I don't know if it is just my experience but amp sites load slower than hn does. Slower than my own websites. Slower than the websites I usually read on.

Sure, amp sites from the feed appear to "work" instantly but they fetch all the content in the background so that's not fair (on chrome at least).

I disagree that amp doesn't bother normal users. It is easily noticeable when you click on a search result and go to a page that says amp.google.com?blah=blahhhh and all that. When, as a normal user, you try to copy that link, you'll end up finding this junk and no straightforward way to see the original link. When you click on a link on the AMP page, it forces a full browser refresh. Sites which force people to use apps don't even work with AMP, because these links confuse the deep linking big time. I haven't even seen AMP pages to be any faster than the actual website itself.

It's because your internet speed is too good to notice. AMP pages are definitely much faster, which you can ask anyone in a country with lousy internet connections about. I'm not saying that AMP is good but claiming it's not faster is just wrong. I also don't see why it wouldn't be. If the restrictions on the stuff you can put on AMP pages together with Google's edge caches wouldn't make it faster it would be strange.
