"Why do I need to change from React.createClass to ES6 classes, from ESxx to Typescript or Flow, from React to Vue, from callbacks to Promises, from Flux to Redux, or from any idea to the next hyped idea?"

There are good reasons for those changes. As you are a full stack JS developer, I'd recommend you dig deeper and find out why. It might alleviate your frustration.
