Your industry is idiotic, and would benefit from trying out regular application programming in real IDEs from 2016.
Why do you have to be so vitriolic, on a history and topic you clearly know basically nothing about? You've "concluded" the whole web development industry is idiotic? I've programmed in IDEs galore mind you, and hate web development, but you're being an ignorant ass.
Glorious Visual Studio! I wonder why Microsoft released VS Code with a slight towards web programming? Oh but wait, all HTML/CSS/JS editors aren't "intelligently designed" as you put it, guess that means the makers of Visual Studio are too.
Frankly, I believe the golden age of web design was back when everything was built with <table> and <frame>. All this <div> and CSS and LESS seems like nonsense to me, but I have to deal with it.
So much for the "I hate snide vim lovers", when you basically make the same argument as them, except it's a lot less credible since web programming back then was trash. "T-too many frameworks... libraries... philosophies... this whole operation must be BS".
The majority of front-end web dev work has been easily done with NotRealIDEsTM for a long time with whatever developer tools (FireBug, Chrome Developer Tools) and that's perfectly reasonable based on what the problems are.
You seem to feel a certain pressure that web developers worth their salt need to learn whatever hipster.js that comes out, but really those are just tools that people have built to help you comprehend and navigate the mess that is web development. Just because you see a new JS library doesn't mean you sigh and give up, look at it and see if it seems to fit in with your workflow.
I think you should make an effort to learn a bit more about what you're getting into than just walking in, seeing things on fire, and calling everyone stupid for it. Or don't make the effort, and be a little bit more humble about it just in case.
