I both agree and disagree with this take. I started out hand-coding static html pages, graduated to Drupal and Wordpress php stuff circa 2009 (glad that's over!), then worked on a largely server-rendered Rails SAAS in the APM space that I guarantee you've interacted with if you've been in the web game for more than a couple years. These days, I may sling React for my 9-5 but a lot of my personal projects and internal…
Yes "app-like-ness" when that's appropriate. But a lot of the web isn't that. Yet devs / agencies are using a sledgehammer (e.g., React) when a Phillips head screwdriver is what's need. Users get experiences they don't need (nor want). Site owners gets a maintenance dependency they don't want (nor need).
My own team “modernized” a forum/blog tool used for internal documentation by moving a lot of it to react and SPA architecture and added ton of “app like” features, and I just hate the thing now. The old version, which we still run on some installations, is way, way faster, easier to use, more responsive and more reliable.
But hey, it looks so App-like now…
Sigh…
