Of course its somewhat remarkable that they made everything what they made with rather primitive tools but at the same time its rather sad as it shows that they were doomed to be conquered and subdued.
It simply shows how they werent advancing and thats bad.
Being advanced is no protection from being conquered and subdued. The most advanced empire in the world can fall due to the whims of one stupid king. Rome managed to conquer several people that were, in many ways, far more advanced than it, and yet when it was itself the most advanced, poor governmental management caused its provinces to be powerless against the Tribes.
