I'd say your comment is not constructive: you're asking me to name all the solutions, otherwise my observation has no merit?

I'll expand a little. Let's take a single example: developing a single page web application.

To know how to do that, I need to learn HTML, CSS, JS Frameworks, web pack or whatever. Linters, preprocessors, package management ....

Contrast that to building flash app where a designer could use a GUI to produce a beautiful interactive app in no time at all.

Yep, we all hated Flash, but in terms of accessibility to creators, it was beautiful compared to the mess we've made.

Aren't you then asking for a WYSIWYG editor or a CMS that includes something like that? Many of those exist and are suitable for a lot of web development. You step into the lower level for customization that is difficult or just flat out not implemented in the higher level tooling.

Also, pretty much anything Bret Victor has done.
