I think there are a lot of frameworks on the edge of viability, but the bar is a lot higher than it used to be for front end tooling. React(70%), Angular(25%), and a little bit of Vue.js(5%) is the market for front end positions with React owning the Lion's share. There are always new things being built, but being used is different.

The React team has done a great job of being generic enough for a broad range of use cases. As new use-cases arise, someone can build a new framework to support it. SSR has gotten much more popular than the SPA style, and the core React team has moved to support it with server side components.

If they can continue to follow the innovators, React will continue to dominate the front end landscape.
