I haven't completely organized my thoughts on this but
All that to say, I can not see this being about AI (and Gilligan has already said it's not himself as well).
I'd also say it's not anti-communist - in fact, a friend pointed out to me this is one of the only shows that is engaging with the ideas of socialism/communism and offering some nuanced ideas/critiques on what a world like that can look like. Capitalist critique shows are a dime a dozen at this point, but Pluribus is unique in this way.
That would be part or the critique - taking the stereotypical American idea of communism to its extreme and then asking "what's so wrong with this, even if what you believe about it is even true?"
Again, part of the critique - Carol is the chauvinistic American in this story, these are the things Americans believe.
