Na'vi as post-industrial civilization

[Exoblade]

So this idea has been floating around for a while, that the Na'vi are a highly advanced post-industrial civilization that has forgotten its past. One that uses biological technology and that Ewya is some kind of control system.

Its a cool theory, one that does explain so many of Pandora's convenient evolutionary quirks and Ewya's response in the final battle. On the other hand it probably does undermine some of Cameron's ideas and raises the issue of who is controlling who, are the Na'vi being controlled by Ewya (aka Skynet, the Matrix, the borg etc.)

What do you think about this theory?
