@joepie91 It's a proxy if considered descriptively. But consider it normatively, and you'll get a basic precondition for autonomy: a system that is required to not assume existence of a single centre.
@riley The most obvious example: a P2P system without any kind of moderation or authority delegation mechanism, just direct peer-to-peer interactions, is certainly decentralized.
But it is not autonomous - it does not give people reasonable control over their experience, and the only plausible outcome is widespread abuse targeted at the most vulnerable, because it is a highly individualist design.
