React is all the hype right now. And it is a nice system for creating dynamic single page apps. But there is little reason to use it for static websites, which could be cached easily, instead of rerendering the website on the client with Javascript. And instead of having automatically cached static website, we use local storage and such to get something resembling a cache.
I would love to see some mechanical sympathy in modern web development, instead of cargo culting all the new tech.
