What next after react/Next.js in webdev world?

Has web development reached its saturation? The present popular consensus is that "jquery is old, react is new". But as time passes and years turn into decades, the relative difference between jquery and react will become less important, they're both quite old from today's perspective.

Of course, there is AI, data science, blockchain, etc. but those are different fields. Has webdev itself turned into something like civil or mechanical engineering - a matured field with steady work but less song and dance?
