(This post is pursuant to a discussion on twitter.)
Amongst humans, centralized communication, centralized knowledge, centralized control, and centralized power seem to go together. That makes sense, as a lot of what Power is, in these times, is the ability to define what's acceptable discourse: what things are worth talking about, and how they should be talked about.
My history with Power has not been good. I tend to be the person talking about the wrong thing, often in the wrong way.
Therefore, in any group I will tend do better if there's less centralization.
So my bias toward decentralization is self-interested.
I feel only a little shame in admitting that. For some years, my goal has not been to be maximally efficient, maximally productive, maximally anything-that's-externally-measurable. It has been to (1) work the way I like, (2) do that productively enough that people will pay me, and (3) have the leeway to improve the way I work - just because I enjoy improving that.
So I acknowledge that total-utility-as-measured-by-money is quite likely[1:1] maximized via centralized graphs of communication and control, but I'm interested in personal utility for me and people like me.
