So, I'm younger, but there was absolutely a shift in thinking from web 1.0 to 2.0 in that 2006-2008 era. You could even call it the Ajaxian era. http://ajaxian.com/

I read that blog every day and the techniques and tooling (jquery/mootools/etc) absolutely shifted the thinking that birthed our "modern" react/vue style single page app.

This is like saying that Classical -> Baroque never happened because people still paint in a Classical style.

No, what happened was that a lot of people said "web 2.0!", a bunch of other people said "AJAX!", and only the AJAX thing actually happened. Web 2.0 meant the semantic web, not the asynchronously loaded web.

For as far as i remember 'web 2.0' meant replicating Mac OS X's Aqua on the web (very poorly, of course) with gradients and shadows (not necessarily through CSS, thanks to IE6, but it helped) and unnecessary javascript everywhere.
