I should be more clear. I mean the dichotomy between a web site that is only rendered on the server (which is not more difficult to build now than it was 10 years ago), and web sites that have significant client-side interactivity (which are usually and understandably more difficult to build than the former). Of course, there are different versions of the latter: you can have an entirely client-rendered site, or a site that runs largely the same client-side code on the server for initial HTML renders (like React SSR), or a site that renders HTML from the server and then has separate client-side code to enhance interactivity, or any number of combinations of these and other approaches.
