Not really that dystopian: different cultures we have now, they evolved because people were spread across the whole earth with no means of instant communication. Now that we have Internet, cell phones, etc. we will eventually blend into one culture (over the next 200-300 years). That's not a problem really. What is the problem is people who are impatient, and try to speed up the whole process. Such as current European Union leaders. Trying to force the change, instead of letting it happen naturally provokes unrest, conflict, rise of nationalism, etc.
