> Chrome for Android already modifies the address bar on AMP pages How does it do this? The URL looks totally as I'd expect (google.com/amp/) - I'm on version 84.0
They are boiling frogs: https://en.m.wikipedia.org/wiki/Boiling_frog Little changes over time, so you don't see the end game right away. Signed exchanges and further hacking up / hiding the URL will come. This change only hides some of the URL, with a hover action that shows it again.
Disconnecting content authorship and publishing with hosting so that literally anyone can host web content securely is fantastic!
* Want to bootstrap your IPFS network? You can safely and securely host a huge chunk of the web from big publishers on day 0.
* Want to compete with AMP? Now you can because AMP isn't special anymore!
* Are you a small ISP that wants to cache web pages close to your customers to reduce bandwidth usage?
* Archiving website has never been easier since they're already bundled and packed.
We've already reached the point where the content you're seeing and the server you're connecting to are completely disconnected. Signed exchanges just democratize the process instead of requiring every publisher to pick a CDN.
