I like function components too, but I've seen some interesting arguments against using them:

And I wish I had a reference for this, but I seem to remember reading that any future performance optimizations that could be applied to function components could probably also be applied to class components (at least ones that contain only a render() function and nothing else).

In any case, I'm hoping that React eventually gets to a point where developers don't have to make a choice between class and function components, and the compiler or the runtime makes that decision for us on a per-component basis.

EDIT: As an example, here's a Babel plugin that takes care of the conversion for you at compile time: https://github.com/remcohaszing/babel-plugin-transform-react.... Not sure what its heuristics are for determining what should and shouldn't be converted though, if any.
