A transition that was estimated to be completed in the mid 2000s if memory serves and at this rate at least another 20 years unless IPv4 is retired which imho would be unlikely.
It has a 30year headstart over any other pretender, like this IPV8 proposal. IPv6 migration will be at 99% in 20 years time and another wishlist IPV8 proposal will not have gotten off the ground properly. I don't think anyone has the stomach to go through this change again. Promising backward compatibility is being like a populist politician promising jobs and cars and free medical for all. It ain't gonna happen. With a little help from Google, Amazon, cloudflare etc. starting to deploy ipv6 only CDN's and youtube caches etc. people will be moving by themselves. The benefits are there for the big players, and you'll want to follow.
