If this rather healthy viewpoint was more generally pervasive IPv4 
efforts would not be met with such hysteria.

As a protocol and product, IPv6 is a success. It works, its deployed, 
its utilized.

As the cure and solution to address scarcity experienced by network 
users and operators, it has already failed in that goal, repetitively 
and continually.

It was supposed to do that using the additional time CIDR bequeathed to 
IPv4. Fail.

It was supposed to do that upon IANA exhaustion. Fail.

It was supposed to do that upon RiR exhaustion. Annual Fail.

It was supposed to do that prior to commercialization and 
commoditization of IPv4. Fail.

It was supposed to do that before E2E on the internet became a quaint 
historical footnote. Fail.

IPv6 has failed the Internet.

Maybe, hopefully, this is the year or decade it finally stops being the 
perennial failure, but the history of fail induced net-negatives does 
not get erased by eventual success, and worse, the future will likely 
continue to contain artifacts of those failures.

Its not impossible to envision that IPv4 does not ever go away but 
actually gets extended in such a way that it obsoletes IPv6. The longer 
this drags out the less implausible it seems.
