It's true that certain top-down structures are great at coordination and increasing efficiency for small changes, but at the same time are creativity killers (because ideas need to go past a few layers, because most new things are not beneficial from the first second thus can be "optimized" by elimination). Or putting things in a different way - we need "noise" to get further of a local optimum, so we can explore more distant (and perhaps: better) optima.
