Ah the old 'No true Scotsman' argument. Except of course that the centrally planned economies like the Soviet Union were exactly what socialists before WW1 demanded. And what they tried to implement.

If the Soivet Union and friends were not Communist/Socialist then a communist economy simply doesn't exist, and has never existed and we see 0 reason why it would ever exists. And its not even clear what it would be or how it would work. So its completely and utterly irrelevant for any debate in the real world.

Its only in circular marxist self-mastrobation logic to redefine Soviet Union as 'monopolistic capitalism'.

Maybe for Graphics cards, but at the same time, those graphics cards can do things now they could not before so they gained in value.
