Everyone hailed Minitel in the 1980s. It was touted as an example of what gov't should do (these were also the days of Japan, Inc. kicking everyone's ass, also showing what gov't "should" do for industry). Yet along came the Black Swan of the Internet to slay it. Central planning never works.
Except the cases where central planning works, like (DUH!) Minitel (until the internet came, it didn't fail, it just got upgraded, duh), going to the Moon (distributed attempt at reaching the moon, also known as the living pyramid), justice system (as soon as you introduce the ability for appeal), the Internet, DNS system (it may be not centralized, but it is centrally planned), Google, Apple, and your own consciousn…
I can't tell if the "central planning" you refer to with respect to consciousness is supposed to be a homunculus or an intelligent designer, but either way I disagree.
Brains are pretty well distributed, and various degrees and kinds of brain damage have shown that no specific location is an inherently privileged "command center" of the brain; [different] people have continued to be thinking people without each part of it.
