I originally thought that this was a neat use of AI, but from image 5-10 it becomes obvious that this is a low-effort vibe project.

Someone fed the original images into an AI and posted the output with little to no modification.

The idea is good, but the implementation does not deserve any praise.

The ideas is great indeed. And you are right, the author did not make any effort to steer the AI towards a better outcome. For example, the "great river" is Danube, it obviously exists today, and it is way larger than what AI has generated. This takes away from the immense scale of the Roman achievement. Trajan's Bridge over the Danube [1] was by far the largest bridge constructed by that time (fun fact: it was surpassed by another Roman bridge built during Constantine).
