EgoSystem vs. EcoSystem - lol, that made my day. Very true and decentralisation will be more efficient as there will be less waste due to re-uses.
Like anything in life there are negatives and positives. In this instances the positives far outweigh any negatives.
Eco-egosystems! Lol. I think in the end, it'll be a mix of both. As in, decentralised nodes, but each of these nodes will have their own kind of hierarchy that maximises its own functional efficiency.
