I believe that's in the eye of the reader.
As time passes what was once considered a vulgar expression (e.g., "it's" instead of "it is") becomes standard, and what was once a common expression becomes less and less used, and later it's considered archaic, and associated with culture and sophistication (because only highly educated people would still remember and use such phrases).
The net result is that what was written in a common speech hundreds of years ago may now sound unbelievably sophisticated and downright poetic.
However, in several hundred years, I'm sure teachers of English will still be decrying the decline of the English language. "Do you know what they said back in the golden days of the internet? They said 'Fuck it.' Now look at it and admire the sheer effectiveness of the expression, economically conveyed in just two words. Cannot find such eloquence these days," they will lament.
