I'm not trying to get into a semantic argument. By one definition, almost any web application can be considered a CMS.
I'll reiterate my point: tech-savvy non-engineers are using AI to build the kind of dynamic web applications that many engineers don't want to believe can be built by non-engineers using AI.
One marketer I know built a sales-related application for a niche industry with Claude Code and and has been able to attract a handful of paying subscribers in just a few months.
I'm sure an experienced US or Europe-based freelance developer would have charged tens of thousands of dollars to build something similar, and an "agency/shop" double that. And I'm not sure anything they would have built would have been significantly "better".
I'll reiterate my point too then: yes, and that's not new. There are always engineers selling to tech-savvy non-engineers tools transforming a service based on expertise to a product.
