This still doesn’t explain what “the backward group” has to do with generative AI, which didn’t even exist in Mao’s time. Hell, he says in the passage you linked:
The leaders must therefore be skilled in uniting the small number of active elements around the leadership and must rely on them to raise the level of the intermediate elements and to win over the backward elements.
(bold emphasis mine)
So he was specifically in favor of winning over the “backward elements”, which contradicts with your implication that AI as agitprop is “unwanted by people” and somehow bad as propaganda because it would only “be effective agitprop [for] the backward group.”
And…people don’t want it. The only people for whom it would be effective agitprop are the backward group.
Russia is not imperialist: https://en.prolewiki.org/wiki/Imperialism#Russian_"imperialism"
Having some global influence and a capitalist model does not automatically mean you fit the definition of imperialism. You could try to argue current Russia might have the potential to become imperialist given the right circumstances, but short of them losing their sovereignty to the western empire and becoming a puppet state (and therefore only imperialist in the sense that they are part of the west’s empire), that seems like a snowball’s chance in hell. Russia is currently an important actor in a newly forming multipolar world, which is in direct contradiction to having monopolistic capitalist power. And it is “socialism with Chinese characteristics” China, with its fast-moving advances, increasing mutually-beneficial ties with other countries, and powerful forces of production and supply chains that is the dominant force in that multipolar push for sovereignty and self-determination, not Russia. So even if Russia were trying to do some kind of 5d chess maneuver to become a global imperialist power, they would have to go through China to do it, which is where some of their most significant support comes from.
There just simply aren’t the conditions there, as far as I can tell, for Russia to independently develop into the kind of domineering power that the west has had, part of which was built on the tendrils of colonialism created over hundreds of years and then further developed on the advantageous technological and productive position that the US was in, in post WWII; and those US conditions were owed in part to it suffering so little damage to its own country while other places, like the USSR, suffered incredible losses. Russia is again suffering losses for fighting against the puppet/proxy state Ukraine and its neo-nazi and NATO-backed fascist elements, so that they don’t get NATO knocking at their door, coming for them next. This is not some easy war that simply wins them territory and resources, and loses them little. You don’t have to like Russia’s leadership at all to recognize that this is a part of the ongoing existential fight for sovereignty against a brutally expansionist western empire. It was the west that invaded the USSR in its beginnings, it was the west that sought to destroy the USSR and successfully did so. It was the west that couped Ukraine. It was the west that sabotaged peace deals between Ukraine and Russia. The same west that has been doing constant wars, coups, economic sanctions, and other forms of waging war against the entire world for decades, killing millions, just in post-WWII. Not even counting the damage done via colonialism if you go back further. Any attempt to make equivalent Russia and the western empire is nothing short of the most high grade, top of the line BS, and most likely comes from western imperial sources who are trying to flip the script.
Critical support means what it sounds like. It means you support but with caveats, not that you give unthinking support. It means you recognize that the world is not a Marvel movie, but instead has complex contradictions and factional crossovers. That it is not made up of perfect victims and cartoon villains, but of varied peoples and cultures who don’t all have the same interests, and you have to engage with and navigate that in order to develop toward global communism and a world free of imperialism. You can despise it all you want, but you still have to engage with the realities of it in all its messiness.
