I kinda disagree, I think people are more pessimistic about fracturing than is warranted. For greenfield work, it seems like people have mostly converged on React and Vue, which are conceptually fairly similar. State libs have changed, but again the concepts translate pretty well. Similarly, webpack is the lingua franca. Years ago, we had a new build tool every week, and multiple competing frameworks (backbone, angular, and ember) with very different approaches.

I don't think any One True Way will emerge. Svelte is coming out to challenge React and Vue, Alpine+Laravel LiveWire/Phoenix LiveView challenges the concept of needing a front end framework, WASM is challenging needing Javascript at all, and Snowpack/Parcel/Rollup are coming for Webpack's crown.
