What about books, talks, blog posts, SO answers, etc?

Is everyone going to rewrite all React literature with hooks?

No rewriting needed. Hooks are just another way to do what was already possible in a more well-defined way. All the content written is still applicable. Now there is just a new way to do things too.

The developers and documentation even advises against rewriting old components with hooks unless you need to.

Technically yes, but what if someone only uses hooks and has never used classes?

And, viceversa, since there is now a lot of people moving to hooks and producing React literature for hooks what if you only have used classes?

So now, to be able to read all the React literature one has to understand both methodologies.

It doesn't matter. A big chunk of the JS community is hype-based.

You're gonna have to learn it eventually to work with other code bases and so on. But the point was it doesn't change existing knowledge, just something new to learn.

So don't listen?
