I'm not a network guy, so I appreciate this write up. I've been working in a few different areas of IT for the past 19 years, and IPv6 has always been present in conversations with colleagues, but it seemed to me like it was always some kind of meme, or something too farfetched to be taken seriously... Even today when I try to deploy a VM somewhere (Linode, Vultr, etc) IPv6 is the unticked boxed at the end of the page... Are we anywhere close force-adoption? is this something that can even happen at this point? Is the complete depletion of IPv4 address-space the only driver for change?

I recently moved to West Virginia (fairly rural state) where there's only one real choice for broadband ISP at my house (Spectrum), and it supports IPv6. AWS just started charging for IPv4 addresses in February of this year, though in practice, I think this pushed people to "hoard IPv4 less" rather than "use IPv6 more." I know it's far more common for mobile / cellular ISPs, and I know Apple's been pretty strict about IPv6 compatibility in apps for quite some time for that reason. Seems like a slow march in the right direction, at least from what I can tell.

I think we'll see a long tail of IPv4-only services for a long time, but as IPv6 availability of services ramps up (in turn incentivized by a drastic increase in dual stack or v6-plus-v4-NAT eyeballs), v4 fallback solutions will probably be scaled down proportionally, and quality will degrade with it. "IPv6 is only useful if everybody has it" was conventional wisdom for a long while, but it turns out to not really be true anymore: IPv6 is incrementally useful.
