Trotsky opposed centralised technocracy, and he was right - this was what ultimately killed the ussr, as corrupt and incompetent centralised bureaucracy could not respond rapidly enough or appropriately to external conditions. Production was a mess, goods would be in dire shortage in one oblast and vast excess in another. Those who held the central reigns of power funnelled everything into their own pockets - cf. the incumbent oligarchy.

Had Trotsky succeeded Lenin rather than Stalin, the world might be a very different place today. But he didn’t, and it might not have made any damn difference.

I guess we need to run another experiment.
