While it is true that the Na'vi may not need a lot of technological advances like for example, aeroplanes or ships because they have nature on that side. And it's that very nature that they do not want to upset by cutting down trees and building bigger and bigger colonies.
However, the threat of the humans are very present. And this blogger really just hit me and intrigued me.
With the threat of the humans being so real, and with their intelligence, I don't see why they should just rely on bows and arrows while they can actually build fire cannons etc.
It's interesting to consider avatar from this perspective. Scientist have often wondered about different categories of civilisation. Perhaps they happen in stages. From a roaming family of creatures, to a tribe, to a government, nations, coalition etc.
The Navi would probably be a tribe stage species(not considered a civilisation yet). While it could be concluded that a tribe species is technologically inferior, it is also possible that they may have knowledge that even a civilisation may not have due to differences in the ecology or their planet.
Think about it. If the Navi could use guns, cannons etc, they would need an industry. A system to govern a larger population for mass production and heavy mining(which goes against their tribal philosophy in the story).
But most of the reason why the Navi are the way they are is, I suspect has more to do with it being a fictional story rather than a realistic look at what other intelligent life may be like.
