They need to come up with an ip solution that is useful enough that people actually want to upgrade to it.

When you compare it to other technologies like https, tls1.3, unicode, 5g cellular, wifi 6, wifi 5 or bluetooth versions, etc. It’s clear that ipv6 adoption is not what it should be if they launched a protocol with clearer benefits to the end user.

It's the Internet protocol. End users are not supposed to interact with it directly.

What exactly would replace IPv6? It's just an implementation detail, but an important one if you want to make the rest of the stack suck less.
