There is something unique in web development connotation to the other fields I've worked in. The industry has made a habit of reinventing the wheel in every more complex ways.

My best guess is that this is a side effect of web being a field that's more often picked by new or less experienced devs.

The web is essentially UI development. And UI frameworks and libraries have always had lots of churn. Even ultra-conservative Java has had AWT, Swing, and a couple varieties of JavaFX. And then a few more developed by other groups like SWT. The expectations of both developers and users increase as computers advance, and older frameworks can't always keep up.
