Marxism-Leninism explicitly calls on using technology to eliminate scarcity. That’s what collectivized agriculture and mass electrification were for. Along the development pathway the leadership sort of forgot this because they ran into a lot of problems (not the least of which was an incredible amount of hostility from the capitalist powers).

In my view Zeitgeist was just an update on The State and Revolution, but somehow without the armed overthrow of the government. Like technology will somehow allow us to surpass our class antagonisms and ingrained social structures (eapecially militarism) without toppling the ruling elite. I think it turned out to be a naive view unfortunately.
