Everything I know about IPv6 comes from this one blog post: https://apenwarr.ca/log/20170810. It’s from 2017, when IPv6 adoption was 17% according to https://www.google.com/intl/en/ipv6/statistics.html; today it’s close to 50%.
I'd assume a lot of this is because of mobile devices of some type. Getting legacy network operators like cable providers to supply IPv6 has been hell.
Eyeball networks and cloud providers have been implementing IPv6. In the US all major phone carriers are v6 only with XLAT, the large residential ISP all have implemented v6 (Charter/Spectrum, Comcast/Xfinity, altice/optimum). The lagging networks are smaller residential ISP and enterprise networks.
In Asia they've implemented v6 everywhere pretty much because their v4 allocation is woefully insufficient. APNIC has like 4 billion people in it but less IP space than ARIN, with a population of less than 500 million.
Just because the ISPs have implemented IPv6 doesn't mean anyone's home router is using it, let alone all the devices in the home WiFi

In my experience it's actually the large enterprises that are having issues.
Is that worldwide adoption or adoption in the US? China went from almost nothing to 77% adoption is just a few years because they included it in their last 5-year-plan. How much of that adoption would be explained by China alone
Google's stats are Google International, i.e. everywhere Google provides service. Whether that includes China depends on the whims of the Politbüro.
That's the best thing I've read all year. Ok, it's the best thing I've read last year too. I kinda knew all this stuff but I never knew how it all happened. I never thought of MAC as unnecessary in an IPv6 world.
