When I attended the Drupal Europe 2018 conference I had the opportunity to talk to Barb Palser of the AMP global relations team. I asked her in an intentionally innocent way: "I thought AMP is supposed to replace RSS, but from the presentation it seems like it's trying to be a better HTML?" to which she replied yes. I acted all optimistic, so she wouldn't be defensive, but this conversation sent chills down my spine and I remember it to this day.
What would it even mean to be better RSS? The idea is sites can preload an AMP page safely so that when you click on it, it can display to the user instantly.
In that specific case, isn’t Barb correct, no chills needed?
With CDNs I can decide which to use for my site, if any. If AMP gets established as the "new HTML", the new way Internet content is provided, then it's under Google's control.
