In my younger days I thought direct democracy was unworkable, but now I realise that might have just been my brain conforming to the bourgeois representative government status quo.
Obviously we easily have the tech to do DD these days, everyone has a smart phone in their pocket, we could do it instantly and on the go. But how you could manage a planned economy that way I’m not sure.
Interesting points. Something your “tyranny of the majority” comment brings to mind is that it’s extremely likely, in the West at least, that any post-proletarian-revolution society would be comprised of a majority of reactionary/non-proletarian/non-revolutionary people. These wouldn’t be third-world revolutions of the majority of the people rising up against colonial oppressors, the seizure of power by the working class in the imperial core would be of a different character.
We’d still be dealing with a probable majority of the population who are stuck in a capitalist, petit-boug, settler mindset. It would be sort of like the Russian revolution in the sense that the proletariat doesn’t make up a majority (I think we can make a general comparison between the smallholding peasant and the “suburban petit boug” of, say, the USA). That context makes the question of democracy quite puzzling - after a hard-fought proletarian revolution, we can’t simply allow the underdeveloped elements of the working class to vote the bourgeoisie back into power.
