Thank you so much for your thoughts.

I think if we did do sortition I'd hope processes like voir dire are not carried over. It would ideally just be selected at random. There is still a potential moral hazard of who maintains that architecture and those people could definitely concentrate power around themselves if safeguards are not implemented.

I definitely am wary of advisory bodies for the very reasons you are mentioning. Social capital and expertise would become the new hierarchy.

As to experience being needed for governing, certainly for the current one but I'm not sure I think this system would have things like Robert's rules. In my experience those procedures tend to be bigger barriers (and sources of corruption) than useful tools for governing. They tend to favor privileged people. How we do and create laws would probably change to value common language.

I also don't know if I agree that regular people couldn't think in the longterm especially now that they would not have to worry about getting reelected.

As for referendums yeah the system would have to be adjusted to factor in either sortition run or direct assemblies
