It would be too expensive, in a competitive setting, for one company to build up the necessary force to dominate everyone else. The profit margins would be too slim and the company would go bankrupt before it even got close.
Sounds a lot like what's happening to western governments right now.
Right. They tax, borrow money, and print like crazy and they still struggle so I don't know how a private company could manage to do it.
I would say language sets us apart from the animals. Animals have no ability to communicate with each other in any meaningful way and so must act mostly on instinct to survive.
As with animals killing only for food, this premise is also false. The neocortex of dolphins and killer whales (which are, strictly speaking, also dolphins) is more developed than that of a human. Actually, they do communicate in a meaningful way with each other and show patterns of cooperative behaviour which are simply impossible on instinct
Seriously? Where are their advanced societies? Do they have underwater cities?
