The important part is that it's a bubble you can choose to live in. Companies everywhere use React and almost no one need ever choose to learn something else. As long as you know it you will be employable for another 20 years, just like with Java.
But people in that bubble keep shaming people who aren’t… and react keeps changing, so it’s not like you learn it once, it requires careful study and understanding of all the different permutations that are used in different environments.
You generally can’t go from company A to company B who both use react and have the same calling convention, code structure or tool chains even though they are both using react.
Retention shows a clear trend for all frameworks and even in general conversation Solid.js has been taking up more and more of peoples' attention with signals.
The compound advertisement of hearing about Svelte and why it's always going to be faster than React because of not having a VDOM along with Solid.js will make a dent in React and it will become the next Angular. 20 years is not going to happen.
