> You don't need those in React either.

I mean... sometimes you do, that's why they exist. But yeah, most of the time you don't.

> Whatever you do in Web Components can probably (most likely) be done in React.

Of course! React is a good and powerful framework. But everything you do in React can be done in Angular 1.0 or even backbone.js. As always with frameworks it's about the productivity / performance ratio for your team (or for libraries, the ratio for your consumers).

> After all, Web Components are a solidified 2010-era design.

A lot of the web components related APIs are being actively developed including constructable stylesheets, shadow DOM APIs and more. Regardless, the era of design is not a great point in either the "pro" or "con" column, and is usually an ambiguous shorthand for the actual quality being critiqued.

They exist because they're useful, but you can write traditional React components that look a lot closer to Web Components, if you think that's better.
