In all probability a new language would emerge. But just think of the cognitive load in knowing every single language. Ignoring the many and varied grammatical rules that languages have for a moment and just consider vocabulary. Lets say you need around 3,000 words for a normal day to day conversation (though I suspect that it might be higher). That 3,000 words in Chinese, 3,000 words in German, 3,000 in Farsi. You get the idea. There has got to be more than 2,000 living languages in the world - admittedly some of them have only a handful of speakers - so you will need to remember 6,000,000 vocabulary items. That alone is a nightmare but remember that not all words have direct translations from one language to another, English does not distinguish gender the same way that Arabic does. Japanese has different number words for different types of objects. So where some languages use only one vocabulary item others will require several. English has, as I understand it, the largest vocabulary with more than 300,000 items (we didn't just steal people countries when we built the empire we stole their words too). Take it from me, no one knows them all. 6,000,000 - you don't stand a chance.
