Let's give the idea a moments thought. Somehow in the minds of the world's population, while they are sleeping, you replace their language with a variant of English with cultural-specific loan words and extensions (for the closest approximation, think of French/Portugeuse? schooling in the colonies, or in France for that matter). And let's propose we rather brainwash ourselves with 'their' language rather than the other way round, to avoid various accusations. And let's propose we construct great internet firewalls, employ sharp-eyed border guards and have strict controls over the movement of people into and out of the country to maintain cultural homogeneity (look to history for precedents). Practically almost any phrase can be translated into another language with absolute equivalence. A great army of translators translates all significant works of literature and media into the new language. Culture is preserved yet we can now communicate between ourselves better? Any observations? (I'll think about it too.)
