I distinctly remember doing my first reading on IPv6 a full 30 years ago. Since then I've seen some serious pushes to make IPv6 support ubiquitous, including World IPv6 Day, federal government requirements for full IPv6 support, and at least one site that offered unlimited free porn exclusively over IPv6. Despite all of this work, the only success stories I've ever read of around IPv6 have been carriers and hyperscalers that needed IPv6 because their internal infrastructure grew beyond RFC1918 space, and IETF conferences bragging how they enabled some new IPv6 feature... for the conference.

At the end of the day, I don't believe the economics will ever favor IPv6. I have yet to see a widespread problem where the cost of adding more duct tape to IPv4 is higher than the cost of switching to IPv6. With customers not demanding IPv6 capable only systems from vendors, IPv6 support is always going to come second to IPv4, and any other features that actually drive revenue.

Until someone figures out a way to make designing, building, and operating IPv6 devices and networks cheaper than what we already have running on IPv4, nothing much is going to change.

Side note: if anyone wants to read some interesting opinions on IPv6 from the technical side, IPSpace has a ton of great articles:

I believe IPv6 will never be universally used unless there's genuinely no choice for anyone. We're out of IPv4 addresses, but technologies like NAT are making that workable (so far).

But there was always some obstacle in the way, something to be gotten through first, some unfinished business, time still to be served, a debt to be paid. At last it dawned on me that these obstacles were my life. This perspective has helped me to see there is no way to happiness. Happiness is the way. So treasure every moment you have and remember that time waits for no one."

I’ve been adding more and more matter/thread devices to my home and since I’ve seen more local ipv6 addresses I’ve tried enabling Ipv6 fully. BUT, Ive had struggles adding matter devices.

Is this just older hardware choices like we have to create a 2.4 GHz only network? Is the world of devices not yet ready for IPv6? What are your thoughts on it?
