the question of "who owns the means of production" i.e. who owns the factories, the robots, the machines, the land?
when the Mode of production is revolutionized (let's say, the invention of AI) then the relations of production inevitably fall out of harmony
This then necessitates a revolution in the relations of production
Good example: If everyone is automated out of jobs, who owns the robots? Obviously increased prosperity-generation shouldn't result in more poverty, more unemployment. Obviously society should be rationally led towards harmony with itself, i.e. the robots should be owned by all of society, nobody should be left behind.
Stalin writes about this in his banger book Dialectical and Historical Materialism.
We need to Model the whole economy so we can expose the relations of production
