Are you struggling to say that Cuba will blame AI for allowing the USA to beat them to their post-scarcity goals? Perhaps. American innovation is unquestionably leading the way to communism right now.
If communism ever is realized as more than science fiction, it will almost certainly be because of the USA's efforts. There is no chance Cuba will get us there. Of course, their official claim of seeking post-scarcity is only for pretend to keep up political appearances. The USA, in contrast, is actually trying. You might say ironically, but I'd say that Marx just got it wrong and that capitalism, not socialism, is the most likely path to communism.
I suppose in your modern communism they'll blame the "AI".
