Also there is terrible URL usability with google AMP pages. Google has every reason to do away with URLs as a user tool. I might be going off in the deep-end now, but if there are no URLs, why ever leave google.com at all? AMP is basically an early opt-in of rebranding the internet as google.com. Of course its all being done in the name of security, speed, and data-saving. Truly altruistic motivations.
