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

Well the data shows they are in fact using it. Most people use their ISP router which in these carriers would be setup by default to use v6, plus any router bought in the last 10 years would support v6 and probably use it by default.

I'm on a large ISP provider and they do not have IPv6 in my area, a new build with fiber to a access point that turns it to cable on the house. So there's that.

Ah RFoG. It's a weird technology choice. I think it's supposed to be transitional so they get the fiber in the ground now and then can later come back and rip out all the DOCSIS equipment and replace it with *PON

Obviously they are. Most people use the equipment provided by their ISP without ever changing any settings.

If the ISP is IPv6-first, you bet that their customers are using it in their 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.

Came to post that blog. It's awesome. Everyone should read it.
