto gives the additional advantage of being more regular.)
