I don't believe those are valid comparisons or analogies, adn I also don't believe they're actually correct. Apple has an absolutely huge market share compared to 15 years ago Chromebooks and MacBooks are the top selling laptops. Even enterprises are allowing OSX and Linux desktops into their environments and have been for years. Beta was clearly superior than VHS, but the management of that format was handled poorly, it had nothing to do with quality or complexity. Laserdisks were amazing when they were available (and I had a ton of them and loved them) but then DVD made them obsolete because it could do more with less. The same is happening with Blu-Ray.
Things change, especially in tech.
IPv6 isn't an upgrade and it shouldn't be considered one. That would be like me saying I upgraded to IPv4 when I disabled IPX and Appletalk, it doesn't really make sense. While some may see zero perceived value in IPv6, the rest of the planet may or may not agree. And yes, I have noticed that all of the OpenFlow (not SDN) examples still use IPv4, I've been involved since the early days. OpenFlow 1.3 fixes that and it is the version that vendors are moving to. 1.0 is not something I consider complete for many reasons.
See my above statement about enterprise being but a piece of the end site traffic.
Realistically, the internet and networks in general are about both creating and delivering content and services. If the content and users have IPv6, and I think we can agree that both of those cases are happening, we (as a whole) will use it. It's already happening.
