Roll to disbelieve on this one. There's no way that creating something like WordPress 20 years ago, before any modern-day web application frameworks, was anywhere near as easy. I'm not even talking React/Next or whatever - this was before RoR, before Django (or at least very early versions of both).
I think it's pretty impossible to look around and not notice that technical advances have improved a lot of things in the world - why does it sound credible that programming itself hasn't improved at all in twenty years? Even look at languages like C++ today compared to 20 years ago, they're massively different - do you think all those changes to the languages are neutral or negative in terms of productivity?
