Maybe not in the strict sense, but it kind of has.
In the enterprises I've worked in the past decade with IPv6 running, at least 75% of the Internet traffic is IPv6. In my discussions with other engineers managing large networks, they seem to be seeing more or less that same figure.
The problem is that virtually nobody knows IPv6. I regularly bring up IPv6 in engineers' circles and I'm often the only one who knows much about it. And so, I have doubts about it's long-term future, except for edge cases. I figure some clever scheme utilizing IPv4 and probably NAT will come around at some point.

I challenge you to find:
1. A hotel in the US that provides IPv6. I have NEVER been in one, and I once stayed in a hotel (in Mountain View, CA) that was giving out public IPv4 addresses.
2. An easier task: a SIP provider that has IPv6 (in the US). You know, for the VoIP that is supposed to be a poster child of end-to-end connectivity.

What about those without IPv6 running?
Anyway, in the enterprises I've worked in the past decade - of course, another anecdote - not once has anyone ever specified an IPv6 address of anything. Inside the organization or outside of it.

Nobody cares about those. What matters is if my device has an IPv6 address assigned.
75% or 99% does not matter. Until you can't forget about IPv4, IPv6 us useless.
IPv4s are about to be bought, held, portfoilo'ed, speculated, and rented/mortgaged/sold like real estate. Companies like IPXO are already doing it. The costs of public IPv4's are going to go up for no technical reason because a new distinct ownership layer is springing up between you and the ISP. You're going to start renting them or paying a holder for the right to use them (on top of your ISP to transport it) at some point. And you can continue to do that, or get IPv6's for free.
