If native apps had ideas worth stealing the web would have by now.
That said, I don't mean this to be disdain. Having a somewhat targetable VM like environment to deploy applications to is a huge thing. That it has some fairly capable visualization capabilities built in is not a small thing.
That all said, I do think we are still far from how productive a small staff could be with some of the form builders of yesteryear. I'm also not entirely clear those left you with less legacy cruft than the equivalents today. :(
The web was trying to be a connected online media form from the get go. Calling everything but text a hack is a maligning that seems at best a half truth.
Even if it was a "hack," it's been evolved & changed so much. There's been so much experimentation & so much living with hard constraints for a decade & finally making revolutionary change. Flex ix, grid layout, just hundreds of really amazing sweet super well done improvements to css & we components. It's an incredible blank slate that expresses so many really interesting & open experiences & UIs.
I agree with the parent poster & with you. The web has stolen most of the good ideas from native apps. Most of that is via frameworks & libraries rather than the web itself, & to me, it's amazing that the web can keep innovating & changing it's form to meet developer preferences, while the low level "hack" platform remains. That diversity & possibility is a sign of great success, that it can seed such diverse & competent different modes of development so gracefully.
So worth or not, doesn't matter.
