Congratulations, you have discovered the fundamental difference between fantasy and science fiction.Well, this just about describes most settings out there.
Just for once I would like to see (or perhaps even make) a setting where the base assumption was the opposite: "The world is, and always has been, on the ascendant. We can do things just as well now as they did in the past - in the past things may have been done differently, but not necessarily better. There have been no great catastrophes in the past, no prolonged periods of decline. Empires may have risen and fallen, and invasions may have occurred, but these were merely temporary setbacks to the inevitable march of progress. All races rose about the same time and share in this progress; elves and dwarves are not 'elder races', whose civilizations rose and began to decline before humanity's civilizations blossomed. They started up about the same time as humanity and share in the world's progress; their cultures are more vibrant and active now than they ever have been, and if not for their relatively lower birthrates they might threaten to overshadow humanity."
And also fantasy and reality.
