I agree. I dont think all systems require consensus and its likely most things do not. When it comes to things that optimizes for survival, it is likely we will need consensus to be productive.
Consensus only need to happen when we are close to one another. Technology has the side effect of bringing us closer together.
I don't think technology has to bring us closer together.
I agree with you that the current default state is bringing everyone into the same sphere. I don't believe that is actually what we want.
I don't want to listen to every Bob's or Mary's political opinion or outrage take. I'm happy debating with a small group that has agreed upon rules (and excludes people who don't follow those rules). Likewise, there are plenty of political discussion groups that want to exclude me because I don't agree with their rules.
Technology should work to make small, discrete groups able to form while ignoring physical proximity.
