"successful global socialist revolution by 2042" means:
workers took control over the means of production in key areas (big factories, real-estate, banks, communication, transport & logistics, ...)
more than half of the world (measured in population) achieved this by 2042 (not simultaneously)
the resulting world-socialist federation has a planned economy
the economy is organized in soviets - planned following the principles of democratic centralism
Update 2025-05-25 (PST) (AI summary of creator comment): If the workers are AI and these AI rise up to take control of the means of production, this specific scenario will resolve to YES. This is contingent on all other criteria for a 'successful global socialist revolution' (as outlined in the market description) also being satisfied.
