And even if it wins, it won't matter much, since it is only one of many issues with the current Internet that prevents people from connecting to each other. Even with IPv6 you'd still have no way to find the other person and the moment they hop between networks, their IPv6 address won't stay the same either.

Ultimately I think none of this will be solved at the low level, it needs something like Iroh or libp2p where you build a new network on top of the Internet infrastructure, so that you can have things like persistent cryptographic identities and addresses that you can carry with you, largely independent of the underlying network architecture.

I absolutely plan to NAT my home, I don't see a good reason to do otherwise.

I don't see a reason why my machine addresses should change over time... then again, most shouldn't have direct internet access anyway, a http proxy on firewall should be enough.

Well, any 3G or later mobile backbone is SIP+SCTP over IPv6. So in many ways it won already
