'Most of the tools we use today didn’t even really exist a year ago: React, JSX, Flux, Redux, ES6, Babel, etc.'
ES6 is a new version of the language under discussion, Babel is a tool to allow you to compile code written in the new version into the old version. The other 4 examples are all closely related to each other, if you use JSX and FLUX you use React, if you use Redux you probably use React.
In other words while I believe fatigue exists and is probably warranted, these were bad examples of what would cause the fatigue.
