The existence of nationalities in the future does not mean culture has not adapted of changed over the centuries. I would hope some of our more negative cultural practises would be dead in the water in 300 years. E.G The end of child marriages and females being treated less than equals in the Middle East and parts of Asia.Not mocking (not deliberately), I thought more a statement that Cuba hopefully won't still be under a version of it's current governing system in the future and things will be better. Perhaps there will be areas of Earth which are prosperous today won't be centuries from now.By the example of Kirk (the American guy), and Picard (the French guy), yeah I do exspect that.
