It is very possible that the achievements of modernity have changed the game. That said, the game was (is?) rise and fall. Rising civilizations leave a heritage to be mined, so there is an overall direction of rise... but every one of the many scientifically advancing cultures in history has declined. It would be prudent to expect the same for ours.
That said, modernity has almost certainly changed at least some of the rules. Even the term "The West" has become complicated. Our civilization is now essentially global. A scientific invention in France immediately arrives in Seoul. A joke told in Houston is heard in lagos. A book popular here is likely popular there.
The practical link between Rio De Janeiro and Tokyo is stronger now than Baghdad and Casablanca then.
