This is an excellent article and well worth reading. I would have a couple of nit picks with his nitpicks though, particularly: Since the Na’vi have had the ability to download information and share it in a massive network for long periods of time (evolutionary timescales), they should be way ahead of us in terms of technological development. If the movie ever mentions how long the Na'vi have been around as sentient creatures, I missed it entirely. Even if they would leave the "noble savage" stage much faster than humans did, they certainly would have passed through it and if that happens to be when this movie takes place it is hardly surprising. Also, the type of information that they could pass around in this fashion is never clearly delineated. The Tree of Souls can clearly move everything there is from one mind to another, but it is never shown that this can be done routinely or without price, so it may be less valuable in terms of developing technology than it would seem at first glance.
