I think the “robot“ thing comes from this thinking that the majority of the cost of the items we buy is the cost to produce the item. Every once in a while, I see someone go though the cost breakdown of an item, and it’s transportation, retailing, marketing, and all the other things that you have to do other than making an item that cost most of the money.
That might be some alternative ways to organize society that could take advantage of reducing those costs, but… I think they’d be so exotic that you couldn’t call them Communism anymore - not in the way we understand it now, and not in the Fully Automated Luxury Communism way, either.
