One Language Someday?

UC Berkeley professor of linguistics John McWhorter writes about Dying Languages and the possibility of a single world language someday:

However, the prospect we are taught to dread — that one day all the world's people will speak one language — is one I would welcome. Surely easier communication, while no cure-all, would be a good thing worldwide. For those still uncomfortable given that this single language would be big bad English, then notice how that discomfort eases when you imagine the language being, say, Lenape (Native American).
