I disagree. React it's self is very simple. It's web development that is complicated. Other frameworks that try to do everything like angular are also complicated for the developers. The frameworks that do everything and are easy to use (like meteor) don't offer the extensibility of the more bare bones frameworks. Any web site that wants to grow needs a full control of the stack. Of course, if all you're building is a static web page then I can see just using some HTML and CSS. But if you want to work professionally as a web developer then you need to know javascript and at least one major framework. You can not stay employed as a "full stack dev" if all you do is write an a couple HTML and CSS files and serve them with python httpSimpleServer.
