As an old web developer myself, that surfed pretty much all the waves (No JS, just a Perl or PHP monolith, then JS with XMLHTTPRequest, jQuery, Backbone, Ember, WebPack, Angular 1 and finally React) this argument doesn't make sense. No, there isn't a new JS framework every minute. No, you don't need to learn a new thing everyday. There's really only 4 framerworks (React, Vue, Angular & Svelte, in this order), they pretty much do the same thing (Replace explicitness with declarativiness) and the only thing that changes is how you use them (Which you can learn in less than a week if you're a experienced developer).

The way we do stuff today is just a better and improved way to do the same thing we used to do yesterday, the fact that we have so much tooling is just a reflection of the fact that the web was created to serve documents and now we need to serve apps, so we need transformers along the way that allow for that 100% change of scope. But we aren't changing the base (HTML/CSS/JS, which we should), just the wrappers on top of it.
