It made me think this world is coming to an awful end
The world isn't coming to an awful end, but it's quite possible that western civilization is coming to an end. The culture borne out of the European Renaissance is ending. Just like the cultures of Ancient Rome and Greece have ended. The high points of our art and culture will live on, emulated by the Chinese and Asians in the new dominant world order.
There might still be time to reverse the decline, but it's going to take quite a while. We've been degenerating for about 30 years now. There was a stretch into the mid 2000s and early 2010s when some westerners were still creating truly good and innovative art in film and music, but today it's almost all completely derivative and uninteresting.
The truly dystopian prediction though isn't that China or some other nation/civilization takes over. The real dystopia is that Artificial Intelligence takes over, and that culture becomes frozen in time. Perhaps we aren't actually degenerating, we're just reaching the natural end point that any sufficiently advanced culture would eventually reach
