I've been watching Isaac Arthur episodes. In one he proposes that O'Neil cylinders would be potential havens for micro cultures. I tend to think of colony structures more like something created by a central authority.

He also brought up the question of motivations to colonize other star systems. This is where my centralist perspective pushes me into the idea of an AGI run government where redundancy is a critical aspect in everything. Like how do you get around the AI alignment problem, -- redundancy of many systems running in parallel. How do you ensure the survival of sentient life, -- the same type of redundancy.

The idea of colonies as havens for microcultures punches a big hole in my futurist fantasies. I hope there are a few people out here in Lemmy space that like to think about and discuss their ideas on this, or would like to start now.
