That does tend to be how communism works out in reality, power in the hands of one person, but IIRC the original goal was power spread amongst many hands rather than just one, probably the closest that we almost got to that were the Soviets set up in post-Tsar Russia but before they were all infiltrated and overrun with members of the ruling government.
Of course, this being humanity such a form of government would tear itself apart as various factions sprung up and worked against each other rather than for each other. Hence why the 'Dictatorship of the Proleteriat' was turned into an actual dictatorship as opposed to being a phrase indicating the political control by the proleteriat class level. Lenin knew a good thing when he saw one.
I think, honestly, in Europe we're as close to socialism as we're going to get, perhaps in the future we might get a bit closer as we become further interlinked by communications, but I'd have said that was more interwined with direct democracy, which is a system which has its benefits but relies heavily on the information presented to the public being free of bias, which is another problem that we have in this current era.
