And for more often than not, these non-AMP versions are heavy and slow. If you’re reading news on these sites and you didn’t click through specifically to the AMP library, then AMP hasn’t done a single thing to improve your experience. AMP hasn’t solved the core problem, it has merely hidden it a little bit.

Here's a great and in-depth analysis of the performance of Accelerated Mobile Pages by Tim Kadlec. AMP doesn't offer anything you can't do with a proper build process and any CDN you choose. But if you want your pages to appear in the Google search carousel, AMP is your only option.

I don't really know what to think of AMP anymore. I like the idea of making the web faster, but I'm starting to think that AMP is not the way to go. AMP is only useful, if you want your content to be displayed in the Google search carousel. Period. That's it. If you want your website to load fast, just make it fast. You don't need AMP for that.
