To paraphrase a bit: Biologists say that organisms do not run themselves in a hierarchical fashion. DNA is in every cell. There is no 'homunculus' in the brain, but rather a 'neural net.'
"Each bit of the nervous system communicates primarily with the bit next to it, and somehow the whole coheres. The neural net, in general form, is remarkably like the markets that Adam Smith envisaged." (1)Many are fascinated by the Internet, envisioning it as a way of bringing the minds of the world together. It seems obvious that the beauty and useful of networks is the discovery of our age.
It seems strange, on the other hand, that our economies are still organised in the same way as in the 19th century robber baron era. Large organisations are demonstrably inefficient (instinctively for those having the misfortune to work in them). Now we realise that they are dangerous as well.
The enormous, "too big to fail" banks are dragging our economies down with them. The "too big to fail" US auto industry is sucking up resources and attention that could go into a more efficient network-type economy.
"...the hierarchical structure of the MICG [monetarized, industrialized, corporatized, globalized] model - everything run by a few corporations, as Egypt was run by the pharoahs is grotesquely out of date. Corporations may or may not be useful but society as a whole certainly does not need them, any more than bodies need homunculi." (2)
