Don't worry. React isn't going anywhere.
It's as if all those large companies with enormous Angular codebases didn't even exist.
It only means that we, as the JS community, are continuing to fail with presenting an alternative to PHP and JS.
I would like to see a backend framework similar to Laravel (/Rails/Django). I'm not quite sure why there isn't one in JS but it would be a big productivity boost. 90% of PHP development will be either Laravel/Symphony, Wordpress or Drupal.
