I read comments such as:

>> I don't get it. LLMs are supposed to have 100% bridged this gap from "normie" to "DIY website." What's missing?

as less sincere and more facetious, calling out that every single "AI" company is massively overhyping their capabilities and use-cases. You did the same thing in a more detailed fashion, enumerating all the constraints that AI can't address, and others that speak to the reasons that small businesses don't have websites independently of the tooling/services that are ostensibly able too make it easier or remove barriers.
