He appears to confuse socialism with communism.
It is actually a paradox that communism or in modern words post scarcity society has high probability of being built through AGI, because when you drop 90%+ population out of possibility to be employed due to intelligence lower than chip running AGI, then you either need to give them money as UBI or make basic services free as was main aim of communism.
I actually think pointing this out is a tell of how unread a person is on the subject actually. I can't even count how many times I have read this statement online in my life.
In everyday use though outside a Marxist philosophy circle, socialism is used as a blanket term for collectivism of all sorts and communism is the pejorative word for the same thing.
That's not what I wrote and not what parent poster wrote.
