Sorry, but I don't see it. While they are busy buying up IPv4 addresses, I'll just be over here moving everything to IPv6 only and not have to care about any of that.

Until almost the entire Internet has IPv6 at the endpoint, you're making your stuff unreachable to most people. You will still need an IPv4 gateway.

I have IPv6 at home now but still don't have it at our tech-oriented co-working space, and I've never seen an IPv6 address get handed out at a coffee shop, airport, restaurant, etc.

An IPv4 endpoint is fine and for some situations way cheaper than having every single host be assigned a public IPv4 address. I am not saying that we are there yet, but I can't see a situation where Amazon putting pressure on the market by buying every available IPv4 address resulting in a response of "Let's give all our money to AWS" and not "let's finally make IPv6 happen."

Good point, but the problem is that the companies responsible for "making IPv6 happen" are not necessarily the same companies who want to compete with Amazon. There's very little incentive for ISPs to roll out IPv6, especially when the biggest cloud providers don't support it. It's a bit of a catch 22.

Yeah, what about the hundreds of carriers that don't yet support IPv6?

Don't we have, for example, a Teredo client baked in into every relatively recent Microsoft OS?

My ISP doesn't support IPv6, but I've just checked and a Windows 10 machine was able to do `curl -6 https://ipv6.google.com/` just fine.

And I think I've heard OS X has something as well... not sure, don't have OS X or iOS devices at hand to try it out.

(On GNU/Linux and BSD machines there's a lot of choices, Miredo, 6to4, AICCU from SixXS - whatever one fancies. As usual on *nix systems, setup is manual, though.)

And it works out of the box? Doesn't Teredo necessitate using a relay (someone to translate to native IPv6) – does MS just have one set up somewhere, and preconfigured?

Yes, out-of-box. Haven't ever did anything IPv6-related by myself on that machine.

That curl command doesn't connect on my OSX El Capitan.

That's like focusing on supporting Internet Explorer 8. At some point IPv4 will become the legacy protocol and supporting it will be annoying and expensive.

That day maybe not be today, but switching protocols is not always trivial, and you should start yesterday.
