I think you hit the nail on the head. This article is definitely biased
against modern front-end development for example and recommends HTMX as less "complex", but from what I've seen, using HTMX just trades one form of complexity for another.
This part:
> back end better more boring because all bad ideas have tried at this point maybe (still retry some!)
I entered a Spring Boot codebase recently, and it was anything but boring or "simple" -- everything is wrapped by convention in classes/abstract classes/extending layers deep of interfaces, static classes for single methods. Classic OO design that I thankfully moved away from after college.
I think the author makes good points, but I don't think the author is any different than your average developer who accuses the thing they are not familiar with to be "complex".
