I think it's just micro-fiction, a 1 sentence (2, if you count the comment) short horror story. The chain lift stops making noise right before the roller coaster car is about to drop. If humanity is on a roller coaster, "the drop" can be interpreted as either the civilizational collapse or as some kind of a Singularity event.
