I remember when React first came out. I loved it. When I looked back on server side templates I thought they were old, dumb, slow.
Fast forward to 1000s of headaches with state management, repainting issues, slow updates, etc. When I went back to Rails (w/ hotwire now) it was a breath of fresh air.
Experience with complexity leads to appreciation of simplicity. I'm sure more and more people will see the light as they get fed up with current state of "modern web development".
