Internet redesign

I've been thinking about redesiging the internet.

So far I have a mental picture of: -

1. HTTP removed and replaced with something stateful.
2. Sat a top of a distributed scalable platform.
3. TCP can stay.

Good luck replacing things that everyone uses daily without giving a fuck of how they work.
Computing these days is not like 90s where only nerds used computers, now even my toaster can connect to the internet, making SO MUCH HARDER just replacing ipv4 with ipv6.
Does everyone use ipv6? No.
If a so harmful change like switching from ipv4 to ipv6 is so difficult, think about replacing the protocol, the name resolving system, the markup language (if you really don't want to write in HTML, use CGI+whatever you want) and deprecating ALL THE EXISTING WEB how much would be difficult.
