Don't get me wrong I LOVE the user experience of the loading but everything else about it, in my opinion, is very negative. You can't even share it like you normally would on the web so it breaks the web in far too many ways just to hard code Google analytics / ads into the website.
I can't check right now but last I looked you can't share AMPed search results and I thought a few pages depending on how they were structured. I could be wrong but I don't remember being able to generate a good URL from some AMP pages.
