Great article. The move back to more web standard-focused work has been a joy. I just used the <dialog> element, awesome. Vanilla JavaScript has improved with new APIs. WebComponents are nice, though they are more focused on creating elements on the fly.
With all this there has been an increasing appreciation of static pages - a large share of the web simply does not need backend logic at all. This makes development and deployment trivial, with superb ux performance.
React is an impressive piece of technology, and has its use cases, but as the article states "do not throw away the baby with the bath water."
The only constant is movement.
