Fully agree with how it seems Asimov has misunderstood something, or perhaps been myopic about seeing the world of 1984 with commitment .. another thing that killed his analysis for me was that he didn’t seem to understand the immensely dire conditions of 1984, vis a vis low quality razors, etc., nor that the sociological aspects he implies as banal (implying orwells disregard for proles) were as a consequence of years of brutal war. Asimov didn’t seem to want to scratch deeper into 1984 - he was, I believe, more responding to the world of 1980, which was after all an entirely different yet strikingly similar world to the novel, kind of like political parties.
I have respect for both authors, but for sure I’d rather have a drink and share a sausage with Orwell at a party than wall-flower with the collective absorbing Asimovs rants didactic. Pretty sure the gin’d be cheap anyway.
