Every HackerNews post about IPv6 has some of the worst, most privileged, idiotic, vibe-coded, proprietary, ignorant, 16bit, capital-guzzling, unicorn takes I've ever known on the subject:

- IPv6 addresses are too hard to remember.
So? You're not meant to remember addresses, that's why we have DNS, write it down, literally a non-issue.

- IPv6 is confusing and I don't want to learn something new.
That's a personal issue buddy, either start reading or get left behind, that's what you said about AI right? More things than you depend on this transition.

- NATing has solved the IP limit problem so there's no point.
NATing is a plaster slapped onto brain bleed, easy and cheap, but ineffective, it causes a wide range of usability problems, such as blanket IP bans, restrictions on self-hosting, connectivity issue for VPNs both private and corporate.
To make matters worse, the effects are significantly worse in poorer countries, while Europe, China and the USA have a bounty of IPv4s to use (though China's still aren't enough), India has been on critically short supply for a while now with reports of multiple NATed network layers being issued. Imagine if you got banned from Valo because your neighbour 4 districts away got caught cheating.

- We've been trying for 40 years and it hasn't worked so let's give up.
OK, we're going to give up on solving world hunger too then because that's clearly not getting anywhere, and the energy crisis too while we're at it, just shut it all down.
Just because you personally haven't seen the progress or felt its effects doesn't mean its not happening, people smarter than you have been working on this before you were born, and at this rate might continue to work on it after you switch careers to Goose Farming.

- IPv6 hasn't worked so let's just make IPv7.
Insane take, despite how it looks, IPv6 support is extremely widespread and ready to go, the reluctance of big tech and ISPs is purely due to the cost implication and lack of enforcement, creating a brand new spec now would enforce another 40 year delay just to assuage your own personal opinion.

- IPv6 is a security risk because the router isn't NATing.
Misunderstanding of what NATing does. Even with a public-facing IP on every device, ports are still protected by the router's firewall.

- IPv6 is a privacy issue because now you can easily identify every device in a home by its public IP.
A valid concern, if it hadn't been identified and resolved with the Privacy Extensions to SLAAC that randomises your IP address after a set time period, mitigating the problem to that of your NATed IPv4 Public IP, if not making it more private by muddying the telemetry waters.
