Hm, now that I think about it and watched Ray Kurzweil talking about technology evolution and human's brain evolution, he pointed out that entire nature is hierarchical and our brains evolved hierarchical pattern recognizers. So, the hierarchy is inherent within our ways of thinking... But we are hardwired to develop thinking in more abstract ways compared to previously build abstraction levels. Hence, maybe we will build on top of our current hierarchically based way of thinking and be able to go beyond that frontier of limited, egoistic perception of reality. And possibly such teal organizations are just a tip of the emerging consciousness level we're beginning to shift into as a spieces. Consciousness is not limited by the physicality of our World that imposes hierarchical structures on its matter...
